This past summer I bought a 1486 that my cousins bought new in 77. Before I bought it they let a friend borrow it and he blew it up while using it. It sat for probably 5 or 6 years so I was able to buy it dirt cheap. The engine has never been touched or overhauled. The friend told me that it blew either water or oil out of the exhaust stack and he shut it down right away. So he says. I figured he blew the head gasket and possibly warped the head. I dropped the fluids and oil and water both looked clean. Next I pulled the head and sent it to a machine shop to have it worked over. They told me everything looked good, ground the intake valves a little, replaced the injector sleeves, and whatever else it needed. In the mean time I noticed that the radiator was plugged and calcified so I sent it to a shop to have it rebuilt. I ordered a new water pump and temp sending unit. I reused the old injectors and did not have them tested. I installed new copper washers and dust seals. I replaced the head gasket and set the intake valves to 0.020 and the exhaust valves to 0.025. It has the old cam shaft. The engine when running has a ticking noise and I can’t locate where it’s coming from. Rocker arms are getting oil and look to be running like they should. I notice either fuel or oil running out of the exhaust manifold. I’m thinking of replacing all of the injectors next. Also engine pours out white smoke. Any thoughts or suggestions? Thanks
