This is post head gasket change who done the headgasket change is unimportant what is are the #"s
Should be around 150-170 range,you may have blown head gasket between two cylinders,maybe bad piston rings,I had a blown head gasket between 3 and 4 cylinders,those 2 plugs were burnt.It was making a noise at 3 and 4 cylinders,the engine is a 2.4 nissan engine with carb.,had head gasket repaired,head machined and soon as it started,had to turn off,noise was still there,so we checked the cat out,and it came apart and was blocking the exhaust flow,so I removed cat and went with straight pipe from there,we have no smog test in this state,gas mileage got better and have more power.
Testimonial: "thanks for your help mr Thomas Perkins you are the best"
If the reading you posted are correct, you need the services of a qualified professional. ZERO (0) psi compression and THIRTY FIVE (35) psi compression are BAD.. it could easily indicate a leaking head gasket between these two cylinders.. OR...if the person did not reinstall the head with the engine in the proper time, the valves could have made contact with the piston and will cause this same situation... You are going to have to remove the head again and check for the gasket being installed incorrectly or the valves not being seated/bent/damaged..AGAIN = you need the services of a qualified professional
DO NOT use any sealing material.
