So what started as a home garage passion is turning into serious mechanics for me. I am now repairing small problems on BMWs and already have a retinue of believers. It takes a little madness to do this but I have the comfort in the fact that if I mess up a car I can take it to Bavaria:D:D
So an acquaintance had a smoking E46. I diagnosed it as having worn valve seals. He challenged me to try replace them. I had never tried anything like this. Looked at the repair manuals and said what the heck!!
One week later the valve seals are replaced and we are now starting to put it back together. To replace valve seals most mechanics will pull out the cylinder head. Not yours truly:)
Remover the cylinder cover
Removed the camshaft and its furniture
Started with cylinder one and kept the valves loaded so they don’t fall in, pushed the spring in (three fat chaps) removed the spring, seal, put in new seal. Pressed the spring in (three fatter chaps), locked valve in.
The job takes a day but getting a special tool to enable me do it all in one Sunday since I still have my office job to keep…
Now Ill start retiming the valve train. Wish me luck!

There you see the two vanos sprockets (what japan calls VVTI) and the camshaft, exhaust side. Its rockers arranged by position
Yap, left to idle the car begins to smoke big time after 10 or so minutes.
Failure and mistakes are the only sure paths to absolute knowledge. I don’t fear to fail or to get it wrong. I have the tools, the medulla and the strength to go back at it until its working 100%. I am sure I will do this just as well as a trained mechanic. I have the benefit of BMWs workshop manual.

ION if you take your German machine to the guys right opposite Yaya please lube yourself.
Those guys do not know their shit.
@ochithunder awesome work my jalopy is in dire need for valve seals replacement. Quick question how do prevent the valves from falling into the chamber?
What about grinding the valves so they can have a perfect seal for the chamber?
