Sorry if this has already been discussed and resolved.
Here's the story and issue.
FP Black DBB MHI Housing works perfectly fine on Evo 8 stock block @27 psi with Gen 2 oil feed kit from OFH

New 2.4 build and FP black does not smoke at all on cold startup and up to 100 psi of oil pressure,
now once car gets warmed up to operating temps I'm seeing about 40 psi of oil pressure idling and the turbo then begins to smoke! What could my issue be?
i don't want to just feed my turbo to the cylinder head to see if it fixes the issue... Just want to here from others first with the same issue that is now resolved...

 

Does your oil line have a restricter in it? for a ball bearing turbo you don't want to have much more then 40-45 PSI at max RPM.

I run my turbo oil feed from the head. Haven't had any issues (on BB turbos anyway).

 

I have the FP Gen 2 kit that comes with everything... Now my new motor has balance shaft delete( using GSC shaft) and oil cooler deleted for now.. I'm seeing 40 psi at just idling! But the turbo has no shaft play and doesn't smoke on cold startups

 

are you using the stock pcv system? Catch cans?
