i recently did my compression test and my numbers are 155, 160, 165, 170, (not in order) but i dont know if thats too low.. or my engine is not healthy or what... and i have over 120000 miles on my 95 gs. i love my car and its running good, it's just the compression worries me a little bit to get the hahn stage two. thanks

Those are marginal #'s. My original compression #'s were all around 175, worked good till my ring landing broke in #2. I had 98000 on the car at the time. Turbo was only on for like.....2 days.

so youre saying if i don't put turbo in for now and drive it good and take care of it as far as oil change and maintenance i should be okay right. thanks

what altitude are you at, that will effect compression numbers significantly, the 180-210 is for sea level anything other than that and you will get diff. numbers that could be just fine

Well what order do they go in? You may just have a HG issue depending how the numbers go in order. Do you have any signs of a leaking HG? Oil in the coolant, oil drips on your tranny, smoke from exhaust? I would also consider the altitude situation. Give us some more info and we may be able to answer. My car has 98,xxx miles on it and my comp after the HG change was 205 / 205 / 210 / 210. Miles mean nothing when it comes to this stuff, It's all about condition.

I edited to the wiki!

i dont know what the order is exactly but there is no leak at all, everything is fine. my engine bay is dry clean. and im in new mexico.. i dont know anything about the altitude over here.. maybe you can tell me. thanks
