Oil Filter Housing Gasket

[NorthShoreChiMM]

Hey, since I’ve gotten the car I have always leaked oil. Couple drips every time I park it. Took it to my school with a lift and had guy look at it. We cleaned up the oil that was under the car with degreaser and brake clean. Fired up the car and held it at 2.5k, you could see a small seepage from the oil filter housing gasket. How hard of a job is this and is the gasket specific to marauders. Just want advice to those that have done it. Any precautions to take.Thanks appreciate it.

It's messy

You will drain all the coolant and oil , I used a razor blade to scrape off all the left over gasket

ive purchased them at rock auto, and purchased at Napa

Then you will bleed the coolant system

I think this may be happening to me also. Approximately a half teaspoon of oil every 1-2 days I’m guessing, just from leaving it parked that long and checking the ground, and only started in the past couple of weeks.

Standing on the drivers side of the engine and reaching down, I’ve felt where the OF meets the block, and it’s dry. The drip appears to be coming from about about 6” behind the OF (towards the rear of the car), and inboard of the filter mount a bit. Of course, it could be dripping from anywhere and running back to that point .

No idea if the housing gasket is the problem, but it’s the only thing I can think of.

I keep the underside of the car really clean, so even tho it’s a tiny drip so far, hopefully I can spot it.

It sounds like a PITA to fix; (the things we do for love, LOL!)

Follow up; I’m losing a few drips every night. Still not enough to show on the dipstick after a few weeks, but I have to deal with it. Definitely does not drip with the car hot / running. Not yet anyway.

Could it be that the (4?) bolts holding the housing have worked loose? Are there torque specs for those? Thought I’d try that first. 114k on the motor.

Also, dumb question: these bolts go through the water jacket? I never would have thought to drain the coolant first, so guess I would have been in for a surprise. Thanks.

P.S. Permatex on the backside of the new gasket, correct? Or is this meant to be a dry fit? Tnx.

It's the gasket. Replace it

The coolant passes through the housing to the block from the radiator. There is one big coolant passage and 2 oil passages, torque spec is 18 ft lbs but I just did 20. You will have to remove the sender unit, (makes it easier to access bolts), also use a gasket sealer, I used "the right stuff".

Thanks, appreciate the specific info. I have some Permatex aviation form a gasket stuff that should work. Not 100% on the sending unit, but I’ll figure it out. I know I did some rewiring there years ago when I installed the real OP gauge.

Thanks again.

It could be, I’ve seen them work loose and it might buy you some time, but it will eventually fail, I’ve done three so far.

Thanks. Three? Damn, in how many miles?

I think I’m going to put this down along with the COT O-ring leaks to all the pounding I did on the block to get the old WP out. Just too coincidental all these failures within a few hundred miles of that install it seems to me.

But maybe it was just time for these to fail. I don’t know about three though. After this one I expect to get another 100K before I have to do it again.

Three different marauders, one was about 130k, one was 160k, and one was 80k

Got it; wish I had that problem! Just one MM to worry about here, and right now it’s only a nit, but I can see it getting worse over time.
