- SLK 280
I am looking for a specialist in the Northwest preferably, who has experience in rebuilding or part rebuilding the 272 engine.
My problem I think is related to the premature balance shaft chain/gear wear (engine light on) which is well documented, law case in USA etc.
My car is an SLK 280 registered in 2007, owned from new and has only 65k miles. I really thought that the purpose of chain drive over belts was improved reliability and longevity......not the case!
It currently still runs well and the serial number of the engine is later than the 468993 stated in other reports which indicates it has the modified balance shaft/gear.
The pickup magnets were also replaced last year but the problem has returned.
I would like to get the engine repaired but have seen the complexity of the work on U tube and I am a little nervous about having the work done by some one as a first time. I also wonder how reliable the replacement parts are likely to be.
There must be a cause for this excessive premature wear. I have seen reference to only using Mobile 1 0w/40 fully synthetic oil and fleece oil filters. I do know that my Mercedes dealer used Castrol products from new, no idea if this is really a cause.
I have been in touch with a specialist engine builder who informs me that Mercedes do not make over sized pistons for this engine variant so cannot do a fully re-conditioned build if it needed it. A further worry if it were stripped down and further damage discovered.
Any advice greatly appreciated
