Urgent -- M103 broken valve spring
 
Doing my head gasket and just spotted this luckily.

On a time and money constraint here -- Needs to be fixed by tomorrow.

Can I just replace the single broken spring and have the car drive-able?
Obviously if one has gone, the others might do in the future, but for both time-sake and fund limitations

What are my options here?

Best to investigate them all - to check their heights as specified in FSM.

However if you need to gamble then you need to gamble. Just replace the spring - though make sure there isn't additional damage you haven't detected yet. Ideally the springs should all be the same.

Just checked thoroughly the rest and they look ok.

Cannot get a spring anywhere including the dealers. Not a single spring anywhere in the west coast. Unbelievable.

I'll have to junkyard it to get me by...no other option.

Try a local machine shop that rebuilds the heads. They might have some. Ask your local Mercedes Benz independents and see if they have any in stock or old heads / engines laying around.

Haven't you torn down this engine before? Why does it seem like this engine is always under construction? :D How hard do you drive it? :eek:

I've got a 2.6L m103 sitting in my garage. The block/head are still intact. Let me know if you need anything

Just a perfectionist I guess!

Going to the junkyard tomorrow and grabbing the best spring I can find. Should be ok.

Thanks guys.
