So it may actually be back in time now

Seriously though, sounds like you need the new timing set. And from here on, clockwise only. Counterclockwise makes it difficult for the tensioner to do it's job.

 

Ask me how I know that it skips teeth when you turn it anti-clockwise.

I the chain cover is off when you do it you can see that the guides are setup to keep the chain only in the clockwise direction; They act like a ratchet in the other direction.

 

I had not turned the motor counter clockwise except to find TDC. Here is a photo of the chain before I removed it showing the slack at the top.

Chain is replaced (both chains are replaced actually) and I will button it back up on Sunday. I will give an update when it runs.

 

Looks like the tensioner and or the stationary guide are having problems!

 

To say the least

 

Here is a couple shots with the new chains installed. When I compared the length of the new and the old timing chain, the old chain was about 1/4" - 3/8" longer! That thing had stretched over the years. I have started the car and it sounds great. I will finish buttoning it up today and take it for a drive.

Thanks for your help with everything.

 

Beauty eh!

 

Also, with age the guides get brittle and starting breaking off the guides.

 

So it is back on the road and running great. The boost is back to normal so the over boost was obviously related to the timing chain. I had one issue with an oil leak. While installing the valve cover, I caught the new valve cover gasket on the end of the exhaust camshaft but didn't know it. Tightened it all down and away I went. It was a good oil leak in that it was easy to find. Took the cover off only to find a bout a 1" piece of the gasket torn off and sitting in the top of the head. I installed a new one more carefully and now I am good to go.

Thanks for your help with this. I will tell you this is not a job for the feint of heart but immensely satisfying.

 

Drive on ! Enjoy!
