I had really aimed for getting this on the road this summer, but as these things go, that is looking less likely.
Yeah, it takes a lot longer than one would think.. Especially if you get lost in the details. What are those coated bearings like?

They look like bearings to me, but I'm not remotely an expert! All I know is they are substantially more expensive than your basic Clivites!
Yes, it has taken longer than I thought. I've been amassing parts for a while, and in fact, noticed a box dated 2020 just yesterday. But there are a couple of factors like a 1000-mile move and a second bad engine, but we'll skip over that.

Joining the cases

I had some progress with the engine in the past weeks (months?), starting with some clean-up. Case halves drying in the sun.



Ready for the crank assembly.



Here it goes.



Chains...



Gapping the new rings.







Torquing down the rod bolts.



Case halves rejoined.

Home made tool to make sure the casings are perfectly aligned. There's a factory mandrel that fits into the bore of the IMS bearing (not the imfamous one, but on the other side, by the oil pump) and holds the case halves aligned.



Pulling out the tool.









The newer Boxsters differ from the base model regarding this circlip. The base model has a simple circlip, while the newer version has a lug that needs to be installed in a specific position making the whole proces a bit more difficult.
