ecotec swap (Page 17/98) wftb MAR 13, 06:41 PM i managed to rotate the turbo and now i have a downhill slope on the oil return line but the leaking problem is still there.i am not ready to give up on the subaru turbo just yet ,but for those of you thinking of doing a turbo ,i think the subaru is not a good choice .to get the oil to flow properly ,i am pretty sure the return pipe has to point straight down . that would require a custom manifold , one expense i am trying to avoid . i may try running a pump on the return line to create a vacuum but this might be just good money after bad .the only electric oil pump i have found so far cost 175.00 at summit racing.i am going to try ebay and see if i can find something cheaper.i cant run the car the way it is because it is also leaking oil into the intake charge pipe. wftb MAR 13, 07:01 PM wftb MAR 14, 01:57 PM when i did all my research into doing the turbo install ,i completely missed finding anything about turbos that are mounted in non OEM positions.since my turbo is not mounted at all similar to the way it would be in a subaru ,the oil will not drain properly and causes the seals to leak into the exhaust .the drain pipe needs to go straight down in order to drain properly and this is impossible using the stock cavalier exhaust manifold .this is also a problem with all low mount and rear mount tubos , as i found out while looking into scavenger pumps .i found a site showing a rear mounted turbo cavalier and he has used a shurflo pump for 15000 miles with no problems .so i called our local TSC store and they have one in stock.so i am going over tomorow to get a pump and i will have it installed by friday .and the snow is now melting so i should be able to test drive it on sunday(unless it snows) Fosgatecavy98 MAR 14, 02:16 PM Lookin good, yea we had a 70 degree day yesterday!!! woohoo!!! didnt get any work done tho. You gonna get any videos of that thing running, I bet it sounds nice Primaris MAR 14, 02:35 PM Try a much larger return line. 2x the input line is a rule of thumb. (I thought I stated this reply already with a link too. If I did or if I didn't I'm blaming it something or someone else cause I can't be to blame!) wftb MAR 14, 03:10 PM i tried a bigger return line already.the return line improvement changed it from leaking all the time to just leaking till the engine oil is fully warmed up .i think the pump is the only way to fix the problem . the engine has a nice sound to it and it is quieter than it was with the muffler.the only difference is it makes more noise when you back off the throttle quick .but i should be able to fix that when i do some proper tuning. wftb MAR 17, 04:12 PM i hooked up an oil return line pump and the oil leak problem is now solved .i havent driven the car with the turbo on it yet but it is driveable now.i still have to repair my leaking cv boot and make my new centre consule and then it will be on the road again. Fosgatecavy98 MAR 17, 05:26 PM Looking forward to some reviews of it sYkboy MAR 17, 05:43 PM I feel the ugly monsters of envy and jealousy stirring! AquaHusky MAR 19, 12:11 PM I just did a quick glance thru, and I wanted to say something about the ECOtec. You'll NEED a 1 1/4" socket for the oil cap. I just got one and changed the oil in my VUE and I was about 30 minutes faster doing it that way instead of trying to fit a wrench in that tight space. Just thought I'd pass that along for anyone wanting to do this swap.
