I'm looking at doing a piston ring soak, and most instructions I've found suggest alternatingly pouring B12 into the cylinders and turning the engine by hand to work the grime free and get the solvent into the cracks.

However it looks like the crank wheel is very tight in the engine bay and it's not clear to me how to get a wrench in there to turn it, or if I could even move it more than a few degrees. I think I've also read that the accessories on this engine resist hand turning? Is this the case?

Has anyone done a ring soak on this motor, and what was involved?

Ok, what do you make of this:

  • Engine will grumble on startup when cold for about 10s, then purr just fine. Not close to stalling, but I can hear the misses.
  • p0300 and Mode06 confirms misfires across all cylinders (0,8,7,6 misfires on the first start, and 2,8,7,2 on the second)
  • No misfires seem to accumulate during warm idle.
  • Spark plugs ~new and do not look fouled. Square edges on both contacts.
  • Had the manifold walnut blasted.
  • I have extensive diagnostics logged from VersaTune during a cold start and could answer a lot if you tell me what I should report.
  • When warm and idling, short term fuel trim ~= -3.2% and LTFT ~= -4.6%.
  • HPFP is new and upgraded; also have a short intak

What do you make of this constellation of symptoms for my '10 MS3:

  • Intermittent p0300 multiple misfire code
  • Sometimes idles rough for ~10 seconds after starting, then smooths out. This is also inconsistent (seems worse on cold days, perhaps?)
  • Consumes lots of oil (needs refills between oil changes)
  • Walnut blasted the intake in an attempt to address the p0300 (it still appears)
  • On hard acceleration (like on a highway onramp), it'll have a serious "coughing fit", which feels like sudden and erratic dropouts in power. After lifting off the throttle, the bucking and lurching will continue and slowly subside over a minute or two. This also doesn't happen consistently; I've had some WOT

If I get lots of replies to a comment, then notifications will stop working. I will click on a notification, but it will not take me to the comment that generated the notification; it will take me to my own original top-level comment or post.

I believe this is because Reddit starts to hide subthreads when a thread gets very long, and the new comment is in a hidden subthread.

What I would expect is that clicking on a notification expands the subthread the new comment is in. Instead, I have to dig through hundreds or even thousands of comments looking for one that matched. (But it's lucky that I even understand what the problem is and what I have to do to fix it; I'd expect the typical use
