Hi I had the same problem. Very noisy chain - the sound was caused because broken big chain guide. The fully opened hydraulic valve was the main reason for the failure. The pressure relief valve was in order. After installing new chain, big and small chain gide, hydraulic valve and arm, gaskets and oil the engine works like new. It is very usefull to have TIS. It takes me 1.5 days to finish the repair. Instead the speacial tool for the crankshaft nut you can use pneumatic nut tool. PS Before that the oil lamp worked strange. After starting the engine it turns OFF, after 1-2 sec lights ON for few second and turns off. After that there were no more problems with the oil lamp. Nikolay
