Hey Jake, was the 964 engine block bead blasted? It's sooo clean. This photo also shows a superior IMS design.
It was prepared int he manner that I prep every engine that I build personally. I soda blasted the case, then used an aviation clear coating made for engine components to keep the raw surfaces from corroding. After this one is done I move onto a 996TT engine that I'm prepping in the same manner.
I spend more time prepping and cleaning than most people spend on a whole engine. This 964 has about 130 hours in it to this point. That's not including the time I spent in sim configuring the combination, or the time spent on the flow bench with the heads.
I've been spending more time in the engine room over the past few months.
I love soda blasting (but not the mess though)! I did that to the engine case before sending it to Charles and later did that to the engine heads too. Basically anything that can be washed by water you can soda blast. I love the fact that soda dissolves in water so nothing gets lodged inside the engine. However, I still could not remove the dark freckles on the aluminum alloy. Not sure if I didn't use enough pressure or soda blast just can't do that. The freckles look like corrosion embedded deep in the metal.
I feel the same about cleaning. My rebuild project has turned into a restoration project haha

There's always some spots that soda won't get.. I have plugs for all the ports in the engine, so in that case I block everything off and hit those sports with fine media... Then it goes through the ultrasonic at 165F for about 2 hours, get's flushed 2 dozen times with carb cleaner and 180* water to remove anything from the internal passages.
It all takes time.. That what people don't understand when they see a price tag...
The "right" way always takes (a lot of) time. Time = $$ It's really not difficult to understand. Those engines are works of art BTW ! Wow...
"But that engine, it cost more than my car is worth"...
Yeah, its a Porsche, its been that way for the last 60+ freakin years....
The difference with the engines that I build personally, is the car is always worth a lot more than the engine...... I get bored with the normal stuff really fast. Until my new 9A2 engine arrives to be taken apart I won't have any fun with a modern Porsche..
Here's the 996TT all laid out, machined, and ready for me to begin assembly next week... It came in with 6 bent rods. Some idiot with a computer, that didn't know the 4 strokes of a 4 stroke engine got his hands on it.. 40K later......
Ah, that makes sense. I think soda blast is as best as I could do at home then.

no pics but got the new oil pick up tube and internal aos's in tonight. going to clean the oil pan lid 1 last time before applying drei bond and closing it up. if the head studs are in, the heads will be on tomorrow and I'll snap some more pics then.
the primary oil pump has 4 stud bolts, correct?
the stud bolt thread lengths are not equal. looking at my old pictures, it looks like the shorter length threaded end goes into the block, can anyone confirm? also, is there a washer/gasket between the pump and block for the lower stud bolt? theres gaskets between the other studs so figured a washer or orin may go there but I don't see it with my old parts...
I thnk you are correct. I also remember there are lots of threads on the pump side of the stud even when the pump is not removed yet. There's no washer on the lower right stud. Here's my photo.
applied a bead of drei bond and bolted on the sump cover. that's a LNE magnetic drain plug.
new primary and secondary oil pumps, LNE Hex drive behind the pump:
and new timing chain guide rails on both banks, thanks Ahsai for the tips on the rails...that got me going in the right direction
