New valve seals tomorrow, couple of questions
My 1991 190E 2.6 is "going under the knife" tomorrow for new valve seals. Has been using 1qt per 5-600 miles and rough cold starting. Have already replaced the OVP and tested the idle control valve and they have not helped the cold start problem at all. Hoping that maybe it is caused by oil on the plugs and the new seals will remedy that.
1. While it is in the shop and the valve cover off (replacing seals ONLY unless guides are just shot to hell -- car has 130k) I'm wondering if there are any particular things I should have done.
2. Also, anything I want to make sure he does in replacing the seals -- I am assuming just OEM seals?
3. He will also change the oil. Should I continue with 10/40 or move thicker with 20/50 (Tennessee hot weather)?
4. How much to replace the shifter bushings while he has it?
5. How much to replace the front flex disc while he has it?
6. If you've had seals replaced -- how much $ and what was the book rate (# of hours)?
Thanks -- brookspw
