    Re: 98 ETC Head Gasket project started today...

    new oil manifold, rear main seal and rtv (permatex right stuff I believe is the name of it) for oil pan and half case. I would do it since you are this far in. Main bolts are reuseable, rods are not. You are also gonna need the install tool for the rear main seal.
    Hope this helps Joe

    So that's it? Not so bad I guess. Interesting that you just permatex the oil pan. Actually now that you say that, I do seem to remember reading it somewhere. What other seals should I address? I guess the Rear main seal is the most troublesome since you need the tool.

    Might as well inspect the crank, and main bearings will you have the engine inverted.

    I will certainly be able to get a good look. But based on the excellent condition of the cams, I am expecting (and very much hoping) that everything in the bottom end will look as nice.

    Joe, I think I came across that TSB in my reading... Wasn't it AJ who posted it?

    We replace the oil manifold (it has seals embedded in it) and use permatex ultra grey as well as some anaerobic sealer

    we also replace the oil level switch and the oil pressure switch along with the oil filter housing to block seals (big fat orings)

    we also replace the rear main seal and the front cover gasket

    You are correct, Faded crest. Here is the link again in case you need it.

    Can you substitute Permatex right-stuff for the GM sealant?

    Here are some shots of getting the old rear seal out. Those are self-drilling sheet metal screws that are driven into the old seal, and then pulled out with the bolt screwed into the crank.

    Cheers,
    Steve

    Re: 98 ETC Head Gasket project started today...

    Steve - nice pics...what is that - a seal remover tool for the new design seal? Where did you get it? I didn't need that on my '97, as I had the old lip style seal; I drilled a small hole in the metal part of the seal, then used my dent puller...that was the correct procedure per the GM manual at the time, I believe. I'm sure I could have just dug around with a screwdriver and pried the old seal off, but didn't want to chance gouging the block cavity or crankshaft output flange.

    Any update on the "wobbly inserts" dilemma?

    Re: 98 ETC Head Gasket project started today...

    What is the best way to remove carbon buildup from the tops of the pistons?

    ----------

    This is what I dug out of the water jackets... Stop leak granules. For anybody who thinks this stuff will help a leaky head gasket or stripped bolts, I have bad news for you... It was all gathered at the bottom of the #1 and #8 cylinder jackets. None of it was attached to the head gaskets or the head bolts.
