The Papi Express
In this entry, the S85-001 gets pulled, undressed and gifts some of its parts to the 002. Some are replaced, some are restored, some are upgraded. This is part 1 of 2 documenting the swap process
In this entry, new dishes get put in. We fit the new valvetrain package, finally bolt in the Schrick cams and we go through the VANOS re-timing protocols.
In this entry, the dishes get pulled. Nearly the entire OEM valvetrain gets removed. I take detours to discuss technicalities of hydraulic lifters, and the mechanism of a valve assembly.
In this entry, we finally get the S85-002 on a stand and get to work. The last accessories are removed, the V10 is drained and we turn it over to start with the obvious: connecting rod bearings - with a new twist.
In this entry, I document the current market dynamics of sourcing a quality S85 engine. I set my minimum requirements and I get my hands on my S85-002. We briefly inspect and undress common accessories.
In this entry, I document the changes made by BMW M to the S85 in attempts to improve its reliability. I cover which changes are worth it based on historical reliability and my experiences.
