Thank you the retaining pin was kicking my butt 🙏
Amazing ! We need a full DVD of a complete build from A to Z with the usuals tips of what do and not do, i m sure it can be done at his shop, i will pay for this dvd, i want to do the build by myself but no more time to go back to school or learn the mystakes by myself it will be too expensive ! You guys doing a great job ! Thanks for sharing !
JAY! PLEASEEEEEEEEE keep doing these. I will pay good money for a DVD on a full 2jz build. every little detail, every part, everything. The money spent can't compare to the knowledge i'd learn about engine building.
Amen!!!!
PRO AT WORK. WATCH N LEARN
In all of the technical videos I watch for diesel and gasoline engines, nobody checks pin to piston or pin to rod bushing. I appreciate you taking the time to show us, but why doesn’t anyone measure?
Make a full length DVD about stuff like this, really interesting.
I'd love to see a 2j block prep for being built. Hot tank, bore, hone, decking ( if needed ) balancing.
It could transfer nicely to a block build episode. Piston, crank, rod install, new bearings, oil squirter delete.
I'm building / parts whoring for my supra build so I always love 2j related material like this.
Keep up the great work!!
Great info! Love the videos! but just one thing to keep in mind. Orientation of the c clip is important at times.
Vertical gap either top or bottom.
The g-forces the clip experiences are on the vertical axis so with the gap to the left or right the clip has a chance to move thus a chance to weaken over time possibly causing issues.
These tech tips are awesome
good tips, keep them coming....
valves,springs,and cam stuff would be awesome!!! plus I'd deff buy a DVD if u made one!!!
You guys rock !
A series of videos for a full 2jz build from start to finish would be awesome
Another great one. I'm at work replacing a cracked piston in a Lancer Evo right now.
I'm surprised you don't have closed caption enabled! 😳 I'm deaf and had no idea what you are talking about.... bummer
Very useful
really looking forward to the heat range on the plugs talk from real street!....... something I'm looking to change on my car.
Piston alloy grades. What you need and why. Also ..What alloy fits what application ..And what you want certain grades for.i.e. 2618 vs 4032..longevity vs detonation resistance. Cast/Forged...Hypereutectic/Hypoeutectic... Street, Strip, Daily Driven. Naturally aspirated..Boost /NOS...Thanks...enjoying the videos...
Hell yeah, spark plug info. Should b helpful.
Is it common to get the small end bore of the rod to be bored out to fit the pins? How can you tell a floating rod vs pressed rod
I don't really have a request just wanted to say great vid
Does pin fitting require machining or can I just de-burr it with emery cloth?
Top of my rod is a little gouged and the pin is a little loose in the rod. Will the top end survive if the pin is a little loose in the rod when cold?
Hi, I'm rebuilding a gm 305 and I changed the piston but 2 of them rotates in the rod but they are a little bit hard. If I heat it about 40 degrees they aren't nothing hard. Is a problem? should I dismount it ?
Hi guys I agree with mat can we have a comprehensive motor rebuild video .... step 1 ...etc etc
Sup Jay i wanna know more about cam gears & valve springs my project car im building is a 1st gen neon 2.4 swap i nic named it sleeper beast lol
choosing wrist pin keepers, Spiro locks vs buttons?!
What happens if you leave the wrist pin that is loose like that on the piston?
Yeah looks loose as to me Im sure that would slap around hardout!
I would pay for a full a DVD also
Wow this is 4 yrs old but im gonna ask anyway, ive heard the retention clips have to be inserted with the gap either toward the top of the piston or the bottom on a boxer engine...and that any other way will cause them to fail. Is there any truth to that?
Yes. At high RPM, sideways facing clips can deform from the G force at TDC and BDC, causing them to pop out of the groove. Mayhem ensues after that.
pretty inaccurate video......you're NOT supposed to re-use piston clips...also, NOT all engines are designed so the Pins slide threw effortlessly....many engines have Tight clearances in that area, from the factory.
Your opinion might have more weight if you knew how to spell _through_
I just through up
Bad bad bad advise.
You can't feel machine tolerances.
A real engine builder will measure and record all dimensions. A micrometer and a cheap snap gauge is all you need.
Shake my head.
