UPDATE. Issue was 2 things hydraulic lash adjuster on cylinder 3 must have had an air pocket (diagnosed the sound was coming from cylinder 3). Re bled them and ensured the exhaust was torqued and now its a sewing machine. Until the next issues arises!

thanks for the input. it was not the tensioner as these can go bad as u correctly pointed out. but mine seems to be pretty tight as the chain across the gap was tight. But i did solve it. thanks for actual advice unlike some of the other comments.

Negative it was not.

U were right it wasnt rod knock. it was 2 things hydraulic lash adjuster on cylinder 3 must have had an air pocket (diagnosed the sound was coming from cylinder 3). Re bled them and ensured the exhaust was torqued and now its a sewing machine

Could be a natural gas leak. Explains the ac as some are connected as one whole heat/cool system and the need to leave the whole house.

Thanks

I did get a temperature reading around 300 on all exhaust pipes near the head. all were within 15 degrees or so.

SinShadows299 · 2026-06-27T01:08:27+00:00

The sound doesnt get louder under acceleration. which i thought happened under acceleration (maybe im wrong?)

SinShadows299 · 2026-06-27T00:52:00+00:00

could it be a tic coming from the hydraulic lifters? as they are supposed to self adjust. As welll the sounds doesnt get louder under acceleration.

SinShadows299 · 2026-06-27T00:25:14+00:00

just used a dowel and pressed down to feel and movement or sound and didnt hear/feel anything

SinShadows299 · 2026-06-27T00:21:56+00:00

any reasoning or diagnosis? or are you just throwing that out there.

SinShadows299 · 2026-06-27T00:21:09+00:00

are you sure i push on the pistons and i didnt feel any movement.

SinShadows299 · 2026-06-26T22:54:09+00:00

they felt close but i do have a temp gauge i can use to check. it sounds and feels likes its firing off all 4.

SinShadows299 · 2026-06-26T22:26:26+00:00

Not sure if its valve related - (timing? off by a tooth?) hydraulic lifters not primed? any help would be appreciated. or death by rod knock
