Title: Engine rattle on start
Post by: Ceptor on 24 February 2004, 09:24
Can anyone help me with a new and annoying problem? I've done a search but couldn't find anything similar.

My engine is the 1.6 carb and on start from cold there is a loud rattle from the left (o/s) of the engine which dies away after a few minutes - although it's still there but quieter.

Could it be the cam belt? I know it needs changing soon anyway - 100,000 miles on the original.

Do you mean the timing belt end?
Could be the tensioner, try taking the cover off, and have a listen.
If it is then get it done straight away.

Yes it is the timing belt end, there is quite a loud non metallic rattle from that area on cold start which then dies off after say one minute.
I'll have a look asap. If it is the timing belt what should I replace in addition to the belt and tensioner? What special tools will I need?

change the timing belt,tensioner and v belt.
no special tools are required, however it is a lot easier to tension the belt with the proper vw tensioning tool.

Thanks. I will also be doing the timing belt on my 1984 Audi 100 5-cylinder engine soon can you recommend a similar website I could read which covers the Audi range?

I think the 5 cylinder Audi engines, have the timing belt on the water pump type, same as early smaller engine golfs and polos, ie. 1.0 and 1.3.

Ah yes I see that now.

The descriptions in the Haynes manuals look very similar. I was just hoping that I could change the Audi timing belt without having to remove the vibration damper on the end of the crankshaft, fitted with 258 lb ft...

The vibration damper is not fitted to that torque, thats the crankshaft bolt. The vibration damper (or pulley) should come off with the smaller allen key bolts, same as a golf.

I've now bought the bits necessary to do the cambelt job on the Golf. I now have the timing belt tool mail order at ?14 and the VAG parts;

Belt                ?10.80
Tensioner       ?24.78
 
Socket head cap
screws x 7             ?1

All VAG are plus VAT came to ?43.04.

When the snow melts I'll have a crack and let you know what happens.

Well the snow has melted so I changed the timing belt today. Never done one before but having checked this and other sites for info I felt ready for it!

I previously soaked the pulley bolts in wd40 so they came off easily,  however the centre hex head screw holding on the plastic lower timing belt cover rounded off so I had to drill that out.

The belt was quite loose and the tensioner was stiff to turn in a couple of places once it was off although the belt didn't seem in danger of failure anytime soon but it may have been more elastic than it ought to have been.

Of course the pulleys moved while I was trying to get the new belt on and the car was difficult to start at first. After checking I found that I hadn't positioned the intermediate shaft sprocket correctly and also that I was one tooth out on the crank. I was not lining the flywheel up right either, I was using a notch when I should have been lining up the pointer with the small 'o' (they are both next to each other - say 1" apart.)

All told took about 3 hours but was easier than I'd thought, the nice weather did help alot!

I checked the car tonight and the annoying rattle has gone and the car even feels more zippy so all in all a pleasing result.
