April 24, 2009noticed my oil pan is leaking wondering if im gonna have to lift the engine in order to get it off and replace the gasket *or* what. thanks
April 25, 2009It''s possible, but DAMNED difficult to do it with the engine installed.
Goes something like this:
Take off all 30 (*or* so) bolts holding the pan on. Some of them are a bear because of the crossmember. Break the pan loose.
Rest pan on crossmember. It will only go down an inch *or* so.
You have to break off the old gasket, clean the surface, etc, while never getting to see the surface easily.
There''s a tiny chance you will be able to fish the new gasket around the long oil tube that hangs down into the pan (hangs into the front of then pan, then a tube runs to the BACK, where there''s a wider pickup with a screen on the bottom, kind of like a garden sprayer for a hose). I''d actually advise you NOT to do that - it is probably going to be easier to just CUT the gasket in one place, and get it sealed together with some silicon sealer.
Then, put all the bolts together, and do some cleaning under there with degreaser because you probably got oil over a LOT of stuff that was previously dry (exhaust parts, etc.).
There are 4 bolts that are slightly larger - they go one on each side of the crank at the front and rear to hold the ''saddles'' of the pan up against the front cover and the block.
All of the bolts are only tightened to about 15 ft-lbs (that''s barely past finger tight). It''s the number, not the tightness, that makes the seal. If you overtighten then you''ll just bend the pan *or* squish the gasket out and have a leak.
The one piece rubber seals from Ford are great - DO NOT get the old school 4 piece cork and rubber setup unless you absolutely have no other choice.
I have done this ONCE, on a Classic Mustang, where I had a little more room. I would not recommend doing this job - let a shop do it.
Now, with that out of the way - it is likely that your car had the one piece rubber seal originally. It is also likely that the ''barely past finger tight'' bolts have just loosened up to the point of having a leak. Why not get under there and just snug all the bolts up? The rule is - if it feels tight to you when you are tightening it, it''s probably already TOO TIGHT. Just snug is fine.
