aespillers

First off, thanks for any input.

I replaced rotor, distribution cap and wires; no start. Went through everything up to the obviously cannot be; the rotor. I removed the dc and rotor. The incorrect rotor supplied to me had collided with the metal contacts on the dc so hard; it gouged a slice through each contact.

I went back to auto parts store, got new parts. No start. I have my previously running truck towed to the mechanic and diagnosis: timing chain skipped. $475.

I contact said auto parts dealer; they deny this could happen. It is impossible that the rotor could cause this.

Ok my questions to the forum:

1. Has this ever happened to anyone before?
2. Does anyone know where I could find data on the force generated by the rotor and the force necessary to skip a timing chain.
3. Case law regarding auto part store negligence
4. Suggestion re getting remedy for this.

As an aside, I had to put my Porsche 928 into service. Great gas mileage (right) and extremely reliable (no). It showed its opinion of this by killing a headlight relay. Another $100, still waiting for delivery and can only drive during the day.

i find it hard to believe that would cause the timing chain to jump a tooth, but MAYBE the distributor jumped a tooth or two. try pulling it out and turning it a tooth in the OPPOSITE direction that the rotor turns when the truck is running. also, the gear on the distributor is designed to wear out before the gear inside the engine, so maybe you just sheared all or some of the teeth off. take the cap off and have somebody turn the key. see if the rotor even turns.

Well for a timing chain to skipped there had to be one or more of these problems:

1: Hydraulic chain tensioner problem
2: Worn sprocket(s)
3: Worn oil pump
4: Worn cam bearing
5: Worn crank bearing
6: Stretched chain

As for a plastic rotor stopping the distributor shaft is very unlikly. Unless plastic fell down into the engine and jammed between the sprocket and chain. This may cause the chain to rise over the sprocket and slip?

So for $475 what is going to be done?

OBTW

This is impossible:

"try pulling it out and turning it a tooth in the OPPOSITE direction that the rotor turns when the truck is running."

If the truck is running then the distributer is not off by a tooth. If your distributer shaft is disingaged from the engine while the engine is running, your engine will die.

I'm very sure he meant for aespillers to turn the dist a tooth in the opposite direction the rotor would normally turn when the engine would be running; not while it was running

yup, thats what i meant, but i see how it sounded confusing the way i worded it. i guess i should have said turn it a tooth in the opposite direction that it would normally turn IF running.

Dude,

I was going to blast you for your litigious attitude towards the minimum wage parts store person, but decided it wasn't worth it.

Your truck has many, many miles on it (267,000), so the timing chain, chain guides and chain tensioner are well beyond their prime. You can probably chalk this up to mechanical failure from excessive wear (high miles).

I feel sorry for you being faced with a $500.00 bill.

Shit, If he had said he had that many miles on it I would have probably chalked it up to old age too. It may be a Nissan, but some parts will still wear out. The chain is probably loose as a 30 year career whore, and that little jar may have caused it to skip.
