Valve guides and or seals
How much should it cost to replace valve seals... and or guides on a 89 560 SEC. Have a serious oil consumption issue as mentioned before and I am told that I more than likely need at least valve seals and probably guides. How long will new valve seals last if that is all I replace? Help...

Not to start an argument here but I'd like to share a different experience. A couple of years ago I "only" did the seals on my 103 engine - not the Guides, when I replaced the Valve Cover Seal which was bad.
There was no smoking at all, just oil consumption & blow-by. Changing the seals dramatically improved (reduced) oil consumption. That and cleaning the tiny breather hole in the Valve Cover . My 2 cents Sorry but I don't know the answer to the Price question |

It just depends. There are some cases where valve seals can make a DRAMATIC difference. Probably the best example of this is the early 103 engines with defective seals from the factory. Replacing them with the updated ones corrected the oil usage problem entirely. With other engines you just never know.
You should start by determining that you don't have a cylinder related problem. Do this by doing a compression check or better yet, a cylinder leakdown test. If the rings are holding compression good, then give the seals a try. Good luck, |

I was using some oil in my 88 560sl
This past winter I replaced valve seals they were very brittle It is amazing how much it helped I haven't added oil at all and I went 1,500 this year. Seals do make a difference in a 17year old car with 79,000 miles The guides had some play in them I think .004 as I remember on some???? But I felt what do I have to loose I tryed the seals and works so far Cheap fix

_________________________________________________________________ You should be able to do the guides and seals at a good indie shop for somewhere in the $500 to $700 range.

Thanks and ???
My thanks to everyone who has replied to this post. I purchased the 560 from a guy on eBay 2 weeks ago. He lived in Boston and seemed to be honest over the phone. I bought the car for $8500 with 137000 miles. I flew to Boston and drove the car back to Dallas. The seller assured me that there would be no problem with the 1800 mile trip. Long story short I had to buy a set of tires in New York on a Saturday afternoon ( 2 were separated and 2 out of round). The car drove well but I quickly noticed the oil consumption, 1 qt every 300 miles!!!!!!!!!!!! I am trying to settle the final feedback on the purchase and the seller denies knowing about the oil problem, but says he is willing to make restitution. But how much?
Lastly can someone suggest a reputable independant shop to effect any required repairs in the Dallas, Ft. Worth market. Again Many thanks for all the replys. Steve Katz repairsetc@ntin.net |

According to the Kelley Blue Book, you paid about double of what the car is worth. They show a 89 560SEC with 137,000 miles and the basic stuff going for about $4300. I did a cut-n-paste on what was returned below.
Go to KBB.COM and check it out yourself. I doubt the seller didn't know the car was drinking a qt. every 300 miles. If the "low on oil" light works he had to notice it unless he was oblivious to this sort of thing, in which case he may have run the engine low on oil. Good luck with this car. You may need it.
