What are potential oil leaks on passenger side of the engine?

[jhelton001]

I have a oil leak on my 97 DI that I have been chasing for a while and I’m starting to run out of ideas. The leak is in the passenger side of the engine and so far I have replaced
Oil cooler hoses
Oil Pressure Switch
Valve Cover Gaskets
After replacing parts I cleaned engine and after a interstate trip I have oil on the passenger side of the engine. The front crank seal is dry as can be so it can be ruled out. What are potential oil leaks on passenger side of the engine?

Can you tell if the oil residue is concentrated more in the front, center or rear of the left side? There's probably so much air turbulence under the hood and that's why it hard to detect the origin of the leak. Especially if its a seep.

Oil cooler lines, front of the valve cover, oil filter...

all of these tend to weep and the oil migrates as the disco rolls down the road.

Pressure washer is your friend...then watch it every day for the first sign of new oil.

I just did this last night on my LWB. Directly above the oil filter, there's a dime sized plug held in with a snap ring. Clean that area well and remove the snap ring circlip and oil pressure relief plug. Remove old brittle oring and replace with a BS017 oring. Put back in, which is a big PITA since theres a spring behind the plug. Snap ring pliers come in handy here. Use one hand to push the plug in with a 3/8 extension while using the circlip pliers to sorta get that circlip back in. Make sure its seated properly. Done. No more drips!

Could also be the valley pan gasket, or head gasket. Pray it's not the latter.
