Title: moisture in valve cover breather cap
Post by: fryedaddy on October 17, 2017, 02:51:07 PM
i have moisture in my cap and a little smoke or steam coming out of my passenger side valve cover breather cap.i dont know if this is an issue,i just had the intake off and i have not changed the oil yet.i thought a little water may have drained into the engine when i removed the intake manifold. i need some opinions.

Take a long drive, say 1 hour, highway or not. Park it, check it. Then, check the next day before fire-up (local humidity, day/night could affect it too as the engine cools, especially if the car is on grass, not concrete).

How hot is the engine with the t-stat open? Low temps will do that too...........

Yeah, you may need to get the highest rated t-stat you can for an FE. Not sure if a 195F is readily available but it should be.

Could be steam from an internal leak or could be condensate burning off.

If the oil on the dipstick is not gray take it for a long drive
an hour or so and se if the problem go away check  the color
on the oil now and then and check coolant level during the drive

[/quote  could it be steam where i changed intakes and let a little coolant escape when i lifted the intake off the engine
