t51r-kai smoking after full boost, help!!
I am using -6 for oil feed line with restrictor. Tried -4 no restrictor still smokes. There is some oil going into my intercooler pipe and I assume there must be oil coming out the turbo down to the downpipe. Just had the turbo rebuilt. The car only smokes when I let off the throttle under full boost. My turbo bad or should I keep trying different oil feed line and different restrictor?
Any input is appreciated. Thanks guys. |
why dont you buy restrictor from HKS. or check your oil return line. make sure you have big enought return line. (this happend to my HKS T04ZBB, )
so my suggestion using bigger return line. if still not fix the problem, buy restictor from HKS |
I have the same problem. In my case I believe that the BOV isn’t doing its job at full boost. When I get the energy I plan to hook a boost gauge into the wastegate line to look for a spike when the throttle closes.
My turbo didn’t do this when 1st installed though, its been around 500mi & ~10 dyno runs before the smoking started, so I suspect that the BOV situation has slightly damaged the turbo (too much shaft play I would imagine). |
what exactly do you have for a restrictor? what crankcase ventilation do you have? describe the size, and installation of your return. Most likely, you have an issue with some combination of the above. Carl
