of course, if you guys want to run a group buy i can organise pricing - email me at work though, it's ryan@regal-auto.co.uk
the BSH PCV fix stops the gunk from entering the inlet manifold by removing the PCV valve - and so stops it from clogging up the back of the inlet valves....
now you still have the crankcase breather, and you still have the rear PCV. if you want to go one step further like i have you can also fit the catch can - this removes the last of the oil and water vapour from the breather system and cleans it up even more.
i've certainly noticed a difference in how clean the bottom of the rocker stays with both just the PCV valve and the catch can
