Hello I have a 1980 3tc Engine that is locked (Toyota Corolla 1.8) When I first purchased this engine the timing moved perfectly. I haven't even used it or turned it on at all. I put on the side draft Weber carburetors, transmission, headers, starter, and alternator. When I tried to put it on timing it was locked! (2 years later.. now) Things Ive tried: Take off transmission Take off headers Take off spark plugs Lubricated pistons Lubricated Valves I haven't taken off the intake and carb off. Any ideas as to why it is locked? Note: The engine has been rebuilt, but like I said earlier, the timing was moving and I know this is engine was good.
Thanks in advance.
