hey guys...my friend has a 93 lude with an h22....he has an oil leak but we cant figure out where its comming from....i checked the oil pan no holes newhere...it kinda looks like its commin from the back of the block ...could it be that the oil sensor cracked or something like that? if anyone knows what it can be help is appreciated

 

if it's only when the car is on it may be the oil cooler o-ring.

do a search in the prelude archives. it's between the cooler and the block. the cooler is what the filter screws onto. the o-ring costs maybe 3$

 

no it leaks when the car is on i think there is a hose that goes from the cooler to the black can that be it?

 

that hose carries coolant...the leak is from the o-ring under the cooler. take off the oil filter and the big nut on the stud it screws onto. very common prelude problem

 

if it drips on th pipe and smells really bad. It's the oil cooler.

 

common problem on older honda engines... easy to fix though...

 

today i saw that it doesnt come from the back of the block but comes from under the timing belt cover..i think it might be the oil seals by the crank what do u guys think....on preludes its really hard to see nething bc the motor is so close to the fenders i can barely fit a finger in there
