    I don't think the builder has any thing to do with these engines having to be replaced. They don't make the parts they only assemble the parts already made.

    Probably get opinions all over the place but thought I'd throw a question out. Does anyone think doing a compression and leak down test is worthwhile if your car consumes oil but not at the level Ford says is necessary for engine replacement before you go out of warranty? Would you feel better knowing they are normal and your oil consumption is compatible with engine design? Would you be more likely to dump the car or get it fixed before the engine blows if it was abnormal? Would Ford fix it under warranty if it was abnormal? At what level would you think of doing this, say a quart per 1500 or less? As there are now cars getting closer to that mileage, maybe some would be willing to do that and post info if they have a "consumer".

    I think that if it’s at 1 quart per 500, which is the minimum...then it will get worse as you drive it more. In my case it was normal use, then it started and quickly got worse. Then I took it in and did two separate 500 miles use tests and they did the diagnostic tests too. It was at 4 quarts per 500 miles and I got a new motor. It’s a process and you have to jump through the hoops which takes time, and yes it’s a bit irratating

    I was more talking about the fact that if dealers are putting the original engine builders plate on the replacement engine. Then those really aren't the the people who built it.

    I just had my engine replaced, #3 and #7 let go. Punched a hole through the block.

    1. I received a new cooler
    2. I received the new sensors
    3. I received a new intake manifold
    4. The KR3Z-6006-B is a 19+ 350R motor. (Confirmed by the Ford rep that did my case)

    There is a name on my engine. I am not sure if its the same name plate that was on the original. I was also informed that the headers and tune I have is in the database and will not effect my warranty going forward. Heck the rep was trying to sale me the extended warranty at the end of the call.

    Thank you for the info!

    Is it recommended I start a case with Ford Service or just work with the dealer?

    That's strange they were trying to sell you an extended warranty. Everything I've read is that you are given the 7 year/100k mile extended warranty.

    I am not sure in your case. I opened a case with Ford because my dealer did not want to honor my warranty because of headers and tune I had. You can read about it in the thread "Add me to the list nobody wants to be on" thread.
    If your dealer is working with you, then work with them. I do not know anything about the warranty you mention. The only thing I received was a warranty for the work.

    In my opinion if your engine is consuming oil I would drive it as much as possible and as hard as possible (ideally get on track). If there's a defect that's causing the engine to consume oil, with time and use the problem will get worse and the engine will consume more oil. If the engine is consuming some oil because the rings aren't sealing as well as they could, hard use on track might reduce the amount of oil being consumed. I'm a firm believer in lots of full throttle and no throttle driving to get rings to form the best possible seal against the cylinder walls.

    No, I wouldn't do a compression/leak down test. I definitely wouldn't pay someone to do it. If you decide to do it just for your curiosity and you enjoy doing that kind of work, then fine. But I don't think a compression or leak down test will show a smoking gun.

    On edit, there is still some time before the power train warranty goes away for any GT350s, At least a year I would say before even the very first GT350s go out of warranty. My advice is to use the car!

    Wonder if a compression/leak down test might be cheaper than a track weekend.:) So you don't think it would show a problem at consumption level less than a quart in 500 miles.

    Will the tests be cheaper? Probably. Less fun? Definitely!

    If the consumption is from a defective valve seal, the tests won't show that.

    If the consumption is from an issue with an oil ring, the tests won't show that either.

    If somehow there's a defect in a top ring and that is causing that amount of consumption, yes a compression test and/or leak down test either would show it.

    Will Ford accept the results of your test and do something? That's the big question I don't know the answer to. I'm not aware of Ford publishing specs for what the compression and leak down should be. It's possible if one cylinder shows really different than the rest you would be able to get Ford to do something. I think Ford is really great in general with their warranty coverage.

    The dealer just got my replacement engine in (2 days from bringing it in is quick). It is a November 2018 GT350R engine (KR3Z-6006-B).

    Called Ford Performance they do not provide replacement engine builders nameplates. They have tried in the past and have been denied by the Romeo Niche Line.

    Well I guess I can add my car to the list. Picked up a 17 with 8k a month ago driven less than 1k was driving normal thru town and it started ticking pulled over as soon as I could. In less than a mile the tick became a bad knock, no cel. Shut it off and it wouldnt restart. Oil pressure, level and temp were normal. Waiting to see what the dealer says. Wonder if I recieve worse customer service from Ford since I did not purchase it new.

    If you do take it some where else. Thats what warranties are for and shouldn't matter whether you bought it new or from that dealership.

    What is Ford's protocol for an oil consumption test? How many miles are necessary to complete the test? I feel like my local dealer doesn't know what they are doing!

    I suspect my 2017 350R is burning oil excessively. I've kept a detailed log of my mileage, driving habits and oil consumption for the past 1,000 miles, and per my records I'm burning 1 quart every 250 miles.

    3 weeks ago I took it to my local dealer to start the oil consumption test. They had no idea about the problem that some of the 350's are having, so I had to explain everything to them. They agreed to start an oil consumption test, but wanted me to drive it for 5,000 miles and bring it in every 500 - 750 miles to be checked. It would have taken me a year to put that many miles on it, so they agreed to cut the test down to 2,500 miles and check it every 500 miles.

    After 350 miles of varied driving the oil level is barely registering on the dip stick (about 1/2 inch below the lower dot), so I took it into the dealer to be checked. Got the call this morning that they found a leak on the passenger side of the engine (they could not or would not tell me more), and said it was down a little over 1.5 quarts. They apparently fixed the leak and topped off the oil, and want me to drive it another 500 miles before the next checkup.

    If they found a leak and it was down 1.5 quarts after 350 miles shouldn't they report this to Ford? Is my dealership doing the test right? I could really use some input from the guys who have been through the oil consumption test.

    Go to another dealer. What they do is for an oil consumption test is....top off the oil....then you drive 500 miles....don't add oil or even check it.....as you hit 500....go to the dealer and they check the level and top it off if they have to.....then drive another 500 miles and check it again. If its used more than 1 quart in 500 miles, its a bad engine. In my case they also did the borescope camera on each cylinder, dye test, compression test and leakdown test.....all the data gets sent to Ford, and they make the decision to replace the motor.

    DCShelby - Thanks for the quick reply. I thought about bringing to another dealer, but the problem is the next closest Ford dealership is 40+ miles away, and i don't have any kind of relationship with them.

    My dealer did the following:

    Changed the oil, added dye to the oil to look for leaks, scribed oil level on dipstick. All I had to do was drive, come once a week to check oil. I made sure I drove over 200 miles a week. At the first reading they looked for oil leaks - nothing. After the third week, they called it - they documented adding 4 qts in about 900 miles of driving. A week later they had the OK from Ford and they sent a new motor (btw new motor built Dec 2018, my car was originally built Sept 2017). Good news is, I now have 3300 miles on the new motor and zero oil consumption so far. My first motor started burning oil after 2500 miles. Fingers crossed!

    I sure hope it works out for you. I still wonder how mine is doing. Did the consumption get worse/better/same.
