I was recently doing some work on my 3VZ-E and noticed that the one of the bolts on the No. 1 journal on the right side had been stripped out. So, I installed a helicoil, bolted down the journal and thought all was okay.
The motor had some problems starting and, when I went back in to determine the problem, I noticed the right camshaft was virtually locked up. I pulled it out and the No. 1 journal was roughed up pretty bad. The camshaft was scored badly as was the journal right next to the front camshaft seal.
I have no idea what I did wrong.
My question is this. Is there a way to repair this situation? Can the camshaft be taken down on a lathe and then some sort of two-piece sleeve be placed in the journal? I would hope so. Otherwise, I suppose I would need a new camshaft and a new head.
TIA for any help.
