Change Oil Pan Baffle - Good Idea or Not?

[Oldcarguy]

After trying the EBS “deep” version baffle along with the .5qt sump extension, I decided to switch to the FVD .6qt bespoke oil pan and their x51 style baffle. The FVD oil exchange windows are smaller than the EBS, use rubber flaps and are positioned higher in the baffle. The FDV edge seals are rubber wipes rather than the EBS wraparound rubber. No clue whether the design differences are good, bad or a wash but a friend of mine has been running the FVD in HPDE for several seasons with no problems (in a 996). The FVD was a perfect fit out of the box.

Like others on this thread I had to make minor mods to the upper and rubber edges of the EBS to make it fit to my satisfaction. Additionally I was glad to eliminate the double row of flange sealant. I applied the SI5900 using a regular caulk gun with no problems.

That is pretty slick!

That FVD is a sweet looking unit.

Always interested in the flappers and how they're made. Factory and FVD use rubber doors, the EBS uses a metal hinged door. Rubber ages and will crack. Not good. The metal hinge seems could get debris in it and freeze open. Not good. It's probably my paranoid nature with something this important, but each method appears to have potential issues.

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.

With this mod, how is the oil level checked? Does the same oil dip stick work for accurate measurement? How about the digital gauge on the instrument panel?

I have run many deep sumps in every thing from air cooled VWs to big block 455 Olds. The dipstick stays the same. if you changed the mark or extended the dipstick to compensate that would defeat the purpose of the deep sump.

also the same for the digital gauge. Both work as before.
