Oil Drain Lines - This has been a pain in the arse!
The first drain line, that was fitted to the car, was a cut down VW jack. but it wasnt welded properly so leaked. Car turned over and ran brilliantly, no smoke, but was losing oil from where the sump fitting was welded. with the inability to get the welding torch on the upper side of the sump, I got Rolo to weld an spare fitting we had in the unit, 1/4" BSP!
stripped the exhaust and sump off, fitted the new sump. got a return line made up, refitted exhaust, fired car up and noticed plumes of oily smoke out the back and oil dripping down the downpipe!
BUGGER!
THe oil drain line was too small a bore!
So got some adaptors and some 3/8" tubing made up, drilled out some of the fittings to put less restriction on the flow, but the oil drain line sat under the subframe, so when the engine rocked backwards under acceleration, it would rip the fitting off! so jacked the engine up, fitted the oil line above it, dropped the engine, snapped the fitting!
BASTARD!
so after spending 50 pounds on fittings and lines that were at best a pikey fix (of which I knew, I was just putting off doing it properly, as I wanted it done quickly) and having to take my sump off three times, I bit the bullet and spunked out 76 quid on some gucci AN10 stainless hosing and aeroquip style fittings.
Made a boo-boo by buying an alloy weld on sump fitting, and was told by Chris that I cant weld alloy to the steel sump!
DOH!
not too bad, as the peril has an alloy sump made by RPM. so trundled off home and whipped that off, went to see Phataz, who welded the fitting to the alloy sump and we went off to the unit happy as larry.
Had a right pain in the arse getting the fittings on, and dethreaded on of the fittings and my good mate accidently dethreaded the alloy sump fitting, so the sump had to come off AGAIN, back to Phataz, who welded on the 2nd weld on sump fitting i had spare.
Another 40 quid on 2 new fittings, to replace the dethreaded aeroquip fittings, and some patience meant I finally had a proper, non-leaking, suitablly large diameter oil return line.
Pics of said oil line & fittings :-
I think the 5 minutes the car had ran with the wrong size drain back line had damanged the oil seals, as you can see the leak at the base of the turbo in this pic.
So £166 quid lighter, I finally had a kushdi oil line and a buggered turbo! This was one expensive lesson, in doing things properly from the off.
Video of the car as she is now, running and schmokey!
Does anyone know of companies that supply oil seals for Garrett Turbos?
Also is anyone running restrictors in the oil feed lines?
