Hello everybody. I finally figured out why pics from this thread disappear. I used dropbox to host images, and dropbox pulled out all public folders, so people cant share pics on internet. I can not edit my old posts here to fix image links either.

I created backup of this thread on my home server and all pics are hosted on my server also. It's maybe not fastest, but pics should show up:

Keep your garage floor clean!

PS. Over time I'll backup suspension thread and my bmw posts - all of them are affected by disappearing pics.

Thanks Oleg, I'm about to do a full reseal and will no doubt refer to these often.

Oleg, a question for you on the valve guides. Why did you have to thread one end of the guide and insert a bolt, when you appear to have pressed it out from the other end? Also, where did you source the guides?

Here's factory recommended way - you need to machine down bronze till you see aluminum head.




Some machine shops machine step at valve guide top, so it will stop at correct distance. Problem with that - step will crack head and it's very hard to notice cause it's against head.

I used bolt as stop and press guide from chamber, it's not uncommon practice.




PS. As noted above most of pics in this thread will disappear sometime during Mar 2017
I have backup with pics here:
