Nick1234 Posted May 6, 2006 Report Posted May 6, 2006 There is heavy amounts of coolant comming from under the alternator bracket right by the timing cover. I think Head gasket. Anything else to check. It does drip rather heavily. Also, somehow between all this i managed to somehow cause my tachometer to jump to 8500 and get stuck there. Im thinking cause the key was forward when the battery got disconnected. It is just a matter of taking apart the dash and putting the needle back at 0? Im actually more pissed about my tach than the other problem. Also its my 93 euro w/ the 3.1 Nick Quote
dbtk2 Posted May 7, 2006 Report Posted May 7, 2006 Lower intake gasket? Are there any heater hoses that run in that area? Does the car seem to still run okay (head gasket not leaking internally). My initial guess would be lower intake gasket, then head gasket(s) after that. Quote
1990lumina Posted May 7, 2006 Report Posted May 7, 2006 I've had thetach get stuck before (rev the engine and turn the key off beofre the needle comes back down......but restarting the engine always made the needle go back to normal... Quote
Nick1234 Posted May 7, 2006 Author Report Posted May 7, 2006 It runs fine and isn't over heating yet. No milky oil. No white smoke. No hoses in that area. I though if the lower intake gasket was leaking it would be oil. Quote
mfewtrail Posted May 7, 2006 Report Posted May 7, 2006 Nick, the lower intake gasket can leak coolant or oil depending on how the gasket fails. On my old 3.1, I had a lower intake gasket fail at 230,000 miles, it leaked coolant externally(no mixing with the oil) at the gasket on the driver's side. The part of the gasket on the passenger side was eat up pretty bad and about to fail too. Quote

I though if the lower intake gasket was leaking it would be oil. It depends on where the lower intake gasket is leaking. Haven't looked at a 3.1 LIM in a while now, but I'm pretty sure that coolant flows through the LIM and flows through the heads and the LIM gasket seals that and the air passages. Obviously it could leak oil as well due to the lifter valley being there and all, but it doesn't necessarily have to be oil. You have to pull the LIM to change the heads anyways, so if it looks like that may be the culprit when you have it torn down then replace it and put it back together without changing head gaskets first. Thats what I'd do. Quote
