H2 piston slap

[cbz2500hd]

Being that the H2 Has vortec 6.0 has anyone heard of piston slap in one of these?

Just curious

I don't have a H2 but I do own a 2003 3500 cargo van with a 6.0.It is very quiet and does'nt burn any oil either.I'm happy with it's power,mileage and lack of oil burning like alot of the GM gassers do.I think it's the best truck small block ever made.

Hate to disappoint but my 6.0 has the piston slap and I have been given the 6 year 100,000 miles from GM for my piston slap.I hope yours does not have it, I thought I had cleared the piston slap problem but at 33,000 miles mine started.

 

SORRY

The knocking you hear in the H2 6.0 is the engine wanting to get out and move under the hood of a real truck.

The H2s will be like just the rest of the gassers, some will knock, some won't. I have been lucky to have a few quiet gassers.
