2nd oil port

[bayou]

were is a good place to pull oil from for my 2nd turbo? im already using the one on the driverside of the block, thanks

there is one right above the oil filter on the oil cooler assembly. IIRC its 1/2NPT.

Nope... Any oil taken from the oil cooler head is not filtered yet. There are 4 main oil galley ports on our blocks. The one you are using. Then there is the oil pressure port top of the block behind the dcr. And then there are two mostly hidden ports behind the oil cooler bundle. Those two are nearly impossible to see or reach.

Couldn't you just tee the one you are already using?

Your best bet is the one in front of the oil filter on the crank rail.

Thanks Mel. Thats one of the nearly hidden main oil galley ports. Looking at the far right of your picture you will see another port.. Thats not an oil port but a coolant block drain location. But I'm sure if someone actually removed the larger plug they would see coolant and not oil. That plug usually gets an okie ****** coolant drain installed. Same wing nut drain found on the bottom tank of the radiators... Makes draining the blocks so easy.. Some of those drains even have a spout on them that will accept a hose. Then you can drain into a pan or at least direct the flow where you want it..

There are three on the driver's side of the block as posted above. The rear most is the one used most often for turbo oil supply. The one Mel posted, and another behind the motor mount that you can't see or really access. Photo below. And the one at the top rear of the block on the passenger's side like Gary mentioned. Photo below.

Here is the oil flow. The second pic is prolly where your 1st turbo oil supply is from. A turbo engine has that port drilled to 1/4" NPT, any other port you see is 1/8" NPT. As you can see in the oil flow pic, each main is cross drilled and a pipe plug is installed.

So if those ports are really an evil necessity as part of the machining process, where is the one for the front main? You'd think there would be one, right? I know that one that hides behind the motor mount is the one that IH uses to feed an air compressor with.
