We are in the belly of the beast now. Fixing screw ups, finding new issues, and doing really boring stuff like running new brake lines. I replaced the leaky fuel fittings and both fuel pump relays. All is well on the fuel side. Still waiting on one -10AN fitting to complete the PCV system. I think the boat driver got lost. PS pump is still leaking a puddle when running, haven't looked into that. And this turbo smokes like a freight train!!!
So I hit up Viren at VS Racing yesterday (Sunday) through PM. Didn't really care when he responded as this is no rush. He proceeded to have an entire conversation with me about my issues. Props to VS Racing for that. I sent him the two pics below of my drain line. He told me a couple things I didn't know. For one, he recommends a -12 drain, which I have a 10. He also does not like the 90 degree bend off the turbo. 45 would be better. I'm pretty sure that is a Teflon drain hose which even further reduces diameter. I also have some other things working against me, very little downward slope on the drain, and 70 psi of oil pressure at idle. I'm not moving the turbo, I'm not pulling the pan back off and putting in a -12 fitting, I can't change oil pressure. So we are gonna start with the easy stuff first.
Here is the 90 fitting, and an idea of the small amount of slope going back to the pan. Pretty sure the rest of the hose is about level. Understand, there is some force (residual pressure) coming down the drain line, it's not 100% dependent on gravity. But may be "sensitive" to it.
The wet leaking can be seen here. It's literally dripping inside and outside the turbo. This causes massive amounts of nasty smelling smoke.
So I'm changing the drain line from -10 teflon with 2x 90s, to -10 standard AN with 2x 45s. Not sure how much this will help but we are gonna see. Plan B is a restrictor. Turbos need oil so my plan is measure the inlet fitting, say its .250, weld it solid, then drill it back out to half so .125. Then keep stepping down (welding and re-drilling) till the smoke goes away. I want the minimum restriction possible to fix the issue.
On a plus side the rear brakes are all done from scratch and finished. Well sort of, I had to order some brake line clips to hold the line to the body. Then final tweaking to avoid any contact where rubbing could occur like in this pic. I may go back and route the line through that crossmember hole. I put this under the driver front floorboard just to keep it out from under the hood for less clutter. I did not follow the stock routing to the driveshaft tunnel because I don't want the lines there in case the DS goes kapoot. The line and valve are nowhere near the lowest thing on the car so I'm not super worried about it. I'm pretty sure I will be redoing most of it because all my flares will leak. Oh well.
