I know what I will be working on...

Not 100% sure where the oil is coming out. From the time I smelt it happening to the offramp was ~2 miles. Oil pressure was fine and it still turns over and runs smooth. It's coming out with enough pressure to spray all over and hit the fan, which distributes it everywhere else. I'm guessing an odd head gasket or a timing plate leak? Olly tossed it on his trailer and it's a future Kurt problem. I built that motor in 2021 and it's been uber trouble free since then... guess it wants some attention. 😄
Update. Finally had a minute to tinker on this. Olly (
@Cruiser) stored it at his casa after fetching it off the highway. I was out of town and didn't give it a second thought. A month or so later we got it back to my house and did a quick car wash blast off before rolling it into the shop. There it would sit for another month.
Today I started hunting around for a leak and couldn't really see a culprit. It was pressurized so I thought it was coming from behind the timing plate as there is a galley there that sprays oil at the timing gears. I decided to toss a gallon of oil back in it (it was 4 qts low), remove the fan belt so it wouldn't spray all over and probe around. Low and behold it's a oil galley plug aka welch plug. It was installed by the machine shop in 2001 so I can't complete about its lifespan.
It may have been weeping before as could see evidence of dirt/oil behind the crank pulley but not enough that it dripped on the floor. The fix should be straight forward, a new 24mm plug OR I may tap it and use a plug, that's how the later model Toyota 2F motors were. I yanked the radiator, fan clutch and blade and shroud so I could access the plug.
