  • Piston slap

The only mod I would ever do to a 3100 powered wbody is put in a 3800.
Ummmmm... Duh!?!? Been there and done all that noise! As a matter of fact, my 3100 is still on the road, approaching 270k after the recent disappearance of the front cover gasket which went poof (like magic disappeared) and a pool of coolant followed. It's in my sons hands now and he's learning the joy of owning a Pontiac!

So, you think I am unaware? Point is, once the attempt would've been made the realization wold take hold as to the fruitless effort! Can't even find Pacesetter Headers (70-1207) for the 3100 anymore, lol...
