Well I found the problem. The number 6 connecting rod bearing failed and destroyed the crankshaft journal. Also the rear most crankshaft carrier bearing has preliminary signs of failure from either metal contamination from the rod bearing, or excessive vibration from the rod bearing. It caused some pretty serious scoring in the piston hole, and ya...it pretty!

My ultimate wish would be a flat6 build, but quite frankly it's way out my budget. Now I am on the fence as to whether I should just sell my car as a roller/part it out, or search for a low mileage 3.2 to swap in.

I have read a couple of conversion threads and articles about swapping a 3.4 into the car, but it appears to be less straightforward than I thought. I didn't know there was much involved in the ways of intake plumbing, MAF, DME, trans mount, etc

Is it really worth the hassle, or should I look for a 3.2?

2000 or 2001 996 3.4 is the easiest engine to swap. After listening to the engine run, perform a compression &/or leakdown test to check for excessively worn cylinders since the 3.4 engine has the thinnest cylinder walls. If the engine passes you still need to remove the cam covers & replace the VarioCam actuator wear pads. While you have the lifters out clean & test them. Reassemble the cams & covers & set cam timing. Now you are ready to do the LNengineering IMSB retrofit. Now you should have a reliable engine ready to swap. The long blocks are nearly identical so remove original engine & position 3.4 side by side & swap external parts that are different for 996. This swap will run great without reprograming the DME.
There is a rebuilt engine in the classified thread designed for this application.
