why does my car leak oil when not running?
when you start car, oil pressure increases and seals any leak
many people will know this from their own experience. if your car is not running, the oil is thin and pools at the bottom of engine because it can't coat all over engine due to no pump running. as soon as you drive the car, there's a sudden increase in what we call “pressure” which forces oil up to seal any leaks. this rise in pressure pushes out air pockets that cause “blow-by”. you might notice that after your motor was running awhile and then you turn it off and walk away for a moment, there s s white smoke coming out from under your hood…that was blow-by vaporized by increased pressure created by driving
will a car leak oil if it sits too long?
no, but it can make oil significantly more expensive.
as long as the engine is at normal operating temperature (or cooled down) and it's not under any pressure or load whatsoever, an engine will never leak until you go to drive the car again at which point there might be some dripping out of over-pressurized hoses that might not yet have had a chance to release their residual pressure.
you're much more likely to see wayward drips than to lower oil levels by just sitting around because fuel burns continuously in the carburetor or aftertreatment system, so short cycle time doesn't do anything meaningful. the only thing that runs continuously with the ignition off is electric devices like lights for your dash and headl
how much does it cost to repair an oil leak?
the price to repair an oil leak will vary per source, but can range from $50 to $800.
the total cost is impacted by the following factors:
one of the most important factors in determining what you’ll pay is where exactly your leak is occurring. it may be difficult for anyone to give you a specific estimate without inspecting the engine first-hand, but generally speaking leaks at any point along your engine are more costly than those that occur above or below it. this also applies if the leak occurs on either side of your vehicle near motor mounts or other delicate parts that might need replacement or removal for proper repairs. oil leaks caused by head gaskets can span all of these possibilities, meaning there could
