I will keep this as brief and simple as possible. A coworkers father in law has a '99 Eldo (not sure which engine). Had a lifter tick. Been diagnosed as a "bad cam" by a Fla. dealer. Not sure how they came by this diagnosis. Bottom line is that they say that the cam is no longer available and has to be specially made. I'm raising the flag. :bsflag: What say you?

Can you get the last 8 of the VIN? Post something for Luke in the our vendor area if you can.

I do know GM lost a lot of suppliers recently (at least I heard that) so if stock was depleted it is possible.
Seems pretty unlikely but you never know.

Probably with some effort Bill. Car is in Fla. It just does not sound logical to me. The Northstar is still being manufactured. I was smelling a rat.

They change the cam grinds from year to year. Plus you get two or three versions of it each year.
Is the engine the original?
The VIN is the only way to know for sure if the cam is still available or not.
Luke can look it up and find out if anyone has one in the GM system. He can check dealer inventory all over the country I think.

Now THAT is interesting. I never would have guessed.

I suspect that the engine is original and I would think that the dealer that has it can check the system as well.

I would think that about the other dealer too, but sometimes parts guys get lazy and they won't search nationally or see if there are other sources they can get parts from.
It may well be there is no stock available.
You need a good parts guy to check... like Luke ;)

I don't know for a fact the grinds change, but I am pretty sure they do based on horsepower and other options from year to year.

You can still get all of them. The # on the cam is NFG. The # on the tube in my other hand is good. I just have one as a demo. The part # for the left bank Exh is 1647441 That is the cam that fails the most and it fits both cady engines.
