Carbon clean take 2. Weather was better today. FYI if you have a nut/stud on the upper edge mounting points on your manifold you will have to take off the HPFP line. The stud extends out an inch or so and there is not enough clearance on the driver side. Some stuff you may want: magnet thingy to hold/pick up screws. Hard to balance the T30 on the tip of the ratchet and lower it into position at a downward angle without it falling off and underneath the manifold. Short 17mm wrench for the lower portion of the HPFP line. Not much room to tighten, hopefully mine is tight enough? Small vacuum/blower for all the little carbon bits. Almost impossible to fish out with picks. I was using the brake cleaner to blast it out and then wipe off. Only had time to take pics of cylinder 1 and 2 post cleaning, was running out of time. 3 and 4 were not as clean as I would have liked.
