I have been a 2 stroke buy until last year. Still learning these 4 tecs. While I have learned a lot over the past year. Can fix many things on them and install the engine now with my eyes closed, this is the first time I had to do the timing on one.
I installed an engine today but first time I had to put a cylinder head on. Last night I read and watched videos on how to do the timing. I had the number 3 cylinder at TDC and used locking tool on crank shaft. I had the cam shaft also set and used locking tool. Installed the gear wheel with both lines for 1503 even with body of head. Now the rocker arms were already installed at the time I did the timing. This was a full cylinder head just switching over to new short block.
I installed the engine. When I went to start it, it would not start. Sounded like a weak battery so I put another in. Same thing. Eventually it sounded like it was no longer going to start and I just heard a spinning sound (cam shaft). I took cylinder head top off and rocker arms were broken. Never really heard and breaking sound though.
Is this because timing was not don right? and if so what did I do wrong? I do have another good cylinder head. Would prefer to just use rocker arms from it since I did just buy the stretch bolts today for put it on and do not want to spend another $80 again for a days use. I will buy the rocker arm bolts but I want to figure out what I did wrong before I ruin another set then I am screwed.
