Just wondering if you guys knew of a place on the block where it would be easy to tap your oil return line into. I haven't had a close look at a B16 block so I don't know. I was wondering if there was a plug you can remove that would allow you to tap into a place on the block that would let oil just drip right back down into the pan. Kinda like a freeze plug lets you install a block heater into the coolant side of your block.
So, anybody?

 

Check this thread. There are a couple pics of where a good place is.

Yep, that's what I'm talking about. Great idea. I PM'ed him about what kind of work he had to do for that setup. Thanks for the link.

 

just out of curiousity, what would be the reason for doing it like that, as opposed to the pan? i'm guessing its used on some setups so that the line is clear of the downpipe, but i dunno...?

any advantages/disadvantages?

 

The advantage is that the return line is up so high that it doesnt have the slightest chance of having the oil back up the return line and then sit in the turbo...which in turn makes it so that you dont burn up your turbo seals.

 

wow i really like how he made a brace for his turbo for support. great idea.

 

Just open up oil cap and route oil return line to the valve cover, classic trick

yea me to.. does anyone have any pic of the whole motor and that setup?

 

The motor is a
B18c5
Stock Head
Je Pistons
Crower Rods
Ge SLeeved Stock Bore
T4 Turbo not sure of the specs
Apexi Power FC
GTR Intercooler
534whp/340 Torque

I think I got it all right.

Oil isn't going to back up into the turbo at the normal mounting height.

Edit: What do you guys think would cause the oil to go up the return? I can't even think of a single reason that would happen...

 

If you have so much as a small kink or the line is not postioned completly down it will cause oil to back into the return. This happens to many people depending on the set manifold, turbo, dp ect etc.

 

Oil won't back into the return, it simply will not be able to flow out.

I don't understand how moving the drain point, while still having it at the same angle with regard to the turbo, will help with the line kinking.

 

i suppose it's also possible for the oil in the pan to block the return oil from entering the pan...

 

well the oil could flow back up the return line if your drain out of the turbo is lower than the hight of the oil in the pan, but if the starting point of the oil flow is higher then the oil in the pan then it should flow fine, you would think

 

Isnt the oil coming from the turbo all foamed up and hot? Sending it to the block from the turbo where it need to be at "its best" so to speak sound like a bad idea? Just a thought...

Actually from the looks of it, that block tap is just going to have the oil drip right back down into the pan. It's not hooked into the oil supply going up the head or anything. I just wanna know exactly WHERE that part on the block is at.

 

I have heard of some people routing it into the dipstick tube..

excessive crankcase pressure.

Umm....

1. In order for the crankcase pressure to be great enough for the oil coming out of the turbo t move backwards, it needs to be stroung enough to overcome the pressure differential across the bearings; I don't know how high the oil pressure is at the pressure sender location that most people use, but I propose it sure as hell is more than a couple psi. Do you really have that much cankcase pressure?

2. It is likely that an increase in crankcase pressure would also increase the pressure within the pressurized portion of the oil system, which means that as crankcase pressure goes up, oil pressure may go up too. Just another reason the oil is not going to overcome the pressure in the turbo.

3. This fix does absolutely nothing to deal with a problem of crankcase pressure, as it just moves the return.

 

Anybody else have a similar setup like this pictured above?

all the sr20de boys down here i know do it that way (into the block). it should be no problem as long as it drains into an oil passage in the block that goes back to the pan. the advantage of it i see is just making it easier to route the oil return line.
