I have noticed this for awhile.Dont seem to be using any water or oil.Motor seems to be running fine,although heater seems to take awhile to heat up.Any clues?
How much is in there? cause if its like a yogurt lid then i would be concerned that its a head gasket. Unless some goober has put oil in ur cooling system.
If the previous owner followed the proper guidelines on coolant he would have added a number of "tablets" - supplied only by Holden with his last coolant change. These "tablets" are supposed to lubricate the water pump among other things and will leave a brown oily deposit on the radiator cap. Also a lot of mechanics will use grease or oil as a gasket/sealant when assembling engine components - this then finds it's way into the cooling system and as oil is lighter than water it floats to the highest point - the radiator cap. Good Luck.
I wouldn't worry too much - like I said before it's normal if the car has been serviced according to the factory guidelines. The heater on Commodores is fairly slow to warm as the heads are cast iron - takes at least 2km to start giving heat...you could change your thermostat which may be jammed open - also check the heater tap....make sure it fully opens when you turn the dial to hot.
Yeah, check your oil next change... if its really bad (milky) its gonna be either your intake manifold gasket or your heads.... id go IM first as they tend to go more often than the heads do... either way it has to come off should something be wrong! aZk.
is the 4.3 for an ecotec ey coz my dipstick is ***ed out so i just been putting 4.5 in but if ur sure its 4.3 than i shall only use 4.3 next time
lol... Well clearly you must have one of those super-rare-elf-made ecotecs! Only a limited amount of them came out with 5L Capacities!
Haha, that emoticon obviously wasn't worried-looking enough. My point is i have no idea why i can pour around 5L in (definitely more than 4.3L, anyway).
Mine takes 5.4 Litres, it's a vy ecotec, even the book states so. Surely the vs ecotecs and the vy ecotecs didn't change their sump capacity by 1.1 litre?
As others have said it sounds like oil, but with 12 months of hassle free driving i wouldnt be worried about it, if your that worried about it speak to your mechanic about a leak down test
