Dimitri, Did you ever get this resolved? I think when we left off, you were going to replace the manual primer pump?

Now what?! Thanks! That will prove helpful. I have more troubleshooting to do on this car after ChowdahQ. In the meanwhile I adjusted the valves-they were way off! Strangely, all the exhaust valves had too much clearance and a couple of intakes were tight. I was under the impression that the exhaust valve clearances usually tighten with time? Anyway, the car drives a lot better. The idle is still a bit rough and it stumbles slightly in second gear while approaching 40mph. Something is still amiss. Compression test next.

No lint, dust, etc. I'd say 1-2 hours. Remove the lines (you have already done that. Remove the DV locks (screwdriver or torx) If you have the splined DVs, then you need the special socket. If the DVs are not too torqued, you sometimes can remove them with the splined lock with a wrench on the tab. This has never worked for me, and you really need the socket to get the right torque on reassembly. Remove the DV holders and keep in order, or I do one at a time. Use a pick to pull out the old copper seal. Inspect... find a culprit? (best to determine the weak cyl first.) put in a new copper seal, clean the DV holder, put on a new oring. use a new spring and replace DV holder Follow specs for tightening procedure and final torque. So is this DV repair pretty straighforward? How long of a job? Sent from my iPhone On Sep 5, 2012, at 12:57 PM, Dieselhead <126die...@gmail.com> wrote: Probably nothing to worry about. I remember freaking out about a similar situation, a wet hole, but it was ok when I put everything back together. If compression is good, then order DV seals (copper) and DV springs and DV orings. Rusty has em, but I can look up the part numbers if he can't find them. I ALWAYS order extra orings and seals. The copper seal is a one-time use, and generally if you pull a DV back out, the oring is cut from the threads too. A weak DV spring will act the same as a leaky DV seal. rough idle. I'd order 4 springs and 5 or 6 orings and copper seals. There is always one I want to do over. Follow the proper procedure for seating the DV seal and the proper torque. _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
