Default Major oil leak

So ive been trying to pinpoint this leak ive been having, while letting the car warmup for a compression test today i got to poking around, and figured out the area its coming from.. Its dripping down the pan from the front of the engine.

So that leads me to think its one or more of three things, valve cover gasket, cam seals, or crankshaft seal.

The oil leak is major, like leaks a lot, could the valve cover gasket or cam seal leak that much? I figured if they leaked it wouldnt be TOO major, so im thinking it might be the crankshaft seal

I'm going to replace the valve cover gasket and cam seals because they are easy, and i guess ill see what happens, but is it pretty likely that its my crankshaft seal?

You got it there bud or, if you are very unlucky it is the seal on your oil pump.

no to the valve cover,

cams seals are easy enough to spot, just pull the cam cover. or simply check for oil above the crank pulley.


if it's the FMS it's not a horrible job, just a pita. I did it once when it turned out to be a cam seal the popped out when i put my cams in. whoops.

Get some uv dye for oil and put it in. Turn it on and break out the uv light.
