Working on my 2000 LC with 350k miles. Decided to replace the timing belt along with pullies, cam seals, and crank seal. My question is; when installing the new timing belt I can align all 3 alignment indicators on crank but my belt arrows for the cam alignment are waaay off. I dont think any of my cams moved and I marked them before the seals. Is this normal for the belt arrown not to align?
