    I was told by more of a senior member that the head gaskets don't go on these any truth what im seeing is steam from the cats at times and user error like a grommet missing ??

    kind of a thin silicon grommet set al dente for torque setting my 1/2 inch torque wrench from harbor is overkill any suggestions or links would be cool …..just happened to be doing a brake booster lucky for me that I can see day light there and opened my plug caps and pulled a plug to find oil …

    "steam" and "white smoke" aren't exactly visually different. If it smells like burning tires, it's oil burning. Coolant smells sweet

    The plug well rings fall out very easily during installation

    The torque needed is in in-lbs, not ft-lbs. The wrench I have for this is 1/4" drive. Hell, my wheels only require a 3/8" torque wrench to get 100ft-lbs. There is also a sequence that you should follow to tighten it

    Correct, head gasket failures are extraordinarily rare on these cars. It's much more likely you either dripped oil onto the cats and need to burn it off over a few hours or there's an active leak. Cleaning the area and inspecting later for fresh oil should help pin it down.

    I used fel-pro. One fell out the first time. The second time, I was just more careful. I pressed them in firmly and then flipped the cover slowly. Once in place, I lifted a tiny bit to feel under and make sure they were still in place

    there is a small ridge that is on the surface of the gromets in all the sets the ridge is flattened out and the grommets are getting hard like all the grommets were in I just found a loose one I was worried now im worried again cause even though new there getting hard and flattened out // these oils get newer every time some may penetrate this is a 5 /30 don't know well hell they can back a cake with good silicone these days what are they messing with real techie quest dam I might have to pay 1oo to ford just to ask … good cop bad cop duh on a thin or slippery the old ones show signs of some paintings of grey maybe the guy before me had inspiration

    Is this a V8? I seem to remember the ridge of the well rings going up into the valve cover to hold them in place. Where is the "paint"? The ridged tabs on the main gasket requires a dab of RTV to seal against the timing cover seam. Please throw some punctuation in there. I don't know which "grommets" you're talking about. The plug well rings you just installed?

    original plug tube gaskets had some grey on them but done very neatly I can peel it off ...the new set leaked I used some grey a bead on the bottom of the head maybe it was too much ...what about in the grooves altogether think I can use some black this time from a fresh tube and do the grooves then put in the gaskets in wait 15 then smash it on ….he ha felpro has a set ill probably just order there is also apex a few bucks more
