Okay guys for those of you with 1992-1995 S-Class cars when your car goes into limp mode get it fixed, don't do what the previous owned of this car did and drive it with 6 of 12 cylinders working for any length of time. Tends to create a s***l*** of problems.
Because of this inattention to detail I believe I have a stuck oil ring on number 2 piston. Dave Walton was over a few weeks ago and didn't think it was injector nailing and we both agreed that the exhaust needs tightening up. Aside from pulling the motor and repairing it anybody have any suggestions on what chemical works the best for removing the built up carbon/scafootz on the ring(s) from properly working? I thought the GM product TOP engine cleaner would be my best bet but I wanted to check with the list first. For reference: http://www.greenmediaonline.com/uploads/shoptalk/0508_st.asp The procedural steps I would use would be to drain the oil and remove the oil filter, remove spark plugs and fill each cylinder with x amount of cleaner, hand crank it over a little and let it sit overnight. Drain the oil pan then remove the pan to see what is in there ie: particulate matter. Motor uses 1 qt of M1 15w50/100miles. Before I have valve stem seals done I thought I'd try this. This is a V12 gas motor. Runs strong with ALL kinds of power. Just burns/uses oil and has a noise in there. Will also look at replacing both EGR valves and cleaning the EGR tubes. And to make it more interesting my back was operated on to remove the cancer and am relearning how to walk. Sorry Kaleb not for sale. James Zavesky 1991 500SL 49kmi 1992 600SEL 137kmi
