My brother'* car. Has 123K. A rather severe oil leak coming from the passenger side of the car. Right in front of the oil filter on the passenger side there is what seems to be a minature oil resivoir. That thing is leaking. I'm not sure what it'* called or what it does. Maybe an oil cooler?

Anybody know what this is? It'* not on the Bonnevilles I know that for a fact. I would post on clubgp.....but you know how that goes....

there'* no res. however the motor mount catches and holdes all kinds of crap.
The oil pan gasket in VERY common to leak, even at 50k miles.

can you get a pic??

if it is the OP gasket, good luck, they are a mother to replace

Harder in a w-body opposed to a h=-body to change? I had the pans off several times in our various Bonnevilles. Never found them to be an issues.

That could very well be a mount. Never thought of that. As long as it'* not raining again tonight I'll try wrenching on it (I HATE working on wet, drippy cars).

The rest of the oil pan is bone dry. Maybe it'* just leaking from that side....
