Hi Guys

So I need some urgent help. Ive installed my new turbo , took me quite some time to remove the old one and fit the new one back in , but now when I start the car oil pours from the actual fitting from the block to the turbo oil line.

I used this kit :

The flange itself is triangular shaped with two holes that slots on to the block. Ive tightened the turbo oil line fitting and those two nuts on either side but its still leaking. It doesn't drip it literally gushes out. Even if I didn't tighten the oil line properly it should leak not pour oil.

-Why could this be?

-Is it possible I could of cross threaded causing a leak?

-Is this a common problem with the 7m

Its really difficult to get to since the turbo is now installed(and im certainly not removing the turbo again as it took me hours to put back on),so its taken me hours to tighten.

Help please , just did a whole slew of mods so my car has been off the road for the past month and this is the only thing holding it back.


Thanks in advance

If I'm not mistaken I think there's some copper crush washers that goes on with the fitting. Did you remember to install those?

Yes, you need copper washers.

EDIT: Correction, copper washer are only used on the turbo feed line that uses a banjo bolt to bolt onto the turbo itself. They supply a gasket for the flange that bolts to the block. If you used that gasket they supplied, and it's tightened enough I can't understand why it's pouring oil from that area. Did it feel like you crossthreaded it when you were tightening it?

Take the oil line off and inspect it for any damage.

yup its going to be a bitch of a job with the turbo in the way but I guess i have to remove the oil line to inspect it.

No it didnt feel like I cross threaded it but to leak that much oil maybe I did.

Any tips on removing oil line to make it easier(took me almost 2 hours previously) ?

leaking , well pouring rather ,not from the banjo bolt but from the block itself to the left of the banjo bolt(i believe you called it oil drain).

Ive circled where its leaking from

Didn't use copper washers at all!!! (did the removal and installation in a space of about a week so I forgot)Could this contribute to the leaking?

The picture you showed does not use copper washers. The Copper washers that the other guys are talking about are for the Banjol bolt on the oil feed line, next to the oil drain in the picture. The part you circled is the drain, it just uses the paper gasket, its possible you didnt remove all the old gasket. When I did mine last year it was BAKED to the block. Take it off and try to scrape it with a razerblade/head gasket removal tool. If you just installed a soft line kit, this will be easy if you have a hoist. IIRC you may have to remove the engine mount out of the way.

If it's the flange on the oil drain fitting on the block, either you didn't use a gasket at all, or it could be a warped flange. You'll have to take it off and inspect it. I would get a can of 'The Right Stuff' and make your own gasket with that; put a decent bead around the flange mating surface (make sure you put the bead around the drain port) then put the fitting back on the block. Tighten the bolts until you can see the RTV start to squish, then stop....leave overnight, then cinch down the next day.

Not sure if your gasket had it or not but the stock Toyota gasket has a raised circle in the gasket to help seal it. Also like the others have said make sure you remove all of the old gasket. This was the biggest PITA of the whole turbo swap i did. I removed the two studs (but you dont have to) and went to town on it with some razor's. If you go this route make sure you have a fresh blade and hold it at an angle to the block.

I can't believe no one has diagnosed this problem correctly. The reason its leaking is because it isn't sealing.

Look back at my first post it says that the Old Gasket is most likely still there.

That's why I didn't tell him to crank it down and to tighten just until it starts to press and let it cure first.

I think you completely missed the point of my post. Its obvious to everyone else. Lets not have another Quality Aloshan thread cause an argument, he has already posted the exact same question in two other forums to achieve that.
