Have you done a compression check?

If thats ok, you timing might be off

 

I don't know how to do a compression check. Here is what it sounds like:

If the car was running within that past few days compression should not be an issue. I was thinking more like throttle, MAF or idle control valve.

Compression Test - Volvo S70 GLT, 1998

 

It was running great after the pcv system cleaning, right before I replaced the cam seals.

 

Either your timing is off or something is not connected

 

Are you sure you have spark? If you replaced the cam seals it's likely that the cam sensor connector is messed up and you're not getting spark.

 

That was my first thought too

 

I thought that first, but I checked it has strong spark. I have noticed as I messed with it that it takes three complete revs for the crank to bring the cams back to manufactures mark, so it appears that I could be off 1/3 or 2/3 on the timing.

This is what I am going to do: Pull the plug from cylinder #1 and insert a 12" piece of tube, then turn the crank till I find TDC, check the marks, and then do it twice more for the cycle. I must have it off by 1/3 or 2/3 but since this is an interference engine, I would think it would have given some indication of internal parts contact.

 

I found TDC on Cyl 1, and it did not line up with the timing mark on the crankshaft pulley. I removed a few more parts and am able to see the crank timing mark on the block and the area where the crank should be notched. It is not. I rotated it through tooth by tooth and took pics if looked possible that it was notched. It isn't notched at all.

What this means is that I have to assume the marks on the crank pulley are good and that I had it all aligned correctly. Now what?

(the pic is at the mark on the pulley)

 

There is some kind of mark on the crank. Either a knotch in the valley or one knotch of the two peaks on either side of the valley that TDC. When you found the piston all the way up, where was the crankshaft marks near the cover? Did you find those marks?

If you have spark, and fuel pressure, you have an air problem. Maybe your MAF is bad.

 

At TDC the mark on the crank pulley was off by about 15 degrees. There is no mark on the teeth of the crank gear. I checked it tooth by tooth.

 

I just noticed while I was staring at it WILLING it to work that without the belt on there is about 10 degrees of play on the intake cam. Is that normal?

 

Yes the cams can move with the belt off. That's why some people use a cam locking tool when they do the belt. Just make sure the cams and cam shaft are aligned before you get the belt on and crank it over by hand.

 

OK, I found the crank timing mark, got it aligned with the cams, and still nothing. Bought a compression test gauge, and checked it per the instructions, 0.0 on all cyls. I never heard a valve strike, but assume the worst. How hard is it to replace the valves?

 

You have to pull the head to get to the valves. Most people just send the head to a shop to be rebuilt. Average price is about 175 plus parts.

Did you crank it over by hand two full times with the belt on? Were the cams turning and stopped at their mark again?

 

Yes, I pulled it through each time, and got good alignment.

 

If you have zero compression something is bad wrong. You can drop some oil in the spark plug holes, about an ounce in each hole and see if you get any compression then. If not, you likely have some broken valves or a severly warped head.

 

Yeah, I figured the cylinders were washed, I oiled them before the check. Bent valves it is.

 

I just read back through this post and it seems that you were moving the crank without the belt on. That's not good. The only time I have ever turned the crank is when the belt was on and the crank and cams all turned together.

I'm not sure if you can hear valves break over the sound of the starter. Also, I have never heard anyone ever say they could hear stuff happen when they broke their valves with a bad timing belt.

Maybe you can find a scope with a light on it to look into the head through the spark plug holes.
