I built that better VNT15 controller. Using the stock Vnt-15 controller spring reversed so it would be controlled by boost instead of the computer controlled vacuum it came with. Took it out for a test run. It worked perfect 1st gear the boost hit 15 - 18 and the EGTs popped up to 1200 and stayed th...

It never overheated.
The temp gauge sat perfect in the center.
The whole time it was overpressure.

I didn't take it into town today.
A couple more trips out of town a ways and back
before I try that.

Got it all back together. Put some used antifreeze in it because of the cold weather coming,.. and I don't think water in the block is good for it, might cause corrosion. Started it up and it was still missing on one cylinder,.. for awhile. I really hated that truck for awhile but it smoothed out. I...

Got the head off. Everything looks fine. I stuck a little LED on a wire in the coolant passages to see where it shines, compared to a good head. I'm still going to see if my buddy has an endoscope that's thin enough. Then I'm going to put this head back on, with the felpro gasket and this time I'm n...

I just bought 3 red speedometer cable gears from Hans. For the couple ACN tranys I've collected I stuck one in the Rabbit but have no speedometer. The more I think about it the more sense it makes that the #4 cylinder would be the one to get hot. It's the last place in the engine for the water to go...

Lot's of people slam hans's parts but I've bought stuff from him before that was good. The holes around the 4th cylinder on that gasket are small too. So far the Felpro gasket is the only one I've seen with big coolant holes near the 3rd and forth cylinders. I've noticed the 2-notch shortage also,.....

Maybe all head gaskets aren't created equal. Here's a link to the last head gasket I used: https://www.rockauto.com/en/moreinfo.php?pk=11064036&cc=1285455&pt=5412&jsn=452 It's made by Ajusa. Here's one made by fel pro: https://www.rockauto.com/en/moreinfo.php?pk=122367&cc=1285455&...

Here's some pics of the newer Rabbit VNT-15 controller. The last one I posted/built was still a prototype. It worked great but the holes wallowed out. So for the new ones I use small sealed bearings. This picture gives an idea of how the bearings were mounted: https://live.staticflickr.com/65535/515...

I've seen something similar when the small line to the reservoir is blocked.
It traps air in the head because it can't get to the high point of the reservoir.
Probably why I'm thinking that way this time.

The threads on those 11mm bolts are pretty fine though. That effects the torque. So an update on the little red pickup. Something is wrong. Not sure I mentioned this. Didn't think too much of it the first time I took it for a drive. After a short drive for a few miles and coming back I would hear th...

The parts arrived from fcpeuro, faster than they said. Had it running but the fuel lines to/from the tank were leaking. I forgot there was a fuel line that was about 12mm on one end and 8mm on the other. A tapered fuel line. Fortunately I had remembered that for the Rabbit's it's the same. ...and I ...

Yeah, romping on it too hard when it's cold isn't good for any engine. I don't think I beat it too bad when it was cold. did make sure it was under load or backing off. The fuel lines are dripping as they come from the tank. So those need replaced. I noticed no anti-rattle clips on the brakes last t...

So the little red pickup came back because of oil in the coolant. I got the head back off and it looks like maybe it leaked under the head gasket into the cooling hole very close to the bolt hole the oil pressure passes through on the way to the head. Like the o-ring failed. That's a first. The only...

I updated my signature.
Also was working on something,
looked up and there was a 3-outlet hose.
Get ahold of me and we'll figure out how to get it to you.
