RR tire was leaking down suddenly. Took 3 attempts to finally identify the valve core as the culprit. Holding just fine now. Lesson learned don’t skimp on soap to water ratio for the spray bottle.

Followed troubleshooting TM for low oil pressure indication. Validated with a mechanical gauge for extra assurance before ordering a new sensor. Plenty of pressure both cold and hot. https://youtube.com/shorts/aWPWo8CzNfY?si=NYUvthszZVFVgr0r

1/4” NPT confirmed Plenty of oil pressure cold and hot. Will be replacing sensor. https://youtube.com/shorts/aWPWo8CzNfY?si=NYUvthszZVFVgr0r

I’m going to be testing my oil pressure with a mechanical gauge soon. Does anybody know offhand the thread pitch of the sensor? I was looking to put a tea fitting in.

washer reservoir and pump.

New LF floor mat. More work than I anticipated.

4L80E dip stick grommet. Super easy.

There was an occasional mystery noise I had not been able to locate. Just happened to notice when doing other work on the vehicle

Harmonic balancer failure. Caught it in time to avoid block damage from the ring rubbing on timing chain cover. WOW.

Finished installation of all the body mounts. I was able to reuse all the hardware without having to use longer bolts. 90ft/lbs seems a tad excessive on the mounts IMO. Gather the factory spec wants metal contact between the center sleeve and the lower bushing plate.

Figured I’d upgrade to the REV style mounts. Thanks for the tip on balancer replacement that’s a relief

Body mounts were just slightly compressed 😂 LT valve cover, intake manifold and plenum are back in. Front two mounts are in. Need to address the next (4). Found the balancer has failed - outer ring came off and is contacting the oil pan. Looks like the cooling stack has to come out yet again...

valve cover off now. Typical gasket over tightened and warped cover

I have the LT plenum and #1,3,5 injector lines off. Stuck on #7 as I can’t seem to get the crowfoot & wrench on from a LT attack position. Really would like to avoid having to remove the RT plenum and even numbered lines just to get #7 off.

Old thread I know. That said, just saw this bleed 🩸 fitting off the CV on my 1151. I don’t recall seeing one on my 998 before.

I’m looking 👀 forward to seeing the old upper mounts out for inspection. From what I can tell they are all significantly compressed

Ordering replacement body mounts now. Per TM 9-2320-387-24P-C05 My 1151A1 is sub 3K serial number however it looks like the mounts can be updated to the new style. Ordering a few 5340-01-568-4874 "AMG STARTED USING A NEWER VERSION OF THE MATERIAL IN 2019 TO RESOLVE THE ISSUE WITH THE CRACKING...

Body mounts are definitely compressed. Followed advice and raised the body a tad. This plenum is definitely taller as well

Which mfg/type of grey? Presume high temp rigid….
