from what I am reading ,to remove the cam covers(rocker covers) on your bike will mean the removal of the engine mounts to allow for enough room to get them off

Well, there is an "umbrella valve" in each of the center sections of the rocker box. These can and do get brittle from the repeated heating and cooling. They do a good job of keeping the bulk of oil out of the air filter but they can't get it all. As will all previous Harleys, they blow a bit of oil and those that relieve their crankcase pressure into the air filter do still make a mess that must be cleaned out occasionally. But, it shouldn't be excessive. Excessive blowby on the rings can exaggerate the problem.

To replace the "umbrella valves", simply take the bolts out of the rocker box cover and replace the gaskets and the valve. You will have to pull the fuel tanks to do this job.

Good Luck

If the crankcase pressure is too high due blowby on the piston rings, you may in for a upper end refreshing. Or, it simply could be the "umbrella valves" in the rocker box covers. You can remove the four bolts that hold the rocker covers on and replace the umbrella valve in the center section. That may cure your problem.

Good Luck

no you do not have to take the engine off the frame. all you do is remove the gas tank and seat disconnect all wiring to the engine take the carb off and unbolt the rocker cover of the cyclinder that has the blown head gasket then unblolt the head replace gasket then reasemble in the reverse order

Accelerating at what speed and gear?????????

take the rocker cover back off and check the oil breather and make sure the o ring on the bottem of it is still on there
