please NEED ADVICE oil leak and Dizzy mount question


Durandal

Recommended Posts

so last week my car started smoking pretty bad from under the hood... I looked for where it was coming from and it seemed the smoke was just oil leaking on to the hot exhaust, I had known for a while there was a stud that needed some locktight as there would be a small amount of oil that would smoke in a little pool on the exhaust manifold itself between no. 3 and 4 cylinders. I figured the larger amount of smoke was just that getting worse, so finally got around to backing out the stud and put some blue locktight on it and tightened it.. ran the car for a few miles and checked it... that long standing leak was gone. but still there was lots and lots of smoke even though there was no more oil coming from that spot..

but under the car there was TONS of oil, (and the car leaked 3/4 of a quart in one night of about 30 miles driving.) from looking up under the car it seems that it may be dripping from the bottom of where the distributor mounts.

I see there is a vertical gasket between the head and the dizzy mount and the oil has to be coming from there or around there since there aren't alot of places at that corner that can drip on to the exhaust...

so I took the distributor out and the bolts (5 or so) that hold that mount to the head but I cant pull it off.. is there anything I cant see that would prevent me from pulling it off? or do any experts here know where there could be another leak to look for? this car (an automatic 74) is my daily driver so I really REALLY need to get this taken care of and due to lack of money I cant keep just feeding oil to the hungry beast..

please help!

where is the C.D batsignal when I need it?!?

Well since you pulled the dist housing, clean it up, new gasket, reinstall.

Once you have that done, the most likely place is gonna be your oil pressure sender. Does it still work? Ignition on, not started, you should get a red light on. VDO units do fail and will leak through the whole sender out the top where the spade connector is. It might even still register and leak like a sieve.

Another possible leak might be your dist O-Ring, it won't leak that badly, but check it too.

Otherwise your head studs can leak pretty badly if not tight. Older style heads have the exhaust stud threads bored and tapped through into the rocker area.

If it aint any of these easy fixes you may have head gasket issues at the block or valve cover.

Good luck and get yerself a manual

yeah c.d. is up early and i'm up late! can you see where the oil is hitting the manifold? mine did the same thing after a valve job. like c.d. said, check the oil pressure sender. mine was still working but was leaking quite a bit of oil.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
