then only thing that happens if you mess it up is it bends a pushrod. that's cheap to get replaced so not really a big deal to be honest.

heck my mower engine bent a pushrod before adjusting the valves was even necessary. it was at like 299hrs and the manual says adjust them at 300hrs.

you can't really mess up if you do it right. use the right feeler guage and use the above method. works every time.

original poster,
my engine was rattling and banging after replacing my head gaskets.
The set screws were backing out after tightening the keeper nut. The problem for me was setting these things at TDC. I was setting them at 0.4??
According to my friend and mechanic.............not working for my dealer anymore told me to set all 4 lashes at 0.6.
I did not do the TDC.........I did one side at a time and turned the motor until one valve was completely closed, then set the lash on the opposite valve. Then rotated the motor until the next valve was completely closed, then set the other lash. Did this 4 times around the motor.
Placed everything back and started the engine.
No more rattle..........no more noise..........runs like a kitten's purrrrrrrrrrrr.

Um, I think you may have got that backwards. You set the clearance on the valve that is closed, not the one that is open.

You are correct. Should have stated, i set the valve that was not depressed inward or closed.
Thank you my good man.

I was pretty sure that you meant it like I said it, but just got it posted backwards. After all, you said it runs great now, and it sure wouldn't if you had done it wrong.
