Fix for head gasket OIL LEAK without removing head?

I thought I tackled my leak well with a valve cover gasket, sending unit fix, cam sensor, and of course the filter adapter. For sure, oil is leaking from between the head and block on the pass. side. Anyone have a good patch for this, short of pulling the head? If not I'll try to come up with my own, and post up. Thanks!

I know for a fact I would never put something called liquid glass in my motor.

OP: How bad is it leaking? If you go through the work of pulling the head, it would be worth it to upgrade to a stronger casting over the crack prone 0331.

Clean and degrease area THOROUGHLY with brake cleaner and toothbrush. Allow to dry. Apply thin layer of HIGH TEMPERATURE RTV to the area, working it into the groove of the joint between the head and the block, and allow to cure. Leak gone.

i personally wouldnt do it either i would just change the gasket. as i just recently did on my own, its not to much work, can be completed in an afternoon easy...

i was just offering something i have heard works, i have known people to do it in a pinch and have great success with it...

but the RTV option someone posted earlier seems like a good idea to try

Wasn't there a guy that had a thread up just yesterday about putting liquid glass in his coolant and now his XJ won't run? Seems like a smart idea to me.

I'm not sure that I would want to put anything with "glass" in the name in the oiling system... Reminds me of CFC engine death. I agree, try the RTV and if that doesn't work pull the head.

Agree. Either try Jeff's RTV idea or with the 0331 head being suspect for cracking anyways, pull it and replace it with one from Alabama Cylinder Head or Clearwater Cylinder Head.

If I were to take a factory 00-01 head OFF my XJ, because of the potential for cracking, I am NOT putting that same head back on the engine.

I know the 0331 head equipped engines are a little more complicated, but I pulled the head on a 258 once and it only took me like an hour to get it off. (never put it back on bc it was cracked). If you have the space and tools I'd just pull it and replace it with a real gasket. My dad always said, "If something's worth doing, its worth doing right." I'd prob try the RTV fix first, but if it doesn't work, just pull the head and be done with it.

I agree 100%. If you cannot fix this with the RTV suggestion I made, and decide to go the pull-the-head route, I wouldn't even THINK about putting that same head back on in those model years.

Toothbrush...Check



Mucho grease lightning and brake cleaner later...



Clean, I think



Decisions Decisions...The two on the left are out



First some high temp



Then 2 liberal applications of ultimate. 100 miles later, keeping my fingers crossed that this did it for now...

If the headgasket is bad wouldnt that mean coolant and oil are mixing? Don't know if RTV will fix that
