reply for more info:
More information needed.
1. fresh water or salt water - Brackish
2. did water get into cabin - no water in cabin, but Jeep stalled because he moved in reverse to get out of the way of an oncoming UPS truck - Also, depth of the water was right at the door sill. When I went to get him, he was able to move the jeep out of the water to higher ground, but I was not able to cross the area because the water was higher.
3. you say your son "stalled it" - Jeep would not normally stall in water that shallow so ??? especially since exhaust pipe outlet is higher than bottom of the doors - I am thinking backing up the water went up the tailpipe
4. did it sit in water long and if so did the water get higher. - It only sat a few minutes. He went to his friend's house and got the starting fluid
5. have you checked all the fluids (oil, ATF, transfer case, differential) for water. - Engine oil yes, transfer case and diff no. ATF no but no "water rings" on the dipstick.
If I was to guess water got into the exhaust system and "fried" the catalytic converter guts. - Thats a good thing...
Glow plug fault code translates to bad GP which if OEM ceramic is likely to result in a split GP tip and possible engine damage. FYI glow plugs always cycle on start up even if ambient is over 100F per FSM. - I figured that.
A small amount of white smoke before the engine starts to warm up is not abnormal. Mine does not do it but my son's 06 does.
Oh no, lots of smoke until engine warm. Like I said, no power loss, she does sound "louder" more like a tractor, but that has been for a while.
No coolant loss, no oil in coolant, oil level consistent - It doesn't go up or down... other than blowing off almost a quart after an oil change.
127K on the clock confirmed by my son.
I thought water had gotten in the intake that would have stalled the Jeep, but.... white smoke continues after 3 months.
Yes, yes, I know.... but son works a lot and it's hard for me to get my hands on the Jeep.
Symptoms of a cracked head would be, loss of coolant, blue smoke, engine oil loss.... Why would symptom go away after warm up? Perhaps, the "crack" isn't complete, so when the engine warms the crack closes? 'eh... I dunno but again, I rely on the group...
Fuel filter prob due to be changed. it does have the gen 2 fuel head, replaced at last filter change.
