Ok car wont start...did a compression test and this is what i got
Cyl
1-145
2-110
3-155
4-120
5-60
6-85
7-140
8-170

What should the stock compression be? also what should this test tell me...I bought the car from a guy who said it have a bent rod??? Said there was a slight ticking in the front drivers side of the motor??

It told you to do a leakdown test, but if the guy already told it had a bent rod...it reaffirmed that.

Listen to what I was telling you.

Normally, if your compression ratiio had a cylinder or 2 off, maybe it's a head gasket. But they are all over the place. So I'm guessing you actually did the test right and the rod is shot and ....

YOU HAVE TO REBUILD IT!!!
