Well, I'm hoping to be on the road tomorrow, barring more problems. Today I had to fix a leaking water neck on the head, which was a big pain with injector lines, wires, hoses and linkages in the way. I just threw some Right Stuff on it since I didn't have another o-ring. This time I pressure tested it with air before filling it. Got the exhaust wrapped with header wrap, battery box in, alternator in, idler pulley for the water pump on, turbo heat shield modified and put on. I also bought a new Optima so I don't have to worry about acid eating my air hose again. I found the cable for the VNT was very frayed, so I got a new cable for it.
I still need to make sure the fan works, hook up all the turbo tubing to the IC, air filter, manifold ant turbo. The timing sounds a little too advanced, especially with power to the timing solenoid, so I will have to adjust it a little. I need to redo the air filter mount, put on all the body panels I took off. Then I just need to replace my clutch master and I think I am ready to roll!!! :twisted: :twisted: :twisted: :twisted:

I took my first short test drive this evening!!! The timing still sounds a bit too advanced, so I will retard it a bit more tomorrow. Other than that, it seemed ok for an eco-TDI. I'm thinking the boost line came off the boost gauge as it doesn't move at all, so the LDA probably wasn't adding any extra fuel. The bad thing is my clutch was slipping a bit when I gave it a good amount of throttle. It has done that in the past from a time or two it got some oil on it, so hopefully it will just burn off or something. If not, I guess I can get a puck type clutch disc for a BMW as it will fit with a little filing of the splines. I probably better put my front axle in as well as I got stuck in the snow in my driveway. :lol: It was hard to tell from such a short drive, but it did seem like it had more torque.

Fantastic work! I'm impressed.
I'd like to come down and see it when I have some time.

I could drive up there sometime. You KNOW I want to start driving it once all the little bugs are worked out. :lol:

Will do! :lol: I need to fix my minor problems first, so it probably won't be until later. Also don't forget that my pump setup isn't supposed to be that great as I haven't modified the control lever yet.

Here it is, though I'm not totally thrashing it. Too many dogs, kids , cars on my road to fly down it. For some reason, the idle speed is up quite a bit. I'm wondering if I hit the cold start as it has no cable on it and I put something back there to pry the pump out a little to change the timing. I should get one from outside to see what the smoke is like. I know there is a bit when shifting though.

:lol: :lol: :lol: You noticed. Yeah, I screwed it up when I was cleaning a bunch of crap out of it. At least the odometer works now though. Clutch is still slipping, but seems better

Did my first significant test drive today, about 65 miles of very mixed driving. About 20 of 30 mph road, 25 of stop and go city driving, and about 20 highway, mostly uphill with a head wind. Average of 27.5 mpg. That's close to the best(30) just highway mileage I ever got with a broken in engine. Also I don't think my fan ever came on as the temp never got high enough, which was the biggest problem with my old AAZ. EGT's did get to around 1300, which may be due to timing or the fact that for some reason my boost doesn't get as high. Maybe being more efficient, a TDI puts out less exhaust gas? I know the turbo can make it as the actuator got off center a little and boost got way higher, but the setup was the same I had on the AAZ. It made 18 where I had it set on the AAZ and only 10 on the TDI. I did put another spring in the actuator before the drive, which brought it up to 15 psi. Power seems decent, at least what the AAZ had from what I can tell with the slipping clutch.

Cool. So did you have to time the IP differently than the IDI?
Will this be an easy job for Giles (I think you said you were sending your pump to Giles?) to set-up? I am just wondering if this engine would just be treated like any 1Z. etc m-TDI or if he needs to have the engine for tuning? Does Giles even do m-TDI pumps?
