- Scott, Try an easy-out for the stud. Soak well with "liquid Wrench" first. Should takecare of this situation. As for carbon on top of pistons and crud down side of cylinder. Rotate engine by hand to

- had Yup, that worked most of the time. In this case thought it broke the threaded portion off. A "stud remover" then broke the rest of the stud off flush with the head. Drilling was my only resort.

- NO! NO! NO! Never turn over a TR engine with the head off or without special factory or home made fixtures to hold the wet liners in place. If the engine is tight (and it will be) the liners will mov

- Nope, you're not being paranoid - you really don't want to break the figure eight seal at the bottom of the liners. What you need to do if you're going to rotate the engine is to use some washers (an

- Scott, Hmm, worrying about liners moving with the head off? This is a worry if the engine is brand new or just rebuilt, but if it's an original engine with 30+ years on it and normal abuse those line

- The early TR engines are based on a farm tractor engine. Wet liners are not uncommon in this application. What makes a "wet liner" engine different from, say your TR6 mill is this. The casting in you

- I'm guessing that you cant go cleaning off the pistons while they are still installed? Getting some of that carbon down on the sides for the piston rings to deal with would not be good I'm guessing.
