'07 JK 3.8 Smoking

Noticed the other the day the coolant was low. Weird. This morning all of a sudden she is puffing the white smoke. 7rs and 99k miles, first major driveline failure. Soooo tempted to fix the head gasket with a V8.

Ordered gaskets. I have decided that if I tear it down and find any cracks in the heads, it's getting a V8.

Not sure why but I find myself quietly chanting "crack, crack, crack" :mrgreen: at my computer this morning. Hope it has them if you want them otherwise I hope it is an easy fix.

I ran across this and thought of you Clint. Not trying to talk you out of a V8 though…just an option.

Gasket kit came in yesterday. Got the Jeep and tool box positioned in the garage. My little propane heater was just not cutting it on this 27deg morning. Trying to get some motivation. So, in the meantime, looking at V8 swaps in the ol' internets. Shrek is right, LS is the way to go. I have come to a tough crossroads here. I think it is time to buy the wife a new car. The JK is at the point where stuff is going to start needing work. I think it's time to sell the CJ and move on to making the JK my main Jeep. Doubt I can get what the old JEEP is worth to me sentimentally, but it just doesn't fit in with my family anymore. I think I'm going to put gaskets in the 3.8 to get it driveable again, give the CJ a once over to fix some of the more glaring issues (don't think lap belts are a big selling feature nowadays), then use the sale money of the CJ to fund an LS swap into the JK.

This is the fitting going to the fuel rail. Has anyone worked on this style of high pressure fuel connector? Can't figure out the trick to get it undone. The releases are inside the connector:

Got the heads off this afternoon. Don't see any obvious evidence of a gap in the gasket between the cylinders. Driver's side pistons show a little more crud than pass side. Sending the heads in for a resurfacing; the valve train looks almost new. There is a carbon ridge at top of the cylinders, but it wipes off easily and no felt ridge underneath.
