I figured I would do a compression check on my new engine 89 TII...it only has 800 miles on it.

I used a regular compression checker that you would use on a piston, so this might not of been 100% accurate.. and I couldn't get it screwed in super tight..

But I saw (according to the gauge (93 psi rear) (93psi front)

Both pefectly the same. I've seen people post numbers as high as 120psi, but Im assuming thats an n/a. And I know tII's have lower compression rotors, correct?

So is 93 psi on a 89 TII good?

 

wait till you have 2-3000 miles. it'll go up.
