Re: Does it cause overheating or not???
 

That Bull. I don't know where you got your info, but if they make as a
stocking item a .060 piston for that engine and the manufacturer has
determined it's acceptable the chances of "blowing out a cyl" are 0. Come
to think of it, in 30 some years making my living at and playing with
engines I have never seen a thin cyl wall "blow out". As to running hotter,
if the cooling system is working properly you will never see any difference
in operating temp and there is no need for concern on anything. The cooling
system is over designed to accommodate heavy loads on hot days and still
leave some reserve capacity to cool. You might move slightly into that
reserve capacity, but I doubt even that.

Re: Does it cause overheating or not???
 

Thanks guys,

That's why I come here.... for a reality check. I can understand one of
the sources of this mis-information (a engine remanufacturer in LA
http://www.wla-engine.com/ ) who's trying to project quality or higher
standards I guess. Who knows. Marketing mis-information.

But the other sources were life time mechanics.


Thanks,

Bill

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.
