Michael Warfield :

Yes it could be.

Michael Warfield :
Michael Warfield :

Did you reuse the timing chain tensioner?


 

Customer:

i did fix d car my self

Customer:

but am beggennin to doubt d mehanic

Michael Warfield :

If the tensioner was not reset, it will destroy the cam


 

Customer:

i didnt fix it my self

Customer:

what about the vibe

Michael Warfield :

The timing chain tensioner must be reset, if it wasnt, it will cause too much tension on the camshaft and break it


 

Michael Warfield :

vibe?


 

Customer:

the mechanic ssaid d camshaft is only could dat be tru or i should look out for more thing

Customer:

gone

Customer:

the timing chain didnt loose out wen d car stops wrking

Michael Warfield :

Well, if it broke while you were driving, the valves may have gotten bent.

Customer:

could i be lucky on the valves , cause he said i was lucky , that d valves are still ok

Michael Warfield :

You could have gotten lucky but there is no way to tell unless he did a cylinder leak down test.


 

Michael Warfield :

Your mechanic might have done this though.


 

Customer:

as a customer to him how would i have know if it was his fault , cause he just change d timming chain, and after 3rd day d camshaft got broken

Michael Warfield :

Ask him the steps how he installed the tensioner. If he doesnt tell you that he reset it, you know he didnt and thats what damaged the camshaft.


 

Customer:

cause he didnt want to accept laibility

Michael Warfield :

You can then show him this text.


 

Customer:

ok

Michael Warfield :

A lot of unexperienced mercedes mechanics do the same thing to this engine unfortunately.

Customer:

what more could cause damage to camshafts

Michael Warfield :

what exactly broke with the camshaft?

Customer:

he said just d camshaft

Customer:

let mi ask u dis good question

Customer:

probably last question

Michael Warfield :

Well, the only thing that would cause that would be improper replacement of the chain by not resetting the tensioner.


 

Michael Warfield :

ok


 

Customer:

what sign do i get if the chain wasnt fit very well

Customer:

or tensioner

Customer:

tensiorner reset propaly

Michael Warfield :

You would have worn the chain guiderails prematurely. If the chain wasnt timed right, the engine would have ran very poorly from the start.

Michael Warfield :
Customer:

ok

Customer:

thanks

Michael Warfield :

Your welcome and good luck. Make sure the mechanic doesnt do the same thing to your new camshaft.


 

Customer:

ok

Customer:

i hope so

Michael Warfield :

Dont forget to rate your experience.


 

Customer:

sure
