I might have if we didn't have a Honda Cup event tht weekend.

Funny they told me these valves rarely fail .

 

Mine didn't completely fail ... but it did spring a big ass leak. Let me know if you ever decide to make the trip up.

 

Richard, I guess you are one of those rare case


is anyone here also using the one way check valve? I've run both with the check valve and without it - with the valve it drops maximum oil pressure 5 to 10 psi above 6k rpm.

I hear that if you plumb the accusump after the oil filter you can use the built in anti drain back feature of the filter. I T'd in the accusump before the filter and do not have this feature. plus oil that gets in the sump is unfiltered.

 

I replaced the $15 brass Canton check valve with the aluminum Earl's (for AN fittings) which is larger/better design that should be less restrictive, but costs like over $100.

 

you know where I can get one?

 

I recall I bought mine here: http://www.anplumbing.com/shop/index.php?

But it should be available a any race shop, just Google.

 

I found it. thanks!

 

Yea the Canton check valve is a wuss 1/2" NPT.
You want a true AN-12 for no restriction on flow...same goes for a thermostat.

 

even Earl's -8 looks less restrictive than Cantons!
