Is this true?

I went to see a 1990 300SE last night that my brother found for sale. 67,000 original owner and he had many receipts for service. Not all, but nearly. It's Charcoal/grey so it would avoid my black interior fears! Asking $8100, but neg.

Here's the weird part. A local dealership said if I wanted to have the car checked out there it was no problem. But, this car is not registered. It's been off the road 2 months. So, I needed someone to go to the car to see it. The MB dealership recommended a local shop they give their overflow work to. The fellow goes out and checks the car and other than a few very minor items he says, the one thing I need to be aware of is that normal maintenance on this engine includes removal of the valves and many times replacement every 40,000!!! He said thew valves are removed without removing the head so it's not a big deal.

I have NEVER heard of this. Is this true? I have a feeling not, because he also said if I looked into a 1990 300E, they last forever. Well, as far as I know, the 6 cyl in the 1990 300SE is the same one in the 1990 300E. So why would he say one car, engine wise, be better than the other? Now I'm questioning everthing he said about the car as far as it being in very good condition.

i bet if you ask him this question he would come back and say "because it's a Special Edition!". get another opinion...

How does one remove valves w/o removing the head?

Perhaps you have an exotic Ferrari engine in your car? Hence the frequent valve replacement?

This guy is trying you out to see what kind of mechanical prowess you possess. If he thinks you bought into his last "expert" advice, he looking forward to cash in on your ignorance!

Run like the wind from this guy!

Either G Benz is exactly correct, or he is talking about some other kind of valve. Unless there is an explainable understanding, I totally agree with G Benz' advice.

Have a great day,

Back in the days this car was delivered, there were some pretty common cases of fuel from the CIS injection system leaving deposits on the valve stems and poppets, which ultimately led to a crushed walnut shell treatment to clean it up. This was done with the head on. He may have meant a service to do something like this. Today's fuels have an additive to preclude the deposit problem altogether, and you can add some concentrated stuff with Techron (a Chevron product) to address the situation before it affects driveablility.

Also from around the vintage of this car, MB had some problems with valve seals. These can also be replaced without taking the head off. I don't think it is a 40,000 mile event you plan on though.

So, there may be an explanation along the lines that the guy isn't the most articulate individual in the business, but isn't a complete moron or a devious mechanic. But then again, he could be interested in the car too, as I think the price for one in great shape with such low miles is likely to be significantly higher than $8k in most instances.

Have the car towed to the MB dealer and have it checked out, with a compression test to find out if the car is really in that good a condition. 70,000 miles is hardly broken in, but if it has been sitting for a while it may need some work to bring it back into condition for daily use. If the car is decent sounds like a steal. Good luck, Jim

I don't know what state you live in, but most states will issue a 2 or 3 day "trip permit" to allow you to drive the car to the dealer..good luck

I have to agree with Jim...

My suspicion is this person saw the car and became interested in it himself, trying to steer you away from purchasing it. Get another evaluation from someone else, and go from there.

Good luck!
