Feed back please. THANKS | | | | | Joined: Dec 2003 Posts: 2,733 Shop Shark | | Shop Shark Joined: Dec 2003 Posts: 2,733 | It should work just fine. Your old cover likely has a newer cap on it instead of the twist on style that looks similar to a radiator cap and has no vents. Don't know offhand just what the 58's used but am pointing out the different types that have been used over the years so they get mixed up. I think the solid non vented ones were used on the draft tube engines with the slotted covers but I may be wrong. | | | | | Joined: Sep 2012 Posts: 112 Wrench Fetcher | | Wrench Fetcher Joined: Sep 2012 Posts: 112 | Thank ,I did not want to drill any thing.This is not a part i would have picked up for myself.Going out right now to put it on .

There was no vented oil filler cap in 1954. As Dave posted, the valve cover was vented in 1954 (what about 1955-1st, Dave?).

Yes the 55 1st trucks I have seen used the 54 valve cover.
