Ok I just recently rebuilt a 7MGTE using 7MGE pistons with a 1.4mm TMS headgasket and ARP head studs. It runs good and all but when I shut the car off overnight it leaves a small puddle of oil. I know how picky 7M's are when it comes to oil but I can't seem to pinpoint the leak (or actually around 10 small leaks). I've retightened the oil pan gasket and even covered the edge with silicone sealer with no results. How easy do the front and rear main seal blow? They are new but i'm running out of ideas as to what it could be.
Also when I shut off the car the overflow tank drips out coolant. It's never overheated and it's not boiling like a BHG just a small dripping for a few minutes after it's been shut off.
