What Mike said, except the on top part. It goes on top of the pan if the engine is upside down, so really it goes on after the pan to spread the bolt load.

 

And don't over tighten the 6mm bolts holding the pan on or the gasket will squish out. As a matter of fact, I like to ditch the gasket altogether in favor of a nice bead of "The Right Stuff" RTV.

Probably cavitation. Check that the bottom rad hose is not soft. Rev the engine to highway speeds and watch to see if it collapses from the suction. Also check to see if the vertical tubes in the rad are crusty with scale deposits. Both these things will resist and slow the water passing through the pump. When the pump impellers spin they can cause cavitation which will erode the pump hollow in the timing cover. If the coolant moves at or close to the speed of the impellers this is much reduced. Always run antifreeze coolant.

 

 

Almost forgot... make sure the thermostat opens fully and is not a restriction.

The motor has been turned over several times since I liked up the chain timing marks. When I torqued the cam bolt the motor turned a little and if I turned it back it would have messed up the chain tension on one side so, is my issue because the chain marks are not liked up? The motor is at TDC compression stroke at #1

I'll give you the short answer and datzenmike or hainz can finish...

 

As long as the crank is at tdc on the number one compression stroke and the cam timing marks are lined up you'll be fine...

As far as the dizzy.... as long as the rotor is pointing to a plug wire that becomes number one on the firing order.. .

The only way I can get the distributor drive spindle to match the cap is to have it at a 1:35 ish position, I can not get the 11:25 to match the cap even though I put the timing chain on correctly.

This statement is a little off.... the timing chain technically won't have an effect on the oil drive spindle..

The oil pump/ dizzy drive spindle is driven off the crank gear...

 

Again if the crank is a tdc it honestly doesn't matter where the rotor points as long as it points to a plug wire and that becomes number 1....

The 11:25 is where it should be but doesn't have to be....

Correct, timing chain has no effect on distributor timing. It should still be at 11:28. Is the advance mechanism jammed or the vacuum advance? The plate under the rotor should turn clockwise when turned by hand and return by itself. If you suck on the vacuum advance hose to the distributor, it should also move the plate clockwise.

if motor is timed at TDC on crank Zero position then you install the oil pump drive to the 1128 position. in post 92 it needs to go more clockwise a little bit.

then install the  distributor till it close to 1128.and loosen up the timming plate that bolts to the dist underneath and see if you can dial it in to TDC .

 

maybe you got a wrong distributor mount but if this was stock it should all match up.

 

 

I assume your putting the oil pump drive in wrong.

 

but if it works where you have it and when running you gat 0-20 degs with a timming light when you turn the dist just call it good
