Slight oil accumulation in air bridge and air horn

[Don in VT]

Hi All,

Wow, never to old to learn something new. My thinking was that
the filtered air in the air horn is drawn into the cam cover and on through the motor and finally exiting at the PCV valves and on into the motor. I can now visualize that, under certain circumstances, the air flow over the inlet air horn hose fittings may have a venture effect and actually draw the air oil mix that is present in the cam covers. It is also possible that under certain engine conditions the vacuum drops off and the cam covers could go slightly positive with respect to the Air Horn and oil will migrate to the AH.

Anyway !!

I am not going to pull the cam covers at this time but instead come up with another solution to solve the over oiling of the Air Horn.

BTW, the ZR is all buttoned up now and passed its first smoke test and it is running great. I had O problems when filling the cooling system. The Samco hoses look great. The new thermostat controls well, The water pump is smooth and quiet. THE SECONDARIES ARE WORKING !!


Thanks to you all for all the help and support,

Don

Two things I know will contribute to the amount of oil accumulation.
1. thicker than 10w30 oil.
2. overfilled oil.

Hi Scottfab,

Thanks for the heads up on the oil viscosity and level. The oil level is spot on in the center of the hash marks and the oil is Mobile 1 10w/30.

Again, I appreciate the heads up

Just an update to the oil accumulation issue. It went away on its own. Perhaps it could have been that everything just needed to "settle in". Anyway it is gone.

Thanks everyone for all the help and suggestions.

Cheers,
