Hey, I've been looking at this for a while and I'm trying to figure out how they are returning the oil without tapping the pan/block. Has anyone bought the kit to know where they return to?

 

Through the side cover.

 

take the drain plug out, and replace it with an an fitting

 

how much is this kit running?

 

Anybody got any pics of the return? I knew the oil feed was through the plug, not sure about where it returns though.

I think the kit is like 140, but if I can figure out what fitting they used I'll just go to lowes and get it.

 

Here is the oil pan plug replacement.







The oil feed into the turbo comes one one of these

 

Haha, what the ****?

I suggested doing that for the return and everyone told me if was a stupid idea. I guess there's no problem with that being too low and under the oil level? That's awesome, I wonder if I can get that size at a lowes or hardware store? Anyone know the size? I'm guessing that's probably going to be hard to find in a store.... Maybe Hahn will sell me just the fitting.

 

Im pretty sure Hahn will sell you the plug. Looking over by invoice I think it is part number H TZ-5340 I doubt you're going to find a ecotec drain plug with a hole in it at Lowes

I didn't use mine and gave it to a friend for his turbo. it is working fine for him

 

He's got it tapped looks like, unless SS/SS's have a top plug too. 2.2s don't have the top drain plug.

I'm thinking putting it so low is going to cause backup.

 

that's my car. I had a bung welded in at the top of the oil pan for the drain. The oil pan plug is the one below

 

Oh, so the Hahn one DOES intend on using the bottom drain plug?

If so, that doesn't sound like the smartest plan. But, if it works it works I guess.

 

Yeah, it seems to work fine even with the drain plug being the lowest part of the oil pan

 

you mean like this...

or this...

 

Thanks a lot guys for all the pics, I'm planning on using the same kind of line, it's high pressure hose.

I don't think stainless is totally necessary.

 

ask and you shall recieve!

turbo guys love to help turbo guys... it those heaton's that i dont care for

 

saving. .

 

Looks like I'm not going to get anything back from Hahn, sent them an email yesterday, haven't heard anything.

 

ok they wont tell u how it run but its like this

oil leaves turbo, goes into a tee, small tee leads into the water pump plate on the passenger side of the engine, u can see if witht he wheel off, its held on by 4 10mm bolts, its sort of a circle shaped thing, than the big part of the tee leads into the drain plug fitting, u can make the kit urself for ~20bucks if you go to a hard ware store, u need the following

drain fitting for turbo(with barb'd end)
a tee with the same in/out as yoru turbos fitting, and the tee to be 1/2 the size of the main hoses
a 90* npt to barb fitting, same size as the small tee
hoses
clamps


and than route it all urself

 

a few of those pictures in them selves prove that its a flawed system.

see the oil puddling and dripping from the bottom of the exhasut housing on the 3rd pic?

on a journal barring turbo in witch you use full operating oil pressure(not all journal barring turbos are like this) i could see this possibly working as you'll have enough exiting oil pressure to over come the oil at the bottom of the pan, however on a DBB CHRA this would be epic and total fail. as those CHRA's tend to operate at oil pressures in the single digits.

 

if this would work, then y would you need the drain plug to have a hole in it itself? considering that youd have to unscrew the fitting either way to drain your oil. or just unclamp and pull off hose

 

QFTT. I gotta buddy with a turbo'ed engine swap civic. He was having the problem of the puddling since he was running the return directly into the oil pan plug.

He is now using a new engine and new turbo with a proper oil return. Can you guess why he went with an entirely new setup?

 

^^^^^ cuz this crap=FAIL!!!!

 

I also have another friend with a turbo LS civic. His turbo crapped out on him using the oil pan plug return. He is now using a new turbo with a proper oil return.

 

then FAILx2

 

I really wanted to avoid tapping the oil drain boss on the block, but looks like it's the best choice at this point.

Anybody have an alternative?
