Found out that I'm leaking a fair bit of oil from the turbo oil supply line (banjo bolt on the motor side). I think I'll let RS Motors handle that one. If the line needs to be replaced then I've heard it isn't much fun due to the tight workspace on the turbo side.

I discovered a leak on my car in the same spot just this past weekend. I gave it a 1/16th turn to torque it but if the leak persists, a new set of copper crushwashers will go in. It's a tight spot but w/o an undertray on all I needed was a 17mm socket on the end of my flexi ratchet and it fit right in. They are sometimes a small PITA when replacing the crushwashers because you have to re-align the banjo bolt. The bolt wants to go perfectly straight in the head of the feed line and if that is off-kilter even a little (which is easy to do) it will not want to thread into the block. The solution is to pull it back out and very carefully tweak the line itself so it is straight then try again. Oh, and oil drips out of it the whole time too

I'm already loving and hating that SSP undertray. I wonder if it matters much for aerodynamics or not. Oh, well.

I've been reading around about oil leaks and it seems like the most common place to leak is from the timing cover and a lot people mistakenly think it is coming from the turbo oil feed. Mine leaks more than a few drops so it probably is the oil feed.

You probably just need 2 new crush washers. They should not be reused...but most people do.

Yeah, just need to figure out what to buy. I think I saw a box of assorted crush washers at Northern Tool last week. Ron said the same thing about re-using them but I'm guessing that DB wouldn't do that.

I'm sure it helps with aero, no question. Maybe take the time to fit some dzus fasteners while you have it off

Looks like they're about $3/ea. Not terrible but the tray probably requires a couple dozen. I'm not sure how they account for depth (if they are loose and allowed the tray to bounce then that won't work). I'll have to measure the D-rings that SSP sends for depth. The dzus at 12mm don't sound very deep relative to the stock holes.

OEM parts! I undoubtedly overpaid for it but it's exactly what I needed and the guy gave me a nice amount of lead wire on the plug. fuck yes.

**scheides** · 05-19-2011

Yee haw!

**Kracka** · 05-19-2011

Glad you got what you needed!

Now that I've inspected the stock hanger more closely, it's a rather elegant design. A part of the return fuel is used to create flow through a check valve at the lowest possible point. I'll genuinely be surprised if it doesn't solve my issue.

Scheides texted me saying that he was seeing identical symptoms...a 300lph pump isn't even enough for a BBX on E85...it leans out above 7k. That's why I ended up installing the BAP. It borders on nonsense how much pump the X needs for E85.

At this point I'm planning to get the stock hanger w/Jay Racing 340lph pump into the car. I'll test that on the road course at Proving Grounds next month. If Scheides ends up with the same results that I had (needing the BAP) then I'll proceed with installing the Weldon in July.

That was the very first thing I noticed when I looked Scheides' hanger over.

Those Mitsu engineers got something right; it's cool how things like the return can be designed to serve an important purpose. Hope this is the end of your fuel issues.

My timing cover leaked. I got it covered under warranty

Even after cam install and E85 Fpred etc etc.

WARRANTY! DO IT!

**mlomker** · 05-22-2011

Decided to order a 1/4" tq wrench to snug up that oil line bolt. If that doesn't fix it then playing 'find the oil leak' will be my next adventure.

I got the stock fuel hanger half installed this evening (spent most of the afternoon hanging out with simulatedwood & Toothy while they did brake jobs). It is clear that the FB hanger does not sit on the bottom of the tank--I've always wondered about that and assume that the stock hanger is spring loaded for a reason.

**Murlo26** · 05-22-2011

IF I remember right, the blaqops double pumper gets rid of the springs. It just uses good ole gravity and the weight of two pumps to get it to stay low.

Gravity would be inadequate when the car is bouncing around. I doubt that they removed the spring since there'd be no good reason to.

In any case, I haz stock hanger.

FWIW if the initial torque doesn't fix it, replacing the crushwasher should still be the next step. When I installed an IX turbo on my VIII I accidentally got a teeeeny grain of sand on the fitting and after about a month or two I noticed a fine mist developing on components immediately around the feed banjo bolt. I took it off, could clearly see the grain of sand wedged into the copper, gah! Fresh washer and very careful to make sure all was clean and it was very clean from there on.

Woohoo!

Why is the pump hanger thing able to move at all? shouldn't it be stationary in the tank at all times? Seems illogical to be moving around. One more part to cause problems.
