When you say tubes, are you referring to the hoses coming from the exh. valves to the solenoid ? If so, it's possible to have some oil residue in them as they are exposed to gases below the bellows.

there will be some oily stuff in the hoses (tubes) as the pressure hole dealie in the cylinder allows oil/fuel/combustion gases to travel into the valve stuff and then out the hoses. This is what causes the spooge to accumulate in the engine compartment. If you drive WOT all the time, no oily stuff moves through the hoses as the valve/solenoid is closed. At part throttle when the solenoid gizmo is open is when exhaust stuff flows through the hoses.
Oily stuff coing out the top of the valve cover means the bellows is kaputt. Oily stuff all over and exhaust noise from under the hood means the valve attach bolt has unscrewed and the $5 gasket is fubarred.
I just picked up a used pro. Seems to run fine, except from 5300 to 6000 ish rpm, it sounds like the carbs arent sync-ed . I know its efi, but that is the best way I can describe it. I pulled the exhaust valves, and they didnt have much carbon built up, just a little oily. From around 6000-6300 she cleans up and runs great. I'm just trying to get the mid range cleaned up. Any suggestions. Again I thought it was the valves not opening at the same time and rate, so thats why im trying to post this here. Any suggestions helpful.
Are the exhaust valve gaskets the same as the IQ gaskets??
I'm assuming they are.
Every 500 Miles.. Is not over Kill!
It is pretty easy work after the first time.
I want the POWER!!
And Snap of Clean Valves
Run amsoil intercepter and you will never have to clean them again and it is cheaper
