Bad seals? what do you think is wrong?

ok the engine is a 420a with a T3 garrett on it. we've been running about 7 or 8 psi, not much basically. well anywho somehow the boost controller got f'ed up and bumped it up to about 11.5 psi, which probably isnt to great on stock internals. we got that fixed now but yesterday when my bro started his car it started leaking oil pretty damn bad, as you can see in one of these photos, there is a considerable amount of oil spitting out of the breather valve on the valve cover. we checked all the oil lines/fittings. now we are trying to diagnose what is broke. so what do you guys think? here are the pics.

the whole engine bay


this is that valve mentioned above that oil is sprayed out of.


the turbo set up

Problem Diagnosis forum

Check the oil, see if its milky, if milky and smoke , Im 100% sure you blow your head gasket, cause over boost. And damage the engine internor. Good luck bro, btw you dont have to go to problem diagnosis forum and make another topic, the mod here will move it for you, just post it in right forum next time .

that could be a good idea, idk how much money my brother has right now though, its his car actually. not mine, as you may guess by my name i have a mustang. i like to think im pretty open minded when it comes to cars tho. ill certainly talk to him about that tho, if it hasnt already crossed his mind.

A nice combo of eagle rods and weisco pistons will support up to about 600hp and only run him about 750 dollars. IMO its well worth it. Then he can run a nice amount of boost all the time.
