[TR] TR4 valve cover

[Bob Westerdale]

 Make sure your road draft tube is 'clear'.  Other cause could be excessiveblow-by.   I have an '68 engine in my '59 TR3,  the block had a plug in the road draft tube port,  and I wasn't running the  PCV crankcase vaporrecycle tubes,  ( a-la 1968)  so any and all blow-by  ( c'mon, they all do it)  came shootingout the valve cover oil fill cap.

My early TR4 (9,XXX) spits oil all over its nice chrome valve cover from the breather cap

  

Is there anything I can do about it other than clean it often?

  

Btw it has 89 mm pistons, mild cam, polished/ported/shaved head, etc
