Shim Under the bucket Project is done...sigh sigh... My target lash is on the tight side/feel 0.27 on the Intake and tight side/feel 0.30 on the exhaust side. Here is the trick: I wanted all intake and exhaust lash to be exact the same but this is absolutely impossible to be done with shims sold off the shelf which offer 0.05mm increments only. In order to do the Perfect valve adjustement I needed custom cut shim with 0.01mm increments 2.16, 2,17, 2,18 etc.. After I measured all 24 valves and took very heavy notes, this helped to come up with quantity of 65 shim plates. Remember this is the Initial valve adjustment, later this will be a bit easier but no chance to skip the first nightmare... It's not an easy project, but if you want it to be done Properly, it's very time consuming. Concentration during the 50,000 times I took the bucket in and out there was allways a chance the shim to drop under the cam tray on top of cyl head and then no magnet will ever help during search...then cam tray removal is required.
The buckets are not even perfect from the manufacture. I had to balance them under 0.5grams.
In an additional improvement/work was also done to improve weight and oiling, which required a day of work at the machine shop.
After all my work with Shim Under it came out 3 grams lighter per bucket and with better oiling than the original Works DTM S14 back in the days.
The Shim Under in parts plus machine shop time is $2200 and that is without my labor... The Cam Tray modification I made plus the Shim Under project is about $3000 labor is not in this price. #s38b36 #EuroClassicMotors #bmws14 #bmw #s38b38 #e34m5 #m88 #e24m6
