I don’t have a catalytic converter anymore so no worries there. I will try a zinc additive and give it a few weeks.Just use the recommended amount and no more. It can shorten the service life of converters which is why the epa made the oil makers reduce the amount. At least that is the lore as I understand it. You can also get high zinc oils from Summit and Jegs. They are listed as racing oils or off road oil. But they are good for old road cars that need that lubrication. Stuff like old pushrod beetles and porsches as well as V8 classic stuff.
I already know it would since the noise only came after the reshim.Put the old shims back in see if It hushes up maybe?
5-30 is too thin

Yep, I'm currently running 5w30 full synthetic hi-miles Valvoline, and haven't noticed any issues except the 240 starts easier when the temps drop. Tha thin oil will be coming out in March or something. Hopefully no crackheads try to steal my nice oil.
Whip the VC off and double/triple check the clearances.
Yup, noise has been the same since day one of the re shim. I tried multiple sets of feeler gauges with the same results. Logged over a thousands miles, same noise, same clearances. It is not a clearance issue. I guess I'll just have to live with it and hope that the ZDDP makes it's way into the shims over time.Have you checked since you put it together and drove it?
Something, somehow, may have settled down and left a looser clearance somewhere. I dunno.
If it isn't an exhaust leak (and they are ridiculously similar to a valve tick), then it's got to be something slightly funky with one of the valves. Whip off the VC and eyeball everything, recheck the clearances with go/no-go feelers.
So are you agreeing or disagreeing?
The weight of my oil has absolutely nothing to do with this valvetrain noise. And even if it did, 5w-30 is perfectly fine in a redblock.
In the Volvo 240 Owner Manual(B21F Turbo, B23E, B23F) it shows both 0w30 and 5w30 for temps to -40f up to 86f, I think your oil will be fine. Like I said, I run 5w30 in the frigid months, never had an issue, truck on PR.
