Hey Guys,

Anyone remove pistons with the engine still in the truck? Seems simple, Remove heads, intake, and pan. Then push the pistons through. I'm wondering if anyone has run into the problem of too much of a ridge to get the pistons out.

Anyway, I may be in the neighborhood on replacing my rings, too much blow by it seems which leads to oil consumption. Can I get away with using standard rings to fix my problem or should get over-sized rings? Let's say .010". Will I need to bore the cylinders or can i get away with honing them and putting over-sized rings on?

Thanks!

 

The ridge depends on how many miles is on it. I took apart a motor with about 200k on it and it really didn't have that much of a ridge. As far as the rings you need to see/measure the cylinder wall and check for roundness. If it's worn(out of round) new rings wont seal so it will need to be machined. The amount depend on how worn it is.

 

Oil consumption? Have you checked your plenum yet?

 

Yes, the plenum was replaced. But I kinda have a feeling that the pan is warped. Might get a Hughes kit with the 1/4" pan.
