[V6-12v] RE: Razzin-frazzin' oil leak!!!!!!!! (apowell )

[Doug Macy]

	A Powell wrote - ""Razzin'-frazzin oil leak" doesn't fully express my
feelings.

	The crankshaft front seal is definitely not leaking, nor is the oil pan
	gasket. The oil slick is visible only on the rear end of the block,
although
	it's dripping off the transmission and area behind the motor. After much
	contortioning and peering, I see from below that the highest signs of
	leakage reach juuuuust about to the height of the rear seals on the
	camshafts.

	I don't think it's the rear main. Why? The car has a manual transmission,
	and most of the time when a rear main leak occurs, it makes the clutch
slip.
	Also, there's more oil outside the bell housing than a rear main leak could
	account for - I think.

	I'm thinking that the offending seals are those at the back ends of the
	camshafts. However, BEFORE I start tackling that particular can of worms, I
	would welcome any thoughts about possible alternative sources of the leak,
	and any recommendations (do's/don'ts) about replacing the rear cam seals.

	I APPRECIATE ANY HELP."

FWIW I just had a similar leak on my 20V7a car, it turned out to be the oil
pump
gasket.

I must have molested it while removing the A/C. Little hole but high
pressure.

Driving the car blew all the oil down and to the rear... and no visible flow
from the leak at idle.

Have also had Oil Pressure sender "blow-out" on my other 7a car. Perhaps
find and
check both the "multi" and Temp senders if V6 cars have them. (again while
revving)

I notice in the ETKA that the 12V V6 has a different setup, but it might
be a similar problem. Check the front left side of block while revving the
engine???
Your oil pump should have a cylinder angled up into the front cover, behind
the cam belt.
