Hey dude hope you're using Jack stands, and not just a jack... good way to lose you're legs or more.
Mechanics 101 rule #1
Just to let people know; the crankshaft pulley bolt is a torque-to-yield bolt and MUST BE replaced with a new bolt. These bolts are one time use only. If they are reused they will most likely fail and cause a lot of damage. This is especially true if the car is making more than stock power levels.
Where do i get a new bolt
where am i supposed to get the new bolt??????🤔
just do it up with inpact gun
Best near stock engine modified Cruze I’ve seen!!
did u used a crankshaft tool to install the seal or can be done without the tool ?? im about to do the same in mine but im not sure if that tool is really need it
good vid but got a question. I have 2016 cruze with 1.4 ecotec but i have the Newer Model eng thats in the 2017. It doesnt have a spark plug coil pack like other 2016 cruze but it has individual ingnion coils. Would you know what the torque specs on those coil bolts?? Thanks
did you ever have any issues with the crankshaft bolt?
Does it needs to drain the oil first before doing this replacement?
Question my rs 2013 make a noise when i turn the ac like a chirping noise just when the ac compresor is on and when i shutt off the car make that noise also could be the same issue for the seal? And what brand and the part number for the bolt of the pulley please
Is that seal rubber or metal? And can it fall out if it's bad??
im wondering if i can get away without pulling the wheel and fender well cover and do it that way might make less work
Good luck, only other way is getting the motor mount off
new link for the crankshaft pulley bolt?
Can oil leak from the crankshaft?
I got the same problem on the seal crankshaft also on the side of motor by crankshaft
Could this cause your car to jump a little as well? Basically, When my turbo starts to build boost that's when it starts jumping. I just replaced the PCV disk (Valve cover) and it fixed the spuddering. There was a squeak but not as loud until I replaced it and it didnt jump like this before I replaced it. But when I pull the dipstick out the squeaking stops. I'm really confused on what to do.
Yes, it’s a vacuum leak at the front crankshaft seal. The “chirping” is air being pulled past the seal and it goes away when you pull the dipstick because your releasing the negative pressure inside of the crankcase.
It’s gotten worse because now the “rupture disk” in the valve cover is working properly and the crankcase is under much more vacuum so it’s pulling more air past the crankshaft seal.
I’ll break it down, your rupture disk in the valve cover failed(most likely due to a faulty intake manifold). Since the rupture disk wasn’t working properly(regulating engine vacuum) there was excessive positive pressure building up inside of the crankcase under moderate/high engine load, that excessive positive pressure build up inside of the motor was enough to push the front crankshaft seal out of place and vent the excess crank gas through the seal. Now that the seal has been popped out of place and the rupture disk was fixed unmetered air is being pulled through that seal.
You are a blessing. I was 30 minutes from buying a whole new turbo system. So that will cause it to jump a little too? Kinda like a misfire type feeling?
If it’s making that sound, do the front crankseal AND the valvecover at the Same time, don’t forget to check for the orange nipple in the top middle Port on the intake manifold if you can’t see a nipple sticking out then replace the intake manifold first and then the crankseal/valvecover.
Absolutely, ANY unmetered air(leak) will cause the engine to run extremely rough and experience misfires(DTC P0300).
Is it a reverse thread or not on the star bit bolt? The E18
It is a normal thread, righty tighty lefty loosy lol
How do you tighten the bolt without the pulley moving as well
Thiiiiiss
6pt 14mm fit perfect.
How did you pull that crankshaft pulley off?
It just slides out, nothing holding it in but the balancer bolt.
would that cause a P1101 code & P0171 if Air got in? I bought a new MAS censor & changed a hose , new PCV Valve (cover)...but there is oil leaking from that seal area as well...& i still getting the codes. Would oil & air leak cause the MAS sensor & lean codes ?
Yes, air leaking through can cause a lean condition Code and the oil leak is most likely because you have an air leak somewhere.
I found the most effective way to check for air leaks is with a propane torch. Crack the valve on the torch so a little propane is coming out(DO NOT LIGHT THE TORCH) and run the nozzle all around where you expect an air leak. When you are over top of the leak the engine RPM will increase due to the propane gas being sucked in.
Question mine is still making a chirping noise and they replaced my valve cover and gasket. Why would it make this noise still if that was replaced shouldnt the noise stop?
Breanne Hall Bad PCV will cause a vacuum leak.
Where your pulleys soaked with oil?
I got my pulley bolt out with a 9/16 socket
12 point sockets work! seen it
Go to harbor freight and get a set they're cheap and won't round your bolt
What did you use to holt the crank pulley to torque it
I used the Crankshaft locking pin that locks the crank at TDC. 1/2” bolt will work just fine as well if you decide to do it that way.
William Cochran where can I find more info about this?
Do you have a part number for the pin that locks the harmonic balancer? Or does any bolt that fits work?
Any bolt that will fit will work just make sure that once the bolt is in there is no back and forth play in the crank.
You can get the whole kit on amazon for $65.
@@Klean-Kut-LLC thanks
👌🏼No problem man, let me know how ya make out or if you need any other info✌🏼
@@Klean-Kut-LLC im gonna do PCV fix first then do seal after. Traveling for work, keeps me busy lol
thanks muckh mate
No problem👍🏼
Does the pulley come straight out after bolt is taken out?
Yes, it should slide straight out.
It won’t even budge with an impact with an E18 on it
Do you need any tool to remove the pulley?
No, it slides right out. No special tools are required.
You will need an extremely powerful air gun though.
Okay thank you so much!!
No problem.
What was the chirp sound? Having a similar thing now. What it a rhythmic, regular chirp, chirp, chirp sound?
It’s sporadic, there’s is no pattern to it and it is very annoying. It sounds exactly like a squeaky serpentine belt but it is not the belt. Most of the time it will happen when coming to a stop from moderate/ heavy throttle driving. The next time it starts making the sound pop the hood and pull the dipstick out, if the chirp sound stops that will verify that it is the front crankshaft seal.
If it does stop when you pull the dipstick and it is in fact the seal. Check the hole on top of the valve cover for a vacuum leak and if that is sucking air then remove the PCV hose on the top(middle) of the intake manifold, shine a flashlight in the hole and look for an orange nipple, if you can see an orange nipple sticking out then you can replace the valve cover and Front Crankshaft Seal, if there is no orange nipple in the hole on top of the manifold then you should start by replacing the intake manifold, valve cover and the front crankshaft seal.
Hope I could help.
Does it go away if you pull the oil dipstick?
It should, when you pull the dipstick your relieving any kind of positive or negative pressure inside of the crankcase. If it does stop that’s indication that the sound is coming from the crank seal and also indication that there is a malfunction somewhere throughout your PCV system.
Angela V Pierre mine was the valve cover needed to be replaced and then that chirp/hissing went away
William Cochran its the valve cover needs to be replaced
Will it leak oil if i had just recently did a fresh oil change? Like if i wanna change the seal. Or do i have to wait to drain it, then take the flywheel off?
No, it will not leak oil. You can change the front Crankshaft seal with or without oil in the pan it will not make any difference.
What size socket did you use to take the flywheel off?
mindseeker it is an E18 reverse torx socket. Do not try to use anything other than an E18. A few other sockets will fit pretty snug and feel like they might work but trust me they won’t. I tried it and stripped the bolt my first time doing it and had to hammer an e18 socket onto it and pray to god i didn’t strip it too bad. lol
Ok. Thanks for the info. Haha
No problem, let me know if you need anything else
was it leaking oil there ? is that why you changed it i have a leak and cannot find it lol
Yes it was also chirping really bad, I had oil leaks all over the place but what do you expect with 2 cracked pistons...🤷🏼♂️ lol at the time I didn’t know they were cracked. The engine is completely rebuilt now though.
@@Klean-Kut-LLC weren't those cylinders misfiring then?
Chris Sutton yes, all over hell and back.
@@Klean-Kut-LLC I realize I have positive crankcase pressure... I'm pushing oil out the fill cap, the crank seal, the dip stick.. what a mess.... I have to change the intake, I'm not seeing the check value in the intake. 😤😤😤😤
Got it out with 14mm impact gun
Do you know where the cranskshaft sensor located at.
Yes, it is on the driver side on the back of the block just above where the oil pan meets the girdle. I can make a quick video tomorrow showing exactly where it is if that will help you.
The Big Single Cruze much thanks and would you happen to know why will it give me that P0335 error after putting new intake manifold.
Not sure if it would have anything to do with replacing the manifold but I would start with replacing the Crankshaft position sensor located where I just described.
The Big Single Cruze I found it where u told me and I ordered the sensor.
Let me know if it fixes the issue when you replace it.
why do you have to take the motor mount out ?
you have to remove the motor mount to take off the serpentine belt
I cant believe you put that big ass turbo on that little pos engine!! That whole car needs to be thrown away at 100k miles
Very informative !!! 😔
I pulled the dipstick out but sound did't stop. What could it be?
Front Crankshaft seal. Our engines pull anywhere from 18-22 inches of vacuum at idle. It can still chirp even when the dipstick is pulled out.
It sucks air in not push air out due to the high vacuum the engine creates that causes the squeaking chirping noise.
Yes but in order for the oil seal to allow air to be sucked passed it(engine under vacuum), it had to have had an excessive amount of positive pressure at one point or another in the crankcase(orange check valve inside intake manifold sticking). When that check valve sticks in the open position(as if the engine was idling) and you start making boost all that positive pressure is forced back into the crankcase through that little hole that the check valve is supposed to be closing. Now that you’ve pressurized the crankcase to at least 16PSI(even higher for those of us that are tuned) and the oil seal has been unseated due to the excess pressure when you come back down to an idle and that19-22 inches of vacuum is applied to the back side of the seal it sucks air right by it.
I can’t remember what I said in the video but yes I know the chirp is air being pulled past the seal, just wanted to explain how it gets to that point.
Who did the custom turbo kit?
I did all the fab work myself.
The Big Single Cruze How much power are you getting to it?
IDK why modified a 1.4
You don't show how you put it in!!! What is the point???
I am sitting here thinking it is a stock cruze, jesus haha. Is that two turbos I see?
Looks like a race car engine..
Wtf is all that setup on that engine?! That's the biggest hardware I've ever seen on a Cruze!!! Not used to seeing a small 1.4 built up like a V8 like that!
Why the hell doesn't anyone show how they got the bolt out? Thumb down.
Sorry, but I didn't see a jackstand holding the car, just the jack. Unless it is a locking jack, I would never work under a car without stands. I have heard too many stories when the car fell. Being a licensed mechanic, I believe in safety first
No there were not until recently and no it wasn’t a locking stand and I couldn’t agree more but at the time I didn’t have a set so instead of jackstands the only other thing I had laying around were four 12”x12” cubic inch stainless steel solid blocks that the front of the car was sitting on which seemed like a pretty stable substitute for jack stands. I appreciate the concern though. BTW I’ve recently purchased a set of jack stands rated for 5,000lbs(car is only a little over 3,000lbs) and have since retired the good old solid stainless blocks.
@@Klean-Kut-LLC i usually just use some old wide steelie rims from random trucks, i keep around for stands. as long as they're laid down the long way, not like standing up lol. ive seen people try and use rims the standing up way, pretty sketchy imo. when theyre flat they wont tip. Used to work in a junkyard and found rims or rim stacks welded together were great. Plus you dont have to worry as much about a jack stand tipping from sideways force. good vid.
Ya know, it is people like you that do not do safe things that make me get called in on call in the middle of the night to fix your leg in the OR because you could not take a minute to put a jack stand under the car. But again, I guess that is the security people have when they think that health care is a right vs a privilege. 'its ok if I cut my leg off, because I know I can head to the local hospital and they will fix me right up.' Just like those skate boarders who break their ankles because they are not the ones who have to come in and fix people. Or those stupid drunks that pull me out of bed at 3am because they were drinking and driving and wrecked their body.
It would have been physically impossible for the car to fall, there were 12”x12”x12” solid stainless steel blocks under both sides of the frame which the car sat on for 10 months while it was being rebuilt.
I LOVE IT!!!! Dumd Ass Tech's!! Thank's Doc.
That's right it is stupid people like us who PAY you an obsurb amount of money to wake up and come fix us up at 3 a.m.. Last time I checked nothing in America was free. So if you have a problem with that do NOT accept our money and stay in bed. By your comment you lack logic and think off emotion, spend time with your A/P department and check out those bills that YOU send us for your services. Imagine Mcdonald's CEO complaining about being open late and serving food at 2 a.m. to teenagers. You are not a charity, you are not a hero, you are a in a business.
