Gasket question
Hey guys, I'm in the process of turbocharging my '98 TA and have to take off the timing cover to weld in a bung for an oil return line. The motor was completely forged and rebuilt about 1500 miles ago and I had a couple of questions.
1. Will I need to replace the timing cover gasket when I put cover back on? I put on a new one when the motor was rebuilt.
2. Will I need to replace the water pump gaskets? I know '98s have the crappy graphite ones but I upgraded to the steel and rubber ones when I put the pump on again a few months ago.
3. Does the front crank seal need to be replaced?
I don't mind having to replace any of these if I risk having leaks once everything goes back together, but money is money and I like to save it where I can! Thanks guys!

One more quick question... I put a new LS2 timing chain when the motor was rebuilt. Do you think this will be an okay chain for FI? I'm planning on going up in the 600-650rwhp range. Since I have the cover off this would be the perfect time to throw in a different chain if you guys think I should.
FWIW I'm just running a lil ol' LS6 Z06 cam. Look at my build thread if you need any more details on the motor.

^^wrong, the metal gaskets on the w/p and cover can be reused, just be careful not to damage the rubber portions and you will be fine, I would recommend replacing the crank seal however, you just cant always tell if you damaged the lip on disassembly and the balancer is enough of a PITA that i wouldn't want to have to redo it

With that cam I'm thinkin you should be alright, but I would consider asking in the FI section to make sure, those guys should have a better idea...cam wise you will be ok but I don't know if boost would add anymore stress??

I reused original gaskets w/60k on them, only put a little RTV where the corners of the cover, the oil pan and block all meet...three days of tuning after work, several 3rd gear highway pulls and 2500 mi later no leaks
