What is the best way to do the oil return?

1. Bung in oil pan

2. Drill and tap dimple in block with 3/8 to -10AN?

Pictures would be most helpful!

 

Oil pan. Weld bung above oil drain plug

 

Do 1/2" NPT, 3/8's is too small

 

1/2" NPT to -10AN flare is what I meant. So you would suggest tapping and drilling the block?

 

No. He specifically said the pan.

 

Is all he said. he did not mention pan or block. Thanks

 

see post

 

Waiting for other responses also. Thanks

 

Lol. Its not rocket science bro and if this is to you, you are not going to have a good time with the rest of your build. Oil pan. Weld it. 1/2".

 

Thanks for your opinion.

 

 

DONT tap into the block for return

weld into the pan like Cherry GT's pic

 

Why is everyone so against tapping the block for the oil return?

That is the way its setup on factory Ecotec Turbo cars.

I drilled and tapped my block for a 10AN line and it has been trouble free.

 

I'm gonna go on a stretch and assume that's because they can at the factory. It just makes more sense to remove the pan and drill and tap for return. Yeah you can drill the block but it's more likely in that case that you may end up it extra little bits in your oil system and it's really not worth the risk. Maybe in your case it's a sense of pride to have accomplished this but for the masses it is just better business to drill and tap the pan and not the block.

 

If you know how to drill a hole (slow) and protect the crank from shavings, I would not see how this would be an issue. I will do the pan as no one has any pictures of this being done. For me its simple as the engine is on a stand and not in a car.

 

Its easier to pull the pan and weld on a fitting than it is to tap the block. Plus, if you **** up on the block youre gonna have a bad time. If you **** up the pan its easier to fix or replace.

 

And the reason most people on this forum do this is because its "easier". Maybe in a car it is easier but the engine is on the stand.

 

But there is no benefit to tapping the block over the pan.

 

I agree there is no benefit, but it looks cleaner.

 

drill away then and let us know how it goes.

 

there is alot of benifit of tapping the block over the pan if you put your return in the pan then you have to push the retuen oil through the oil seting in the pan and back pressure on the retuen side will cause the seals in the snail to pop if you put it in the block where its supposed to be then you will not pressurize the retuen system from the turbo and since you need to remove the pan anyway its not that much harder to drill and tap the block even in the car and use break parts cleaner to hose the shavings from the block

 

You asked a simple question, coulda searched. you got accurate simple answers; why are you arguing with everyone about it?

I would put the ****** in the pan above the baffle, then no issues with oil backing up
