However, still no issues with my EBS after 4.5 yrs.

I agree, good points all. One of the doors on my EBS unit was binding on the edge of the mounting bracket when tilted certain directions. I was able to grind a little off the edge of the door to fix this. When fitted into the engine that same door was binding a little at its hinge due to a slight torque on the unit due to the fit. I scoped the EBS after installation and an oil fill/drain (luckily it was the drivers side flap which I could see with the scope). The door was still binding a little so I decided to go with the FVD rather than continue with fitting mods on the EBS.
At 109,000 miles / 15 years the oil flaps, mounting tabs and baffle still looked like new on my original pan and baffle. No deformation or cracks of the flaps, flaps still very pliable. I realize this is not the case for everyone however. I think the EBS would have been fine if I had went ahead and resolved the minor binding issue. I did confirm with Rhonda at FVD that their rubber flap compound was spec’d for this app.
