Gents,

Looking to buy a '94 Brougham. The front of the LT1 engine is covered in black crud at the bottom fromt. The centre steering rod, p/s ram, trans lines coming out of the rigt hand side lower front block area and left hand side lower front are all covered. Suspect an oil leak.The ower says it doesn't drip but it must do with all this over the front. Here's a pic, can anybody point me straight on what is happening please?

Many thanks
Nick

Oil cooler and trans cooler line leaks have been a common issue on Cadillacs since the 80's. Nothing new there. Very simple to fix. Just be VERY careful when removing/installing the lines on the radiator. The reason for this is the cooler inside can be fractured very easily if you don't hold the fitting on the radiator while spinning the fitting on the lines. Even slight rotation "can" cause the internal cooler to crack. The fallout from improperly done line changes is oil in the coolant.

Were you taking pics under my hood? We have the exact same problem. Dont worry about it. I've added a quart of oil in the past 6 months, 2,000 miles, really not that bad, the car is driven almost daily.

I found another line in the back, that is steel, it looks moist like something is seeping out of it. Im sure its either the oil cooler lines, OR the tranny cooler lines.

Bad thing about a tranny oil leak, I read on an Impala SS forums, someone lost a quart of tranny fluid I think it was, and it kinda killed a couple things in the tranny.

Its perfectly normal, just look at mine. :histeric:

Guys,

Thanks for the post. This reassures me! Is it going to drip oil on the pavement though?

best regards

Nick:

The mess on the lines is from them leaking. I've had my factory trans. lines to the radiator changed two times from leaking (over the course of 120K miles).

Wasn't sure if your were talking about the flakey covering on the other items. That almost looks like a paint covering that has pealed off from the engine heat.

Scurling,

Thanks - I was talking about the mess all over the lines. I was wanting to know what type of leak it was - engine oil/ trans oil/ p/s oil? and if it was a serious fix.

Thanks
Nick

Had our oil lines replaced as well, 1996 Cadillac Fleetwood Hearse.

My guess it would be the pesky water pump shaft seal on the timing chain cover that is the culprit

Anyone now where I can get a replacement part for the GM oil filter adapter? GM Part No.: 12556201.

Thank you.
