Oil pan gasket: who has done it and how?

[Sockethead]

Ok cool...one less special tool I need

Good idea to do the VAC shaft while you're in there, just that much more piece of mind if you rag on the car

Exactly and I run it pretty hard too.

The GSR 4 4bolt shaft is the ultimate oil pump shaft fix but probably overkill for a non track car:

How much is the vac shaft? Maybe do the oil pan Baffle as well?

Shaft/sprocket is 199.95. You need a press to install it or you can send the whole pump to them and they'll do it for another $100
baffle is $179.. It's all in their spece46 catalog

Bringing this shit back from the dead to see if you went through with the baffle and sprocket shaft install. I've been looking at them all morning and am trying to set aside a weekend to do this job because I did not like the sound of my engine after starving it of oil during autocross runs.

Edit: my b I see it now in your Tapatalk bio or signature or whatever shows up when I click your name. I'll try to find your build thread and dig through that.

I ended up going with the Achilles Motorsports oil pump. I liked their solution better.

Alright I read through your thread and dig around for more feedback on the baffle, but couldn't find shit for the M54 (mostly e36 guys). Did you ever do an autocross since installing the baffle?

I'm leaning towards the Achilles baffle and pump shaft as they appear to be the best options - just want to make sure that'll be enough to keep the oil at the sump during an autocross

I used the VAC baffle. I liked it because it had a couple one way “doors” in the bottom; oil can flow into the pickup tube but can’t flow out when taking sharp turns.
Whatever solution you use, you’ll have to have it welded in place. You also need to remove the OEM baffle plate. If I remember correctly, you just grind off the aluminum rivets holding it in place.

Yep! That's the way the Achilles baffle works too - same design - just seems to fit a little more consistently than the VAC.

I'm just trying to find anyone that has actually tested a baffle on an M54 - VAC/Achilles/whatever

I know your project kind of snowballed right into the supercharger and you just recently got your tune right with that, so I'm guessing you still haven't had a chance to put the baffle to the test
