I have to hold the wrench on the crank to keep the valves/cams from moving to get good leaks own results.

Thanks guys! Will try again. I did get a 100psi gauge for the HF tester.

Just been driving the car and breaking in the motor. Also chasing a couple of annoying issues. First is that I'm not holding fuel pressure when the car is off. So I have to crank it twice to get it to start. I replaced the pump, line and rail with Radium Engineering items so it is likely one of those is leaking... I eliminated the rail and line so I'm betting it is something in the fuel pump install.



Second when I run the VANOS test, I get an "advance time too long" error. All the times are pretty slow so I don't think it is seals. I interpret it as the VANOS is not responding as fast as it should because the pressure is too low? Car runs fine but going to ty replacing the pressure relieve valve and see if that helps.

Spent Saturday trying to sort out the open issues plus a couple new installs. I have dyno time and an alignment setup for Thursday, so got to get everything sorted before then!



First I took the fuel pump back out to try and sort the pressure leak, and it is definitely the line from the pump to the carrier. I replaced that with the Radium fuel line and its almost like it is too big, I cant get it to clamp down and seal. Guess I'll call them on Monday.

Second I installed a new VANOS pressure regulator, fingers crossed that helps the VANOS response time.

Also chased down an exhaust rattle the was driving me crazy. Turned out to be the heat shield on section 2 had broken its mounts. When I took it off it left two holes:



I plan on replace this longer term with a 3.5" pipe, so quick ghetto fix applied! It worked :]



For new stuff I Installed a lighter battery I picked up from @Shainz. 20lb weight difference!



Also picked up some Turner adjustable sway bars from @Vmals89. Will install those later this week.

Just went thru your entire build thread, very satisfying to see the progress/work put in it. And for a track car you sure keep the car clean, great job!

Thx! Pumped that it's finally 100% back together, time to hit the track!

Couple quick updates:

First I got the fuel pump sorted out. The leak was in the line from the pump to the pump carrier. Ended up using a smaller hose for a tighter fit. Lesson learned there, don't fix what ain't broken... In hindsight I would just leave that line alone and only change the pump.

Second, replacing the VANOS Pressure Regulator made a huge positive difference in the VANOS response times. I'm now confident the VANOS is 100% healthy and performing.

Dyno number's!! Made it over to RK Tunes last week to check the tune and see what power the new motor is making. I'm still using Jordans custom Alpha N tune from last year. Been very happy with the drivability and it passes NYC yearly inspection.

Overall the tune was still close but a little lean. After a bunch of runs we landed on the following:

358 HP
272 Torque

I'm pretty happy with that, especially the torque. I'll attribute that to the higher compression of this motor. Heading to Lime Rock this weekend to test it on the track!!

Also while I was on Long Island I went to TKX Performance to get a corner weight and alignment. Pretty cool shop, especially if you like BMWs and Porsches. Car weighed in @ 3130 Lbs
