noise 82 vanagon diesel - timing?
I've got a noise that sounds like rattling as I rev it up. I thought maybe some of the valves were loose - they're not. I'm thinking it must be timing - sounds a little "tinny" like when the timing is off ... but I've checked it again and it is ok. I've redone the injector timing with a dial indicator also. It does this as I start to rev it up; then it goes away. Again, a metalic, rattley, noise from the engine. This started after I did some work to repair the crank pulley which had gotten loose and wobbly. The groove on my flywheel is a "v"-shaped notch and I believe that is what I timed it to in the past. Any ideas?
Hi daves, does it make the same sound when you keep the clutch pedal down( tranny in first gear) and rev it up, sometimes when the radial springs in your clutch plate are worn and loose, you can hear them rattle.
If it still rattles, it's something else. Is your timing belt too loose?
Yea, the V notch in your flywheel is the right one.

ok, it's solved
thanks to you that tried to help. I did three things and one or more of them solved it. I think it was a timing thing. I tightened the timing belt because it was a little too loose. I put in some thicker cam disc valve adjusters for those that were on the loose end of tolerance. and finally I readjusted the timing of the fuel injector pump with a dial indicator again - it may have been off. It sounds good, now, and runs well. thanks again, to those who took the time to answer. Dave

mine did the exact same thing but it was due to the timing belt coming loose (tensioner?)
one cold day -15 i started her up and she jump a tooth on the cam started making this rattling sound in one of the cylinders. i was getting poor take-offs / power but once the turbo kicked in she took off like there was no tomorrow. after re-timing it she sounds better then ever and takes off better then ever.. i wrote a tread about here called "pussy diesel". now after 2-3 month i found my self in the same position but lacking the pussy side. did my belt actualy streach or did the tentioner finaly give out.. this tensioner is different then the conventional tenssioners i'm use to. it almost like its spring loaded or sometime.. i tryed playing with it to see if its springy but couldn't make it works.. so i thought its just another tenssioner. time to go buy a tenssioner and belt before i'm really lucked out with a 235KG paper weight
