Good afternoon, all. I have run into a fitment issue and I am hoping for some assistance. I have installed Mummert's aluminum valley cover and Spotlite Kustom Accessories valve covers, but the oil filler tube is basically the same height as the valve cover, so I'm having trouble installing a breather cap. Can the oil filler tube be replaced for a longer one? Is there possibly a smaller breather cap that can be purchased? I can provide pictures of what I've got going on if need be. Any advice or information would be greatly appreciated.

Thanks,
David

Having installed the Mummert valley covers on the Y engines, I don’t recall any clearance issues with the oil breather caps.  Without looking at a Mummert valley cover on an engine, I’m going to say that you possibly just need a smaller diameter oil cap.

If you have to go to a small cap.. keep in mind that on a stock engine, that is the only air intake for the crankcase breather setup. The filter material needs to be checked & serviced regularly or it will plug up & the engines crankcase breather setup will not work..leading to slugg buildup etc.

Doesn't John recommend a certain cap for his valley covers?  I have one of his covers and thought I got my cap based on his recommendation.  Here it is

I've ordered the Spectre #4280. I will keep you posted if that works. 

Remember the old saying; "Chrome won't  get ya home"!

I've been using a cap like this one on my Vicky for years. I like the shield that prevents airflow from entering the tube. They are available from most of the regular makers. I think I bought mine off the wall at O'reillys.

The 4280 worked. No clearance issues.

Hey Moonshadow;  Obviously I'm missing something here.. Why would you want to prevent air going into the filtered oil cap ?  Does your engine have another source for crankcase ventilation?.. Or ?
