1516.0. "Gungy Caps!" by CRISPY::GERRYT () Thu Jul 25 1991 14:20

    Recently had new head-gasket & core-plugs put into cylinders on my VW.
    Now finding a lot of rust coloured "gunge" deposited/floating around
    the filler cap area of the radiator.
    
    Could it be the strength of the Anti-freeze causing the deposits to
    come loose ?
    Any danger signs in this sort of display?
                                            
    thanks,
    
    Tim

1516.1	Oh dear, looks like someone hasn't done a good job !!!	CRATE::RAWSON	Fnarr! Fnarr!	`Thu Jul 25 1991 14:25`	4
	I always belived that was a good way of finding out that your head gasket had gone ! Alex
1516.2	Why?	DUCK::GERRYT		`Fri Jul 26 1991 14:10`	3
	ref -1 ....Alex. Why, what's happening inside? Tim
1516.3	Yup, gasket gone !	CRATE::RAWSON	Fnarr! Fnarr!	`Fri Jul 26 1991 15:27`	5
	I think that the oil and the hot water do some horrible things to each other, resulting in this froth. Is the froth a sort of discoloured beer head ? Alex

	If your garage only changed the head gasket they may not of drained down the cooling system compleatly.First before having the head off again I would drain down the cooling system and flush it through. Refill the system again and see what appears, if you get the white sticky froth aroung the cap then you most certainly have oil contaminating the cooling system water. I've had bits of muck in the expansion tank on my Metro for years (must clean it out one day)with no problems. phil
1516.5	Rusty Froth	CRISPY::GERRYT		`Tue Aug 27 1991 13:26`	10
	Sorry, haven't been into the Notes files for a time. Yes, the 'head' on the water is a rust-coloured froth. Haven't checked it out recently again though. There are no overheating problems noe...but will check water consumption. Thanks. Tim
1516.6	Anyone for rusty Big-ends ?	SUBURB::JASPERT		`Tue Sep 17 1991 14:03`	4
	What is potentially more serious is water entering the sump & contaminating the engine, I hope you had the oil & filter changed at the same time! If not, suggest engine is flushed with Flushing Oil.
