bad valvetrain noise

[F22A6X]

on monday i was driving going about 7o mph. its started to overheat with massive head noise and started stalling. I had it towed.

I checked valve lash. i had none. it was lifter to valve no clearance. i adj all valves per spec and fired it. doesnt idle well and valvetrain noise is bad.

im wondering why and what it is??

any ideas? fluids are fine.

Hmm if the lash was too tight and not letting the valves close, they never get a chance to transfer their heat to the head and have a good chance of being bent/burnt.

i was thinking that, but wanted other opinions. the oil light flickers also...

[F22A6X]

one thing. is the idle sometimes is ok. if I blip the gas it gets rough.

And there is still coolant in it? There's a chance when it overheated you warped the head.

[F22A6X]

still coolant... i should fire it and have the cap off... but still. no smoke out back. it sits at normal op temp.. just sounds like a diesel and has a interesting idle once revved.

probably beat the valve seat which makes the valve sit higher in the head and closes your valve lash.

also probably lose compression from the valve not seating.

what engine do you have f22 or h22.

[vh22accord]

If you have an h22 check the (#19) timing belt adjuster bolt and the(#23) AUTOMATIC ADJUSTER. some times thay fail and sound like valve noise.



If you have an f22 check the timing belt adjuster nut (#26) that it has not come loose
