Another, more likely
way a head gasket leak could cause this high oil level would be a coolant leak to oil.
Not exact matches
As a result, when the
head gasket fails, oil can make its
way into the coolant system.
One
way that a
head gasket failure could cause overheating would be if the
gasket failed between a combustion chamber and the cooling system.
In no
way does the symptoms scream
head gasket to me.
IMO, it sounds like a
head gasket, but there is no
way of knowing unless the engine is taken apart.
leave cap off make sure fill with antifreeze and start car allow it to warm up and watch u should be able to see the water flow this will allow the air to come out per air pockets are a big cause... now buy a new radiator cap per this also small but cause a big prob... also while watching the water flow flow if bubbles stay present it could be
head gasket this pushes combustion gas thru and can cause antifreeze to dicipate hence why u keep having to put more unless yur pump leaking or hose this the only other
way u will get low on anti freeze... hope this helps it took me a while to figure out so i did nt have to spend lots of cash on a mech that wouldnt probably now this either top secrets lol... they wont tell u its all biz... hope this helps
If coolant is making its
way into the oil pan (bad
head gasket), the engine can seize since coolant doesn't lubricate very well.
I have been researching and came across information about how non oem parts could not work propertly and when dealing with hondas oem is the
way to go, so I am not sure if I should replace both with oem or look towards a blown
head gasket
Anyway, to sum up,
head gasket failure is more common but intake
gasket failure is the only other
way exhaust could smell like coolant, especially if oil and coolant aren't mixing.
The only two possible
ways that antifreeze will make its
way into those chambers on its own is a «blown»
head gasket or intake manifold
gasket.
My money is on the
head gasket, because that can fail in a fairly on / off kind of
way, but as other...
In the case of the original question, the actual problem was that the plugged cat had caused the problem of the blown
head gasket, not the other
way around.
