So i've had some excessive oil consumption lately. About a quart everythousand miles. I decided to do a compression test today and here were the results. BTW I have 101K miles.
Cylinder 1= 160-162
Cylinder 2= 155-157
Cylinder 3= 157-158
Cylinder 4= 142-145 without oil 150-151 with oil.
Cylinder 5= 150-152
Cylinder 6= 160-162
Cylinder 7= 150
Cylinder 8= 150
So, everything looked good to me except cylinder #4. Also when I pulled the #4 plug out it was covered in oil and fouled out. The ring must be worn. I had planned on a heads cam swap in the next few months or so but now i'm wondering if I should get a new shortblock instead. I'm not going to get anything crazy prolly a lightly used mustang or explorer shortblock. What would yall do in my situation? Keep the stock shortblock and do the heads cam or get a new one.
