The later style elbow hose coming off the oil separator has a check valve in it. Anyone know of an elbow the same size and length, but without the check valve thingy. I just learned the the metal combo-pipe under the intake is different on early and late cars. I knew the elbow hose was different, but assume (wrongly) that the pipes were the same.

I am running a hose instead of the combo-pipe now (since I don't use the cycling valve), and spent half the afternoon grinding the unneeded cycling valve pipes off a spare combo-pipe -- only to learn the pipes are different shapes on later cars and that my 86-style elbow hose won't reach the 89 style oil pipe. Doh!
