Turbo and Supercharger discussion

#122456 Ok, so I boosted my car about a week or so ago and everything has been running fantastic and all except for this one little problem, after a few days of driving it, it started to leak a little oil, I mean like 4-5 drips when I park it and come back a few hours later from the hole where the return fitting is in the oil pan, my question is, is it leaking from there possible because my oil is too high in my pan and it's kinda over full (my oil goes about 1/4 inch above the 2nd mark on the dipstick). or is it really leaking because the oil pan is pressurized and it's pushing oil out? I had it sealed up, but I think it's leaking through it a bit now? Also, any other suggestions to fix this hopefully without having to drop the oil pan again =/


Sorry for the wall of text, and thanks for the responses :thumb:

#122462 how did you install the return? Please tell me you didn't use JB weld.

If it was properly welded then it should not leak. If you used threaded fittings, did you use thread sealer?

Well, It was a 45 degree angle -8an fitting with a nut on the other side, and i did jb weld it :( as well as tighten up the nut on the other side, but it still leaks a little bit, do you think it would not leak if the oil was down more towards the top mark? Or do you have any other suggestions?

#122482 well, you could try putting less oil in the motor first. But even if that 1/4" makes enough difference in the oil level to be below the return tube, it is still going to slosh around while you're driving. Or what about when you park on a hill?
Taking the pan off sucks, but I think it's best to do it the right way now instead of leaking oil for a while and hoping it doesn't get worse.

I'm with him all for doing it right and everything and I've tried to do it all right so far, but I just really don't wanna pull the pan again, I've had it out 3 times already, now this happens :shock: not to mention any time I have to pull it I have to pull my down pipe too, which is the biggest issue since its impossible to get on yourself, and it's still retarded hard to get on with 2 people.

Also, is the oil pan pressurized, or is the oil just sloshing/leaking through it, or is it being pushed through by some pressure?


Thanks :thumb: :thumb:

#122607 There should not be any pressure forcing it through, assuming your engine is in good condition. a clogged pvc system or bad rings could cause excess pressure.

But after the oil leaves the turbo, gravity is what makes it move to the pan - the reason a straight vertical as possible oil return line is important :thumb:

I know it sucks, I've installed my oil pan/dp like 3 times while fitting everything together for my turbo setup.
But you're going to be really good at changing your oil pan after all this practice :woot:

#122617 I just did mine, too bad you aren't local or I'd say swing by!
Keep in mind the pan is steel so you'll need a steel fitting, can't weld aluminum to steel.

It actually is a steel fitting, when I bought it, I meant to get it welded in, but when I was doing it, I totally forgot about welding it, and I just put the nut on the other side and JB'd it, I should have just done it right the first time :cry:
