Hi everyone,

When I have to remove the right valve cover on my '58 318, the downdraft tube is always a pain in the a**.

I see on the parts manual that it's supposed to be a 2-pieces thing, but mine seems to be 1-piece.
So removing it means either that I wiggle it out, with the lower screw still attached, but it can be destructive.
Or that I try to unscrew the lower screw, but it's almost impossible without having the car on a lift.

I thought of cutting the tube and using a rubber sleeve that I could disassemble at will.
What's your solution ?

Not really a solution to your dilemma, but you could just convert it to PCV. My engine had a PCV conversion done decades ago. The draft tube was removed and has the valve that then feeds at an intake port and the breather cap feeds the into the air cleaner. They brazed a tube on the stock cleaner for the hose fitting. Keeps the oil and chassis a little cleaner.

Also...the proper name for those is the valve covers.

They are difficult to remove. You have to remove the screw at the bottom first, or you don't have a hope. Once that is removed, some heat at the connection will help to remove it.

When I replaced my downdraft tube, I used jack stands for safety after jacking the car up and the retaining screw/bolt was easily removed.
