Classic Mercedes advice.

Post by chevy4ever » Fri 12 Aug 2011, 08:17

Hi
I’m currently doing some work on a friend’s 1970 Mercedes 250CE, fuel injection model.
It has an annoying problem of surging badly at low speeds. You have to keep the revs up in order to get it going.
I have just taken it in to have the injectors serviced. But it did not cure the problem. :?

The other problem - It has the tendency of shaking its rear when driving above 40mph. actually feels like you driving in/thru ruts in the road.

Any advice or know where I can find a classic Mercedes mechanic would be greatly appreciated.

Regards
Ty

I know a very good mechanic in Queensburgh, reasonable as well.
That's how I roll. Down the hill 'cause the car won't start and the brakes don't work.

Howdy bud.

Sounds indicative of a vacuum leak to me, if you floor it, does it seem to be ok.

Vacuum leaks can be tested with a can of carb cleaner, sprayed around the pipes and gaskets, if you have a leak, it will be sucked in, and you will hear the additional liquid explode, ie engine noise will change, that means you have a leak.

As for the wobbly bits, sounds like rear diff mount(s) or control arm bushes. A good tug/pull/wabble the crap out of with a large something... will give you an indication.

Pity your so far away, I would of been able to help ya find the issue.

Hi Leonard
Thanx for the reply. The car pulls fine when it’s driven above 80kmph or when the revs are kept high. However I did notice this afternoon, the surging is almost gone when the car is cold, but gets bad when it’s at operating temp.
As for the vacuum, I coupled up the gauge on the port to the brakes; it took a long time to get up to pressure. Will try the carb cleaner, thanx for the tip.
The car still has the original oil bath filter, don’t know if I should keep it or change it to the cone type filter???
Will check the suspension out. Personally I think the old merc doesn’t like the big tyres (225/45 R17).

Regards
Ty
