captdistraction said:I haven't torn down the block yet, but there are the following issues that make me think I'm not getting good ring seal:
1: smoke on decel
2: oil always smells of fuel
3: the breather setup would always smoke under idle or when I lift (could see it leave the vents on the tiger hood at slow speeds or at a stop). So much so that I put the factory PCV system back in.
I'll know soon on the tear down. Still going to see what's on the table with MMR before I make any decisions, though I should have those head castings in hands soon.
Number 3 indicates piston ring "blow-by" where compression stroke blows by the rings into the crankcase. I take it the heads are not removed and you have yet to see the condition of the cylinder walls?
Also, crack open your oil filter and look at the pleats for the amount of debris, and check with your magnet for iron particles v. aluminum particles. Then inspect the oil pick up screen for particles. If there was oil starvation, then rod end bearings are quick to go.
You will have to go thru the entire oiling system to ensure you don't re-contaminate your new rebuild. You should also be discussing the need for a complete tear down and inspection with your engine shop and see what they say.
Good luck and keep us posted.
