Hello All
Last summer I did install a catch can system on my engine, fresh built 403 stroker
It's a Swiftek valley cover with their catch can (see pictures)
I run 2 x # 8 hose from the valley plate to the can itself
When I rev the engine to 6000 rpm, the catch fill up with engine oil and I need to drain it every time
Did some digging on the web but can find a clear answer
Should I put some restriction in the fitting ? or add a hose from the valve cover to breath ?
Any advise will be greatly appreciated
Thanks

You need to plumb in fresh air to your valve cover to replace what’s being taken out. Not sure but that K N filter on you catch bottle might be hurting you in terms of unmetered air source. You should give Mighty Mouse a call and let him set you up proper, he’s an active member on this site.

what does Swiftek say about it?
