First post here so bear with me if you will.
My 90 accord with a 2.2 engine is a smoker with 211,000 miles. I just did a compression check on a cold engine and here are my results.
Cyl
#1 145
#2 143
#3 40
#4 160

I test each cylinder twice and came up with the same numbers.

Same results with a couple of squirts of oil on the #3 cylinder, the one I am most concerned with. The engine fouls the #3 plug within a week then I'm running on 3 cylinders with no more smoke.

What should I look at next? I cannot afford a full rebuild or replacement at this time but I may be able to get the head rebuilt.

Thanks in advance,
Bill

 

rings are shot in that cylinder

 

Even with the shot of oil you think it is rings? I'm hoping it's not a busted piston. How about valve guides?

Thanks,
