Does my 93 have a GM engine?

[Dr Doofenshmirtz]

I bought a SAAB 93 2.0t which is in beautiful condition, and then started reading all the SAAB sluge nightmares on 'tinternet
I was about to drop the sump and check for sludge, then realised my sump looks nothing like most of the internet guides.

Then I read that SAAB switched over to GM engines in 2003. My engine looks like this:


So is that a GM engine?
I guess these don't suffer sludge like the SAAB engine used previously>

The sludge issue was only with the 9-5's to 2002/3.
Yes, it's a Vauxhall engine - improved by Saab for better performance and economy (this was one of the things GM wanted, and did, steal, as their own 'intellectual' property.

No SAI on yours, I see, which is good news.

Thanks.
What is a SAI?

Sludging also affected the original 9-3 as well. Best way to avoid it is to buy an Aero with good service history (so you know it's had the right oil used).

I believe Saab changed the ECU programming quite considerably, and along with a few other tweaks to the engine. Just enough changes to confuse a GM mechanic :-)
