Here are the result of my compression i did earlier tonight:

1st Compression Test without oil

C1 160
C2 150
C3 150
C4 159

2nd Compression Test w/oil

C1 175
C2 165
C3 160
C4 160

Are the numbers any good?

 

Hot engine? As in coolant gauge firmly in the middle and the car driven around a bit?

The H22A in my Accord right now pulled an even 155psi hot, no oil a month and a half ago. She still runs like a banshee but you will smell the oil burning, though that might be my valve seals. That's getting awfully close to the rebuild point, at least for your engine there, rings are cheap and you can hone the bore yourself.

Nah. I tested it while the engine was cold.



Did another compression test, this time while the engine was still warm. And here are the results:



Hot Test

All within 10% so good, C3 compression ring(s) are tired but still working.

Are you having a problem? 94

 

No, no problems at all. No CEL. Everything is running in good condition. Thanks for the input!
