05 Toyota Camry engine pressure

...okay, how did we deduce this is an "engine pressure" issue here?

have you had someone run a compression test?

how many miles are on this engine? have you looked at the fuel pressure regulator....to be sure it's still regulatin'?

Blown head gasket can cause higher than normal crankcase pressure. But as stated above we are just guessing without a little more info from you. Where is the pressure to high? How can you tell?

mmmm Debbie, you're letting the best GURUs down, here babe~

are there oil leaks at the Valve Covers?
