I must check mine, never done, with a spray of fine oil or hi-temp exhaust grease?

I just replaced my BRV's the old ones were fine, I went to lubricate the VTG actuator. rods and found the passenger side disconnected and laying against the exhaust.

Still having an issue with boost loss at the top end under hard acceleration will need to to a full leak test next. Builds normally until 4,000 then drops out almost like a loose hose or bad seal is intermittently losing its contact or seal.
On the freeway I can gently feed power in in 4th,5th or 6th and boost gets up to 12PSI.

New kit on left the old unit was fine. not sure what the blue and yellow paint signify.

boost leak test completed found one small leak behind the oil filter housing any thoughts on how long pressure should be held? dropping (1) PSI every 12 seconds. no other hissing noises.
