MY2018 GT350 - Engine replaced with Gen 1?

[IainD90]

Hi everyone,

I'm picking up a used 2018 GT350 in a couple weeks and I couldn't be more excited. It's been a dream of mine for a long, long time to own one of these things.

I've done my homework with regards to engine failures, and all the unnecessary hysteria surrounding the topic. Unfortunately, the previous owner had to deal with an engine replacement which was performed in May of 2019 at ~5000 miles. The new engine has only around 1000 miles on it while it's waiting for me to pick it up in a couple weeks.

The only thing is, the engine was replaced with the Gen 1 version... Is this normal? I would assume they would replace it with the newer Gen 2 version, but I checked the nameplate on the engine and saw two builders.

I'm not necessarily concerned at all, I'm just wondering if that's normal for them to do. Powertrain warranty is active until March of 2024, and B2B will be extended to 2026.

In any case, words can't describe how thrilled I am (and my wife believe it or not) to have one of these in my garage soon.

The builder name plate would be the one from the original engine, they are not on the replacement but transferred from the old to the new.

Oh, is that so? Good to know. So if it was replaced in mid to late 2019, it's safe to say it's a Gen 2? Are there any other ways of confirming it besides the name plate?

The replacements are long blocks (i.e. block and heads); the rest of your original parts complete the engine (provided they don't need replaced as well).

Pull the coil cover on left side and the engine tag is toward the rear. Has a build date on it.

I see. From what I heard from the service manager at the dealer, the car came in 6-7 times over the span of 6 months for oil leak issues, fuel pressure issues.. and he just said "yes the engine was replaced" but was hesitant to give me any other details. Here's the information from OASIS:

I ordered a vehicle history report and had a friend check OASIS. The vehicle history report (Carfax) doesn't have many service records after the engine was replaced, so I'm guessing everything is new. Pistons etc even (I hope).

Yea, the long block has everything that would be contained inside the block and the heads are complete. That is all new stuff, well, I suppose some of it could be re-man items.

That's a lot of Canadian flags on that page neighbor

"Gen2" engine will look like this when you pull coil cover on the driver's side

Yes sir! Hey I got the same colour as you.

See my updated post above with the pic from my 19MY engine.
