Intro - If you have some experience working on your TW, just use the TW200 main manual. It provides enough detail you should be fine. If you have little or no experience you may want more detail, thus the purpose of this guide. The guide may look a little daunting, but none of this work is difficult. Like eating an elephant you just need to approach it one step at a time. I would encourage you to read through the instructions and maybe watch the videos to get an overview, then dive in. Read one set of instructions, then do that particular task and move on to the next and repeat.
If you're concerned you won't be able to remember where everything goes take pictures with your digital camera, or better yet get an accomplice to do so.
I've done the base gasket twice, now. The second time was because I didn't verify I had the correct base gasket the first time. Yeah, I know, kind of dumb of me. The parts person assured me the newer part number would supersede the older one. It didn't. You can avoid my mistake by simply ordering parts for a 2010 TW.
The first time I did the guide I took pictures and wrote up the description. I described how to retain cam timing. In revising the guide I filmed video, and demonstrated how to restore cam timing. So this aspect of the video description and written instructions is different.
After viewing the videos it has caused me some anguish to recognize that I made some mistakes. Each time I saw a mistake, I went to the written guide and revised it to reflect the better way. So, you'll see some differences between the video and written instructions. You can choose which way to go with cam timing, otherwise I would follow the written guide. I just included the video because it's helpful for some people to see it done. I wish I could do it again to clean up the videos, but it's impractical for me to do so, and I think it's beneficial for you to see the mistakes I made so you can avoid them. So, recognize the videos aren't completely accurate, the written guide is much better.
