i just bought a used jdm motor n cylinder 3 has 150 dry cold test. the others have a little over 200 dry cold test. wet cold test on cylinder 3 show about 210. so im assuming the rings on 3 is bad. also i see a puddle of oil inside intake mani. do u think i can daily drive with bad ring in cylinder 3 for a year? motor is not in car yet.

 

Lemme get my crystal ball...

 

Shut up grumpy

 

Wipe the oil out and run it for a few days. then repeat the comp test.

 

Do a leakdown test to confirm results and diagnosis of bad rings.

 

Waiting for someone to answer this question.
Seriously? If it is jacked up either fix it or drive it until it goes. Those are your only two real options. This "what if" stuff doesn't get you anywhere.

 

if it was me id take the head off ,drop the sump off and fit new rings with big end bearings as if you carry on driving it you will damage the cat if 1 is fitted but obviously check the bores before spending out
