PCV Valve in the rocker cover BFH code...help pls
Posted 12 November 2020 - 07:17 PM
Unlike other 3.2 R32 engines I'm struggling to find a repair kit to replace the PCV valve in the rocker cover for my engine code (BFH).
Can anyone help with this?

The MK5 has the PCV pressure regulating diaphragm in the rocker cover and the outlet is connected to the vacuum side of the throttle body.
the MK4 is on the "atmospheric" side of the throttle body, and doesn't have the diaphragm. It just has a basic oil separation system in the rocker cover (glorified pot scrubber to condense the vapours). There may be a leak somewhere though.
Did you replace the entire external pipe? There is a valve is the little crossover pipe.

Thanks for the info, very much appreciated!
so no need to hunt for something that doesn’t exist ( the pcv valve in rocker cover I mean)
I’ll check out those pipes when I have a minute.
The rear exhaust is blowing a little ( corrosion and unfixable really) would this have anything to do with my issues of a flat spot around 2500/3000rpm?
She likes this cold weather from start and then the flat spot appears again when warm....lasts a few miles
