Were your exhaust tips coated with excessive sooting?
Nope, there was nothing.

Pre 2018 350 engines had a lot more problems than 18+. It's unfortunate for you but a lot of people have also had 0 issues with their engines so we don't need another Ford is making cars that are ticking time bombs thread. You may come out with an upgraded 19+ engine with the upgrades from the 500 development so it may not all be bad.
I'm not sure that 18+ owners have had their cars long enough to suggest that the 18+ engines are more reliable than previous models, and I haven't seen anything from Ford suggesting your claim. If your claim is accurate then I would expect there to be a major recall on all pre-2018 models, and it would definitely warrant the "ticking time bomb threads" that you mentioned, since that's exactly what pre-2018 models would be in this case. I didn't create this thread to bash Ford, but rather to make the mustang community aware that another voodoo engine has bitten the dust. You can put your fingers in your ears and close your eyes if you'd like, but the truth is no car manufacturer is perfect - mistakes will always be made and there will almost always be manufacturing defects with some cars.

I just hate to see posts about oil consumption bc soo many people on here will start a Ford bashing and it takes away from people who may be on the fence about the car with blanket statements.
Would you rather have people that have to have their engines replaced due to oil consumption not tell anyone? Are you sure that you aren't an undercover Ford employee?

I don't think there's ever been a defect in design of the Voodoo engine that results in oil consumption.
I agree with this. It seems highly unlikely that Ford would invest so much into an engine that was broken by design. I speculate that a decent portion of the oil consumption issues arise from manufacturing defects (like you mentioned) due to suboptimal quality control.

Look at it this way.....I did.....you get a 2019R motor, with all the upgrades. Mine (2018) was at 1 quart per 125 miles when it was replaced at 5K miles. The new motor has over 10K on it and uses about 1 quart per 3000 miles. The new motor will NOT be numbers matching, if that's a thing with you.....good luck. Ford does not and will not stamp the new motor with the older motor number.
I'm glad to hear your Shelby is running much better with the new engine. I hope that I get the same result with my replacement. I'm not really concerned with numbers matching, although it does suck that the engine replacement could potentially lower the value of the car. I plan to keep the car forever though and put well over 150k+ miles on it, so the value I'm concerned about most is the enjoyment I get haha. Maybe I can get Ford to throw in a free 100k mile warranty with the new engine :sunglasses:

I don't have sources off the top of my head ready to paste but there are numerous and I mean numerous threads on here talking about oil consumption and the upgrades Ford has done to the Voodoo over the years. It's really hit or miss if it affects you but all I can say is I have had 0 issues out of my new 19.
And you won’t find any factual sources.

Without Ford publishing the data from ALL cases of excessive oil consumption, you should not making inflammatory statements like, “Pre 18 350 engines had a lot more problems than 18+”.

Forums offer very skewed data.

Your statement perpetuates unproven information.

My engine was successfully replaced under warranty with a 2019 GT350R engine. I've racked up 1000 miles so far on the new engine without any noticeable oil consumption. So far, so good. I've updated my original post to reflect the engine's current status.

Yes, the source please.

It’s funny because to me it seems the 2016’s have the least engine oil consumption issues :)
yes. 2016s were really not much of an issue

Had new a 16 GT350 and 17 GT350
I had a 16 and then a 17. Never tracked them just drove them on the street. Both used a quart of oil every 3,000 miles from the day I took delivery.

I'm in this boat now. My 2018 GT350 used 3 quarts in the last 600 miles during my oil consumption test. 10,800 miles on the clock, no track days, and I did the break-in per the manual. First oil change at 1000 miles, than again around 7500.

FoMoCo will authorize my local dealer to perform an engine teardown in a few days, at which point Ford will suggest to repair or an engine swap. Fingers crossed, I'm nervous, love this car to death and just want it working. I plan on putting 150k+ miles on this car if at all possible. I'll update y'all as my story progresses.

Do you have a pic of the engine sticker?

It would be interesting to know when that motor was built.

Hi guys, I just purchased a 2017 GT350 from the dealer. Turned out after a month of driving I had put in 8 quarts of 5W50 Ford oil in it. Took it to the dealer for a consumption test and the picture attached will explain everything that happened to get a new motor installed in the vehicle. To be noted, Ford will try to get you a short block. You have to find the right dealer and tech to fight Ford to get you the long block assembly which means you will get a new full assembly engine. What also is included is a replacement of all one time use parts such as bolts and belts plus the water pump. The intake etc is salvaged and re-used.
i personally did not go back to the dealer who sold it to me because when I stated the oil consumption problem, they said that read the manual, it is supposed to consume oil. I knew it was consuming over what is advertised, so I went to a dealer that knew better. I built a relationship with the tech who was going to work on my engine and also with the staff. They fought for me and got the whole thing replaced. You can see the effort put in by just the notes from the tech, he knew I got a bad car. Basically, when the VIN does not match the engine serial number, the cars value plummets at the dealer so they cannot sell for a higher amount. On the flip side, the private market people know the value of a fresh 'R' engine so the value actually goes up. So I can see why the dealer I bought it from said I should be happy I got a new engine when I let them know about it instead of getting it fixed while it was in their hands even though it was all done under warranty.

In total, the whole service cost 45K CAD, the engine itself it 32K CAD as priced out at the dealer out of which I said put in a new clutch and slave cylinder ($1600 from my pocket) since I did not know how the previous owner drove it. If he was careful the engine would have already been replaced. thankfully it was all under warranty. The engine I got had a GT350R motor as it is denoted with a serial number starting with 'K' and was labelled GT350R.
Also to be noted, this engine is rated for boost, as its using a GT500 block that uses a supercharger. I will not be boosting mine but I am excited to delete the cats and resonator. Pipes have been ordered and its going to be a fun summer.

I live in Toronto, Canada, if you have questions here I can guide you to the dealer to get you help if you are experiencing problems with your GT350.

Anyone know if starting with a short block is a new Ford practice?

In the past they’d never allow a dealer to open up a 5.2.

Also, I wouldn’t assume just cause you have a GT500 block it’s ‘rated’ for boost..

Well when I purchased it, the dealer did a fresh oil change. After driving about 2000 KM, I noticed the oil pressure gauge was not holding steady during warm up. I got concerned and checked the oil level. Turned out the dipstick was clean. I put in 6 quarts initially to bring it up to level. Drove it again for another few hundred KMs. Checked again and after putting in 2 additional quarts, the dipstick level came back to normal. That was insane.
When I took it for a consumption test, I drove it another 660KMs and lost 2 quarts. So in theory driving it about 4500KMs in total, the car consumed 10 quarts!
Also to note, this was during the winter months, so I was not driving it hard and neither did I take it to the track.
