Hello-
I am visiting my mom until tomorrow and trying to do some maintenance on the 1966 AH 3000 BJ8 which we share (but lives at her house). The engine started making a worrisome tick, so I decided to tackle a valve adjustment for the first time on the off-chance that is the problem. The car is new to our family, so we don't know when it last had a valve adjustment. I had two questions:
1) Without access to the correct parts (a rubber bushing and cup washer), can anyone recommend a way to get a good seal at the valve cover fasteners. Whoever did it last had a steel washer against the valve cover, a copper seal-ring next, and then the nut/bolt fastener on top. To get a good seal, they used a ton of silver sealant (RTV like stuff). I don't have time to wait for parts and cannot find the correct parts locally. I will fix whatever I do with the correct parts whenever I am down here next, but I just want to get the car running again for her today. And hopefully without a ton of sealant.
2) The inside of the valve cover was rusting to the point that it was flaking off onto the valve train. I used a wire brush to get rid of any loose rust, but don't know how I can prevent this from happening. I would rather not use a paint in case it fails without me knowing it. I thought about a rust converter like phosphoric acid, but I didn't want to get acid on the painted side of the cover. Also, I don't know how that stable the resulting material would be at high temperature, so I didn't want to risk the experiment. I drove the car yesterday a lot and was surprised that there wasn't more oil on the inside of the cover to keep the rust away. Does this indicate that perhaps some of the oil spraying system isn't working correctly. Again, I am new to the car, so sorry if these questions seem silly.
Thanks for any help you can provide.
