Oil pressure update: 20 psi at idle, coolant temp 78 degrees Celsius. I believe this is within spec.

Okay, I will idle the vehicle for a few minutes with the OBD scanner plugged in so that I can monitor the coolant temp until it reaches operating temperature. I will idle it with the oil pressure tester in. Once it reaches operating temp, I will switch the car off and release the pressure from...

I did an oil pressure test, the results were as follows: 1) Cold Idle: 65 PSI (Workshop manual states: 4 PSI) 2) @3000 RPM: 80 PSI (Workshop manual states: 25-110 PSI) So it appears that there is high oil pressure issue on idle. Current Oil is Shell helix HX8 5W40. The car has a history...

Update: 1) I did a compression test, see results below. Cylinder 1 - 35 psi Cylinder 2 - 160 psi Cylinder 3 - 140 psi Cylinder 4 - 140 psi Cylinder 5 - 140 psi Cylinder 6 - 160 psi I am assuming that I have a blown headgasket given that there is at least some compression in cylinder 1 and not...

Apparently the best way to remove the sensor is to remove the cooling fan and then work your way in from the top of the engine bay. I don't have a lift and working from the floor could be a serious pain.

That crossed my mind when I was brainstorming possible causes. The oil pressure light did not go on when the engine first misfired. The guys at the shop performed an oil pressure test and told me that it was low, however the warning light was not on, it only illuminated after the car was parked...

It also has a faulty ignition switch actuator pin, I can get one off Rock Auto.

The tick is noticeable at idle and when revving the car in Park position. I have not driven the car on the road for a while, if I can recall correctly the sound disappears when I am coasting. I pulled the car out of the garage yesterday and I recorded the ticking sounds, I tried to attach the...

I got an 02 KJ with the 3.7 v6. It previously had a valve seat come loose and had a valve get stuck due to the loose valve seat. A refurbished head was installed a by a "reputable" engine rebuilding company. When the vehicle got back from the shop it had a ticking sound, the guys at the shop...
