did a dry compression test numbers came out 170 across all cylinders. Does this mean the motor is healthy ?

 

Your saying all four cylinders are at 170, I find that hard to believe, around 170 maybe, but all at exactly 170 no

Was this test done on a warm engine?
Was test done with more then a couple cranks of engine for each cylinder?
Was it done with TB at WOT?

If all the above is yes, then you have a healthy engine standard compression is 184, minimum is 135, but the main thing is no more then a 28psi difference between any cylinder, so with all of them at 170psi I would say it is healthy. 94

 

170 psi is well within spec for that engine.

Could still be healthy from the comp numbers but doesnt mean it dont consume oil ect but the numbers show a consistant even amount so the rings are good.
