Done more of these cambelts and top end v6 rebuilds than I care to remember - I will gladly take a trip over for the cost of fuel and a small contribution to my "fix the beemer" fund

JamesV6CDX I very much appreciate it it is now running after a mate of mine come over and give me a hand it was 180* out timing wise so started from scratch and although its running the best way i can discribe is it sounds like a diesel with the belt vibrating on top between the cams but is taught everywhere else  any ideas

Belt a tooth off at the top, remove it, position and retension it correctly.

Both marks lined up though is it ok to run

This were the marks after we turned it by hand

Without seeing it, id suggest rotating each cam half a tooth so you get one less belt tooth in between them, before you tension it.

Clear as mud, I fear

Is there a piece of crap stuck between the teeth in one of the cam pulleys?

Is the spring tensioner set correctly? I can't see the spring tensioner clearly enough to tell in your photo.

Did not see anything i dont think there was

I followed autodata to a t to tension belt! It only pulls back when at low speeds or pedal released

Should be impossible surely    Bit like saying the tyre is only flat at the bottom...  So unless the valves are clipping the piston... ?

Long and the short, it isn't timed properly. Does the cam lock fit in the cams when the crank is set correctly?

We are in talks now guys and looks like JamesV6CDX will be over to help sort it tuesday TO WORK HIS MAGIC

[Bigron]

You will never regret it - James is ACE! How do I know? He did mine and his attention to detail is beyond reproach; he's a great bloke, too.
James, if you happen to read this, TAKE IT EASY!

Yeah, looking at that picture, the left cam looks like the mark is in line with the timing mark on the block, but it shouldn't, because the camera is not bang in front of the cam. I would say that the cam should be half a tooth anti clockwise.

This would also explain the slop in the belt between the cams. My guess is the tensioner isn't set correctly to pull the slop out.

Glad you have James coming over. By all accounts he's a mechanical whizz and a top guy to boot.

Makes no sense to me squire... the belt pulls the sprockets round not t'other way round. If the belt ain't moderately tight it don't pull the sprocket.
