MG TD TF 1500 - Crankcase Ventilation

There is link to a rather interesting articlein the MGA forum ( https://www.mgexp.com/forum/mga-forum.2/mga-crankcase-ventilation-test-results.4476585/ ) that gives me pause to wonder whether my rocker cover vent system is working. How have others who at using pancake style air filters accomplishing RC ventilation? Thanks. Jud

There are a couple of threads on the US Forum on this very issue for the T series, involving consideration of the MBG PCV system. A more recent development is to use a system to create a venturi effect using exhaust pressure to vent the crank case. Early tests seem to show promise as this does not affect idle-related variables.

Because I have had good results from the Smiths PCV system on other BMC cars, I retrofitted one to my TD. This causes a slight vacuum on the crankcase and my car is amazingly oil leak free perhaps because of this.

No impact on your idle John?

Been a long time since I fitted this but I might have adjusted it slightly at the time.

Lonnie, you might find this thread interesting. In my humble, VERY non-expert opinion, you're OK for your planned trip.
