I replaced my head bolts this week — one at a time. I only had one set of timing tools. I started with the driver side. Turned the engine to the 40 degree mark. Was able to insert the timing tools before removal. Replaced the bolts, set timing and installed the valve covers. I wish I had two sets of timing tools and locked both sides at the same time.
Then I moved on to the passenger side. When I opened the valve covers I wasn't able to insert back locking plate on the cams. Didn't know how my timing could be off from the factory. It was off by maybe 1mm and the plate wouldn't slide in. I turned the engine 360 degrees twice and stopped at 40 degree mark again. This time I was able to lock the cams, replaced bolts and set the timing. Put the engine together and started. No ticking or banging, but the engine is shaking at idle pretty badly and the check engine is flashing
I will have to re-do timing with two sets of tools. Any ideas what I did wrong in the process?
