well lads noticed and oil leak on the sil80 the day i got it only when engine is running so havin talked to a few people we thought it may have been the wrong oil filter fitted as the engine is a s14 engine....

so changed oil this evening and still leaking...It seems to be comin from a sensor or solenoid (not sure wat it is) that sits just above oil filter going into the block...

wat is this part and is it a big job sorry couldn get a pic as it was dark
