I've seen plenty of ecotecs with old intake gaskets but this one was more milky than you normally would see on the radiator cap and in the expansion tank.

nah, all of mine been like that even with less than 100k on the clock. They perish from age not from mileage.

Re: Low oil pressure warning when braking hard ?
Yeah, I know that, seen plenty, it's just that this one seemed worse than I had ever seen and very suspect that the oil and coolant was changed before been put for sale. Coupled with the low pressure oil warning I'll think I'll leave it be.

Re: Low oil pressure warning when braking hard ?
yeah the VT l67 seem to have a rep for failing with bearing, low pressure etc...
I personally wouldn't want an ecotec lower than VY or VX series. That is when they became bullet proof engines. VS and VT suck for the majority of them.

Re: Low oil pressure warning when braking hard ?
oily sludge on the radiator cap and in the overflow tank can also come from the auto, i see it quite often when the factory radiator gets to around 5-10 years old, if your lucky the auto fluid only gets into the radiator but i have also seen it when it goes the other way and the auto gets the coolant and then your up for a new auto

Re: Low oil pressure warning when braking hard ?
This problem with the valley gasket amazes me. How does oil under no pressure get into a cooling system that's usually under pressure except for maybe during cool down where air is drawn in via the atmospheric valve. I know it happens and have seen it fixed by replacing the gaskets but how?

Re: Low oil pressure warning when braking hard ?
i guess if there is enough blow by in the motor it could cause some pressure ?
but then plenty of engines over my years have done things i still can't explain

No matter what the question is, the answer is always more horsepower!

Re: Low oil pressure warning when braking hard ?
it happens during cool down and the vacume in the cooling system sucks a small amount of oil that has gathered on the gasket into the cooling system and over time this oil is what is seen on the radiator cap, the gaskets I have done are collapsed into the cooling passage and I would assume the when the cooling system is under pressure it forces the collapsed area of the gasket to close up and seal hence why most of the time you don't get coolant in the oil

Re: Low oil pressure warning when braking hard ?
OK that's the only thing I could think of was during cool down. I didn't know about the gasket design. Almost every V6 Commodore I have services has that very problem and I was told it was fixed by changing the gaskets.
