Have you inspected;

Spark plugs for oil contamination and,or, spark plug tubes for raw oil?

Spark plug tube seals, valve cover gaskets (applying FIPG where required) and sealing washers.
STAY WITH OEM PRODUCT

#1 and #2 oil pan FIPG (form in place gasket)?

Oil pan drain plug and compression washer? OEM...?

Oil filter extension housing to block rubber gasket?

Oil level sensor (not pressure sensor) rubber seal?

Front and rear crankshft seals?

Camshaft seals?

Half moon-shaped aluminum wedges residing at each end of head where cam boring machinery machined head cam bearing surfaces? Use Toyota FIPG.

Valve stem seals? Probably rock hard after 25 years.

That is a very in-depth list thank you.

I've checked the oil pan front to rear and it doesn't leak. Same goes for the drain plug and oil filter.

I haven't checked the top end. I'll have to inspect it asap as it seems to be a common leak.

Front and rear main seals seem intact as I see no signs of leaking up front and the tranny fluid/trans itself is clean and dry.

As to valve stems, it doesn't puff smoke on cold starts so I hope that isn't the case though I could see that being an issue due to age.

I have a ton of stuff to go over this weekend!
