Restoring a 120 C, complete off the body with a full engine rebuild. A trial start up with the engine etc.in the chassis. Went well, fired right up. Ran it 5 min. Broke my arm patting my self on the back. The next day I noted a small leak running down the side of the engine block from the third from the rear manifold stud. Took off the manifolds and the stud was leaking around the threads. The stud wobbled a little when almost completely in this prompted a Time Sert sleeve insert. Refilled the radiator, gasket sealed the threads and the leak is almost nothing but still there. Suggestions! thanks

I often see a post I think my be of help in the future. ( I'm restoring a 1099, 120). What is the best way to relink to that very post? The forum search at times has a lot to be desired. Thanks Bruce

I'm in the process of a 120 engine overhaul. I have 2 questions now and many more to follow, I'm sure. The first is that the valves, seats, stems and guides seem to me in remarkable good shape. After cleaning I get a good pop with my finger on the bottom of the guide as I pull the valve out without any oil on the stem. I will lap the valves. How critical should I be on this? The second question is that the timing gear, cam gear and timing chain also look great! There is a 1/2" slack in the timing chain. Is this a concern? Thanks Bruce
