Tell me about oil cooler seals Options

I thought my leak to the front of 4 was the valve cover gasket. Now I am leaning more towards the seal on the oil cooler. Seems to only really leak when the oil is hot.

Unless you have an engine stand, and a way to pick it up once dropped , I suggest you do all rubber and gaskets while it’s in the car

Clean everything
Place cardboard underneath
Find the drip

Pushrod tubes cannot be totally removed in car, but you don’t need to remove the. Just unseat them, change o-rings, reseat them.
Remove rocker arms from car. Put back after, then set valves ( but they will be the same as when removed because nothing has changed)
Vice grips to pop push rod tubes from case and heads.
Leave push rods inside…no need to remove them

Oil cooler seals, we covered
Oil temp sensor, if equipped
Oil sump strainer
Oil pressure sensor
New valve cover gaskets
Oil filler box has a gasket under it also

You mention racing and hot oil.
So higher oil pressure, hot oil, 40 year old gaskets


Remove, clean, new gaskets and new crush washers for all locations.

Aside from front and rear main seals….those are the leakers

I just did all of those, on a lift.
I also redid the leaky transmission shifter console

Not hard, no need to remove engine
I admit that removing the heat exchangers will make some of the project easier, but that introduces more risk with head studs breaking.

This is an annual or every two year thing when racing.

While there, tighten all cv joint bolts….because
