For those who followed my tappet dilemma, the continuation is:
Head off and valve leakdown passed fine.
Possibility of a porous head, as I am loosing solvent from the 2 frt cylinder chambers. High ambient temp may be a cause, but is porosity an issue on these high port heads?
Ridge/space under the sleeves at about 3.5 thou...on spec.
Bores clean and pistons clean.
The broken pieces from the pushrods were sitting next to the hole were the tappet sits.

Camshaft. Do you guys have specs for cam lift? Nothing in my books/manuals. Would like to know if the cam is ok. Looking good from above LOL.

I can't find a way to attach pictures

Larry Young has a table showing some Triumph cam specs at Tilden Technologies

He lists a stock TR4 cam at 0.263 lift. Not positive but I think the TR3 cams were very close to that as well.

Photobucket is a good resource. Create an album, upload your stills, copy the img. info, paste the img info into your post here.Ta daa.
