How can you tell the difference between a warped cylinder head and a blown head gasket? Without tearing it down?
2012 JKU, 120k miles. All stock. Good maintenance and vehicle history.
Runs fine. No rough idle. Overheats two or three needles width on long hills. Otherwise no overheating around town on relatively flat or short hills. Cab smells of strong coolant oder. Some coolant loss. No coolant in oil. Misfire codes. Also needs new oil pump, 02 sensor and 02 lead. And probably needs new rocker/lifters.
Trying to decide between repair and engine replacement. And its coming down to whether or not the heads are warped.
2012's were known for head warp. The manufacturer warranty was extended for this issue. But this vehicle is out of manufacturers 10yr warranty.
I assume the only real way to tell if the heads are warped is to tear it down. Which I also assume is at least a grand, right? Which would tip the scales towards engine replacement.
If the heads are not warped. When replacing a head gasket do you have to remove the oil pump or rocker/lifters? Trying to determine how much it would cost in labor to have those replaced while replacing a head gasket.
