Well good news and bad....Good news first, turbos are on and oil lines are not leaking! Bad news.....I took the car out just easy cruising for a few miles before getting into boost. I drive 4 miles and pulled into a car lot for good lighting. I got my flashlight out and laid down at the back to take a look for leaks. There it was. Steady drip of new Mobil 1! Not from the turbos or the oil lines at all! Drivers side and appears to come from above the head. Limped it home and backed into shop where I have spent two weeks of meticulous work swapping lines and turbos.
I pulled Y pipe and alternator to see if any oil is on top of the engine. Nothing from what I can see! Got tired and surrendered for the day.......a 1967 Fastback looks good sometimes.
It drops steady when running. It seems to be coming from above this coolant pipe. Variables to consider: I lowered the engine a few inches and changed oil/filter as well but didn't spill a drop. Installed passenger side oil return line to turbo, both turbo oil feed lines, turbos, 5 bar FPR. Quick pic I took as I was grumbling something about dang European cars....thanks for any advice!

 

Hey buddy calling you now.

 

i have a large flat pan for catching fluid from auto zone. i lay it under the car and then spray the entire area down with brake fluid to clean everything up. wipe the motor and the pan down and wait a bit to see if you can find the leak from there. its much easier when its all clean and dry

 

Thanks! I cleaned pretty well and found in pic 2 the leak is coming from above down the gap just above that coolant pipe. I'm at a loss because the area behind the alternator is dry unless it is leaking under the large cast bracket that holds the alternator, AC compressor etc.

 

the oil feed line on the drivers side comes from a fitting just behind the alternator. did you remove that line when you did the turbo? possible loose or cross threaded?

 

32 yes I replaced it. Completely dry bro! I thought that was it too but very surprised to see it clean. I even ran car with filter and air box off so I could see if it was leaking. I hand tightened the oil lines to ensure they weren't cross threaded before tightening down. You should see my hands lol.

 

It's not coming from where the oil filter bolts to the engine? I would say take the alternator off and take a look. You will be able to run the engine without it enough to get pressure and see the leak.

 

Oil filter sealing properly. It is probably something simple.

 

Agree. I just got a HD borescope inspection camera so gonna take a peek with it running!

 

LQQK thanks for the tip! I found it! No way I woulda been able to without the inspection camera and removing alternator then running it for a minute. Now to figure out what line it is and how to access it!
It is right under the big cast aluminum bracket that hold the alternator, AC compressor etc.
see the video scope pic and that's the leaking point. The shiny gasket fitting.

 

Pull back a little bit and take a picture. I just built this whole thing and I can't tell what it is.

 

That's the best I can get pic wise but better yet it's what the drivers side oil feed line screws in to on the engine side! Appears to be leaking between it and the head. Not where the oil line goes in. I'm trying to locate it on the archaic diagrams!
This pic shows the block that the oil feed line plugs into. It's probably the gasket between that and head.

 

If it is leaking right where you circled, that line goes from the chain tensioner to the top of the check valve on the turbo. You might have cracked it at the fitting when moving it around to install. There is no seal for that, it just presses in on the line when you screw it in. You will probably have to order a new line. Hopefully you can weave it into there with your motor in the car still.

 

I already replaced the line - not leaking there. I just removed the culprit. The gasket was toast. See pics.
I bet when I was attaching line I pushed it just enough to make gasket crap out. I'm assuming I can just replace in reverse order. It appears to be a chain tensioner cover gasket.

 

glad to see you found it! almost always the issues are were you were working at last!
