Condisation comming from valve covers

[Larrys78]

Crusaders XL FI. The pcv vent tubes seem to be expelling alot of moisture into the throttle body or carb. Anybody know what is causing this.

Be helpful if you give us a bit more to go on....

If the engine is cold and the ambient humidity is high (or recently was), this is quite likely normal.

If the local air is "dry" and the engine has just finished a three hour cruise, I'd say it is abnormal...

 

[Larrys78]

Humidity is normal temp outside is 49% half hour cruse at 3000 rpm. The key factor is the Portside engine is dry absolutely no moister what so ever.

Check your t-stat.

Been there done that

Your engine has a 140 degree t-stat. I would bump it up to 160. If you still see condensate, I would pressure test the engine block.

Are these raw water cooled (no heat exchanger)?

Fresh water
