Okay I just got my caddy back from the repair shop, I had a new Rad, Oil cooler lines and Oil Filter put in. The Rad and Oil cooler lines are not leaking at all. The oil filter however is being a pain in the ass, this is my second oil filter! The first one leaked none stop, This one leaks when the car is parked on a tilted surface and here's the kicker it leaks when the car is not running....:mad2:

So what can I do to fix this, is it because I'm using an NON-OEM part? Who else has had this problem? What oil filter do you recommend?

Never heard of oil filter leaking on an LT1. Make sure it does not come form somewhere else. It's a pretty bad leak.

I know its coming from the oil filter because the thing is soaked in oil from the top of it to the bottom. I'm wondering if its a gasket problem because if the car is parked on a tilted surface the oil seeps down the side of the oil filter

It's the oil cooler line adapter, the part between the filter and the block. Or, the lines that go into that adapter. Back to the shop.

Jay do you know how this can be repaired, The lines are brand new! How could it leak when the car is slightly elevated and not at all when parked on a level surface?

+ to what Jay said. Plus I would make sure there is no leak at radiator side tank connections. Just check for oil at the radiator support. If the shop screwed up teh adapter connectors, they could do the same with the radiator ends.

I checked the Rad connections all is fine there just have to deal with the stupid connections at the back but I have no idea why they would leak since they are brand new

Crossthreaded, or not tight enough are the most likely...

You paid for work. That work is defective. Take it back.

If I screw up my work, I look in the mirror. You have paid for the benefit of some sort of warranty.

The only (remote) other possibility is there is an old filter gasket stuck up in the adapter. However, you said the filter was replaced twice... and... if a pro shop left that gasket up there, I would seriously question their competency. Wouldn't be the first time a shop has screwed something up, though.

Just take it back to the shop. Don't be confrontational. Don't tell them what's wrong, other than "it's leaking oil from the area where the lines were replaced". Let them get it up in the air, cleaned, and diagnosed. When they tell you what's wrong, have them take you under the car and show you the problem.

O-ring was probably damaged..

I have never seen anything like that in these cars , we use OEM parts but this should be nothing to do with the brand name of the part , it's a defective job

Okay so here's an update, I talked with my mechanic about this situation and how its been an on going problem since last year. He told me that he could bypass the oil cooler lines He calls it the oil cooler delete. Has anyone done this to an LT1 Engine before? Will it cause damage to the engine? I'm just concerned as the engine was designed to have this particular system and just deleting it like that I don't know what the consequences would be

Total B.S.
He just replaced the oil cooler lines, why should they be deleted?
Also, if the leak is coming from the oil filter, what good will deleting the lines do?

Deleting them won't hurt the car, but if the lines and cooler are good, why bother? It's a common mod on astro/safari vans because the metal lines often leak, especially in the northeast, but they are mainly deleted because owners are too lazy to fab new metal lines or replace them with hoses (which is what my dad's safari has)

I know right? I just spoked with the mechanic in person and he just said that deleting the oil cooler lines would stop it from leaking, I told him that I paid 87 bucks for those lines why waste money on something that has to be deleted

Re: 1995 Cadillac Fleetwood Brougham Oil Filter Leak When Parked On Slanted Surface!?

It may not damage the engine but the oil will not be cooled. Sure, it probably won't get hot enough to need to be cooled but why delete a functioning system like that just because it's leaking? Why not fix it the right way. Sounds like the mechanic is lazy or doesn't want to make it right.

 

[jayoldschool]

You actually need a different adapter to delete the oil cooler lines on an LT1.

Your mechanic is lazy/incompetent.

 

[silverfox103]

"Jayoldschool" is correct, you paid for a job and you expect it done correctly. But as you may or may not know, those lines and adapter are notorious for leaking (on all LT1's). What many guys do, is scrap the adapter and lines and replace them with an oil filter adapter from an L99 engine (4.3) that are found on 94 to 96 Caprices. It eliminates the cooler lines. I've done that to 3 wagons and when my Fleetwood starts leaking they will be replaced.

If the adaptor is removed altogether, will an older Chevy oil filter work? The filters that have been used on Chevy small blocks since 1968?

Hey Skatter

I can only speak of what I know. If you replace the LT1 adapter that has the cooler lines, with a 94 to 96 Caprice L99 adapter you still can use the filter that was made for the adapter with the cooler lines. I've never cross referenced the filters if it will go back to 1968 and fit. It may, but something tells me it's physically a different size and may not work. I'm guessing "jayoldschool" should know.

Okay so the oil leak has been fixed, the problem was a split in the oil cooler line and it was dripping onto the oil filter making it look like the oil filter was leaking Thanks everyone who offered their opinions
