Thread: 300tdi hard to turn over

Sounds like timing belt has let go or jumped a few teeth.

And forcing it to turn over can damage valves and or rocker gear and push rods

Take the auxilliary belt off and try again first....

Thanks for these suggestions. Will pass them on as we’re quite a few km apart.

Could then turn it clockwise with a lot of effort, nothing came out of holes, but it wouldn’t turn anticlockwise,the way it runs

Hmm, which TDi, or any internal combustion engine for that matter, runs anticlockwise?

I suppose it depends on whether you are looking from the front or looking from the back.

The model aeroplane engines I had as a child used to run anti-clockwise looking from the front.

Aulro to the rescue again!
Many thanks to those who responded. My son dropped the auxiliary belts off and it turned over fine; culprit was a seized alternator. New one on its way from Mario, so his D1 should soon be ready for another 400 thousand km and a few more adventures.
Thanks again everyone.

Well, the OP has posted that he tried with a breaker bar on the front of the engine. As this is a car related forum I assume that it is about cars, and the conventional wisdom is from the front where in days of yore an engine would be hand cranked from the "front" in a clockwise direction.

Now if it was a twin engine aeroplane, then yes, one could be rotating in the opposite direction to the other.
