Brand new setup, boosting 22psi on a 9:1. Separate catchcan for the back of the block, pcv all blocked off. Valve cover evacuated to another catchcan. We were leaking on the dyno, so when I got back, I ordered a new gasket and installed it to spec. Cleaned and prepped both surfaces, torqued by hand then finished with 1/4 turn. Use a dab of ultragrey on the corners and let the pan sit overnight before filling with oil.

Filled with oil last night, took it around the block without boosting and it was fine. Took it for another spin, but got into boost, come back, and oil was leaking again. I am using a Moroso pan and my tuner said just go back to a stock pan as he gave up trying to seal his own Moroso pan. It was also mentioned that I may have too much crankcase pressure. I don't get it, how much more do I need? Is my catchcan setup wrong? I just want to go enjoy my car that I spent the last 5 months building.

I have been running my moroso pan on both motors making over 500 using an autozone gasket and have had no issues.

I've searched and saw some folks using that same gasket, the Fel-Pro right? I might give that a try, is it not the same material as the OEM? Any different installation tactics for that?

underpressure02

yeah fel pro makes it. I just put it on and put some honda bond in each corner and bolted it down. Your pan is not warped is it?

Astig

I checked that too before the install, all the raised bumps were level. I even lightly sanded the surface of the mating surfaces so the gasket would have less of a chance to shift.

On a positive note, I'm getting changing the gasket down to a science... I feel like NASCAR!

Astig

Bought the FelPro, its a little more stiff than the OEM which may be good.

Hope this works, next step is getting an OEM pan if this doesn't work. Just a dab of ultragrey at the corners? I'm at the point where I want to just unload a whole tube of it, lol.

Astig

Tried a FelPro gasket, used a bead of silicone. To top it off, I sealed off the gap between the pan and block with ultra grey and let it sit 24hrs. Took it out again, no boost... no leaks. Go for a roundabout with some boost, come home. Drip Drip Drip...

I am about giving up on the Moroso Oil Pan! This is my 3rd oil pan gasket, and I'm frustrated as all hell.

you need to check the pan for warpage.

x1398126514652475 or hes just not torquing the bolts down enough.

just dont hand torque it, torque those bolts to 7 ft/lbs it will pinch the shii out of the gasket sealing it. I hand tightened my gaskets before and bolts were rattling loose and oil leaked out like crazy. On my new motor i torqued it to spec which is 7 ft/lbs and all my problems went away!

del_slow420

ill buy it if you want to sell it

The front vents on the valve cover don't help alot because there is a baffle right behind it. I had -12 on the front of mine and I kept blowing out the dipstick. I also have the two -10 ports on the back of the block. I added 2 -10 to the back of the valve cover and it has been fine every since.

agrn93ls

are you gonna auto x or anything???? is the pan necessary? if you wanna enjoy your car ditch the pan. at least for a while so you can enjoy that bad boy. have you located exactly where the leak starts? its probably more related to the oil sloshing than the boost especially if your on a fresh motor with all that breather set up. pinpoint the actual source put a lil silicone there.

I've had the worst luck with gaskets sealing on moroso pans. Stick an oem pan back on there. It works fine for my 850hp car, i'm sure it'll work fine for yours.

turbotypeR@SPEC

I have never had a problem with my moroso pan

RTW DC2R

oh damn I missed the part about hand tightening them with a 1/4 turn... there is no way that is tight enough. torque them to spec and you will be fine assuming the pan is straight.

tony1

The aluminum pans don't have the little dimples that the oem pan does to keep it from squeezing out between the pan and the block.

Gravy

when i was at my old job i had a bunch of customers in PR complaining about the seal with that pan. i talked to moroso a bunch of times about the situation, but nothing ever happened.

I went ahead and ordered a new OEM pan. Church says he pretty much gave up on sealing his own Moroso pan. This pan I have does have the dimples, and they are not warped when checked on a flat area.. Maybe I should clarify, I torque the bolts until I see the gasket start to squish slightly, and work in sequence from the middle out. On this last install, i even sealed the area around pan/block with silicone after it was torqued down. The leak is happening on the back side, directly above the drain plug. Won't leak during normal driving, only after I boost.

Oh well, this pan is going bye bye, the brand new GSR pan is on the way. Thanks for the input guys. Thanks Tony.

There isn't a ring or two from the old gasket on one of the studs is there? They can be easy to miss.

Astig

Nope, it even leaked from the virgin gasket on a brand new build.

I will take that old pan if you are going to throw it.

Astig

Well I'll get some of my money back on the pan, it has about 20 miles on it. lol
