Sooooo.... Finished the head swap yesterday with the help of a friend.
Found that the tops of a couple of the cylinders were quite caked so we cleaned them right up.
Plus new-
- front/rear oxy sensors
- crank angle sensor
- oil filter
- Platinum spark plugs
Also did the welsh plugs while we were there, even though they weren't leaking. Kinda glad we did as they were original Mopar from 97 and had 235k under their belt with quite a bit of rust.
But...
Just as we were filling up new oil and coolant, saw that each and every one were leaking, without even starting it up and building pressure.
Even though I had read Go Jeeps write up, the factory plugs had no evidence of sealant - although in hindsight they would have been fitted with machinery at exact pressures and even force.
So, it's another week without the Jeep and another days labour to pull the box and get to the back of the head (plus do the one at the back of the block that we didn't do yesterday), along with the manifolds. Again.
Really sucks when you can smell freedom and then you're old mate Murphy pops in to say hi....
