Re: Does it cause overheating or not???
If it was mine I would toss that block in the trash.
I believe all the wear and polished up parts was due to lack of
lubrication because of gas wash. Too much gas in the oil makes thin
oil. Your bearings were textbook for a gas wash or lack of lubrication,
so are the polished cylinders.
So in light of that, all the metal that wore away has to be somewhere
right? Think of all those little oil passages and how many of them are
blocked or partially blocked with the metal particles.
Then to make things even more interesting, you think it is a 0.040
overbore with 0.058 overbore pistons in it?????
I would be checking out the local wreckers for a low mileage used 4.0
out of a Cherokee or newer Wrangler. I got one with 40K on it for
$400.00 Canadian. The full long block. The thing runs beautiful, has
excellent compression, doesn't burn oil and goes like a scalded cat. It
will pull out fast up to 4500 rpm.
