The discussion on the the oil pump wet rubber belt here and especially here is interesting, and does not inspire a lot of confidence

I watched the teardown video this morning. It's my Sunday morning tradition, with a cup of coffee.

I was wondering if the 2.7L in the Bronco has this stupid design.

I was wondering if the 2.7L in the Bronco has this stupid design.

see part #26

I don’t know that the variable displacement oiling system on the Bronco should be classified as a “stupid design”, but admittedly only time will tell if it proves to be reliable or problematic.

Unfortunately, have seen some oil pump/wet belt issues on 1.0L in the EcoSport.

FWIW, I have not seen problems with this design on the F-150 which has been in use for years. Now the 1.0L eco-boost in the EcoSports are another story. Have seen several of those with oil pump/wet belt issues.

It's good to hear that the F-150 has a good track record with it, I just don't see the wisdom in putting a rubber belt inside an engine that needs the entire front of the engine removed while using chains for the rest of the timing system. If it was all belts, fine, but why mix them? What's the service interval on that belt before it fails and requires replacement because you suddenly lost oil pressure? Also, what happens when you're under boost, the belt snaps, you lose oil pressure, and burn up your turbos?

I just don't understand the wisdom here. Cost savings? Lower rotational mass?

To my knowledge, there is no service interval. It is presumably intended to last the life of the engine.

hell, according to Ford you don’t even change the coolant/antifreeze for the first time until 200,000 miles!

I'm an accountant, but I really dug this.

I just don't see how this doesn't need to be replaced at some point. Did you see the condition of the belt after he removed it?

How you going to get to it?

Unfortunately, have seen some oil pump/wet belt issues on 1.0L in the EcoSport.

This is usually due to tensioner failure on 1.0's though, not because the belt is in oil (although that probably doesn't help)

I don't think I've seen any Ecoboost (2.7/3.5) oil pump belts fail yet, and they've been out for a few years now. So hopefully there are no long term issues.

I made the mistake of watching this video. It practically made me feel sick. I know that as vehicles get newer, the chances for a home mechanic to be able to repair anything gets less and less, but it seems like Ford made this engine as complex as it can be.

As a person that has had to tear into my Jeep 3.6 engine, all I could think about is for the first time in my life, aside of maybe changing spark plugs .... all I can envision is now being forced to throw tons of $$$$ out the window because only a professional Ford Ecoboost mechanic will be able to fix anything.

No wonder they have to pull the engine just to work on it.

If you suddenly lose oil pressure while under boost, the turbos will be the least of your worries.

Oh, I know, but it's a concern. If you're putting 6 PSI through the turbos and suddenly lose oil pressure, pull off, and shut the thing down, you're probably going to be ok. If you continue to drive it for any length of time, you're probably going to end up burning up the rod bearings and potentially sending metal flakes through the engine.

Watching Eric's tear down videos for almost two years has made me kinda paranoid about that.

You have about the same chance of getting into an accident and totaling your car out that way as you do with an major engine failure.
