Help me identify if this is an exhaust leak...

[Juservic]

My panic is that I feel like this is in some ways a ticking time bomb... I don't know if the cam lobe is getting chewed up and sending metal everywhere and eating my rod bearings. I'd rather not get a visit from Uncle Rodney in the near future lol



I know that it is not a collapsed lifter, unless partially collapsed is a thing. I am not having any misfires or CELs.



Coming up on 213k. Secondary worry is that an AFM delete is not worth it at this point.



Doing my best to do oil changes at or before 5k. Now the last owners... I suspect did not do that.



40+ cold start, 30+ cruising, 15-20 hot idle. I don't have a manual gauge, but I know my oil pressure went up when I cut my VLOM gaskets when I had a lifter collapse. So that's a plus.

Thanks for the reply. Some good info here.

When my lifter collapsed, I checked my rockers and they did not seem to have much slop. I think checking them again would be a good idea.

Would a hydraulic lifter that doesn't pump up chew the cam or just cause drivetrain slop? Would the fix (other than new lifters) perhaps be a longer pushrod?

Hola amigo. El sistema AFM tiene la debilidad de que los taqués que actúan en el AFM se suelen agarrotar. Los vídeos que he visto parece que indican un agarrotamiento de un taque del A FM en el banco 2 en la zona del cilindro número 8. No arranques más el motor y desmonta la culata del banco 2, saca los taqués y comprueba sobre todo los largos que son los del AFM.
...y como decimos en España... suerte y al Toro

I has a slight lifter tic for a while until I added one bottle of Rislone (https://rislone.com/products/engine-treatment/) to my oil change. I know this is the band-aid approach, but it seemed to work. My understanding with the whole DOD issue is that the oil passages get clogged with dirt and sludge so why wouldn't an engine cleaner help? I have been using this for a while now and I'm satisfied so far.
