I have read many times that bubbles in your coolant filler neck upon start up is a sign of blown o-rings. I have that problem but I am also getting condensation in the oil Filler neck and the oil filler cap. Is that also common with o-ring failure or should I be looking elsewhere.



Thanks for your help

 

I don't recall the bubbles at startup but for sure after the engine is warm. I also had title waves or volcano puking surges of coolant out of the filler neck. Oh and white sweet smoke at cold startup. I don't remember any condensation on oil cap.



Did you remove all air and have a pressure test (check for busted hose and radiator water tank) done yet?

 

The champagne bubbles is one of the signs. The condensation is nothing to get excited over though. If you really want to know for sure pressure test the coolant system.

 

I'll pressure test the coolant sys this weekend.



Is the condensation a somewhat common thing?

 

AFAIK the condensation-thing occurs when the car is used for short distances.

the bubbles....what type of bubbles? a constant stream? a few bubbles every few seconds is normal, since small air-pockets raise up due to the engine-vibration.



what else does you make worried? do you loose coolant, does the buzzer come off or does water get spilled on the ground?

 

There are other "hints" such as pissing coolant, and the level sensor going off. Again I stress the only sure fire way to know with 100% certainty is to pressure test the system. Then there is no guessing.

 

The things that have me worried



- I have some white smoke and condensation in the exhaust.



- Coolant bubbles(boiling appearance) and increses in volume upon start. I haven't let it get low enough to set off my coolant alarm. I don't even know if it works and I really don't intend to, unless it happens on a trip.



But anyway I'll give it a pressure check tonight and see if it holds until tomorrow.
