No $$$... A new pan is like $300-400... used one is probably cheap. but AFAIK, you need to cut up your exhaust to get it out, and that'd be going beyond my mechanical skills (putting one back together, that it... welding and such). And the epoxy came reccomended by a Saab mechanic who had done it to his own car and drove it 5+ years without any problems... So far, so good... no leaks. And I do plan on replacing the pan... I just needed a cheap, quick fix. >Doubtful, although it can't be "good" for the car.

(cracked oil pan... thats where my leak was, nothing wrong with my dipstick) 3.50UKP?! thats simply outragous! (what's that like $10+USD?) Also I've noticed that I don't have an 'idiot' light on my dash indicating anything about oil. Either the bulb has burnt out, or its displayed on the EDU, which doesn't show anything due to a burntout backlight that I've been meaning to fix. Tomorrow I drive the car for its first real endurance trial after the incident. Wish me well, and I'll report back with the findings (turbo whine, lifter noise and what have you). Also... the MBC is no more (for now)... I almost threw it away, but I figured I'll save up for a new BPC (and possibly a rebuilt turbo, from the sounds of it), and set it up in an SMBC arangement (meaning you still have the BPC/APC controlling the boost, but the MBC keeps the wastegate shut until it reaches a certian level... or something, anyways its supposed to give you much faster spool-up while retaining all knock protection and stock pressure control). -Chris 1994 Saab 9000CSE Turbo 2001 Saab 9-3SE (parent's) 1994 Saab 900SE V6 (*RIP*) 1987 Saab 9000S (*RIP*)
