Hi all
I seem to have vapor coming out from my dip stick when the dip stick is removed and engine is running? Ive done a search on this but all i can find is relevant to smoke from the tube which i don't believe this is, but as i caution i have stripped out the flame catch and that is unclogged and clean i have removed one end of the breather pipe and blown down it, with the dip stick removed i can blow oil from the sump up the tube and with the stick in place i can blow to a point then the air will blow back at me all of which i feel is correct for a unblocked breather system? But like i say i think this is water vapour (think) the head gasket was replaced on this car by a Volvo main dealer about 3 months ago at 137k as the top hose blew causing the engine to over heat , now i don't know if this has any bearing on this ? all is OK with the car now , i have done over 500 miles in it since we`ve had it and all's as it should be IE water is clean oil looks fresh temp goes up as it should and holds rock solid at half way, turn heaters to cold they blow cold turn heater to hot they blow hot , no smoke from tail pipe , although that said when you very first start her up you can see water vapour being expelled from the exhaust for a very short time? and no oil usage that i have noticed since we have had her and it runs like a Swiss watch Anyone with any ideas, ?

You do get a bit of condensation in the dipstick tube which sometimes leads to the milky gunk on the dipstick if the car isn't used often or for short trips). It is probably just burning off a bit of condensation from the tube. To answer your other question - they normally chuck out a bit of water vapour from the exhaust on startup (again its condensation in the system) nothing to worry about unless it carries on for longer than about 10 minutes which would indicate either head gasket gone, coolant seal in turbo failed or its just a really cold day lol.

No it only throws out from the exhaust for a matter of about 1/2 mins at a guess, not long at all

Could it be worn piston rings letting some combustion gases into the crank case?
Cheers, Pete

I think all engines have a certain ammount of blow by thats why theres a breather system, mine does the same, more so when cold, unless its severe i wouldnt worry mate, like you say theres no lost water or oil mixing is there?
How come your selling it so soon?, iam sorry if i have missed a post why, aint been about for a while

And more importantly is the car ok to use? as like i say it does not seem to be affecting the drive/performance it runs/starts/ and does not miss a beat at all and no oil /water seems to be getting use, ok i know its only been 500 or so miles, but all seems to be ok.

![]() But i don't want to sell a car on to some poor sod that has got a serious fault either , this is why im asking all these question`s , my mechanic mate has had a quick look and just said " i wouldnt worry about mate a lot of motors with that mileage do it, probably go on for another 100k like that" ? but it is not my intention to stuff anyone up. Should also add he recons because im so bloody fussy im looking for problems that aren`t really there ( he`s known me for many years) but i don't know if he`s right or not? my 854 doesn`t do it and that got 50k more on the clock so why is this one doing it?

Ive just done a quick test
What i have done is started the engine removed the dip stick and placed a clear plastic cup over the dip stick tube so as to catch any water/oil droplets that should form in the cup, just so as i can see whether it is water vapour or oil , but nothing loads of vapor or what ever it is? but as soon as it hits the air it just disperses leaving nothing behind? left the plastic cup over the tube for a good ten minutes but it stayed clean, not condensation build up no oil residue nothing?
