Hello all. Excited to be on a TJ specific forum.
I am replacing the head gasket on my 2002 Sahara. It has 130,000 and has run strong up until a traffic overheat and now a misfire in cyl. 1 w/ code. I changed plugs, O2 sensors and checked coil rail and injectors. I cleaned the engine, ran it a couple of days, and checked and noticed a seep leak on the engine case on passenger side cyl. 1. I also have the intermittent strong smell of gasoline and steaming coolant at various times under load.
I have rebuilt engines before, but never on a jeep, so I am asking this forum for help in anticipating any bumps in the road or other things I should be looking at while I have the engine opened. Also, not sure what the PO did, so I was wondering how to identify if this head is the infamous crack prone 0331 or if it has been replaced.
My plan is to purchase the Fel-Pro gasket kit, the head bolts, thermostat and the exhaust gaskets. I pulled the valve cover and injectors off and the rockers and springs look good.
Should I replace the fuel injectors since I'm doing this? Water pump? Lifters? What kinds of maintenance things should I do?
There should be a picture at the bottom of this post. Really appreciate all the help.!! Thanks for the advice and best wishes in your adventures!!
