Hi all! New to this forum and my daughter's '02 KJ, but not new to Jeep forums at all. I usually hang out in the WJ side of town...
Recently, I pulled a cracked head from the passenger side of my daughter's 02 KJ, 3.7L V6. I'm trying to replace it with a cylinder head from an '04 3.7L V6.
Is this even possible to do? I know the '04 engines got a little redesign from the '02 and '03s, but every thing I've researched said the cylinder heads themselves were the same. Is this true?
I can only install the cam sprocket and tone ring in the 10 o'clock position if my '02 engine is set to TDC. I'm using the cam from the '04 head but trying to install the sprocket, tone ring, and cam sensor from my '02.
If I advance the timing and idler sprocket and position the dot between 12 and 1 o'clock, then the V6 stamp on the cam will finally point at 12 o'clock, but that indicates that the engine will be out of time.
Any help is greatly appreciated and much needed and thank you in advance.
