Low compression on passenger side

Good morning,

There is nothing you can add that will bring back compression.

There are three different chains that keep the engine in time. it is possible that the chains are worn or the guides are worn allowing the engine to go out of time.

The front cover will have to come off to verify all the settings for the chains to be sure they are correct. if all that is okay, then it is most likely a internal failure such as burned valve, worn piston rings.

I do not like this answer because the timing chains on the vehicle are okay and also both VVT valves have been done. but still only 90 and 95 lbs compression on one side.

Okay, sorry, I base my answers on your input. low compression on one side has timing in common.

I guess you removed the cover and verified but somebody missed something.

Happy New Year.

The problem is solved. I added one can of Engine Restore and vehicle smoked when cold for two days (cold start). I have been driving it for two days now and it is running great with no blue smoke at all and compression is definitely up.

Good, glad to hear it.

it will return at some point as that stuff is temporary at best. the issue is still active and just masked by this additive.
