Should I? Shouldnt I?

So I was pulling my Pistons out of my block today because I thought my rings were bad.

I discoverd that my pistons look BRAND SPANKIN NEW from the Rings Down. they still have that nice shiney piston look. how ever the rods look like they are OEM. I don't think my pistons have more then 10k on them. the previous owner didn't say anything about the new pistons, and I don't think he knew about em either. so I checked the rings in the other 3 pistons by dumping water on them, and seeing if it drained or not.

It did drain but very slowly, it was just a small drip drip.

So my question is. should I still go ahead and replace my rings? If the pistons are that new, then the rings should be too shouldn't they?

(FYI i am for sure replacing my bearings because they are in horrible shape.)

What was your compression before? Did it run well?
If you do replace your rings you will need to hone the cylinders for them to seat.

last time i did a compression test was 500 miles after I had rebuilt my head. (that includes head gasket!) it came up 132 127 143 137

Its a 1.8L 4G37 btw which I think I just answered my question because. the Standard limit for a compression test is 185, and the service limit is 131 (according to my Repair Manual) but then again.

These are the symptoms I had the last few times I drove it.

*Oil pressure Guage reading very low\zero
*Dead Cylinders (sometimes 1 was dead, others times 2 or 3 were dead
*Severe Smoking Blueish\White
*Lack of power
*Poor Mid and Top End. (rare it would go higher then 4.5K RPM)


and yeah i know i need to hone them. i planned on honeing them anyways. there was a like a crystallized Carbon build up around the top of each cylinder.
