Default did a compression test

well i did a compression test because i have had a noisy valve train and figured i would start some where because my rockers (harlan sharp 1.7's) are not adjustable and none of them are loose tell me what you think

driver side 1 120
3 150
5 150
7 150

passenger side 2 150
4 150
6 160
8 160

when i say compression ck i mean i hooked up a gague where the plug goes and turned the motor over

im going to do a leak down tomorrow and see if i find more

im and very confused way the #1 cylindar would be off compared to the rest.

Hard to say... You mean that cam doesnt make it noisy already? 237/245. Was that a custom grind?

what do you mean doesnt that cam make it noise already?? that confuses me. i would expect no valve train noise. it sound like a rocker is loose but none of them are

dont know if it was a custom grind i bought the car the way it is

Did you check your pushrod length when you installed your cam? They could be a little too long and keeping the valves off the seat on #1. You'd normally see it on all cylinders but they may be on the borderline.

edit: I just noticed you bought the car the way it is. The first thing I would check is pushrod length in that case.

The engine will sound something like a sewing machine normally.
