Excessive Valve Clearance Cause Noise (1 Viewer)

[landtoy80]

Can out of spec valve clearance cause noise? I am getting tapping/groaning noise from the valve cover on my Camry. As the 96 V6 Camry and 80 uses the same valve setup it shouldn't make a difference either way.
To keep it 80 Tech, if my 80 has excessive valve clearance, will it make a tapping noise? On the Camry the noise is only between 1500 and 2500 rpms.
I removed the valve cover and and only one exhaust valve is out of spec .002". .016" vs .010 to .014" for in spec.

I need to check the valves on the 80, its been a while.

If I play the swapping of the valve shims, can I swap out Camry 1MZ-fe shims for 80 1FZ-fe shims and vise versa? Assuming that they are the same size shims.

I could be mistaken, so this post will essentially be meaningless to you...

but I believe I discovered the 1FZ has its own unique set of overpriced shims.

Isn't that the case with most manufacturers? I remember a long time ago looking for shims thinking I could get some kind of generic "kit", but was annoyed to discover it was quite engine specific.

Then again, now that I think about it, that was a Toyota engine as well.

IIRC the 1FZ has hydraulic lifters, so clearance shouldn't be an issue with that engine.

If it was a 3FE, adjust it as best you can and lift with what's left. Those things always sound like sewing machines.

The 1FZ does NOT have hydraulic lifters.

Got my learning in for the day


Adjust that clearance!

They use a Shim on bucket design like all there other DOHC engines.
