So I finish the current repairs to where the chain is back in place, then do the front seal?
A quick look in the manual has me worried about that job. Now I'm also worried that the oil on the back of the block and transmission could be the rear seal. Should I stop now before I spend anymore, or is it worth proceeding?

Thanks to Roy's help and advice, I'm back on track with just another few small tasks added to my list.
Hopefully everything will work out with the head I'm waiting on. Once I get the banana rail replaced, the head back on (after hours more of cleaning), and removal and inspection of the vacuum pump, I'll be replacing the timing chain. I noticed a shiny spot inside the timing chain area on the block. Apparently using the arrow on the cam is a very inaccurate way to measure timing chain stretch. Mine said 2˚ stretch yet there are rub marks on the block. After those items are finished, I'll be replacing the front seal. New parts to add to my list are: timing chain dowel pins spacer ring front seal new bolts for balancer pulley Tools needed: timing chain separator timing chain crimper possibly a puller when doing the front seal?

Chad, The front seal is cake compared to everything else you are doing. For me the most difficult part was fumbling with the four 10mm fan clutch to pump bolts.
Also, I pulled the seal with a hook bent on the end of a stiff wire... coat hanger iirc. |

After comparing it to my head, I can see that the valves look different and the prechambers are a bit smaller when I overlay them in photoshop. I believe this is a 1980 NA wagon head. I'll try to get updated info today on the head I've been working on getting.

Glow plug hole size might be an indicator of vintage as well. I am not certain but do those glow plug holes look like the earlier series plugs? If so it has toi be a N/a head. Maybe my perception of hole size is wrong though.

I'm still waiting to hear back from the seller about the 1985 turbo wagon head test results. It's been a week since I last heard from him, so I'm thinking maybe I should move on.
remotemark found a turbo wagon head in MD, so shipping would probably be cheaper too. I just don't want to screw over someone who said they'd help me. Anyway ... I removed the radiator, condenser and fan today to make access easier for all the jobs that have been adding up. I REALLY need a head now. I have to put it back on so I can get my chain back on. Then I can rotate the motor and get access to remove the rail pin for the timing chain tensioner rail and replace it, roll in a new chain, and do the front seal.

The deal with the head fell through. I'm waiting to hear back about another head from a friend before I pursue the head remotemark found.
I'm just continuing to get things cleaned up while I try to get a replacement head here.

I'm driving to MD this Sunday to pick up a complete head that came off a running, lower mileage 1985 turbo wagon.
It comes with everything above the head gasket including the valve cover and it's guaranteed.

I found what appears to be another leak. I think the pic is showing the rack position sensor. The cable coming out of it is covered in oil right where it attaches.
I can't find any info about this other than it controls the EGR which is removed on my wagon. How do I fix this leak? Is there an o-ring in there or do I need a whole new cable? If it really only controls the EGR, is there a way I can cap it off?
