Hi, have recently replaced stock cams with the S&S cam drive kit, original cam backplate & pump, S&S adjustable pushrod. It runs excellent but every now and then it blows oil out of the filter housing, especially if we go highway riding. Where have I gone wrong? And what would be the fix? In advance thanks!

Those could be your problem.
How many miles on the engine ?
Did the lifters get replaced ?

 

[Ole H]

Forgive my late reply, oil pressure is about 35 at Idle, 45 - 50 at 3000 rpm

 

[Ole H]

Yes, replaced lifters with the new ones from the S&S 510G Gear Drive Cams kit

So ... how many miles on your engine ???

 

[Ole H]

Has been changed speedometer a couple of times, but a qualified guess would be just about 100 000 miles

By those numbers I'm thinking the cam plate relief valve could be stuck.

Sounds like a stuck relief valve. Those oil pressures, at least idle are high.

 

[JLR]

The relief valve bleeds off pressure at the high end - shouldn't effect idle pressure. You might want to verify the pressure with a mechanical gauge.

What about running a half a quart low like other threads suggest? Never said what a/c you're using.

Run your oil qty 3!4 full on the stick

Too much oil can come out of the breathers in air filter housinh

Fixed my bike this way

This is the problem 80% of the time .. I run mine at 1/2 between the Add and full Mark and never had this happen but seen it happen lots for some that insist on running theirs right dead full at all times ..
