I have a OE JDM B18C Type R bottom end, a ported and milled 0.020" head with Toda Spec b Cams and after 5 laps of revving to 8600rpm, my cams seals behind the cam gears always leak...to much crank case pressure????

I have an Endyn breather system:
- Removed and blocked the OE little black canister behind the block so removed the OE PCV system
- Removed the passenger side Frosh plug and installed the Endyn Feed outlet which goes to the catch can.
- The return under the catch can is sent back to a T-Fitting in the above blocks feed line (like indacated in the diagram that you get with the Endyn system)
- The valve cover OE Cam breather outlet is sent to the catch can

Motor compression when cold is 235-240 across the cylinders????

 

Wrong section. Wish I had an answer though, I've never seen anyone have this problem before.

 

are they new seals?

 

stupid question, but can we assume youre putting a bead of honda bond on them?

 

Yep, new Honda Seals...I'm trying to find teflon ones?

I'm putting a little bit of Grey Sealler arround them?

I'm assuming it's to much crank case pressure???

 

I had the very same problem a few years ago in my B20 Motor. Funnily enough I had an Endyne Breather System as well...
I ended up running two -10 breather lines from the Valve cover.
FWIW.
