Engine knocking, lifters and camshafts repaired?
This is the sound of coolant temperature and oil temperature above 90 degrees Celsius.Software translation is not very accurate.

Engine knocking, lifters and camshafts repaired?
still have a question. A Jeep engineer told me. Only damaged valve lifters need to be replaced. Such as bearing vibration or wear marks. If it's a design flaw does it always break the same position of the valve lifter?I know four are a group, he said to replace the problematic group, there is no...- fengfengfeng

Engine knocking, lifters and camshafts repaired?
Thank you for your reply. I currently have no misfire code. Through the stethoscope, it was found that the knocking sound on the driver's side cylinder was very loud. Tried fuel additives, nothing worked. A Jeep shop engineer thinks the camshaft is the most likely.My friend's truck was making a...- fengfengfeng

help help help Write suspension height. becomes plant mode
My final solution is to find a level ground. Then measure the distance from the hub to the edge of the baffle, and then use the factory value plus or minus the difference to achieve balance. I did this because the left and right heights of the vehicle are inconsistent after I input the data...- fengfengfeng

Engine knocking, lifters and camshafts repaired?
Almost 0w20 engine oil is used for the first tens of thousands of kilometers. After making noise, I tried 5w30 engine oil on the red line. It seems that the noise is a little lower than 20 engine oil, but it still exists- fengfengfeng

Engine knocking, lifters and camshafts repaired?
Brothers, my truck is six years old. From 70000 kilometers, the sound of knocking began. Now it has reached 130000 kilometers. The noise is getting louder. After replacing the exhaust bolt, the idling is quieter and the knocking sound is more prominent. The noise is a little loud before the oil...- fengfengfeng

help help help Write suspension height. becomes plant mode
Thank you brother, I have calibrated and balanced the body. The offset becomes a single digit. Auto-leveling was temporarily abandoned. It is enough to be able to drive normally. I don't have a backup. Because at first I just wanted to see the data, no changes were made. The height data I write...- fengfengfeng

help help help Write suspension height. becomes plant mode
When writing the suspension height, first select Spring Deflate to Reservoir (note: not Atmosphere), and the four airbags are fully deflated. Then write the height. Then clear the fault code. My suspension factory values are 77 79 76 73. Front left, front right, rear left, rear right. Note: When...- fengfengfeng

Issues with re-setting air suspension ride height
I mean. If your truck also doesn't automatically adjust the ride level. It is definitely not just a matter of setting the height value.- fengfengfeng

Issues with re-setting air suspension ride height
Brother, look at my topic, I suspect that there is a problem with the automatic adjustment, and now the air suspension does not move after parking. The values I entered are factory values and should not be skewed. Now the system status shows that automatic load detection is not enabled.- fengfengfeng
