We're good! No offense taken. We'll get through the translation issues. Thank you for telling us about the auction. That's the kind of thing we usually know about right from the start. I had a suspicion that might be the case- that you bought it in this condition. So, maybe not such an easy fix afterall, but we'll definitely lend you a hand.
Hopefully, you just need to replace a shim, but that is awfully tight, which doesn't sound good. Instructions for removing the camshaft, replacing shims, setting the timing, etc. is all in this link. When I first needed to do this I could not find any mention, text or video, on this process so I had to jump in. That's when I learned about the decompressors. By now there may be other sources you can find online, but not sure. I'm up for the 40K mile service and will probably do that sometime later this year. I'll probably create a more thorough version at that time. For now, you seem pretty handy and this and the manual should give you all the information you need, including the necessary tools. Start at the beginning and read through the entire post......
Part 1 This includes valve clearance check and shim replacement. Also air, fuel, spark plug and coolant replacement, and bleeding the clutch. This is a work in progress, so edits and further information to come... Get the service manual here...
