Engine Cover

Somewhere along the way since 2015 when Ford introduced the Transit vans in North America they stopped including an engine cover on the EcoBoost 3.5L engine. Odd decision because the same engine used in F150 trucks always came with a cover (still do even with the 2nd generation EcoBoost).

Reading enough on the bible site, you learn that there's enough water leakage around the hood on the Transit that the top side pockets in the engine can fill with water and just sit there and start to corrode things. Plus the fuel injectors are pretty noisy under the thin hood.

The recommendation is to source a first generation EcoBoost engine cover from an older F150 off eBay and add it to your Transit. Reading further, adding a 'catch can' / oil separator to the PCV line helps avoid carbon build up on the top sides of the valves. Again, with advice from the bible site, I called J&L and asked if they could make me the older style oil separator which mounted much further to the side than the current version. The older version fit well with engine covers, the new one doesn't at all. They were able to do that at no additional cost.

The first engine cover I bought off eBay was broken in a subtle way that was hard to discern in the pictures, but obvious once you tried to mount it (the mounting pins were sheared completely off).

Got a refund and bought a second one and all is good. Added a couple of patches of Kilmat sound deadening to the underside of the hood.

In the third picture below, the oil separator catch can is in the lower left - it says OSC on it and is connected into the PCV hoses under the cover.

If you add a cover, you'll want these parts - I ordered from oemfordpartsdirect.com.
