I would say it was coughing and sputtering because it had already skipped before he bought it. There is some reason it was sold by po not running.

I thought that when the marks on the cam gear(washer) and the cam bearing tower were aligned the dampner degree should be at 0 (TDC). I think the 24 degrees BTDC it the IP pump timing (with one of the timing methods).

That car is aproching 200,000 miles. I have some chain stretch so the dampner is not at TDC. The main pint is that if he jumped a tooth it is going to be way off. One of the post said 1 tooth off= 16 degrees.

Also to cover myself on this I suggested he look in his manual to be sure about the dampner marks.
In fact no matter who gives you advice it is always a good idea to use that information as a guide and find out for your self. I have found from past experience that even professional mechanics when they give advice often forget to tell you something or get something out of order.
It is sort of like I can drive all over my town (been there since 1977) and go where I want to go but if someone ask me for directions to such and such of street is I often cannot tell the as I do not look at the street signs anymore.

OOPs Yes, I jumped to IP timing, TDC for the cam. The 24 degree mark on the balancer for pump timing.

Now I'm not so sure it jumped time...

Here are the new clues:

1) I pulled the valve cover again and there is a valve that is approaching full lift. I loosened up the adjustment nut on this valve and one other that was just past full lift with no change in the locked up state of the engine.

2) If any valve were hitting a piston I would think it is the one nearing full lift, however I can easily turn the cam in the direction of normal rotation using the bolt on the end of the cam, thus further opening this valve.


Could the IP or vacuum pump have locked up thus holding up the chain and therefore the crank shaft?

I would pull the tensioner at this point, then you might be able too tell if the chain is hanging things up or the crank/valves end of things.

I'm not sure I'm willing to put that much time into this car...it may be destined for the scrapper.

The vacuum pump is easy to pull off.
