i was thinking about it, 99 percent of stock cars with turbos dump the oil from the return into the oilpan, i know alot of first gen turbo guys if not all run the return to the front cover, i was just thinking and i really think it would work, have the turbo oil return go back into the oilpan, get a fitting drill tap bam yer done!
now i really havent heard of anyone doing this on a turbo first gen setup, is there something im missing?
i really think it would work
i want alot of feedback on my idea

thanks guys!

you can do that but remember the turbo is gravity drain,,,, so.... you would have to run he oil level lower than the fitting in order for it to drain properly.....hence thats why the factory put the drain where it is....p.s. your fpr is on its way!!

There waas a thread about this recently. I decided to install the return line in the front cover but after reading about several peopel who went back to the pan; I did it that way.

It was much easier and cheaper that way.


Thanks for sharing your thoughts.

How is it cheaper to do it in the pan? Just drill the front cover, tap it, and put in the fitting. Pour some diesel straight through the oil system to clean out any shavings that might have gotten in. I don't see why putting the return in the front cover is considered "hard".

I drilled and tapped a front cover just yesterday. Easier than doing the oil pan.

While it was on the engine, also? Pulling the pan is a lot easier than pulling the front cover....

I think you meant "while it's in the car". But yes, that's why it's easier. And if you have a low mounted turbo like me, the front cover is too high.

yeah my turbo is pretty low, ill figure it out

7/16 drill bit and 1/4 NPT tap. This is your typical Camden supercharger oil return fitting. http://www.camdensuperchargers.com/index.php?pag=305

in order to allow the oildrain to work properly Elford (uk) had a sort of collect can mounted next to the pan, which overflowed into the pan. This is a whole lot more work then a "simple" front cover mod. I guess they'll know why they did this that way instead of simply draining to the pan. This way they could drain the oil without having to worry about the drain being under the oillevel.

I drilled and tapped my front cover while it was still on the engine in the car. Wasn't a problem at all.

coldy did you drill and tap in the same spot as camden super chargers or did you do the oem spot on the jspec engines?

coldy13

I tapped where there was the indent on the front cover, right next to/below the OMP.

Well, I just got a 1/2 npt tap off ebay, now I'm looking for a 45/64 drill bit. cant find one will fit a 3/8 chuck so I think im going to go with a 11/16 inch bit its only 1/64th off. I'm hoping the soft aluminum will be forgiving for the 1/64th. I have another front cover that I'm going to try it on first.

I did the same thing, worked fine, just try and wiggle/dremmel out the extra 64th.(i used the dremmel, worked well)

I drilled mine in basically the same spot as in the camden pictures. My OMP was in the way, so I had to hold the drill motor so it wouldn't hit the OMP. It still looks like the fitting is in almost the exact same position, though. Close enough for me, anyway. The front cover was on the engine, but the oil pan hadn't been installed yet.

Yeah, the 7/16 drill bit cut through the aluminum very quickly because I already drilled a pilot hole. Man, it cut so fast, and then the tap cut very fast too. I hardly had time to enjoy the process.
