phantom knock

[timthetinyhorse 0]

time for my 1st tale of woe,

did a 200 mile round trip on saturday and the c was running fine, its a 2l 16v btw, come to start her sunday night and we have a nice knocking sound from the engine, worried about the seriousness of this i turned off the engine, monday morning i phoned the local vw specialist (volksentre in blyth) for advice, they told me not to run it an that they would come out for a look, they have just been and its a funny one, the oil pressure is fine and the car is running fine with no hickups or anything, so the first step is to get the timing checked to make certain that the belt hasnt slipped causing the piston to tap the valve then after that is a good old engine stripdown, anyone else had this problem before?? the guys recon the noise dont sound terminal but its still a concern and the dont recomend i use it, any advice would be great,

thanks

and it's definitely an engine noise and can't be anything else?

 

if so, it could well be one of the many bearings on the crank shaft including the thrusts or maybe even the end floats?

yeh deffo an engine noise mate, guys who came down are vw specialists, dont sopose anyone had a drawing/photo of the timing marks they could send me so i can check the belt hasnt/has sliped?? if not looks like the head is coming off.

there should be some on here somewhere, try the search.

 

if you have any more information about how and when the noise happens, engine temp, under load or idling etc etc etc.

Here you go mate

[timthetinyhorse 0]

happens as soon as you start the car and dont change once the engine reaches temp, so basicly its there all the time, going to check compresion and timing tomorow if i get time, after that going to look at cam shaft bearings, the one thing that makes me belive its the timing is that it was fine when i parked it opne day then started banging the next time i started it so thought the bely may have slipped during starting the engine

IIRC, the cams don't have bearings? I think that's right...

Yup, defo no bearings on the cams :)

 

When was the cam-belt last changed?

[timthetinyhorse 0]

cambelt was done just before i bought it, was thinking perhaps its not been tensioned properly?? aint had a chance to take a look yet though so still no further forward
