Just sealed up my engine and noticed that the front cover crank seal has a slightly bigger gap on the top of the crank shaft than the bottom!
it's a very slight difference and when the front cover was installed it was flushed with the block!
should I break a few bolts on the oil pan and re set the front cover so the gap is as equal as possible?

Thats not an LY6 front cover. LY6 cover had the bulge for the phaser….irrelevant info there for this situation, but I figured I’d throw it out there. The ONLY way your going to properly do this and it not leak oil from that seal, is with either a front seal/cover install tool, OR do what I always do on every LS build and just use the damper (and I’ve got the fancy SacCity tools in my tool box). So you want to loosen the cover bolts a tad…just until the cover will move a tad in all directions, and install the damper. The damper will center the cover for you. It’s better to do this BEFORE you install the pan, so the cover has the freedom to move anywhere needed, but you might still be ok here. Once the damper is set, move the cover with light pressure around to ensure that the seal is centered. Then re torque the front cover bolts. Tighten the bottom two bolts last, as they pull DOWN on the cover and will mess up seal alignment here. You’ll want to re-do the dab of RTV on those pan front corners…which might require taking the pan back off. Sucks, but it’s WAAAAY easier to do on the stand, than in in car. Make sure your oil pan is properly aligned out back while your at it. Alignment is critical back there.

Cheers, I do have an alignment tool and yes it's not an ly6 cover as it's had the vvt delete but it is a ly6 engine! I'll pull the pan and re do it.
thanks for the reply!!
