I have developed a pretty server oil leak somewhere on the front side of the engine over the last year. This leak however does not show it self unless I'm driving under the right conditions. I have had the car off the ground idling and running the engine on some elevated RPMs and cannot get this leak to show itself. It seems to do most of its leaking at speeds of 45mph or higher heading down hill. I know this because the exhaust will burn off the oil leaving a trail of white smoke while cruising down hill and leaving oil all over the underside, rear bumper, the tappet side of the block, and who ever is unlucky enough to be behind me. After a 40 mile trip I will lose a quart of oil but sometimes I'll get back after a ride and not a drop of oil will be lost. This leak has me scratching my head.
About two years ago a pull the whole engine down to it's short block replacing all the seals. I'll list what I believe to be current status of all my engine gaskets.
-Head gasket (good)
-rocker cover (good)
-spin on oil filter assembly (good)
-tappet cover (surprisingly oil tight)
-sump (not so sure, those cork gaskets are tough to set on the main bearings)
-timing case gasket (I felt good when I put this on, I think its holding up)
-crank pully ( using a BHJ pully with reverse cut on a stock timing cover. I probably have a small leak here).
-water pump and t-stat housing (all good)
Currently I have the engine out sitting on a stand and ready to do this all again. But this time if there are parts to upgrade I'm willing to do it. I am aware of a few upgrades that Alpine Innovations offers and I plan doing them.
-AI sump pan kit
-AI timing case oil seal upgrade
-AI rocker and tappet cover gaskets
I'm not wanting park my alpine over a white rug, I just don't want to clean oil off the backside of my car all the time.
I'm interested in any other suggestions that anyone else would have.
Thanks,
