Title: steam coming out - oil cap
Post by: mjv on 22 May 2008, 08:17

hi

i have just recently joined the forum....great to be here !

i have been checking the engine oil levels after using my car & i can see some steam coming out of it when i open the oil cap.

also i have been regularly checking the oil levels and the oil at the dipstick is clean i mean its not dark or with any cr*p like that etc...

now is this steam coming out is normal or is this a problem with the engine???

thanks in advance for your replies.....

cheers... :smiley:

Steam would indicate water in your oil, which you don't want. You sure it's not just oil vapour?

hi

thanks for the reply...

i think its the oil vapour, also i have been checking the oil level (obviously on a flat surface with engine being cooled say 3hrs) and the level its right on top of the chequered area of the dip stick. so its not burning oil i guess.

do you think when the engine is warm the oil will have vapour just like in the kitchen when frying stuff you can see the oil surface does have steam !

pretty sure i dont have water in oil coz i just changed the oil n filter 2 weeks ago

I'd say it was oil vapour, you don't say if you have checked the oil when the car is cold? If there was a leak you would possibly have oil residue in the water expantion tank.
