Oil in the Air Box
05 Jul 2024 19:39 - 05 Jul 2024 20:03
Was finding oil puddling in the bottom of my air box...
It was coming out the rubber hose that connects the breather cover to the air box, and making a bloody mess...
Is that a common issue with the big fours?

Probably, but not more than usual...well, maybe a little.
But I don't feel guilty...she likes it you know.

Time for a compression test. Oil in the air box is caused by excessive positive crankcase pressure due to compression blowby then venting through the crankcase breather.
Z1000J2 somewhat modified!

Been using Rotella 15W40 T4...
Wasn't finding much oil, but residue buildup over the span of several 5-8k rpm rides.
This stopped that completely:
...and there are no oil leaks anywhere on the motor!
Dry as a bone!

7/06/24 compression check results:
cyl psi
1 & 4 160
2 & 3 145-150
Half a quart of oil evaporated on today's 100 +/- mile ride...
She loved every breathtaking moment through which we flew!!!

Re: Oil in the Air Box
07 Jul 2024 04:37Love that solution Dave, is that "ram air" filter foam or something similar that won't cause a pressure build up??Been using Rotella 15W40 T4...

Yes, and it performs much better than expected.
It's a strip cut from a sheet of RamAir filter media I acquired nearly ten years ago.
It may be similar to the material used in their product offerings today.
