Title: 1.8t warning lights,wont start......timing belt gone =0(
Post by: yickergti on 10 June 2012, 12:15

Had a text off my brother this morning saying his his golf wouldn't start last night. He said it was running fine before he parked it up.

Said he tried it 3 times and the 3rd time it flashed up "oil pressure,stop motor" so just left it. Does this sound like the common sludge/pick up pipe problem and would replacement oil pump and pipes cleaned be a good place to start?

Any help would be appreciated

I would have thought it would still start though if it was just a blocked pipe and then cut out? But then if its the sensor maybe not  :undecided:

Well just had the neighbor look at the car and he says the timing belt has gone. Probably slipped its teeth at the bottom  :shocked:
Anyone had this happen to them and if so have an idea of the costs involved? Car wasn't running when its happened so hopefully there isn't much damage.

The belt won't have gone with the engine off. You'll have to whip the head off to assess the damage.

+1

could be any amount of damage... only real way to find out though is to take it apart and have a look...

Is there no other way of assessing for damage apart from taking the head off?

A compression test will confirm the worst. You will need to fit a new belt first for this.

how did your neighbour come to this conclusion?

I dont see how the cambelt has snapped parked up overnight, youd have known if it had gone when driving and you say it was fine. I reckon its something else personally from what youve said

The belt hasn't snapped,he said he recons its slipped. There is just no resistance when turning over the engine  :undecided: will try and have a belt kit put on it today and see what happens before i start ripping it apart

He recons its gone because the pulleys/belt aren't moving when the engine is turning over. Having someone do a compression test on it tomorrow so will know more then

Hydraulic tensioner may have failed?  :sad:

Well,had someone else have a look at the car today. When he 1st tried it he said "that doesn't sound like the belt has slipped". He took the belt cover off,tried it again and then changed his mind because he says the top pulley isn't moving and the bottom 1 is spinning. 
Can anyone recommend a head re-builder,preferably in the north west  :cry:

I wouldnt think it would turn over if the belt had snapped .My ford didnt ,pistons hit valves and wouldnt turn over.My uncle got his to turn over  :rolleyes: but it smashed his cam shalft to pieces. I would strip the head and see whats happened.

if top isnt spinning but bottom is it will be the cambelt which has slipped, water pump could have gone which is common, or Hydraulic tensioner, it will have gone once hes either turned it off once it was slowing down or when he tryed starting it, if pistons have hit valves they make a right mess on 1.8ts gonna be easyer to throw another engine in id say! could be lucky though
