I'm looking at a asv pt100 project. Machine starts and runs great, operates as it should. But... It has a engine tick. Perkins engine of course. No smoke, idles and throttles fine. Owner thinks may be a injector issue, but I'm not so sure. If I buy it, plan on pulling valve cover first and checking valves. Question is could a bad injector cause a constant tick?
NO.. not that I've seen anyway.. U CAN narrow it down to which cylinder it is by breaking the injectors loose 1@ a time..& retightening..
