Leak at filter cover

Decided to give the old girl an oil and filter change. First time using a two piece filter. So after starting the engine I noticed a few drops under the filter housing onto the floor. :? I replaced the white O ring,
steel washer and cover gasket. Just thought I'd ask here, what the most likely problem could be, before taking things apart.

Thanx! ZM

Have you measured the depth of your filter canister to make sure you even need the paper gasket?
One of my happiest days on the R65 was when I quit using that.

Well I've always used the paper gasket without a problem, the only thing new is segmented filter. The oil pressure light went out on start up.

Did you get the right filter? There's one for with oil cooler and one without. Also, is it possible the old steel washer was left inside?

Also, did you put the steel washer in before the white o-ring? I've seen that done backwards the result being the steel washer slipped down when installing the cover. It ran and had oil pressure, but ????

Hmmm, gasket not working, o ring not working, hmmmmmmm, did you put the cover plate back on? :ugeek:
And if you did, did you put the bolts back in?
There's only one other thing I can think of, but let's not jump too far ahead.

I think the metal gasket slipped down and got pinched so I put in a new metal gasket, now I've got a problem threading one of the screws in. Not having a happy day in the shop. :| Guess I better get her up on the lift and see if a thread got burred. Sometimes the simplest things give the most grief!

Get a tap and run it through. A primary or secondary tap, not a bottoming tap because it is too easy to run off thread right from the start.
A primary tap will be the easiest to pick up the true thread if I'm not mistaken.

Don't screw with the bolt, if it's not too late.

How's that, better post?
