[TR] TR4 valve cover

Bill’s comment begs a question or two.  My later TR4 has the valve cover vented to the carbs.  You cannot (at least I have not found any) buy any of the air filters for this system.  How do I remedy this problem?  I was told to NOT plug that vent from the valve cover.  Suggestions?  Jim Mills

Isn’t you valve cover vented to the carbs?  Maybe a plugged PCV valve?  If so, I would think you should not have a vented 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
