Default 87 FJ60 oil leak?

Looking for pointers on where to start.

Recently returned after an1800 mile trip with the 60 and found that it was blowing engine oil (2F) out from somewhere around the fuel pump, oil cooler or oil filter. I did an oil change just prior to leaving on the trip.

Additional info: I replaced all the seals on the engine, including rear main with OEM seals about 5 years ago (except head gasket). Including the oil galley plug fix.
The engine has never leaked oil before. I lost maybe half a quart, but it created a hell of a mess under the truck so I can't really tell where it's coming from and was hoping someone else has experienced this situation.

Much appreciated!

There is a plastic spacer between the fuel pump and the block. Check to see if a chunk of the spacer is missing or is the fuel pump bolts are loose.

Check the oil filter - it doesn't have two gaskets between it and the mount?

Much appreciated!

What about: PCV? Side cover gasket? Valve Cover gasket? Oil Cooler rings?

I'll check the PCV and oil cooler rings.

Side cover, valve cover are relatively new.

Thanks!

Thanks for all the suggestions. I spent a couple of hours this morning looking over everything, replaced the oil filter, tighten the fuel pump bolts and checked the oil cooler bolts but I'm still not 100% sure of where the oil leak came from.

Was curious if the oil pressure sending unit may have caused it or if there is an oring on the distributor that may have failed, but I'll clean everything up and see if I track it down.

Thanks again.

Found it!

After cleaning the engine bay I took the 60 for a run and when I got back there was more oil around the oil cooler, distributor, etc .... so I tried to figure out where it came from and couldn't find it so I cleaned everything and started the truck, set the hand throttle to high and climbed under it with a flashlight. I Looked around and finally saw where it was coming from. There is a horizontal hole on the base of the fuel pump that the oil would pulse out of. It seemed to do it every few seconds. So apparently it's bad and be ordering a new pump and get it put on!

Thanks for all your suggestions.
