Gasket Maker vs. OEM/Aftermarket Gaskets

Just generally curious what most folks here use for their gaskets on clutch covers and other engine covers. I personally used to buy Cometic gaskets and they worked great, but with the amount of times I would find myself taking off covers and going through gaskets, I turned to a red high temp RTV and never looked back. A bit of a mess if you're not careful, and the prep and wait time is increased, but I find that it generally seals just as well as an OEM/Cometic gasket and at a fraction of the cost.

I tend to get things right on the second attempt

Oem or cometic. Would want any of that other gunk to find its way into the engine.

Haven't had that issue so far. I think people tend to over-do it and that's where all the excess comes from. You're "supposed" to only hand-tighten after applying and wait an hour before torquing and then another 24 hours before filling with oil or fluid. Although I'm sure different brands are slightly different in cure time.

I'm interested in your take on RTV/gasket maker

Ive used Gasket Maker with no issues. I think it creates a better seal. Does a better job of filling in the tiniest of imperfections.

Like Brandon said: Dont squirt too much of it. Mate surfaces together and let it sit for an hour before torquing it all down.

If the OEM designed a part to be installed with a gasket..... I use a gasket. The right gasket.

When the shop manual says use a gasket and sealant, I do that.

The crushable nature of the gasket is what is intended to fill the imperfections in the mating surfaces.

Liquid gasket material may work; there's too much variability in that for it to sound like a good idea to me. As a short term, redneck band aid, sure...... Taking apart things glued together, then baked..... That can create more issues later.

I’m just a cheap bastard at the end of the day and if I dont have leaks I’m okay with using a razor blade to scrape away old material. I havent seen any leaks on my engine covers when I’ve done it but again, I use a high temp red RTV so it may just be the stuff I use

During high school, I had an auto mechanics class, for my final two years. In rural Texas. I saw enough poorly applied RTV mess things up in those two years to swear off the stuff, unless specifically called out for, in the manual. Bad stuff, like enough RTV squished into the rocker covers of a V-8 to inhibit valve train movement, or RTV gumming up the internal works of an oil pump.

One vote for OEM!

Gasket: my son had a VW 2.0 turbo and VW (German engineering) put most of the covers on with a hardening sealant. Much more difficult than RTV. Getting the covers off was very difficult. Wound up selling instead of fixing as engine was toast - my wife has told me NO MORE VWs! Finishing up replacing water pump on Honda Elite 110 - Honda uses a lot of O-rings, so much better than gaskets or RTV. Sealant can deal with bigger imperfections than gasket material and is flexible. Years ago (before most of you were born) my father taught me how to take a sheet of gasket material and a small machinist hammer and tap out a new gasket. He was trained as a B-17 mechanic during WWII.

My dad did the same with me..... Also started out as a B29 mechanic.... What a small world!
