Re:Older 5187 Valve Covers:Did they come w/Breather Riser Tubes vs new version twist groove & no riser tubes?

OFFYEXPERT Posted new comment February 8, 2022

Older castings of the 5187 valve covers had the twist on breather. The pattern was changed in later years to the breather tube style. The breather tube style is the only one available. The diameters available for the tube are 1 3/8in. and 1 1/2in. Ace Automotive might have them in stock. Their phone number is (435) 477-8213. Otherwise you will have to place an order through one of our distributors.
If you are looking for the twist on breather style then you’d have to look for an older casting, because we no longer manufacture them. Hope this helps!
