Weird problem: white smoke only when downslope
I just bought a chinacharger and after installation, my exhaust is smoking whenever my car is doing boost at downslope.
I am suspecting the following:
- Turbo oil seal is gone (but if it is, why is it only happening on downslope?)
- oil return line below oil level in sump
- not enough diameter of return pipe
- poor engine ventilation causing backpressure in oil sump
My turbo oil return orifice is face down toward oil sump.
Anyone with similar experience?
