Just got doing a compression test(cranking) and results are as follows, engine is warmed up prior to test.drivers side front to back.140--140--135--140
Passenger side,front to back....135--135--140--140
Reason I decided to do this was getting some smoke out the tail pipes when sitting for a long time. Hopeing its just the valve seals!!?? Seems to do this only once its warmed up.Any suggestions? Getting ready to do some things to it and want to make sure the bottom end is good. No knocks or rattles, oil pressure is perfect.
Plugs are super clean I might add.....

The compression numbers are good so on the face of it there's no significant ring/bore wear. If you're getting blue exhaust smoke at idle and under deceleration when the intake manifold vacuum is high, that would point to worn valve stem oil seals or valve guides. If you're getting blue smoke when the engine's under load, it's more likely the PCV valve mesh screen is clogged up. It's probably a good idea to check the PCV valve regardless even if it's just preventive maintenance.
 
THANKS fellas! Only time I can see the smoke is when I am sitting with the ac on for long periods of time. It doesnt even smoke when I first start it. Thats what has me puzzled.
At WOT there is ZERO smoke! Well, other than the tires screaming for mercy....:nono:
