Turbo oil drain locations in oil pan???

[core-rider]

Where are you guys putting the oil drain in the pan for supercharged or turbo applications? It looks like just behind the motor mount in front of the dipstick, or in the front of the pan on the driver’s side are the only spots with enough space to work in. Just unsure of where exactly to go without having clearance issues internally. I’m worried in the front will cause clearance issues with the oil pump. Show me your locations… pics would be most welcome!

Also, where can I source a long fitting to screw into the oil pressure hole so I can have a place to put the original pressure switch back and also a spot to feed oil to the turbo? I've seen others using them, just not sure what to search for.

Most drill and tap a hole in the timing cover. Can’t remember the part # but there is a fitting that I bought from summit with info from Jamie V I believe.

I used standard fittimgs and made my
Oil feed to have multiple outlets.

Picture below shows the oil feed and the drain plugged off because I didn’t have a power adder at the time but was preparing for it while I had the motor out.

Here's the fitting https://www.summitracing.com/parts/prs-1061

My return is in the pan, I'll try to get a picture of it tomorrow.

I use a standard tee for the feed and pressure sending unit with a close nipple. I don't think it's possible for me to get a picture of that.

Mine is right in that front corner. I remember the front main cap or something being right behind it but it works.

also. ASAP. That feed/oil pressure sensor piping setup you have is a NO GO. You have to shorten that up. It will not last thru vibrations of driving very long.

@ASAP is the drain that plug right beside the oil pressure you’re talking about? Hard to tell from the pic.

@FlatOut that’s my main concern is space behind where ever I put the hole. My friend has a punch he made that will start with a 1/8” hole and as you hammer the punch in it will round the sheet metal inward to create some meat to then tap threads for a pipe fitting. The punch is a couple inches long so there needs to be space behind the hole for it. I’m doing this on the truck (I know very sketchy) but I’d rather not go through all the hassle of pulling the engine if possible. This was his method for countless blower installs on Fox bodies back in the day with no issues.

I welded an 10an bung on either side of the pan where the front crank jurnals are to help with splashing .
For the feed, i found a company, think its call A1 fittings. That makes a solid aluminum block with threaded npt ports. It has both turbo feeds, oil pressure sensor and factory sensor in it.

I forgot about that Travis. I did end up shortening it up before install.

Yes it looks that way but it’s actually in the front cover and oil pressure is from the block a little further in.

Mine drains to the valve cover. Very simple install and it doesn't leak.

Mine is in that front driver's corner of the pan as well. I have a full flow AN10 90 into it there. I like the big drop out of the turbo.

I had mine to the valve cover way back in the distant Vortech past, and used that again when I had the original journal bearing turbo on it, but it wasn't enough drop or volume once I changed to ball bearing.

Thanks for the pics @FMOS Racing... Luckily I had the opportunity to view an engine with the pan off today and think I'm going to a spot just in front of the dipstick. Your location at the front will work, but I'm not removing the pan for this... I know, I know!

I plan to drill a 1/8" hole till it just barely starts to break through, then a friend of mine has a tapered punch he made way back in the day when he was installing blowers on everyone's Fox-bodies. It will enlarge to hole to 3/8", while also bending the metal inward to give more meat to tap for the fitting to screw in. I plan to drill out the inner diameter of a -10an to 3/8" fitting to 0.50" to help maintain flow through the fitting. I may eventually have the fabricator weld the fitting as best he can in place. Hopefully it all works out.

Anyway back to your front location... the oil pump is right near there and I don't think it will give enough clearance for the punch. The location I picked has nothing in the way so it should work.

I did mine at the front with the same method you are doing but I did have to keep shortening the tool bc there was interference behind it as you are suspecting.

I originally did mine the same way. It eventually leaked, so when I had the pan off, I installed a fitting. I actually ended up with JB Weld on the inside and outside of the pan, which I then drilled and tapped for the fitting. I put more JB Weld around the fitting to support it. It's been that way for about 10k miles and OK so far.

This was a case of being in a hurry and making do with what I had available. I couldn't do a bulkhead fitting because I was into the curve of the pan.
