looking for help diagnosing an oil leak on my 93 accord lx 4 cylinder automatic.
the leak is slow but steady, if i don't add oil i suppose it might be down to
one quart within a month of daily driving, maybe 6 weeks.
i've found that oil seems to be everywhere starting high up with oil leaking down
and covering the backside of the engine and dripping down to eventually cover
the bottom of the pan with oil. oil will also leak onto the exhaust while i am at
a stop causing a burning smell at times.
i recently replaced the valve cover gasket to fix oil leaking into the plug sockets
and this is not the source of my leak, as there is no oil around the cover.
there is oil under the distributor and that may be one problem, but i still don't
think that explains the amount of oil on the backside of the engine? i have seen
posts mentioning the oil pressure switch, anyway to check this with the engine running?
basically i don't want to go replacing seals without identifying the leak.
other than the leak the engine runs fine.

Pull back the rubber boot to the oil pressure switch. If it has a bunch oil in it, replace it. It is an inexpensive part that you can get from the dealership. Also repair the distributor oil leak by replacing the o-ring.
Tracing an oil leak can be a pain. Repair the leaks that you have found. Try to clean the block as best as you can. Drive the car a couple of days, then look for oil. Oil will only leak down, so try to find the highest point on the block to get an idea of the source. You can always have some dye added to the oil and have a mechanic look at it. It can't be too expensive to diagnose.
replaced both the distributor o-ring and the oil pressure switch, now i'll
just keep a close eye on the oil level the next few days to see if that
helped the problem. thanks to those who helped me out.
for anyone interested, the cost of parts from my local honda dealer:
oil pressure switch=$13.55
