I plan to replace the pan gasket, I know some use RTV at some points on the gasket, where and why? 4.Does it take a puller to remove the crank timing gear? 5.What about reinstalling the timing cover and the seals for the w/p drive & opti I know some use a cover to protect the seal when going back on, is this right, where do yo find it? 4.I have new Bosch 3 injectors will they be ok? 5.What about a tune and who do you recommend? Thanks!
3. The pan gasket: Felpro OS34500R (one piece) Guys have had good luck both dry and with sealant in the corners (Felpro says dry). Get rid of the RTV and buy a tube of the Right Stuff, it blows away RTV performance wise and you'll need it for the intake anyway. Dabs of sealant in the corners help with the irregularities. Before you install the pan gasket, check for any of the timing cover gasket sticking out where the pan gasket goes, trim with a razor blade if necessary. I use just a little bit of TRS in the corners.
4. Timing cover: FelPro TCS45953 (gasket & seals) There's a KentMoore tool kit with the gear puller,installer and seal protector, you may be able to find one on ebay. I haven't tried to change the gears but it may be possible with another puller. Some guys have made a protector out of a Sharpie pen (this only works half the time,I tried it), the KM protector works perfectly.
Intake gasket: FelPro MS95580
The tune, talk to Mick (Mseven) here. I have a LT4 HotCam chip that I'd sell cheap. It's out of a 93 TransAm, auto trans and would need to be programed and checked out (I've never run it).
