BTW, pointer for anyone following the Corksport valve cleaning guide in the future using that Harbor Freight gun. Even with the "Fine" grain walnut, it was clogging up the hopper and shutoff valve and it would spray a few walnut grains for a second and then clog up. I drilled out both the hopper...

Yep that's the plan, not gonna do all this and not change the oil too (also cleaned EGR, manifold, MAP and MAF, throttle body, and replaced PCV valve). Guess I'm just paranoid about getting anything in the combustion chamber.

Not sure I follow, what does doing an oil change have to do with getting B-12 in the cylinder if some leaks past the valves?

Followup on my previous post...so if one of the valves isn't completely closed and some of that B-12 chemtool cleaner leaks down in there, how bad is that? I'm using just a tablespoon or so at first, waiting a few minutes and see if it's still holding the liquid. But if I spill that much down...

That's what I needed, thank you!

That's a good idea. Might be a dumb question but does one 360 degree rotation of the crank equate to a full valve cycle? In other words if the valve is fully closed when the crank is at 12 o'clcock (or whatever arbitrary position), if I rotate it 360 degrees will that valve be fully closed again?

Thank you, but I know how to MOVE the valves by turning the crank, my question is how do I know that the valve is completely closed? It's kinda hard to see down there and judge if the valve is all the way closed (versus mostly closed). If I had someone to turn the crank while I watched the...

I'm doing this solo (unless anyone in the Durham NC area wants to hang out...), and without being able to watch the valves go up and down while someone else turns the crank it's really hard to tell if the valve is completely closed. Any pointers?

Yeah Yeah after digging around a bit more that's kind of what I was thinking too, thanks

is the movement/noise when I push/pull on the cv axle normal? Is there usually a little bit of play like that?

2008 Mazdaspeed 3 When backing out of the drive, when I hit the brake there is a small clunk coming from the wheel/hub area, then shift into 1st drive to the stopsign and hit the brake, same noise. The noise disappears completely once I'm on the road moving forward, no noises once I have braked...

I have not done that, honestly haven't done anything as far as "internals" go. Sounds like that may require actually removing the head? Would there be any way to determine if they need cleaning without cracking the whole thing open? I should also mention that this is a rebuilt 2008 engine...

Intermittent misfire on Cyl 1 only, every 100 to 500 miles or so. No drivability issues, pretty rough on cold starts but once it warms up runs like a clock. Both fuel trims surprisingly close to 0, never more than +/-5 on a recent 30 min drive/idle test. I replaced the plugs and all 4 ignition...
