Check 1st your tire size is correct to the label on the door pillar,
next check the tag on the differential against the Vin, or verify by spinning vs the ratio, someone may have swapped it..

lut a couple of quick checks...

 

Hey, thanks for the suggestions. I'll check it out tomorrow.

 

I had that problem. Also, I thought the car was geared a bit too low, wanted to add a bit of overdrive to the whole thing so I go with larger rear tires than specified. 205/75R14 is my normal size. Around 25 1/4 to 25 1/2 in. dia. I think recommended size is about 23 3/4 (195/65R14). Did the trick on both counts.

Hasn't been a problem in terms of geometry that I know of. Has a nifty hot rod look to it. :angel:

 

the few ways to correct speedo: recalibrate, regear speedo sensor, increase/decrease tire height (second number on tire size)

 

The tire size seems correct. Mine are 195/65R14 88H M&S. Car tag recommends 195/65R14 89Q M&S, so they don't seem that far off. Perhaps the sensor or needs recalibration.

 

I would use the unichip to recalibrate your Speedo & tune the car at the same time

 

Car is in the shop again so I will ask them to check on recalibrate while its in there. They just replaced the timing belt two weeks ago and it has slipped off again. WTF? They have it apart and are examining it to see what's up. I wish I could drive it for more than two days at a time!

 

Whoa, wait a minute... the TIMING belt 'slipped off'? Again??? as in it's done that before? I think you're talking about the fan/alternator/power steering belt. If the timing belt (the cogged belt under the front cover) really DID come off, it did more damage than what you think. Bent/broken valves, broken rocker arms, dinged piston tops.

 

Well, yes, it jumped a tooth a few weeks ago resulting in a bent valve in #1 but they fixed it to the tune of many thousands of dollars, but yes, I think it did jump a tooth again last week as I was driving along. They have it disassembled again and are inspecting it but wouldn't give me much info over the phone. I'm guessing they screwed up the repair and are frantically replacing everything before revealing this to me. Who knows?

 

Probably. ...that's a shame... newly installed timg belts don't just "jump" time, bend/break stuff unless incorrectly, incompetently installed,..

I'd be insisting on a complete new headw/valvetrain..maybe an engine if the valves kissed the pistons,, and a complete refund...find another repair shop ..one with a bunch of polished well-cared-for E-30's in the parking lot is a good sign..

at the very least the shop should be up-front honest, and show you, make you aware of the damage..

This precisely^

They screwed up something big-time. Sounds like the timing belt tensioner wasn't preset properly. :tsk:

 

Yes, I believe you are both right. They are the "go to" German repair shop in our area with a sterling reputation, so I don't expect any problems with them blaming me for anything. They've been very helpful so far in restoration, giving me some good price reductions and also some freebees on stuff they overlooked and didn't charge me for reattaching my front air dam properly. They have a beautiful one owner 190SL waiting for parts from Germany, so they don't fool around with sketchy parts. I'm holding my breath for tomorrow to see if they can diagnose the problem. No worries - I have all my ex-husbands ready to go over there and scream their heads off, so there's that.....
