BMW Two-Valve Valve Guide 7mm with Valve Stem Seals different diameters

All BMW two-valve motors were fitted without valve shaft seals. This technique met the standard at the time. It was basically normal that combustion engines needed oil and overhaul intervals of 25,000 km for pistons, cylinders or cylinder heads were common.
Therefore, we have designed and manufactured valve guides with shaft seals for the BMW 2V R models. These reduce oil consumption and increase the wear limit. This means longer maturities and lower costs. We offer these valve guides for 7mm and 8mm valve shafts in the standard size 14,07mm and the oversizes 14,10mm, 14,12mm and 14,25mm.
You can purchase these valve guides from our shop or have them installed in our house as part of a cylinder head overhaul.
