Early TR4s are like TR3s with the vented oil filler - no vent from the =
valve cover. Maybe you have excessive crankcase pressure due to blow by =
or worn valve guides? Have you done a warm compression test?

Bill=E2=80=99s 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

One approach is to modify the air filters yourself.  Easy lathe project if
you have access to a lathe; or something like this
https://amzn.com/B01C9A386Q
Combined with a NPT to hose barb adapter like this
https://amzn.com/B07TYJMGXJ

This might make more sense with a K&N filter or similar, so you don't have
to keep redoing it every time you replace the filter element.  Here's a
clever approach
https://is.gd/KqiAkQ

Another, less elegant solution is to just attach a longer length of tubing
to that port and let it hang down below the frame rail.

Yet another solution would be to drill & tap the intake manifold, and add a
PCV valve ala TR4A
https://i.imgur.com/nfIpy40.jpg

And finally, you could install a crankcase evacuation system that taps into
the exhaust.
https://i.imgur.com/EKNowxs.jpg  (photo from Joe Alexander)
https://is.gd/HmzoKv

The exhaust port gets really hot, so be sure to use high temperature
silicone hose.

Oops, forgot one:

If you pry out the plug and install the road draft tube from an earlier TR,
then you could cap the line from the rocker cover.

 That filter is a good idea if you're planning on using the road tube to ev=

 breather cap)=C2=A0 and just allowing the blow-by to exit the engine on it=
's own ( with some=C2=A0slight suction from the road tube) has been quite s=
uccessful, no stink, no oil vapors and no oil burning or leakage ( beyond n=
