What have you done to your SVX (or other Subaru) today?

I did discover a wet connection where the transmission fluid feeds into the radiator so tightened the hose clamp.

Also discovered that my head gaskets are leaking.

Peter, I am sorry to hear about your head gaskets.

Head gasket problems are a serious problem. However, it may still be possible to repair it.

Oil leaking from the head cover is not that serious. I hope it's a typo, but...

I'm not a mechanic. What is the difference between a leak from the head cover and a head gasket?

I think he means valve cover gasket.

Yes, Also called valve cover or tappet cover. Since the cylinders of BOXER engines are arranged horizontally, oil tends to leak from the cover. Gaskets are made of a silicone rubber-like material that gradually hardens and eventually loses its elasticity to seal the oil.

This is webpage that someone is replacing the cover gasket.

The head gasket, on the other hand, is located between the cylinder block and cylinder head. This gasket is very thin and seals in compressed air, coolant, and oil. Head gasket damage usually occurs when the combustion gases in the cylinder enter the oil and coolant passages. It will overheat or the coolant and oil will mix and destroy the engine.
There are rare cases where only oil leaks to the outside, but since combustion gas has the highest pressure, it is the most common source of leakage, followed by coolant leaks.

I think what you're probably talking about is oil leaking from the tappet cover, valve cover, or rocker cover gasket.

In that case, replace the gasket with a new one, or even if you can't get a new one, clean it thoroughly and seal it with a liquid gasket and it should stop leaking. Oil line pressure shouldn't be high unless your engine has blow-by problems.
