Nice bro..... thanks..almost 10 yrs i fot the correct ppsesion but when i see your vedio..now i remember..god blz
Glad it helped. Good luck on build.
thank you im gapping my rings and your info helped me out
Glad it helped.
Thanks for sharing rod to piston install .I been looking all day on the web for l.s. 3 now I know thanks. I gonna put my l q 9 altogether with confidence.peace gear head.lol.
Glad it helped Man. It's easy to get lost in the forums and still not come up with a definite answer lol.
I just wanted to add that your filming was very clear not like many others that don't show wat their doing or they block the camera with hands or body .thanks again keep ur videos thanks coming.
Thanks Man. I'm still a beginner but ea video is getting better.
@@Brandon-LSX It sure is..and the absolute worst advice and info is found in the forums. I have a buddy who swears by forum...even though he keeps blowing up gen 1 small blocks. I've tried to convince him to jump into the new millenium and build an LS and then I can probably answer any question he may have...but nope..apparently my track record of zero failures is unappealing. lol
Ya its definitely a mixed bag on the forums. I've had some amazing pointers and some not so amazing but believable pointers lol.
Hello from Germany ! I am allways install the cam shaft first ! :-)
you should start a forum thread on thirdgen.org and link your videos there might help get some views. good video dood
I no longer feel alone for having and using fishing pliers in my tool box lol
The chamfered side of the rod goes to the crank fillet so 1 3 5 7 the dimple faces forward and 2 4 6 8 the dimple faces back the back of the I always was told.
This is the only way the spec sheet said so that's how I assembled it. Are you referring to LS engines or small block chevys?
@@Brandon-LSX LS engine that’s the way the machine shop installed them and said that’s how there installed maybe machine shop got it wrong
@@jimmycallaby1133 Some people say it doesn't matter some do. I've only ever heard of them all facing one way.
Jimmy is correct. The Rod surfaces are supposed to face eachother, when they share the same journal on the crankshaft.
@Brandon-LSX on the ls motors, they don't have a large fillet radius. So rod orientation isn't a issue. On aftermarket rods and pistons you need to make sure the chamfer is facing the radius. If not they will interfere.
hey iroc, i was wondering where those pistons come from i just bought a set of used 4th gen rods with those pistons on them and i cant find where they came from !
I believe these pistons were out of a L92 2007 escalade 6.2l.
That means , every connecting rod have a mark to find out the direction?
Yes
Could you post where you got those spec sheets?
Got it off All Data.
How much does each piston weigh? If you don’t know this, then you are setting your engine up incorrectly and its pretty much guaranteed to be unbalanced. There’s alot more to proper assembly than you can get from a guide or from reading a book. I have assembled hundreds of(if not, over 1000) engines and have learned the hard way more times than I’d like to admit. The most crucial focal point on any LS engine oiling. Biggest effect on even oil distribution is the rod bearing and main bearing clearances. Installing the cam bearings correctly too.. honing and polishing the journals is a must. And then plasti-gage the clearances within spec... people recommend hi pressure oil pumps as a bandaid for sloppy engine builds. Take your time and do it right the first time... And You won’t end up doing the same thing again next winter.
I agree balance is the most important aspect of a long lasting engine. I can't remember the weight off the top of my head. I had the machine shop balance the rotating assembly for me.
What brand of piston

To the ones who say one bank goes one way and one goes the opposite - I just tore down my 2007 - gen 4 engine with 365000 miles on it. I have this Tahoe since new - so it has never been tore down. EVERY dimple is facing rear! There is zero wear on any bearing, and there is .015 side clearance. And I've tore down 7 more gen 4 LS engines (cannot say if they were never tore down) but EVERY one had the dimple facing rear. So, for 1, 365000 mile LS, and 7 more LS's, the factory installed the rods wrong? UM, NO. When a stock crank is used, the dimple can be used for orientation. When a crank with a radiused fillet is used - you should be using proper rods with proper chamfers...
