Blow-by retention cap (Oil cap) “OIL”

Description

If you’ve ever taken your oil cap off while the engine is running and watched it chooch out a sick vape cloud, you know why it’s called a Blow-By Retention Cap. Under that cap… what’s in there anyway? We know there’s oil in that engine, but what else? Dirt? Bearing material? Ethanol? Water? AOS Sludge? Ring lands? We may never know all of it, but we do know it’s Mostly oil.  We also know you’re probably running Rotella T6 diesel oil in there and totally ignore what Subaru says to run.
So there you have it, a Blow-By Retention Cap that says Mostly Oil and Ignore Owners Manual.

Maybe you’re the more optimistic type. Well, we also have a cap that’s just as optimistic and says “OIL”.  This is the listing for the OIL only cap. Just choose your color and knurling option.
Cap is clocked to the correct position to be sure your OIL cap doesn’t say 710.
Will come with new OEM O-ring.

Don’t forget to order a matching battery tie down.
Limited numbers of each, so you may choose a combination that isn’t available. Please put in the order comments any aspects that are flexible, just in case. Alternatively, you can send an email to ask if the one you want is in stock.

Thanks!!!
