[TR] TR6 rocker assembly oiling

[fogbro1 at comcast.net]

Don and All,

Well, I installed the external oiler with no improvement. Then I removed the rocker assembly and cranked the engine. Plenty of oil coming up through the hole in the head, the oil feed hole located beneath the rear pedestal.

I am currently of the opinion that the oil is getting to the bore of the rocker shaft, but not to each rocker arm. I have once again (I've lost count) dismantled the rocker assembly and checked that the holes intended to feed each arm are clear.


Adjacent to each oil feed hole in the shaft is a small flat along which the oil is intended to travel to the each rock arm bushing. Each bushing has two oil holes, one aligned to the hole in the top of the rocker, the other aligned to the respective pushrod. There is no groove of any kind within the bushing to direct oil to the two aforementioned bushing exit holes. Oil can just as easily exit the sides of the bushing.

I have an original TR250 rocker assembly which I'm about to examine to see how the oil path(s) is on that.

Any thoughts from the List?

This is day three on this problem.

I wonder how many days like this I've spent on TR's since March 1959???
