Hey everyone. Looking for some feedback from anyone who has gone through the oil consumption test/battle with their Ford dealer and has had or not had their engine replaced and specifically what ended up happening once you completed the test that in fact confirms excessive oil consumption. I took my car to my local dealer a month and a half ago and despite them feeding me some BS several times, it was finally confirmed my car was consuming an excessive amount of oil.

One week ago the dealer called me to confirm that my car was in fact consuming oil excessively (to the tune of about a quart every 200-300 miles or so from my observation). They stated that they needed authorization to start the tear down process on the engine and that they'd inspect the inside, photograph it, scope it, and send the results to Ford for approval for an engine replacement. They also ended the call by stating that if they open it up and find nothing that I'd owe them for 25 hours worth of labor (by their tone on several of the visits they seemed to be insinuating that the car couldn't possibly be using as much oil as it was using and I felt like they were trying to scare me as if I were somehow draining oil or tampering with the engine in the process). I was somewhat put off by that statement but confident that something is in fact wrong, I authorized the tear down.

Fast forward to last night and they call me and tell me that "Ford wants them to change out the PCV valve, and have the car driven another 300-400 miles to again check for oil consumption." This is where I'm finally at a trigger point here after all of this. From what I've seen on these forums over the last 3-4 years, when folks bring their GT350s in with suspected oil consumption issues, and its confirmed, their dealers are borescoping the engines, and Ford is rather promptly authorizing replacement engines.

Has anyone out there had their dealer try to swap out other things and continue to test after oil consumption has been confirmed via the standard test? I feel like I should just tell them I want my car back and go to another dealer but having a basic understanding of how the PCV system works and the symptoms of a bad one, it seems like it might make some sense that this is a possible fix but then again, I guess we'll know when they change it out because it will either stop eating through oil or the dipstick will be dry again in 400 miles.

Original powertrain warranty is still in tact until June of 2023 and I have a Ford Extended plan covering it for another 5 years and 48K (expires 9/27/27 or at 59,664miles, currently sitting at 13,500) so I'm not that worried about it, its more that I've been under the impression that other folks who have had consumption issues have basically had their engines scoped and replaced right away (sometimes within a week or two) and this process has been going on for a month and a half.

I haven’t gone through the ā€œprocessā€ but what you describe as what others have gone through, it’s pretty spot on.
Eventually Ford will begin to make it harder to get a new engine, I pray this is not that time.

Yeah I hope so too. It just always seems in these replacement threads that they basically zip through and give an engine out. If the engine is good and the PCV valve is the culprit that’s fine, I just never hear anyone else describe any sort of other potential fixes other than ā€œI got a new engine quickā€ so I wonder if that I’m only getting half the story from the experiences I read on here.

When I had mine done in January of 2019, I had to do two separate 500 mile drives after they filled it up. Then I took it to them to see how much was consumed. It was using 1 quart every 125 miles. They did not make me pay for a teardown or anything else, and did not want to open the engine. They borescoped all the cylinders and tested the compression and leakdown for each cylinder. After that Ford authorized a new long block.

From what I have read, your story is pretty normal. Let them do whatever they want as long as it is covered under warranty. If they start making you pay, then that is where I would start pushing back.

I'd suspect you end up with a new engine eventually. Ford just as to go through all the right steps in order to get you one.

One thing I am curious about. I have been reading up on oil and longevity, and it seems the Motorcraft breaks down relatively quick compared to other brands. What oil are you running? How many miles on that oil change?

Thanks. Hoping I get a call back today and we’ll see what’s what. I appreciate the feedback. If they tell me it’s fixed post PCV valve swap and it’s still doing it, I’ll just take it somewhere else and start over there.

My dealer was Koons in Falls Church Va and they never mentioned anything about the PCV valve. All they have to do is document the usage and send it to Ford for approval. I’m wondering, now that it’s a few years out of production that the supply of spare voodoo engines is almost gone, given how many they have replaced. I’m betting it’s going to get harder to get a replacement and that Ford will be quite happy when the warranty period is done and over on them.

I’m running motorcraft per the book. The oil was brand new when I got it and then brand new again 500 miles ago after they changed it for the first test. And they’re changing it again now as part of the second test. So it’s been fresh every time

That's good info/datapoints. Any chance they did an analysis when they changed oil? If they did, I could see why they started with the PCV stuff. Especially if they did a compression and leak down and it came back within tolerance.

I’m expecting a callback from
Them today so I’ll check and see if they did a compression and leak down test on it prior to Ford telling them to swap the PCV valve or if that was directed separately.

Well they have at least 11 more years to worry about it.

True, but I doubt they have enough spare voodoo engines to last that long. I’m guessing at some point when the spares are gone they will just give a cash settlement to people.

Who truly knows how many engines Ford is sitting on? If someone has information beyond speculation please chime in.
Correct me if I’m wrong…How does a cash settlement under warranty make one whole again? Seems like Ford would loose that battle.
I’m not a lawyer and don’t play one on TV. If someone knows the laws that pertain to this please chime in.

It doesn’t, but if they don’t have anymore engines left, then what? They won’t start a new production of them. You can’t even buy them today as a crate motor. I suppose they made enough to cover things for a while, but they replaced lots of them already.

I'll take the Aluminator once they run out of Voodoo's, please.
