Turbo Oil Supply Line

This job had its moments. It all came together though. I'll know for sure later when I look for leaks.

Removing Oil Sensor



Parts going together. I used some teflon tape on some parts and rtv on others.



Installing the fittings requires retapping the sensor port hole. I think it's just to clean the threads in preparation for the brass fitting. I used a well greased 1/8" NPT tap, but still managed to create some filings. This worried me as it's a direct shot from there - passing through no filtering, I think, to the turbo. Although the grease retained most of the filings, there were some in the block. So, I diligently flushed it many times with brake cleaner and wiped out with a microfiber to towel, then rinsed again. There's no evidence of any filings, so I should be good.

Grease covered tap.

Line attached. I'm going to do a flow test soon. The engine will not start, but I'll look for evidence of oil coming from the turbo end of the supply line after I prime the turbo with oil. Hopefully, starter speed will provide enough pressure to flow oil up and through the line.



After the test, I'll hook up the end to the turbo. Routing the supply line up to the turbo is going to be a bit of a challenge, involving good heat resistant zip ties. The supply line is very long, presumeably to allow keeping it far from hot parts such as the manifold and turbo compressor.
