Mercedes C180 (W203 - M271) Kompressor Head Gasket Replacement Part 3 - FGep30 

Yes

Hey mate, sorry for the late reply. I don't know them off the top of my head but I recommend you purchase a workshop manual. It will have the information you need.

Mirarty if you know what you’re doing but you’re working at home and taking your time; maybe 2 days?

Thanks for the kind words! Sorry to hear about your motor, but no I didn’t slim the head, just made sure to clean it really well and reinstalled. There was no damage to my mating surfaces and the car doesn’t get driven hard so there was no need imo.

@@FuryGarage Do you have the torque settings for the cylinder head bolts? I am almost done with mine, just ready to put it all back up togather

Starting in the middle and working your way out to evenly torque down the head, the torque settings for the M271 from the haynes manual I used are as follows: Stage 1 - 45NM. Stage 2 - 90 degrees. Stage 3 - 90 degrees. Good luck mate!

@@FuryGarage Just a quick note bud. My car came back to life last weekend, started right up. Thanks for your videos, saved me close to $7k I was quoted to fix it. You are a legend!

Very glad to have helped mate! Good luck and happy driving!

Eric Evans I think I found it on eBay? I can’t remember to be honest. The book wasn’t the best but it was enough to get the job done.

Jackson McCarthy I thought so too, but keep watching these videos and you’ll find out where it actually came from later ;)

It sounds like bent valves but I can’t be certain. Maybe a bore scope or a compression test is a good starting point. Good luck!

Hi, thanks for the comment, as I am not a professional Mercedes mechanic with a well equipped workshop it took me maybe 4/5 days to do this job start to finish figuring it all out along the way. So presuming the technician has done the job before and there are no major unforeseen issues, I don't see why the removal of the head and the refitting will take longer than two 8 hour days. However, I have nothing to add for how long it would take to replace the valve stem seals. Additionally, all of my above estimations are based on my own very limited experience and may be completely wrong. I hope this helps.

Just checked with the Mercedes accredited garage - he said he'd really want to take the head off, wouldn't be happy trying to shortcut by leaving the head on and doing the put-rope-inside-the-cylinders trick to keep the valves up while refitting the seals like I'd hoped. Even so he was happy to agree 2 days should see it done. He did suggest though, maybe my engine's smoking on startup not because of valve seals, but because of worn turbo bearings, which would be a bit quicker to fix. I understand most of the M271's had superchargers but mine's one of the later ones they did put a turbo on instead. He said he's never seen a M271 that needed valve stem oil seals, guess that's a good sign. Anyway you're a star for making the vid. Nice 1 thanks :)

Hey mate, I had water in the oil and oil in the water. But it turned out I didn’t have a blow head gasket. I actually had a broken oil cooler which is integrated into the oil filter housing and it allowed the Coolant and oil to mix. If you want to know if your head gasket is blown, try a compression check and a coolant system pressure check too. They will help you determine in you’ve got a blown head gasket.

Craig Hitchman sorry mate, I have no idea. Best to speak to a mechanic who can hook it up to a diagnostic tool. They should be able to figure out the issue.

a qualquer momento irmão

I have never worked on a 2012 Mercedes. However the general process won’t be too different from the one depicted in my videos. If you have never done a head gasket before then I would advise against it. If you must do it then get an experienced friend to help. Failing all of that do as much research as possible and triple check everything you do. If you make a mistake with the timing change you can destroy your whole engine as a consequence of a potential mistake. So again I recommend you do not do this job yourself.

Fury Garage that’s what I been doing research I have done moany things but never a head gasket and I can’t find a manual for it I have the same engine m271 evo but mine is 1.8 turbo

Elias Hernandez if it’s an m271 then it should be fairly close to what I have done in these videos. You can also try this workshop manual: haynes.com/en-au/mercedes-benz/c-class/2007-2014 Other than that there’s not much more I can help you with. Just be extra cautious with the timing and cams.

Fury Garage thanks those manuals are for the Diesel engine

Elias Hernandez my mistake. Good luck!

Justin Klazinga if it jumps a tooth the valves will be out of sync with the pistons. The pistons will then hit the valves and bend them. This will likely destroy most of the engine. This is not the case with all engines but is apparently very common with this specific engine

@@FuryGarage isn't there a marking on the harmonic balancer indicating TDC so you can align the cam phasers and the pistons?

Justin Klazinga yes there is, but this was the first time I had done any work on the timing system of this type of engine so I was a bit nervous. Thankfully it worked out just fine in the end.

@@FuryGarage Ah ok. Thanks.

Hey mate, I have no idea, I sold this car years ago and don’t play with merc’s anymore.

The broken one inbetween the cylinder and water passage

I cant find a name or replacement anywhere

Sorry I’m not perfect mate, I was learning as I was filming.

Alfie I’m not super well read on the model variants. If it’s not a 208 could you please tell me what it is?

If is a C class sedan is W203, if is CLK coupe/convertible is W209 . Unfortunately I cannot see well the model because both have the same engine M271 and engine compartment. However from the headlights look this is a C W203.
