Please Read Timing Belt Came through cover - Page 3

I like when people say "The bolt must have backed out.", like it was a voluntary action as if it robbed a liquor store with a gun.

I never touched it. I wish I had so I could explain why this would happen almost 4k miles after the timing belt change.

did you buy the car brand new?

is that the cars first timing belt job?

have you had a shop remove the balance shafts?

when you were doing the belt did you put a wrench on that sprocket to put its timing mark in place after the belt had some tension on it?

Those nuts are very tight, I doubt you could even loosen it by using it to rotate the belt.

I have NEVER seen one of these nuts back off if it has never been tampered with. Eddies questions are extremely valid in this situation.

DSM's used to dump this nut with some frequency. So, I suspect there is no owner contribution to this problem. It is just an old known problem and bad luck.

I've been driving, racing, and wrenching on DSM's for 10 years now and never heard of this nut backing off. I have about 200,000 miles of daily driving either a 1g or evo and again never had this issue you speak of. When you combine all my friends with 1g's, 2g's, and evo's that I help work on(probably another 500,000 plus miles) and again we have never seen this "problem".

Just saying.......

I'm with 0x ^^ Never once heard of this. No system is perfect. Maybe it was under torqued from the factory.

Sorry to hear about your misfortune. I would rebuild the engine yourself, FWIW.

i've never seen this happen on its own either. only time i ever saw something like this happen was on a honda timing belt that i did, i completely and entirely forgot to tighten the crank bolt for the crank pulley. so the pulley came off. luckily it was just the accessory one. or the crank damper.

I was a member of the Talon Digest and later DSMtalk. Between them I’m guessing they had 14,000 members. On both forums the oil pump sprocket nut coming off was a common topic. The consensuses advice then was to remove the nut at belt time, check its condition, and retorque to 55 ft lbs (the required torque for a DSM). So, it was hardly an unheard of problem.

I wanted to go on record that I skimmed this when I originally posted and was in the mdst or reading other tbelt threads, and missed that the oil pump gear fell off..

All though I still think that strange things seem to happen more with some of the aftermarket belts.

have you had a shop remove the balance shafts? No balance shafts are in place with a blue gates belt on them.

when you were doing the belt did you put a wrench on that sprocket to put its timing mark in place after the belt had some tension on it? I had to rotate (from the crank) 3 x to get all of the timing marks lined up properly.

Thanks for all of the responses guys. This actually is worse I have a interlock on my car which is the only reason I am able to drive so I guess I have to find some way to install in my other car for now.... This really sucks financially I can't afford a new motor or to rebuild but I might not have any choice in the matter.
