    I need to post picture of the TriBond sealer. Yes it is an epoxy type of sealer. 99% success rate.

    This sealer started out it's life on the 2002 Trailblazer 4.2L inline 6. This had a 10 minute set time. it is now up to a 20 minute set time. On the 4.2L and other engines since GM has tools to align the parts that are being assembled.

    Example: The oil pan on the 4.2L. The block and the oil pan both bolt to the one piece bell-housing. If the oil pan was set on the block without the alignment tool it could be offset. I am talking a very small amount. I will use a large figure of 1mm in this example. The engine gets installed you tighten the bell-housing and it could either crack the bell-housing or fracture the sealer. Yes this stuff sets up that hard. The sealer beaks when you separate it.

    Example: On the 3.6L V6 GM has threaded jack bolt holes in the front cover to get the cover to break free of the block when you are removing it. It is almost impossible to get that cover to break free if you don't use the jack bolts.

    I know this is an old thread but, I just took my '98 N* apart (head gasket job). The "conversion Gasket" set from Fram contains seals for the block to case half. Do you use RTV and the seal? Also, there was no sealant on the rear main seal I removed. Why is it required for replacement? The center is pressed on the crankshaft and the OD rotates relative to the block so any sealant would be wiped off. Do the new Fram seals eliminate the need for sealant?

    Just some stuff i found

    the J 38817-A tool does NOT work on a 94 rear main as stated in this bulletin

    They dont sell the rtv in caulk gun tubes anymore due to most cases not needing that much, small tubes are $10 each at dealer

    The re-assembly procedure says to bolt down the oil scraper plate before the main bearing bolts, which is wrong cause the scraper goes onto the main studs and nuts hold the scraper in place.
