Big red valve cover removal ?

[dustrunner]

Is it possible to remove a 250es valve cover while the engine is bolted in the frame ?

[Airmapper]

Yes. Twist it out to the left side.

Copy that left side, it will seem like it's not gonna go and don't force just be gentle.

yes. it will come out. left side. if i remember correctly, the clymer manual says out the right side, but the manual is wrong.
