Well lets sharpen our pencils and see what that would cost. If you cant get your mind around the concept just buy a puller. Originally he told me that he sure made it sound like they benz will pay for a big chunk of total repair bill. I spent another few hundred on tools. The inline engines are a tad different. While timing chains typically last the life of your engine, in higher-mileage Mercedes vehicles, the timing chain can start to wear and stretch, creating problems that can lead to engine failure. In some situations I believe the guides and rails can be the actual cause of chain failure rather than the chain itself.
Having just had exactly this problem on a 2005 C180 Auto Kompressor with only 57,000 miles on the clock - which has cost be over £1,000, I would recommend doing a bit of preventative if you can. Leave enough slack that you can use the wire to suspend the timing chain. Even though I have done all the proper oil changes sooner that the mb recommendations. When the guide jams up in gears it usually causes serious and catastrophic engine failure that almost always bends the valves on the drivers side head and in real bad cases will even crack the valve cover! When that happens say goodbye to about 5-8K unless you like doing head gaskets. At this mileage, all this stuff should probably be replaced. In a well-maintained engine a timing chain can last up to 300,000 miles and even longer.
Bolting it up compresses the piston and will push some of the oil out and dampen it before the oil pressure takes over when the engine starts. Many autos have two or even three chains in their motors and often your auto repair shop may recommend replacing all the chains at once. This is because as the chain wears out, it stretches and the ignition and valve timing becomes more retarded. This guide was factured in the center. If the timing belt has signs of wear or has a rattling noise, it should be replaced immediately. While this procedure is shown with the intake manifold removed, removal of the intake is not necessary and is removed on this vehicle to address other seal related maintenance not related to timing chain guides. It could fall in the engine.
Never a reply for over a month. It is possible to strip and bend these pins. He blame me for not taking my benz to for all mechanical issues during possession of my vehicle. However they read like there are a few redundant charges. His theory was that if it's not acting up you introduce risk by changing it.
The simple answer is No, it is not. At the very least pulling the cylinder heads will make for a cleaner re-install of the timing cover should you elect to replace the lower block mounted guides. This level requires that the radiator, fan, fan clutch, alternator, air pump, power steering pump, air conditioner these two can be unbolted, but their hoses still connected, poly belt, its tensioner, water pump and it's reservoir anybody know what that thing is for? The timing chain noises can range from rattling to whirring, whining or buzzing. Another shot of the guides installed with the sprocket. Best of luck and go slow and careful. Also show is a makeshift pin puller fashioned out of regular tools and some spare valve cover bolts.
Where any other manufacturer would use 2 bolts, Mercedes uses 6, and at different angles, lengths, head type, etc. Might as well grab some new spark plugs, dist caps and rotors- might also consider new spark plug wires if it's been a while- definitely change the water pump and thermostat, and consider the poly belt tensioner- update it if necessary, poly belt and radiator hoses at the front, as well as the voltage regulator in the alternator. The vehicle was not repaired. If some of the other 350 owners would like, I can post the part numbers for my 116. Maybe in the next few weeks I will post up photos of how to roll a new timing chain in, however it's important to remember that if you are going to replace the chain the guides must all be installed prior to rolling in the new chain.
You can also use a marker to draw a line too. Here we have re-installed the cam sprocket. I meant to say so the other day but this kind of info is what this place is all about. How Important is Timing Chain Replacement?. Do I really not need to worry about our M103 now showing 180,000km with its single row chain? What about the penalty in terms of mis-timing? The check engine indicator also illuminated.
They never mention no such thing, and now making excuse to blame me for them selling me a lemon. This is located directly underneath the name and price of the service you've selected. Any help would be great as I've just got this engine in from a professional and done a lot of work, money, and time into it because I really love this car and it is fun to work on. They are both very solid - the 103 because it's so short and the 104 because it's double. Two points of care not mentioned - to replace the sliders you will have to remove the sprockets whether you change them or not, just to give adequate clearance for removal and replacement of the slider pieces. I would hate to imagine what it would cost to pay someone to do this.
I would ignore that lower rail. From what I've read on this message board, failure of these guides is what frequently leads to failure of the chain, or the oil pump. Now I am driving this vehicle with the check engine light on because of the problem I mention above. Benz salesman never mentioned that to me. Question is does crankshaft sensor come up on computer pr it can happen just like that, as I never had problem before just drove home and after few days when my car wasnt driven I couldnot start it.
