Toyota 3.0 1mz-fe cam gears

Proper cam gear alignment for rear head

[dilldowschwagginz]

When reassembling the top end of a Toyota 1mzFe there is only one thing that held me up a bit... when installing the timing belt I kept noticing that it wasnt aligned properly. I took it off and reinstalled it several times but just couldn't figure out what causing the issue. I figured out early on that the problem was between the alignment of the two cam sprockets but they looked to be bolted on properly. Finally, after an hour or two, I figured out that for some reason the rearward sprocket had to be installed the opposite orientation of the front one. After unbolting it and flipping it over reinstalling the sprocket nearest the firewall (I believe that's bank 2 in a toyota) the timing belt lines up perfectly. I hope this helps someone who is facing the same problem. I have put around 20k on that motor since the head gasket job and it runs like a brand new one

I've had no luck timing this motor. For some reason it backfires on acceleration and as the lack of power and the running compression on that bank. I put the service bolt in the camshaft I align the cam lobes as described

This engine needs its oil change intervals cut in half... that goes double because this is one of the infamous sludge engines... I own two of them, over-maintaning this engine is the way to go if you want to keep it running for a long while
