Loud Valves/Injectors After Valve Adjustment and Oil Change?
#11
Do you follow a specific DIY when you do your valve adjustments? I've never done one myself before, but I definitely don't want to pay the $300 the Honda quotes for that job.

I follow this:

I bought the valve adjustment tool linked in the second thread (haven't used it yet, you don't necessarily need it), and flat feeler gauges that I bent myself.
30 min start to finish to just check valve clearance when you are familiar with the process. Longer your first time, but certainly a doable home project with moderate mechanical aptitude.

This is what I use as a reference and I also have the service manual.

It's not that hard, just take your time and triple check your work. The hardest part was puting the cover back on. It will be a lot faster the next time I do it.

It's super simple, I disco the battery, make sure car is cold, I like to do it 1st thing in the morning. Remove valve cover turn engine at the crank so the cam lobes are away from the valves, slide in your feeler gauge (get the ones that have a kink as it's easier to get em in), loosen the lock nut then adjust the adjustment screw until there's a drag on the feeler gauge when you slide it under the adjustment fastener and top of the valve stem then tighten the locknut to 14ft lbs. I adjust both intake and exhaust to .01"
It's my experience that the valves tend to tighten, so I leave them on the loose end of the range.
Just make sure you turn the crank so that each cam lobe is away from the valves on each cylinder.
For reference, all valve cover bolts are 10mm and the hex bolts that cover the coil packs are 5mm all bolts are tightened to 9ft lbs. Also it's a lot easier to remove the valve cover if you unbolt the two tdc sensors, and the bracket that props up the wire harness to the firewall. Don't lose those o rings on the sensors.
I also like to replace the spark plug seals and valve cover gasket.

What ever happened to reading comprehension? Or if u r 2 lazy 2 read the post, then don't make yourself look stoopit by posting things that don't jive with the post.
The guy didn't do the valve adjust himself. He brought it to a shop. Yes, he knows to go back to the shop, he just wanted to hear from us if his new sound is normal.
My answer, yes, an engine could be noisier after a valve adjust, if the valves were tight beforehand (ie; noise now is normal, before it was abnormally quiet). Ask the tech what the valve clearances were before he adjusted. That will tell us if they were tight enough to now make more (normal) noise.

The chain is not driven off the oil pump, it is driven off the crank. The oil pump chain drives nothing.

His explanation was that since the chain is driven off of the oil pump and the viscosity of the oil might be slightly different, the chain could be spinning differently
