How critical is the draining of the oil from the turbo back to the engine?
For the turbo that is not going to be installed on my car, 'cause you cannot turbo a 914, I'm toying with mounting the turbo either right behind the collector on my header (see second picture...red outline on header, mine is similar to the one in picture....) (a la' Chapman's 3.0 turbo setup with turbo in the back) or use a mandrel bent U bend pipe to locate the turbo up where Ben M (airsix) has his turbo located (IMG:http://www.914world.com/bbs2/uploads/post-2-1095059341.jpg) Since the oil going to the turbo is pressurized, shouldn't the oil have no problems getting out of the bearings of the turbo and back to the motor without assistance??

Hey Mike,
I cringe every time I see that pic (at top). I've since trimmed the rear engine tin so it's nice and clean back there (unlike the mess pictured). Here is the same pic with the oil drain line pointed out in case it's not clear. I used 5/8" hose with a spring inside. The spring is so I could make the very tight bend to get around to the valve cover. The line is only about 8 or 9 inches long. It goes straight down about 4 inches, makes a 90 degree horizontal bend and then goes about another 4 inches horizontally to a 90 degree elbow at the rear of the valve cover. I havn't had any problems with the turbo seals, but I have new leaks on other places to deal with. -Ben M. Attached image(s) |
