Friend's 2009 c63 went into the shop last week after ingesting 3 full reservoir tanks of coolant. Turns out it was the head bolt problem.
After about a week of repair, MB dealer says that they have a timing issue and have to put on the OEM pulleys. Right now, my friend has aftermarket pulleys and a ecu tune car is at about 39,000 miles. Until they fix the timing issues, they wont release the car. Pulleys shouldn't affect timing, right?????


I have a 2010 e63 at 36k miles, now i'm worried.......

What do you mean, aftermarket pulleys?
Is it safe to say no warranty because of the tune?

dsl

not even sure there is a tune, but he has the pulleys for sure. From my experience pulleys dont mess with the timing, right?

Critter

again what pulleys, the crankshaft? idler pulleys? or ??.
Timing is internal on these engines and chain driven under the valve covers so if there is a timing issue it would seem that the tech did not put the engine together properly. IMO

The crank pulley has a specific 40degree mark that must be lined up to get the cams and timing all aligned or you will never get the cams back in.

so is this yet another case of BS from MB svc to avoid incurring warranty hours?

dsl, Why doesn't friend blog? Post pictures of removed bolts. Send me the bolts for "who dunnit." We are getting nowhere at the rate we are going.

thanks motoman

Critter

Just what non OEM crank pulley is available for an E63, is it smaller in diameter?

OP - Am I reading between the lines correctly that this IS a warranty repair?

bhamg

motoman - I will PM you shortly...may have good news next week.

got latest info..

so he let evosport use his car to prototype their pulleys. in doing so, they just jammed the pulley on and cranked the bolt on to tighten the crank pulley which damaged the woodruff key.

mb fixed the headbolt under warranty stating that they have been seeing this problem and aware of it, but charged another $5000 + parts to change out the woodruff key. supposedly, they have to take the engine out..... my friend was tired of it all so he just said F it. and let MB dealer fix it.. still at the dealership. will keep you all posted.

sorry no pix. this is in the LA area.

So who is getting stuck with the $5k bill?

dsl

my friend is. supposedly that's the cost to fix the woodruff key. which supposedly entails removing the engine from the car to do...

repairs for headbolt failure were covered under warranty

LuisC55AMG

At least those will be covered by the warranty. Please keep updated. Tell ur friend GL with the repair.

CoolBDPhenom03

If Evosport damaged the key, shouldn't they cover all or part of the repair? Or did he sign some kind of release of liability?

bhamg

Thanks for the update dsl.

Sincity

Wasn't the latest story that they were having financial problems? Sucks for your friend to be stuck with a $5k bill

_timothy

then again, it is evosport. no way youll get a dime out of them. this is why their website is slow, theyre too busy breaking cars.

dsl

i heard they went out of business...

Merc63

Could have always drilled some new key ways on the pulley and the crank like weistec does for the blower pulley.
