Why would you picture damaged seals? It does not matter how much you overfill the system... the oil pressure will not go up. Think of a gas pump at the gas station. There could be 300 gallons of gas in the underground tank or 3000 gallons of gas in that tank. It makes no difference in the amount of gas coming out of the nozzle at your pump until the level gets low enough that the pump starts sucking air. With a 3 quart overfill you should picture bearings destroyed by a lack of lubrication. With that much overfill the crank will whip the oil in to a froth and the oil pump can't pump froth effectively so your oil pressure goes down until you stop or the engine stops. The seals aren't subjected to any serious pressure. They mostly just keep the splashing oil from leaking out. Worst case scenario is a seal would be sitting in oil and might leak a little until the oil level drops back under it. Steve B. |
enough some seal or gasket will let loose from dynamic localized
pressure (I just snuck the word gasket in there).

it up there would be some increase of pressure. I have never actually
tried filling an engine until it was full, but I would be extremely
surprised if all the oil stayed contained inside the engine when it was
started up.

that the service rep explained that Hydraulic Lock was the cause of the
engine failure. This sounds believable (why would they lie). What he
probably got confused about is what valve was involved. It probably
wasn't the engine valves but the PCV valve that caused the failure. I
can imagine, under the circumstances described, a geyser of oil being
sucked into the engine thru the PCV valve.

BTW, I was the original poster. and after a few days, I took it to WALMART and got the oil changed for 18$. As I did not have the time/energy to try to drain out accurately I quart. My van works fine, I hope so. I think I drove only 20-30 miles with the extra quart... I hope I did not cause any damage. Are you sure you had an extra quart in the crankcase? I typically see |
exact amount specified in the manual and it always looks overfilled.
I've noticed the same thing on several cars I've owned and never had a
problem.

.....who was posting that one could experience a hydraulic lock due to
pressurized oil getting past his valve seals and locking up the piston -
which is what I questioned.
The poster discussing the 3 quart overfill never uttered a word about
blowing out seals.
He just claimed that Jiffy Lube replaced the engine after I questioned him
about hydraulic lock caused by pressurized oil bypassing the valve seals
into the cylinder.
Yet another poster posed the theory of a large overfill generating enough
pressure to blow seals - not necessarily blow the engine - but I would
think the standard crankcase ventilation system would absorb any pressure
developed.

Does it still check over-full after running it long enough to fill
the filter?
Take care.

for a few minutes at idle just to make sure there are no leaks. Then I
check the old level and it usually reads high by at least a half quart,
maybe more. I don't even wait for oil to drain back into the crankcase,
I just check the level to make sure it's okay and I didn't do something
stupid. I like to see the nice clean oil on the dip stick. :-)

find was your advice to the OP and who seems to have resolved his
problem.
Things do get lost though. I offered a wild theory to sort of support
the idea of a hydrostatic lock in the bottom end of the Honda engine
that may have blown some end seals but it didn't appear in this group
thread. Instead it ended up as a cross post into the group that the OP
included in his original post.
