I have a bad oil leak on my engine. It's around the oil filter. It is
worst when the oil level is full, not when oil has leaked away.
My mechanic is "sick" of this car (I've had it 15 years) and did a cursory
look; he thought it would be a main seal. I have the silver shop manual and
I see some small oil tubes running around.
Has anyone had this problem and fixed it?
I replaced the PCV valve but that didn't help (there is only one PCV isn't
If you haven't changed the oil filter since the leak appeared (not sure how
recent that was) that is an obvious start. They operate under pressure and
the gasket can fail to seal perfectly. When the filter is off, wipe the
mating surface on the block and feel it with your fingers - it should be
smooth... no bumps or pits.
Once the new filter is in place, clean the oil away. My favorite for that is
Simple Green, because it doesn't leave an oily film like Gunk does. Just
spraying the area, then hosing it off should do the job. Take the car for a
short drive and look for the source of the leak - maybe it will be gone :-)
Don't know about your engine, but the oil pressure sender is right above the
filter on a lot of Hondas. They can be a challenge to get loose (that boot
really holds onto the sender) but otherwise easy to replace after you get
the filter out of the way. Many new ones require a special socket, though.
This has been going on for over a year. It's not my filter. I had the
mechanic take a look at it when he did my brakes this spring.
I'll check the oil pressure gauge area.
Thanks for the tip on Simple Green. I hate trying to remove oil. As it is,
I smell it burning as I drive. :(
There is a rubber o-ring behind the adapter for the oil filter. It is
between the block and the cooler. It is very prone to leak due to age. The
o-ring is shaped like a figure 8. The coolant hoses that are attached to the
cooler are usually very brittle and will need replaced when you take off the
cooler. Kind of a PIA!! Good luck
