Smoky Jimny

it gets that ever so often, but I'm 53 years old

Edit: And the nearest local dual carriage way is only 5 hours from here haha. (If not counting the very steep uphill in the under sea tunnel)

If the PCV breathers are blocked, it can do funny things - in theory the crankcase should normally have a small through airflow from the clean air intake tract, into one side of the rocker cover, and out to the intake manifold (lower pressure sucks it through because of the presence of the throttle valve). At higher loads, blow-by increaes crankcase pressure and it only blows one way.

If the system is clogged, oil mist gets forced where it shouldn't, you get oil leaks, or odd idling problems because the metered airflow is no longer correct.

As it's only a couple of hoses and a ball valve, it's easy enough to check and flush with carb cleaner if necessary.

The more I learn about where you live the more I think I should learn Norwegian and emigrate! But then I remember the laws and rules you have to endure when you want to modify your Jimny.
