well, finally got the front of engine all together again. started first kick, which is a bonus, and sounds nice except for the whining timing belt

what stops the timing belt coming forward onto the back of the oil pump pulley? cause thats what appears to be happening. i've tried re-tensioning it a few times (using the 90 degree twist method), and pushing it back to the back of the pulleys, but it always comes forward within a minute or so and starts whining. am i missing something? i really need to get this car going cause the one car thing really isn't working at the moment


cheers all

Are you missing a washer maybe.. the 90 degree twist
method works good maybe you should still back off on the
tension-er to get the noise to dissipate. Good-luck

Replace the tensioner. As the bearings in it start to go and it binds a little, it causes the belt to walk. Ours did this and I scratched my head over it for a while. Changing the tensioner fixed it.

+1 for what Slam said plus the belt whining is usually due to it being set a little on the tight side. Back it off a fraction.

The timing belt tensioner pulley is an inexpensive part shared with 1.7 and 1.8L watercooled VW engines. They cost less than $20. Here is the States I can order a Bilstein Kit with the belt and tensioner pulley for $20. Make sure that you get a tensioner pulley tool (cost is about $10-$15) when you get the pulley from your local VW Specialist. You will also need a "shorter" bolt, and a washer to convert to the VW tensioner. Porsche superceeded the tensioner pulley to the VW part many years ago.

[Mike924]

Shorter bolt, surely, Gohim.

The VW part doesn't have the hex adjuster and is therefore 3/8", 10 mm shorter than the Porsche part and, so, requires a shorter bolt.

Oops, am I bad ????

Okay, I fixed my Boo-Boo, and a spelling typo at the same time.

At least I remembered you need to replace the bolt.

[steeny]

thanks guys, i'll chase up the new tensioner and belt. any chance you know an actual model and year from which the VW part that will work?

is there any benefit changing the cam pulley and the oil pump pulley while i'm at it? are these simply VW items as well?

cheers again

In Aus, the best price I've found so far for the timing belt & tensioner is $62.15 from Mick Motors, a VW Parts Specialist in Brisbane. Postage to me (I'm in Queensland as well) was $7.00.

I just gave them the part numbers (026 109 243E - Timing Belt Tensioner & 056 109 119A - Timing Belt) & they were able to give me the prices.

The company that I use here in the U.S. for many parts is named "StopShopAndDrive.com". I get most Porsche and VW parts overnight, and shipping within the Lower 48 States is Free for orders over $50.

They show parts by the brand and manufacturer, so you pick the quality and price of the part.

Some of the prices that they offer for grease, oil, and brake calipers are unbelievable when compared to Dealer prices, and the quality has been very good. In over three years now, I haven't sent anything back.

I have been buying parts for a 86 VW Jetta that I am restoring, and I have paid about $2 for Genuine ATE caliper seal kits, TRW Brake rotors, and $1 for wheel grease seals and fuel injector o-rings.

At this time, they show the tensioner pulley by SKF and GMB, both at a little over $15. The Timing Belt is Continental for $7.84, and a Continental Kit with the timing belt and tensioner pulley is $28.

At this time, they don't ship out of the U.S. You might be able to order, pay by credit card, and have them ship the parts to me. Then, all I would have to do is drive down the the Post Office, and drop the box off (you would have to send me the payment for the shipping). this might work for you if you can't find a decent price over there.

Or, if you send me the money for the parts, and the shipping, I can order the parts, and ship them to you by USPS. I suggest that you don't buy anything heavy unless the price difference is very high, because the shipping will not be cheap. Think light weight, and high saving over buying locally, for items that you would order. Or parts that you can't find at all over there.

The StopShopAndDrive Website gives you the net weight of the parts, so you can get an idea of what the shipping weight would be (1-2 pounds for the box), then go to the USPS Website, and use the shipping calculator to give out the cost of shipping from my place to yours. You would only need the US Zip Code of the shipping location (mine is 92376), and your complete address, along with the weight of the package and the dimensions to determine the cost of shipping.

i'm gonna try a local bearings and pulley place tomorrow and see what they say, otherwise, theres a local VW dealer just a few suburbs away.

if i hit expensive parts, or other probs, i'll keep you in mind gohim

cheers for all the info
