I suspect cylinder scoring but I’ll only know after the teardown.

Since I only paid $1500 CAD for it (about $1100 USD), I am willing to put a fair bit of change into the repair/rebuild.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Having missed the RND rebuilt (by minutes, I’m sure) offered by LN Engineering recently, I’ve decided to go out on a limb and have purchased a 3.6 which runs but has a knock. Since I only paid $1500 CAD for it (about $1100 USD), I am willing to put a fair bit of change into the repair/rebuild. I suspect cylinder scoring but I’ll only know after the teardown. (Oh yay, I get to produce another YouTube video for my channel!).
I’ll keep you posted.
Congrats. Looking forward to this.

It probably takes about five to six months to have LN install Nickies, as I am finding out. Hartech is a company that will replace just 1 scored cylinder or one bank, if you only need that and want to stay at 3.6 liters. Dayton Sleeves makes sleeves for the M96/M97 3.6 that are ductile steel or cast iron, and there is another company who installs cast iron cylinder sleeves in the M96/M97 engines whose name escapes me. I went with the Nickies, there is some controversy over cast iron/ductile steel cylinder liners for these engines. Looking at the price for OEM Porsche piston rings, the cost of the Nickies didn't seem so horrible.
They use one of the best platers in the country for the cylinder bores, and that plater does lots of engines for cars, motorcycles and snowmobiles. The plating is done after the block is machined and the cylinders are inserted. Hope you're lucky and you don't need it!
Pulled the filter. Some small metal bits were hiding in the pleats. I expected as much.
LN said 6 or so weeks turnaround for the sleeves and nickies if I send them the block halves.
