AT in engine number

Boy this has gone way off tangent.

They actually DID take the time to come here asking for information, and I wanted to make sure they don't walk off with the misconception that the AT engine is always exactly the same. It's not. Even you, in a roundabout way, have admitted that.

Not everybody has the resources to look up engine serial numbers. Not everybody even knows that they SHOULD, especially for certain procedures, and specifically for the IMSB.
That's why this forum is here: To INFORM people, not misinform them.

I thought my AT engine is the same as the original because I believe I've read on here that they are. It's not. And I don't want them to make the same mistake I did.

As I said before, I don't want to argue with you. Peace.

Fine. I think we all see your point. ...but why do you own a fire truck?

You're talking about parts matching, and that's an important and valid hint. The stupid thing about these AT-engines is that the standard parts catalogues may not be valid. The only good thing is that you (mostly) get an updated unit in parts. But there can also be weird things in these motors, I am quoting from an engine rebuilder:

"Due to production problems, the first 2.5 litre boxster engines had some engine housings in which the cast-in Lokasil mouldings were mechanically removed after casting. New cylinder liners were then shrunk in. Some of these engines subsequently had problems with cylinder liners shifting downwards towards the crankcase. At some point, the liner had moved so far down that the top piston ring jumped behind the top edge of the liner. This of course led to
engine damage."

Exactly how my engine fell apart. It's kind of off topic, because these engines (mine at least) did not get an AT number.

On the other hand, I have an AT engine from a Boxster S which has the non-servicable IMS bearing, and thus definitely different from what it came out with from the factory originally. So, Piper raises a valid point.

I didn't know I wanted one until I saw one for sale.

I just use it for parades, but I used it a lot during the pandemic for neighborhood kids' drive-by birthday celebrations.

Great. Now we get to have a flame war over the FACT that it’s painted the wrong damn color! :-)

[997_986]

But it would be a great color for Boxsters, so still in topic!

🤣🤣🤣

Actually, the real flame war will be about which color it is. Some say it's green, others say it's yellow. What do you think it is?

Or...... how about which oil to put in it? 😜

I simply think it should be RED!

I hear ya. But many fire trucks aren't red anymore for one reason or another, mostly because Lime Yellow, AKA Lime Green, has better visibility.

BTW, I shared your opinion, but this grew on me and I now prefer it over red.
