Hello, all apologies for posting this in the wrong place but I have quite a few questions for diagnoses on a 4.6 and much needed advice for my learning experience.
95' mark viii teksid aluminum block with stock b head
I have questions on what should I expect from the few results I got from basic compression (cold engine on a stand with oil) and depending how severe if I should need certain machining
Cylinder compression:
1) 165 dry -
2) 170 dry-
3) 152 dry-180 wet
4) 140 dry-160 wet (assuming a valve related issue)
5) 155 dry-180 wet
6) 172 dry-
7) 180 dry-
8) 162 dry-
battery voltage 12.78v-12.64v
My access to Ford specifications allowed a 70% from Max of 180 psi - 135 psi min
I did not finish the wet test on the remaining cylinders assuming they weren't too bad
excuse my lack of experience.
