Reinstalling the camshafts requires using NEW copper crush washers (lots of them, as I recall), and they're not cheap, as well as o-rings,




(IMG:style_emoticons/oldemoticons/unsure.gif) Huh? You sure about that? I adjusted mine at 16K and didn't replace any copper washers or o-rings.

I've been into mine twice and haven't replaced any either..

I am sure. Factory manual (for '98) at page 8-30 says to use new copper crush washers ("sealing washers") when reinstalling the cams, and I do it (8 per head are used). Suggests to me they want the crush factor in the torque mix, and that's out of the mix when you reuse a crushed washer (arguably resulting in over-torquing and possible thread stripping). I'm no engineer, so I just do what they say. Clymer Manual and Haynes Manual say the same thing.

NOTE: While the sentence in the Factory Manual is poorly written ("Install new sealing washers and flange bolts."), my research determined that NEW "flange bolts" were not necessary, a fact I believe is confirmed in the Haynes Manual.

NOTE: Above re: replacing sealing washers only applies if you've removed cams to adjust valves (or for any other reason).

Good. Glad that is sorted out. Makes it more attractive to get in there now, knowing it may not be quite so expensive an ordeal.

You are correct. 4th Gen doesn't use any washers on the cam holders. We now return you to your regularly scheduled valve adjustment thread, already in progress.

Yeah, them new-fangled eelektronic fuel squirted VFRs are just a pain to fiddle with. Really took the "shade tree" away from the home mechanics and their wallets too! (IMG:style_emoticons/oldemoticons/goofy.gif)
