Question on rings and bearings 93 cherokee...Help
 

I just did the hed gasket and low pressure is a result of worn rings.
I should have done the wet test but I didnt so now I have to consider
whether or not to do rings. Compression on the first cylinder is 60
psi the other 5 are reading 120. Put some oil in the cylinder and the
reading jumped up to 120. Looks like the rings in the first cylinder
washed out from head gasket problem. The motor doesnt knock and runs
fine otherwise. It did sit for a year so Im wondering if maybe the
rings are frozen and I need to drive it for awhile ad free up the
rings in the first cylinder. My question concerns if I do the rings
should I replace them with standerd size or go up a size. I would be
doing the bearings also. If I do this fix I dont want the results I
got last time so Im hoping that somehow I can pull this off. One last
thing can I do this job with the motor in the car. Any tips on how I
can better do this job or fix this will be geatly appreciated

Sincerely

Mike

Your answer is. It depends on what the measurement of
the bore is and if you need to have the block milled or
simply deglazed.

Rings arn't guesswork.

You can not go to an oversize ring without going to an oversize piston,
which can not do without boring out the cylinder to the oversize and finish
honing to the specific piston that will be running in that cylinder. You
can re-ring with the engine in the vehicle, but it may be more time
consuming nd difficult to do it that way. Pick up a good manual on general
engine repair and read through it. You need to know more than anyone's
going to be able to write here to take on the job. Not difficult, but a
lot of things to do and check.
