V6 Disaster
« on: 28 April 2009, 08:04:45 »

Well I finnally got her rebuild after finding the head gasket leaking.

Turned her over and she sounded fine, but still dragging fuel through. Turned her over again she fired and then died, again guessing dragging fuel through.

Turned her over once more there was a bang and a noise sounding like the a belt being dragged over a cog. Will now have to strip her down again.

Will be stripping down tonight (rain or shine) as its driving me scanny not knowing what went wrong.

I know all the valves were reseated properly after fitting the new seals and I know all the timing marks were correct thanks to the borrowed cam locking it. Also the tention appeared fine so I dont know. It cant be a seized crank as it was running fine before stripdown and I was able to turn to top dead centre before rebuild.

Like I said earlier the only thing I can think is if the belt has stripped its teeth or jumped its cog. Will let you all know  :-/

Dragging the fuel through is when the engine is being started for the first time after the fuel lines have been disconnected. This would be a little worse due to them being undone for over two weeks as fuel evaporates in the lines so has to pump from the tank.

oh i see, i was under the impression, rightly or wrongly, that if you leave the key in position 2, ignition on, for 5 seconds or so that the injectors would be primed and ready to go?

Just a thought. Def got the correct marks on the cams? I beleive there are 2 or 3...?

Commiserations Buddy, I do hope you havent suffered too much damage.
 I am in a similar boat to you at the moment, mine has skipped 4 teeth after a top end overhaul, and I am waiting on the loan of a locking kit to reset it
The suspense is killing me.

Well what lovely British Weather we have. Have removed timing belt cover to enable me to see whats happening underneath and the belt appears to be in position.

Awaiting my Brother arriving to have a look but doesnt sound good. As the belt is still in situe the next thing will be to strip everything back off the engine and check as we go along. The noise just sounds like something trying to turn over but jamming so wondering if a valves has bent but no way of checking without removing everything

The belt is still on but is the timing correct?

And is the belt tensioned correctly when set to TDC?
