The tutorial I am using for the 78s is a bit different then mine in this area.



The tutorial has a plate with 2 bolts here not this big nut.




I cant get the big nut or the hose clamp off to remove this oil tube.


will the cover come off without taking this oil tube off?

There is no room to put a wrench on the nut without hitting the radiator. I can get a adjustable on it but it is just going to strip the bolt head it is so tight.

'78 oil tube pickup is this and you need to be patient to take it off. It took me 2 days with the appropriately large wrench and rust blaster of your choice to slowly work this out with a hammer providing short "stunts" to shock the nut loose.

Yes, in my experience, you need this off in order to take the cam covers off.

Drain oil first, the level is higher than the top of the pan.

Remove rad to get space you need.

Use penetrating fluid.

Also i think there is a bend in the pipe below. So u need to twist it out, not just straight up. Remove hose and clamp. Replace hose if hard or cracking

Thank you all for the help. I already had the oil drained, sprayed it with penetrating fluid will try to loosen it in the morning.

There's no bend in the early 78 (only) pipe (928 107 039 01, up to engine 828 0689, for 5-speeds 828 9080 for autos), so it needs to come out in order to get the timing belt cover off. 36mm service wrench for the hex at the bottom. Good idea to drain the oil first, if you don't, you'll lose about 1.5 quarts...

Take the radiator out. All the coolant hoses to it will be disconnected and the coolant will be drained for the project anyway. Left in place it's a damage magnet, grabbing the free ends of tools in your hands and drawing them in to reform the fins and tubes. Radiator out adds several precious inches of room for stuff like pulling the crank nose bolt. And the oil filler tube too I guess. Minutes to remove and replace, priceless having it out of the way. And... vacuum and wash all the leaves and crud that are hibernating between the AC condenser and the radiator. While You Are In There.

What penetrating fluid did you use?

+1 on removing the radiator. I think I would remove the hose off the top and put the box end of the wrench over the whole nut to break it loose.

DaveSehl

thanks for all the help. I sprayed it with penetrating fluid and it came off real easy today. got motor set to TDC waiting on my tool to lock it in place. I took a pic of the radiator and it wasn't bad with leaves etc for being 40 years old!


I do need a new air pump filter this one is starting to crack a little bit. Hopefully Those are available.
