I know what gasket dressing it. I also know what chemicals are used in various ones out there. A lot of the dressings have solvents or bases which aren't compatible with one or more of the chemicals they're going to be in frequent contact with. There are a lot of good dressings which don't ever vulcanize, that's nothing new; Hylomar started in the late 1800's. Their famous "Hylomar Blue" was initially developed with Rolls Royce for use in jet turbines.... Just because it's an awesome product which does a great job at something doesn't mean it's going to save a 7M from its owner.

As for using dressing in place of proper block preparation as recommended by the manufacturer of the MHG.... Anyone's free to try it. I don't care what you do to your car, just know what you may be setting yourself up for and don't bluntly recommend that novices follow your lead. They're going to screw up enough stuff on their own as it is. (not that you were directly suggesting this course of action, just venting)

Ideally, if you're going to use your own coating on a MLS you should disassemble it (drill the rivets and separate the layers.... You can't disassemble all types of MLS HG), strip any coating it has already in place, apply your dressing to each layer and then reassemble the gasket. This is only something you really would bother with if you're reusing a gasket or you're certain you know better than the HG manufacturer (warranties be damned).



Codster, the differences have been listed here MANY times. Please do some of you own research and if you have questions thereafter ask. I don't mind repeating myself if it's something difficult to find or not common but I can't imagine you'd have any trouble finding posts detailing the differences in just a couple minutes (I know I've posted in more than a few such threads here). At any rate the GTE has a different intake cam, thermostat neck and housing, drilled oil drain and feed ports for the turbo with tapped holes for the flange, oil squirters, low C/R pistons, higher pressure oil pump, higher capacity fuel pump, oil cooler,the block is driller for TWO knock sensors in different locations than the GE's one, larger mechanical fan and an auxiliary electrical fan in front of the radiator, and pretty much a completely different electrical setup including: CPS instead of distributor, paired coil packs vs the GE's single coil, larger injectors, different type of air flow meter.... blah, blah, blah.
