So i fitted a catch can a couple months back, probably cover 300miles since having it installed. Whenever i drain it, usually after each journey its got some water in it, condensation no doubt. But last time i checked i had done 100miles with some hard driving and it had an oily water mix of probably about 25ml in it, it was very watery i'd guess 75% water.

Anything to worry about?

 

Hi ive alway run oil tanks on cvh and cosworth etc my cars are used all year round and u do get water in them mainly when its cold weather sometimes there get like thick white yellow brown water but apart from that nothing wrong with cars or engines etc so i would say its just the weather u no etc

 

Wouldn't worry too much. Temp's have been all over the shop and it depends how those 100 miles have been done too - if theyve been 10x10mile drives, then condensation is just a given.

 

Thanks guys, i would say afew short journeys and the engine has sat for years before hand so maybe shes just sorting her life out internally.

 

Yer definitely nothing to worry about if its been sitting. Its ridiculous how much water vapour can appear - just sitting in breather hoses etc over time. Glad to hear she's still out there and being used!
