Car Forum / Driving, Maintenance, Tuning / General Car Topics / February 2007Broken Timing Belt
Hey.I have a 1999 Audi A4 Quattro 1.8L. My timing belt just broke yesterday and the car is now at a mechanic. (I refused to take it to the dealer because they have totally ripped me off in the past). The mechanic was telling me that they are going to replace the timing belt first so that they can see if the valves are messed up. I was wondering, if they are messed up, would it be safe to drive the car. I have been reading about how pricey it is to fix broken valves and the Kelly Blue Book estimate for the worth of the car is only about 6k dollars. So if its going to be a lot of money, it's probably not worth it for me to spend on repairs. Please share your knowledge with me!! > Hey.I have a 1999 Audi A4 Quattro 1.8L. > My timing belt just broke yesterday and the car is now at a mechanic.

Simply, the engine won't work. > I have been reading about how pricey it is to fix broken valves > and the Kelly Blue Book estimate for the worth of the car is only > about 6k dollars.

It is worth it to spend on the repairs. > Please share your knowledge with me!!

First: When your mechanic used the phrase "messed up" about the valves, he was being gentle. The common consequence of pistons hitting valves because the timing belt has broken is: Engine is destroyed. How much is a new engine or complete rebuild for your vehicle? Less or more than the dealer (who ripped you off by demanding you replace the timing belt at the recommended milage) wanted for that "unnecessary" timing belt? USW. Second: It is ***POSSIBLE*** that your specific engine is a "non- interference" design. Meaning: Pistons cannot hit valves when the camshaft is not rotating. Research the situation before you make any decisions regarding the repair. Or the veracity of your "mechanic." Third: We all hope your "mechanic" truely understands how to correctly time the camshaft after the belt replacement. Finally: I'll never understand why it is possible to obtain a driving license without demonstrating an understanding of how the machine works and why it works that way. > On Jan 30, 3:34 pm, ninamariarodrig...@gmail.com wrote: >> Hey.I have a 1999 Audi A4 Quattro 1.8L.

We don't know what the dealer did to have the OP believe he was ripped off. > Second: It is ***POSSIBLE*** that your specific engine is a "non- > interference" design.

One easy test: If the engine doesn't turn over, it probably is not turning over because the pistons are hitting the valves. The mechanic should be able to determine if it is a non-interference engine without replacing the timing belt. It should be in the manuals. Here is one place that says they have interference engines: http://www.blauparts.com/audi_vw_timing_belt_kits/audi_a6_v6_30v_timing_belt_kit _improved.shtml And I think these pictures has valves from a 1.8t engine from an Audi: http://www.audiworld.com/tech/eng23.shtml Hint: the valves are supposed to be strait, not bent. I don't know if this is the same engine you have. Good luck. > Third: We all hope your "mechanic" truely understands how to > correctly time the camshaft after the belt replacement. > > Finally: I'll never understand why it is possible to obtain a driving > license without demonstrating an understanding of how the machine > works and why it works that way. Because there is nothing most people can do except check the oil and other fluids in the new cars. I mean changing the plus in my 97 Contour is a major PITA. There is nothing else I can really change (well, I can change the air filter). I mean how many people who use computers can explain how they work? Plus, it keeps mechanics employed. Jeff
