Without seeing it in person I can't really find an oil leak, just too many things that can leak, but it is likely just the filter...

It's most likely going to be an oil filter that wasn't tightened enough. The only other possibly for leaking oil on the back side of the engine would be a oil pan gasket.

I'm assuming you mean the exhaust manifold? If that's the case, I agree with Adam and Steven; check the oil filter. The valve cover gasket is a possibility but a very SLIM POSSIBILITY.

i took the car too a mechanic and a guy who dosnt speak english pointed out a black box next to the oil filter about 4 inches long 3 inches wide that he says is the prob but he dosent even know what its called ??

1. Oil filter or head gasket possibly??? I'd have to agree on what the other users are saying here. Chances are its as simple as that. I had the same problem in my integ (altho it was a 94 dc2 but the issue sounds the same). 2. If the mechanic your going to doesn't even know parts in your engine then just STAY THE HELL AWAY!!!!! No use having someone who possibly doesn't know what he's doing going into the engine bay and screwing things up. Also, you can replace the oil filter yourself to save some cash ( you need a replacement, canadian tire or some general auto shop will have them in stock, a special tool/wrench thing for actually pulling them off, lots of paper towels for clean up and your good basically). Also, if you can get yourself a copy of Haynes automotive manual for your year/make/model it will make the job alot easier as well. Hope this helps man!

Head gasket???...He didn't say the oil was contaminated, the car overheating or losing compression. Head gasket failure generally results in coolant leaks.

hey i have the same problem going on with my car and they said the same thing to me its that black boxs but they donno what it is do you know what its or if it is just the oilfilter ? did you fix the problem

Check oil pressure switch sending unit, very common leak. Threaded into the block just above oil filter. This is commonly mistaken for an oil fiter leak.

The black box is part of the vehicle pcv system. This could contain a small amt of oil but if it was leaking it would run out quickly and it takes awhile for any oil at all to build back up in box so therefore would not create any type of large oil leak

have aquestion just bought car with a b18A1 and im leaking oil from my block not quite sure yet but you can clearly see it has fuel in it and it wont even start at all sounds like if ther was a bad starter just does a loud clicking noise???

Bad clatter that sounds like the starter can be the valve stems frozen from old gas. The belt slips over the cam sprockets and sounds like a starter. I fixed one of these b18A1 engines recently, and the problem happens as these engines have tight valve stem clearances of around .001". Completely drain the tank, as a TRACE of this old gas will repeat the problem. You may have a drain plug. First, the stuck intake valves can be freed by slooowly prying each one open at the valve stem tip (takes a while as it's stuck) and then spraying starting fluid in the cylinder spark plug hole. After repeating this cycle about 5-7 times for each valve, it should be free, as the atomized spray will get above the valve face and onto the stem, as the valve has been opened. It will get easier to pry the valve down each time, until it is obviously freed from varnish and closes quickly. This SAVES FROM REMOVING THE HEAD, and works! Since the engine never actually ran like this, no valves were bent due to the original problem. Next, the timing belt will need to be replaced and timed. If there is ANY trace of the old, varnished gas left in the tank, then this will prevent the problem from happening again, until after several new tank empty and fill cycles: Before shutting the engine off, spray starting fluid into the intake hose, until it noticeably bogs the engine but does not stall it. This will clean the varnish off of the valve stems. Then shut off the engine as soon as you can get back into the car. This engine now has about 20k since this repair and runs fine.
