My car had the same problem. Same motor, the fix for me was to apply quite a bit of the form a gasket on the passenger side of the timing cover gasket. These motors tend to leak there, it was proven somewhere on a MB forum that there is some space that doesn't have anything stopping the oil from coming out. Hate to say it but sometimes you have to cake the form a gasket to get it to work. I usually will apply it and then hand tighten the bolts. Wait about 5 to 10 hrs then torque the cover. This way the form a gasket expands then you squeeze it tight when you torque it. Very nice videos by the way, I'm sure they will help someone!
i don't think the oil leak problem on this car has been solved, ill return to this in few month when i have some free time. Thanks for the info, ill try your method. Maybe it will be more successful.
I don't advise using this method, you get 50% chances. There's a proper way with removing chain tensioner, look it up on my channel There's another video for head gasket replacement
Wonderful Mr Andy...you mentioned every detail. The Diriko sealant has a good reputation here in Kuwait too,some independent techs. here used Original Japanese sealants from Toyota and really worked great too. Now am really longing to know what happened...are there any leaks yet? God forbid. Thanks for the video.
well I drove the car only for about 10 minutes since the last repair and it's hard to say if the fix worked, but I can see a little bit of wetness so I think my leak is coming from under the head gasket. i just have to cofirm that, I will put the car on the road and then will determine for sure if the oil is still coming out and if I see any oil it will definitely be a head gasket replacement. it looks like the previous owner had some work done, I'm not sure who did the job but it doesn't look it was a professional.
Why is this video still up? You concluded the procedure didn't work. Additionally, it is totally unnecessary to use the shim stock. Just remove tension on the driver's side of the chain and pull the pin out. This can easily be done without touching the chain tensioner and allows the cover to be placed on top of the gasket and compressed to clear the locating pins. It eliminates any "gasket movement" or "rolling" mentioned in the video and by others. The engine was designed to have the pin removed (that's why there is an access hole). Just pull the pin and concentrate on RTV'ing the corners of the U - Shaped gasket. Don't overthink this simple job.
Ive tryed to do it this way, because many forums have described this method, some of them even use a razor to shave the top of the gasket, and some want to use crazy glue, all because they dont want to mess with the tensioner. You are right, it doesn't work well. Doing it the correct way is much easier and you get better results.
Hello everyone I have just had my done by neighbor and thereafter I had a new problem, oil leaks into tge coolant and no coolant in the engine oil and transmission oil. Any help please. He is now suspecting that oil cooler is a culprit and must be replaced, on the other hand I do not beave so because before he worked on the car there was no oil on the coolant
Dude, one quesitos i have a w202 c280 1998 and want to Know where is the oil pressure bulb my car have oil cooler under admission, You can help me With that
017-997-21-48 o-ring in this video i made a little shortcut.... I highly recommend removing the guide pin supporting the RHS timing chain shoe (104-052-07-74), it will make cover installation much easier and you won't need to use the shim stock material. Use a 6mm bolt and a number of washers, thread the bolt in and keep adding washers until the pin is out. The pin can be installed later after you install the cover, remove the plug covering the hole, insert the pin. Thread the 6 mm bolt all the way in and use a hammer to knock the pin in. Measure the height of the threaded part of the plug and make sure the pin sits lower then that. It's a bit tight to use a hammer as you won't have much room to swing the hammer, so might use/make a slide hammer.
I'll have to measure it. But I don't recommend using this method, it's gives a 50/50 results. Spend a little more time, remove chain tensioner then pull out the dowel pin holding the timing chain shoe on the driver's side . I got much better results going this way. Just make sure you learn how to reset chain tensioner.
jimbobmedog now im not sure if the cause of the leak is here. I had the car on the road for few weeks and i still see oil in the plastic pan under the engine. i suspect its the head gasket. thats next on my todo list.
AndyP Mercedes Channel good luck with that one I look forward to the video on it. Iv researched it and it looks relatively straightforward accept for a tricky chain guide pins that goes through into the block. But I'm hoping it not my head that's leaking. Great content my friend keep it up.
Thanks. I've done the U-seal twice and the oil leak is still there, not as much thou but it leaks. I have a feeling previous owner/owners had something done to the engine, i can see some signs, the front rhs head bolt was loose. and this cornes is known for leaks Just don't want to play anymore...head gasket it is...as soon as I'm done with flexdisks on the driveshaft.
AndyP Mercedes Channel mine doesn't lose a lot of oil but it's been leaking for years by the look of it. Needless to say my engine doesn't look as clean as yours. Your videos are of great help tho it alway helps to see someone else do something before you decide to give it a go yourself.
what is the purpose of putting the 5thousand shim during the cover installation? I was told there is no need to do that. I would like to hear your reason behind it. Thanks
Its a little cheat if you dont remove the pin holding driver side chain guide. This pin is long and to slide the cover into place you need to start from some distance, while doing this the front edge of the u-shaped gasket tends to get caught and it rolls out of the bottom groove. The shim plate prevents this from happening and ensures that the gasket stays in place. You can see some bad advices on youtube and MB forums suggesting to glue the gasket to the bottom cover or to shave the front edge of the gasket, these are all bad (not to say stupid ways) to install this gasket. A proper and easier way to install timing chain top cover is to pull out the pin. Before removing the cover, find the plug covering the pin. The pin has a threaded hole (as I recall it's an M6 thread), use a M6 capscrew with some spacers (a small size socket ot washers will work) and pull the pin out. If you haven't done this yet you can pull the pin out after you've removed the cover, not a big deal. Reinstall the pin after the cover is in place. Insert (thread) the M6 capscrerw into the pin and drive it in with a small hammer. Do not hammer the pin or it will deform, use the the bolt for this. Just make sure you install the pin deep enough to clear the plug, otherwise the plug will be pushing on the pin and will try to pull the cover away from the cylinder block.
Has anyone here ever heard of an M104's timing chain catastrophically breaking under normal use? I have never heard of such a thing until I had my head gasket done (after 120,000kms) and the first road trip following the engine's reassembly had the timing chain explode. I've owned a car with an M104 before with 300,000kms on it and never had a major repair required.
Hello I had the serpentine belt separate on my 98 s320 it hit the switch and bypass hose ripped the plug off that switch on that front cover can you please tell me how many wires going to that switch there was only 2 wires left and plug gone I think one other wire may had Been ripped out so now I have 5 codes ! The 2 wires I had left was the same exact color I can't find other wire fan ripped it out and its lost some where on the highway I needed to know the color of the other wire and where it is going any help will be appreciated!
@@platinumbenzman front rhs of the engine is the Secondary Air Injection Pump Switchover valve, you should have 2 vacuum lines (one in - one out) and 2 wires. Red/green to Contact 2 and Green/Blue to Contact 1 (based on schematic). I think easiest for you - just go to a junk yard and get a connector, cut the plug with wires just leave few inches. Splice this connector to your wires.
