What alloy are your pistons made out of?sn95 hanger, so the bigger 3/8 feed but still a dinky 1/4" return. the rest of the system is all -8, so if i ever get the itch i can swap in a different tank with a bigger (or multiple) pump.
just a bit. exhaust is on now, just clamped up ran out of mig gas and cant find my flux core tips so that will wait till tomorrow at least.
it is making a hell of a mechanical clack though, i know one rocker trunnion is looser side-to-side than the others, just hoping it something like that and not a rod bearing on a brand new motor (oil pressure is 50psi at idle and never drops, which amazes me since all my 302's have been like 25 or so). it's been making this noise since the first start, way more noticeable now with mufflers.
So the noise shouldn’t be from them during warm up. Hum.....2618
The noise is most noticible during a cold start and during idle. When the pistons are cold.So the noise shouldn’t be from them during warm up. Hum.....
not yet, dont even have a dipstick in it yet :eeks: still in the package, almost forgot about it. its only got about 30-40 minutes of actual runtime since i dont want to piss off the neighbors too much (and the head "hoa" people live right next door).Have you cut the oil filter open yet?
when i first noticed it, it was after warmup. its started closer and closer to startup ever since, and yesterday it was obnoxious as soon as it lit. oil pressure is still awesome though, which makes me think its valvetrain more than bottom end. or at least, i hope.The noise is most noticible during a cold start and during idle.

Anything isolated to one cylinder would be cause for concern. I would agree that A slapping clatter would be more of a valve train noise than the Pistons rocking. The valve lash is freakin noisy, but consistent , and the Pistons make that repetitive rocking noise. Anything else banging around in there would be cause for investigation.not yet, dont even have a dipstick in it yet :eeks: still in the package, almost forgot about it. its only got about 30-40 minutes of actual runtime since i dont want to piss off the neighbors too much (and the head "hoa" people live right next door).

this is uncharted territory for me, never had a solid roller before, so dont know what that sounds like first hand (though this noise is defintly only coming from just one cylinder). also never had rod knock or piston slap, so again dont rightly know what those sound like.
My mistake, i was getting those confused with 4032 forged pistons. I got it backwards.The noise is most noticible during a cold start and during idle. When the pistons are cold.
How many transmissions have you gone through (ie taken apart and reassembled)? I really want to find a core and take it apart, but after watching a few videos, I can't convince myself to do it. Seeing your pics above made my palms get sweaty.The sonnax stuff is for sure super expensive, their upgraded direct setup is around $600, and the forward is another couple hundred. But it seems that's what you need for 1k+ hp (well that and maybe an upgraded planetary if someone can be persuaded to make them). I'm nowhere near that, so I just grabbed another used stock loaded drum off ebay. If I didn't already have the friction kit, there are modifications to add 1-2 clutches to the factory drums. While I knew the clutch pack was probably toast, I didn't think it would take the non-consumable parts with it.
Also have an oil leak to figure out (hoping it's just a valve cover or needs more etc on the rear China wall and not a rear main issue). Will also need to rebuild my dropped trans mount (seems my little welder doesn't have enough ass for 1/8" hotrolled in actual mig mode) as well as remake an exhaust hanger (mig failure again).
i tore down a t5 before i found out mine was some bastard child and couldnt find a new input shaft, and also rebuilt a tko. this is my first auto, but as far as the drivetrain goes its amazingly simple. the only pita parts are some snap rings that need what the hold in, pressed down so you can get the rings out.How many transmissions have you gone through (ie taken apart and reassembled)?
