Do I need a new motor?

[rottmore]

Let's say I have to get a new motor and I find a 2022 3.0 6 port. Will that link right up? Do I have to do anything with DME? Or will need anything else?

I'm not entirely sure. It definitely would need a retune. I'm sure @razorlab would know alot more on this.

I would just get another 2port since you're not going to be pushing crazy power.

Saw this post on Facebook - guy is selling a two port head. May or may not be of interest to you.

I also wonder what caused this. I'm not hard on the car. I stay up on maintenance. I don't get it.

BMW makes thousands of these engines a year, and overall it's a great platform and very reliable. That said, last year the B58 in my wife's new X5 dropped a valve at only 7000 miles. Seven thousand. It annoyed me greatly*. It pissed her off so much that she traded in the car after they fixed it.

* - I was driving it when it happened, fortunately stopped at a light when the engine made a loud "bang" and died. Imagine if that had happened while she was driving to work on the Interstate through the construction zone that she has to go through... 70 MPH with no shoulder, nowhere to pull off, with a dead car and no power assist to the brakes, in rush hour traffic.

True to form, can't see shit with that insanely expensive Snap-on tool.

What are we looking at there?

It's a given the head has to come off. Once it's off you can rotate the crank and move the pistons to check the full length of the bore with your own eyes. It means it takes more time if you have to revise your plans after the car's getting disassembled, delaying the decision on needing a block or doing any work on the current one, but you'll get in there with your own eyes,

Yea thats what I'm getting, I just need to tear it apart to see what the plans going to be

Yea I remember you talking about the snap on boroscope even my work said those are horrible pictures. Just gonna have to tear it apart

I'd be much more concerned if dozens of the same gen X5s were dropping valves.
My Supra was leaking out from the left side diff output shaft before there was 600 miles on the odometer. Since I've never read of another MKV Supra having had the same failure, I'm not concerned about poor reliability in the future.

This is the optimal way to drive on E50 - as the heat generated by the constant load will often burn off any moisture in the oil caused by the phase separation properties of the E50.

The guys who run ethanol but only take their car out on the weekends to a car meet or a grocery store are the ones that end up with blown engines :/

how accurate is this? You're describing me exactly. I only have like 18% ethanol blend as I put 2 gallons of flex fuel mixed into a full tank of 93. I run map 2 with my JB4. I drive on weekends and around town after work for fun. Am I truly at risk?!

zero need to worry with that ethanol mix. Even higher mixtures you don't really need to worry about unless you park on the beach or something.

If the car sits for like a year, sure.

I just had my car parked for four months in my garage over winter. Drained the oil. No oddities or seperation. I have posted enough oil sample tests on this forum to back that up.

People blow the whole ethanol "issues" wayyyyy out of proportion. It's just fear mongering.

I've been using ethanol for 17 years now.

That’s a pretty small amount of ethanol, I wouldn’t be concerned.

Here’s a good video from a respected honda builder named Mike Kojima. Super cool guy and knows his stuff. He talks about some of the problems he sees with ethanol.



Engine Masters also has multiple videos on ethanol and get pretty in depth with it. (Sorry don’t have links to those videos). If you have access to that series, highly recommend.

you think if he deglazes cylinder 6 and move up to a 50 weight he can avoid oil consumption issues?

LOL

Now that you flipped it, that does look like a valve up top with an interesting portion of it seemingly torn away. Then you have an area where the compression ring never quite makes it, followed by where they do. I want to call that honing crosshatch but i don't think that's what they actually do at the factory (or, is it?). There's a specialized electro something process needed and not your normal Sunnen hone you'd use on something a lot older. There does look like some scoring but it's past where the rings ever go, so...?
