If I ever plan to rebuild my 5.7 Litre Chevrolet LS1 V8 engine I would upgrade the pistons & connecting rods to the full floating type of wrist pin setup since mine is a 2002 built engine,not 2004 onwards. I noticed that one of the cylinders (number 6) had a slight amount of scuffing on the cylinder wall which leads me to believe that is causing a slight amount of piston slap for a few seconds while the engine is cold during winter time,I noticed it nearly 5 years ago when I was replacing the hydraulic lifters. Once the oil gets up into the cylinders it goes away but I would consider replacing the pistons with at least new standard sized pistons if not 0.010" oversized pistons if necessary. Holden bored them out to that oversize in 1999 in the VT Commodore when some of them were assembled with a bad batch of pistons which led to premature wear of the Teflon coating of the piston skirts & excessive oil consumption. Holden had a technical service bulletin saying that any engine which drank more that 2.5 litres of oil within the 10,000 kilometres service interval qualified for the rebuild under warranty !
It is not home made, but it has no part number or name on it. It is quite old, so you probably won't be able to find an exact match, but you may find something similar if you search online.

Pressing the wrist pin out didn't seem to ruin the piston
I might have to do this to replace a bent connecting rod.
where do you get the jig that hold the rod?
Thanks. This was surprisingly helpful.
where did you get that punch for the wrist pin? only ones I can find are way too small and that one looks perfect for what I need do this
If they have two pin how to removed?
Thank you for this video
so its a stationary wrist pin?
Hey mr justin miller i just wanna ask if i can use a h beam rod on a press fitten piston is it possible?
Is the fixture you used home made or does it have a part number?
It is not home made, but it has no part number or name on it. It is quite old, so you probably won't be able to find an exact match, but you may find something similar if you search online.
