Intake Manifold
Got the intake manifold off, the gasket is very stuck to the manifold, anybody use a certain kind of gassket remover??
Also under that metal plate it looks like there is a big glob of something burnt (charcoal looking stuff) under the metal plate. Maybe oil or carbon burned and deposited under the metal plate???? Any ideas on the burnt stuff???

the burnt stuff is years and years of carbon and oil, the less often oil was changed and kept from gettiong black then the less of that there will be under the heat shiled under there, its not really gonna hurtn anytihng by leaving it, it can be gotten out of there if you bend the endges of it and use compressed air to blow it out and stick sometihng in there ot break it up. the middle port on each side of the intake(smallest) is where exhaust gasses travel throguh and under the intake manifold, is good for helpign to warm up engien quicker in cold climates, but if are in hot climate or never dirve it when really cold out then its good to plug that whole runner up.
gasket remover scraper deal undr 10 bucks at local store is a good sharp tool to clean off gasket, then clean surfaces with alcohol or vey similar to make new gaskets stick well, also use black RTV at all four coners of intake where the end seals and side gaskets all meet up good luck ------------------ Randy- Lincoln, IL randy@ccaonline.com 2177353230 *many GM parts bought, traded, or sold -am parting out: '81 Cutlass Supreme Brougham current fleet: -71 C-10 350/CH465/3.07- basketcase, #1 -90 Cavalier 2.2L sky blue, a driver -84 Z28 5.0L/700R4/3.73 daily driver -84 Firebird/SE 2.8L/T-5/3.73/engine bad, project #2 -82 purple Trans Am, project #3 *Paint is overrated* © RSS Enterprises 2000 |

I ditto what fast said about the egr passage, doesn't make alot of difference on the amount of build up because you will cover it up again anyway. as far as gasket removal goes, if a cast iron intake, i use roloc discs on an air die grinder, works great, but don't go too coarse or it will take too much metal from the intake and the heads. 3M makes gasket remover that can be sprayed on, allowed to sit and then scraped off, it eats gaskets pretty good, and then if a die grinder is not an option, I'd use some 400-600 grit emery cloth to clean up the sealing surfaces, makes them very clean and nice to reaseal.
