Hello Unintended acceleration, VERY afraid on cam shaft install. No OEM service tool to pull cams down before pulling the retaining caps. I get that. but starting at each end of cam and zipping with power tool.....OMG! Focus on the cam lobes that are depressing the valves and pull them with slow turns and multiple passes on all caps to spread the load and avoid possible cam shaft warp/non-true condition. I have my engines on stands and planned to add cams b/4 fitting to block.....but not possible due to head bolt location. Grrrr! Mr. P
Yes I understand your point, although it does look like I was senselessly just taking caps off I was focusing on lobes under load. And yes a lot of things can be frustrating when dealing with the s85. I’m no pro by any means but she sure is a beautiful thing! Thank you for your comment mr. p
@@Unintendedacceleration Clearly from watching some of your videos, you know what you are doing. I am not a critic and not my engine, only want your viewing public to be aware that these 'hollow" cams are very easy to distort for disassembly to assembly. I have tried to locate the BMW service tool, but it is hard to find and most likely very expensive. By taking MUCH time I will slowly pull the cams downs in a uniform pattern....much as the same you did based on your reply. When I pulled the cams, one cam on one engine was "sucked" to the head journal and "popped" up when I was removing.....my heart skipped a beat! Cheers! Mr. P PS: Your engine is IN and fully driving now? GREAT JOB!
@@Unintendedacceleration Yup, two stripped down to bolts, an extra "bare block" and the one in my M5 I'm a glutton for punishment....and now looking at Mercedes/AMG M156 engines.....when will it stop?
@@Unintendedacceleration Hello Unintended acceleration, I must have stopped watching video when I noticed power driver. So may ham-fisted "mechanics" out there that I cringed. I can see you only used the driver to pull bolts down, not caps. and then very careful with pull-down of cams/caps. WELL DONE and have the same plan for my engines (any engine). Cheers, Mr .P
Nice video
Thank you very much for the compliment👍

Thank you. Yes you are right, you must have multiple s85’s to rebuild?
