So for a while now I have had issues since swapping to the FF VC and not sure if its because of the lack of baffles inside or the cover on the cap is not great or if its another reason completely so im trying to narrow it down and make it work better for me. While i know collecting it is good its too much too soon so.. here it goes,
I seem to draw alot of oil out the engine (head/VC) in such a short amount of time. And now the cars down for work im wanting to try resolve it as best as I can.
I know the stock system allows air in and from what i read lets air vent from the crank upto the VC but now i have a different cover i dont know if im not letting this air out easy and its pushing or allowing oil to be sucked out of the VC. It could be oils not being allowed to drain back down the block ok.
So i had an idea to make a secondary baffled catch can to run inline with my VS3 unit. But with an added twist and an idea on my can which i dont know if its good or even correct to do.
So from this picture pic at bottom of page (sorry for the jot and lack of precision) i have 2 lines from the VC like normal to the VS3 then im going to add an 8AN on the side in the baffled section to pull from the block (balance shaft inspection hole) this i was hoping would releif the crank pressure and perhaps oil can drain down more freely in the head/block meaning i might not have excess pressure in the head forcing its way out the VC, this is 1 theory i have.
The secondary can would be fed by 1 from the VS3 as it only has 1 exit port and my one can use 1 or 2 ports depending on my findings later on. Now here is what i dont know what to do. I was thinking of adding a pcv valve on the last can right by the intake port back into the intake manifold (actually as i write this im seeing this as a bad idea) as the whole point would be to pump fresh air into the VC and this wont be.
I been reading and looking at this guide for ages trying to figure something out https://www.dsmtuners.com/threads/the-4g63t-pcv-system.366890/
I have never popped a dipstick from excess pressure in the crankcase so i ruled that as a possable but its still in my mind about the piathways and what the stock pcv system does.
I had thought for a while about msking an air / oil seperator and either it being inline with the catch can or it draining back into the pan but since i have no real way of pumping coolant in through it to stop moisture build up i gave up on that idea currently (i might be able to make something work if i had to but not easily)
So has anyone who is more in this sector got some ideas or am i in the right direction to help it overall vs how i was which was VC > VS3 > Intake pipe.
Thanks for reading and hope i can get some ideas from you i can ponder over as i have just about maximised my ideas and i might be missing something or not found it here yet amonst the many many threads i have looked at for guidance or ideas.
Thanks all
Bobby
