- Silver 2003 Jetta TDI, Silver 2000 Jetta TDI (sold), '84 Vanagon with '02 ALH engine
Ah, sharing this event that occurred this morning.
This is the ALH engine in my 84 Vanagon with about 50k miles on the TB job and a total of 201k miles on the engine (about 72k miles in the Vanagon).
So, to commence the story I must back up about two months ago when I heard a squeak/chirp and thought it was the top small roller between the Cam and IP Sprockets. So, I changed that roller and still had a squeak/chirp. Considering my bad hearing, I just assumed the noise was the back of the belt chirping on that small roller. And, for what it's worth, I've only driven this Van about 1500 miles since last July after completing a 12k mile trip to Alaska and return.
Now, fast forward to this morning. I was heading into town about 15 miles away to pickup a few items at the local hardware. A friend that lives nearby needed a ride to pick-up his car at a local shop. So, when I hit the main road I blew-out the soot for about 9 miles cruising at 70 mph and more. As I slowed for the drop-off place for my friend I heard this horrible sound from the engine and began to smell anti-freeze.
After quickly observing gauges, I immediately shut-down the engine. I had it towed to my uncle's garage which fortunately was close by.
It appears the TB "did not" jump time ....... thus, I dodged the bullet. However, this is still sort of preliminary as I have not 100% confirmed everything.
So, below are a few pics of the results (comments are at the top)
Below, you are looking down at the shredded TB at the Tensioner...
Below, is a close-up of the shredded TB at the Tensioner..
Below, you are looking at all the shredded TB bits soaked with the pink anti-freeze.
Below, the crankshaft locking device appears to be in the "normal" postion based on obvious wear where the two bolts go thru the slots... Thus, with the Lobes of the Cam on #1 in the proper up position (10 and 2) and the Pin in the IP, it appears to be in Time. (read more at the next pic)...
Below, from the files, is a pic of the G60 Fly Wheel showing the TDC mark which I made. This G60 Fly Wheel was installed before the TB job. The TDC mark on the OE 1.6 Diesel Fly Wheel was very visible. My added TDC mark on the G60 Fly Wheel doesn't show in the observation hole. But, the pointer is aligned between two teeth and adjacent to the bolt you can see. So, I do believe the TB did not jump time. (I have removed the Valve Cover but not the Vacuum Pump to install the lock plate.)
...............
The Water Pump is locked solid. It was very difficult to rotate the engine to set-up TDC. I could see and feel the TB jumping the teeth across the locked-up Water Pump cog.
This really sucks because, as I stated above, the TB job has just a little over 50k miles on. Also, if I had not been dropping my friend off, the next mile or less would have been the demise of the engine!
I'll get back to the job Monday morning...
