This was a message I sent to the list on Thursday, though it didn't go
through since it was down. I've talked to Loren a bit about my
problem, but I figured more brains on the problem couldn't hurt.
Hey everyone. So I got my diesel Rabbit tach all set up and working
using Roger Brown's optical pickup wheel design. It was beautiful. A
working rev counter in that old car. Talk about neat.
So I buttoned it all up and took it for a spin. It was working
perfectly, when all of a sudden, the tach went dead. I wondered what
the hell was going on, so I started to drive home. On the way home,
the car started to buck and kick. Soon, it would barely run. I
hobbled home, and killed the car. Smoke started pouring out the
tailpipe. Now I'm really nervous.
I pushed the car in the garage and took stock of the situation. The
front bolt on the timing belt cover had come undone. Because of that,
the cover tipped against the injection pump pulley wheel, taking the
tach optical sensor clean off. That explains why the tach died.
There was oil all over the outside of the valve cover. I hate those
stupid cork valve cover gaskets.
I'm hoping the sensor didn't go flying down into the lower belt
cover. Looks like I get to pull it apart and have a looksee. I'm
still not sure why the car was trying to die. that doesn't make much
I had the power for the tach converter hooked to the stop solenoid. I
figured the car was bucking because it was coming loose or something,
but when I popped the hood, all was tight.
It's times like these, I just wanna sell the car and make it someone
else's problem. I'll probably just let it sit for awhile, and then
have a look. What really makes me nervous, is the smoke smelled like
coolant. I've only got 4K miles on this head gasket. I was at around
4K rpm when the tach stopped working. With my luck, it blew something
So, anyway, there's my situation. My Rabbit is currently in the
garage, cooling off. After I cool off, I'll start pulling it apart
and try to find out what the hell happened. I'll keep everyone
A really bummed and pissed off Matt
I tried restarting the car the following day, and it would fire and
die over and over. It spewed lots of black smoke when it tried. So
far I've checked the timing which seemed off, so I'm in the middle of
trying to get that adjusted (thought it's being more of a pain than
normal.) Any other ideas?
