Replace Piston Rings or Engine?
I own a Chevy S10, 2001
2.2L 4 cylinder
Had a problem months back with a Head
Gasket blowout. Got the set replaced and
Head shaved down. Now they engine
shakes violently and its because one or
more of the cylinders aren't pushing any
pressure through. (Confirmed by a Mech.)
The replacement cost for the piston rings
totals to about a grand, but the engine is
already old as is. 130k miles. Would it be
worth trying to replace the rings? If that will
even fix the problem? Or should i just place
a rebuilt in it? Prices range from 1500 -
1800. Got a good mechanic that will do the
job right and charges very well. Its just
sitting in my lot collecting dust at this point
because driving it is waaaay out of the
question. So im asking any pros. What
should i do? Other than replacing the engine
the shocks need to go too. But its been kept
very well for about 14 years now. Would be
a shame to see it go to waste. Any ideas?
Replacing just the rings may not solve the problem. To do the job right means boring the engine and installing new pistons and rings along with turning the crank and installing new bearings. Doing just the rings might keep it going for a while but if it is a keeper I would re-build it right or get a crate engine.
Long story short, like F.o.R. says at the end, get a rebuilt long block.
Rebuild it or install a rebuilt engine.
This surprised me! These little S-10 4 cylinder engines are usually indestructible. My '03 has 287,000 on the original engine. I'd either buy a rebuilt engine or a good used engine (that I can hear run). The engine you have has been apart once already and I don't believe a ring job will fix it. Also, you have to ask yourself what about the bearings, camshaft, timing chain, etc. With a rebuilt unit these should be new. With a used engine you'd be ok as well because you can hear it run before you buy it. HTH. -Jim
