Bad Engine?
 

All,

I'm looking for some advice on this. First, some history:

In December 2002, I bought and installed a remanufactured engine from
PowerPro Performance (the company with the long warranty) out of Missouri.
That engine had bad rings in #6 cylinder so it went back. I installed the
second engine, and made a bad claim due to the Mopar MPI + Clifford valve
combo (fixed thanks to Hesco) and sent it back. They shipped me a third
engine before I had analyzed the problem properly.

I installed the third engine in March of 2003, but it's been using about 3-4
quarts of oil between changes since I installed it. The compression test
passed (at least 160 on every cylinder) and mileage was acceptable (upper
teens), although I got better with a carb. It also seemed to run OK. Not
wanting to make another bad claim, I've been checking out everything else,
but to no avail. Finally, I took it to the Jeep dealership to run a
leakdown test: cylinder #4 has 33% leakdown (fail), and four others are at
about 22% (marginal). So I sent the third engine back. It had been in my
Jeep for about 15,000 miles.

PowerPro Performance's analysis of the problem was that my fuel mixture was
so bad that the fuel washed away the cylinder walls. I talked to Hesco
about this analysis, and they said that PowerPro's analysis didn't sound
right. In order for this problem to occur, I'd be getting about two miles
gallon, spewing black smoke, and choking on gas fumes. None of this was
true. Also, my catalytic converter is only about two years old, so I don't
think that could contribute to this problem.

Any opinion on either Hesco's or PowerPro's analysis? Preliminarily (I'm
supposed to hear from PowerPro again tomorrow), PowerPro says they'll
either ship back the bad engine (at my cost) or keep it as a core. Neither
option sounds good to me. Anyone else think of any other options?

Thanks.

Re: Bad Engine?
 

I think you may have messed up breaking your engine in, like the
first fifty miles are critical to break in the rings, forcing a dry wall
condition to burn in them in by lugging the engine in top gear and hard
accelerating from about thirty to sixty over and over and over:

Re: Bad Engine?
 

The description of engine number three reminds me of what happened with a
run of Chrysler Corporation engines in 1978. Good compression, poor oil
mileage, somebody forgot to stagger the ring gaps.

Re: Bad Engine?
 

Bill,

I followed their break-in procedure which, although not identical to the
ones on the web page you listed (e.g. accelerate to 55 MPH rather than 50
MPH, repeat 10 times rather than several times, etc...), are probably close
enough. Besides, their engine, their break-in procedure.

And even if I didn't, I don't understand how this could cause damage to the
cylinder walls.

Thanks.
