damage valve guide is very tricky when it come in rebuilding head,never know how long the new sleeve will last.,,,now we know that bronze is wrong > great video thanks
Yes.
hats off sir
Hats off? But my head is bald!
Excellent investigations and a very tricky situation! 👌🏻
thanks for watching and commening on my channel.
@Kason Lyric Not a sponsor! :)
i guess I'm quite off topic but does anybody know of a good place to stream new series online?
@Maurice Jay I would suggest Flixportal. You can find it on google =)
@Alejandro Xzavier yea, have been using flixportal for months myself :D
Thanks!
Great Video! What year is the VW Tiguan you were working on?
I have a 2000 jetted tdi. After every start the turbo boost doesn't kick in until rpms reach about 2250.this is a consistent thing happens every time for the last 30k miles at least. Once started and revved to that 2250 rpm the boost is there immediately until shut off.then the process starts over again.
graph boost as shown in tdi P0234 video. Diagnosis is a process of collecting information. Just describing what its doing isn't enough, but I would guess you have a overboost code.
Very interesting, I have a headache though. Been trying to diagnose for many hours.
I have a cylinder 1 misfire condition. P 2302 p 0301 code.
All spark plugs and coils are new. Engine still vibrates.
check compression. Check cylinder leak down. Then other stuff. Super Mario did a direct injected car awhile back and the injector seal was leaking. cylinder leak down showed it and smoke into cylinder revealed the cause.
🤘🏻
thanks for watching
Amazing video, you were thorough and paid so much attention to detail, defs deserve a subscribe and like, I think im having a similiar issues, I have the same engine in my a3 convertible, did a rebuild,, changed, spark plugs, coil packs injector, line boared the head, schemed the head, replaced rings and valves as well as bearings after cutting the krank as i hit a bearing knock, im gettting a misfire on cylinder 3 but when checking compression, it is low on 3 of the cylinders, the misfire appears mostly on idle and at low revs but when driving the car its fine on top, VCDS is kicking out a camshaft retard error but the variator solenoid is replaced as well, my mechanic is thinking the valve clearances could be incorrect as we did not adjust them considering the fact that we have done so much head work do you think this could cause such a result?
yeah I dont know.
hey dude !! excellent videos! but what about de turbo exauhst valve? and after that head did miss the codes? thaks a lot for that videos.
You mean the wastegate? I have a video for that.
You can take an old OEM guide and sent it out to a laboratory that does metal analyses. This will give you all the metals in the guides.
Very easy to do hardest part is having the instrument to run the test.
Yes, please provide me the name of that there laborotory.
@@CoolAirVw Going to ask around and let you know what I find
@@CoolAirVw Quick search: Anderson Materials Evaluation, Inc, Ph: (410) 559-9389, Let them know that you need the metals composition of the quides or explain to them what you are trying to do.
@@CoolAirVw Here is another lab, (866) 446-7609 APL Inc
I have a 2009.tiguan, issue is multiple miss fire P0300. Check engine on & EPC light on dash. Engine wont start, i smell gas, new coil and plugs 2 months ago, although found a crack on a coolant line, that run down in the front of the engine, i wondering if my heads are gone? Not sure if its worth fixing. Just bought the car for my sons 1st car and its not looking good.
should be able to diagnose a no start condition. check videos on FAST-TEC. Fuel, air, spark, spark timing, cam timing exhuast compression.
NICE DO A VIDEO SHOWING THE TESTING AFTER YOU ERASE THE CODES REPLACING THE HEAD
Ok.....????
It started with the 24v VR6 motor. Their gas motors have been shit since then. Dieselgate shows what the culture was like at VW engineering.
amen
I think a contributing factor is how hard that engines pushed maybe when it comes to turbos failing not everyone of these cars blows the turbo not everyone of these cars blows a timing chain at same mileage it’s just if an when
Yea. but wrong guides fail. As I know from multiple expensive experiences. Once also I worked on one that someone else put the wrong guides in.
Got ya I just got my Tiguan back from the shop they did walnut blasting at 120.000 km it was bad cylinder 3 injector was clogged dealer decided to do all new injectors it’s like whole different car now
@@wesleyhoare789cool
Ive changed the plugs and coil packs and my cars still popping an engine light for misfire not sure what to do ive already spent like 300 on this problem for it to keep happinging
correct diagnosis is important to not waste money changing parts that are not the cause of the problem. scan tool like vagcom can show you which cylinder is misfiring. If multiple cylinders are misfiring you have to look at why. Scan tool like vagcom can also show you fuel trims to help with multiple cylinder misfires. Here is one of my most recent videos where I used fuel trim to help with a diagnosis. czcams.com/video/K214of8Wzjg/video.html
Any ideas as to what the problem/solution might be?
get the right guides. Aftermarket needs to tool up..
well diagnosed ... but i agree with you not the best engine to be come across with issues...
yeah, your right.
Is the motor supposed to run with that ticking sound?
I'm pretty sure the engine in this video makes only normal noises.
Is the turbo working
yes.
Good info about the guides... but not good that you had to find out about it this way. =(
two other vehicles out there repaired the same way. Luckily one of them is mine.
@@CoolAirVw Yours also has the soft guides but hasn't failed yet or yous got a factory head?
what year is this one from?
part one shows 2012
You could install integrated engineering valve guides..
Interesting that you say that. At the time of this video couldn't get them. Plus I believe they are brass like the ones that failed. Let me know if they are not.
@@CoolAirVw at least they are used for abuse on ea888.3 engines and works flawlessly...maybe is the compound.
@@CoolAirVw i went to their site and they give interesting info about the install maybe you can go an check...i suggest change the valves for ferrea...stainless steel and inconel...maybe those 2 things could make your customers happy 👍🏼
@@eliseocortes0228 Same thing as before, they are "bronze" type guides. DO NOT USE "BRONZE" type guides for exhaust!
@@CoolAirVw so stainless steel or titanium guides?
After replacing the head was the issues resolved???…
did you watch the video?
@@CoolAirVw yes I did but I was wondering if there was any more issues after the replacement
@@herberthyosoylomejor2883 We have fixed all the ones that the Machine shop put the wrong guides in. Some of them we were forced to buy dealer heads $$$$$$$$$$$. But the last 2 we were able to get the right guides and now we offer them for sale.
@@CoolAirVw Cool 😎 and thank you for replying back. Question where is your mechanic shop?…
@@herberthyosoylomejor2883 Kansas City area of missouri. USA
How much is the dealer head?
Dont remember exactly but 800 plus.
Amazing how many problems. Do it all lol🍺
huh?
I need to get rid of my Tiguan
Maybe, but they drive nice. I just bought a 2018.
Cylinder 2 on mine 0 psi… at the shop they will have to open the motor.. if it’s a “wear n tear” issue, carmax will cover under extended warranty. We love the car but after this we getting rid of it.
Tdi engines or bust.
I drive one, my daughter drives one and my son will soon be driving one.
got 421k km on mine without any major repairs. 1.9 tdi vw touran. the biggest repair was probably gasket between top and block cause of excesive oil leak outside on block
@@ernestasb.8475 Any tdi is better than CCT 2.0L Tsi gas engine
This makes little sense, it needs to be a helluva leak to cause a misfire. This vehicle does not look old and this exhaust valve issue should not be happening.
It makes perfect sense. I would assume you haven't watched both videos. the exhaust guides were wiped out. The machine shop replaced a ferrous alloy exhaust guide with "brass" guides. They did this on 4 customer cars and one of my own. A competitors shop got the same treatment as well. Every single car they put those guides in came back with guides wiped out with random misfires (difficult to diag by the way).. Everyone was fixed under warranty. Last one on my car was finally put back together, only weeks ago.
@@CoolAirVw Plain brass was hardly a good choice for a valve guide.
@@CoolAirVw Thank you I was not aware the guides had been changed or why they were. No mention of the mileage. It strikes me this engine has lots of issues that makes it prone to misfires. A thorough investigation overall.
@@mrofnocnon Sorry I guess words matter. Me saying "brass" wasn't stating the the guides were pure brass, just that that was the "type" of guide they were. I certainly can't name the exact metallurgical content. Intakes are "brass" and exhaust are a "ferrous" alloy. Using "brass" ones was the mistake the machine shop made. This cost us severely as we had at least 5 cars on the road that had the repeat failure. Some of them we had to buy VW head to warranty. We have since found a supplier for ferrous guides for the exhaust.
@@CoolAirVw Well done.
that machinist knows of all these problems and 1 DIDN'T TELL YOU and 2. CONTINUES DOING IT SINCE HE JUST DID YOURS....Find a new machine shop!!!
Uh, no. The machinist did 7 or 8 heads before the first one failed. Then he, and the two or 3 shops that he did those heads for knew.
