I just did my first headgasket EVER on M103 3.0 on 1987 300E. The car ran fine but had an external oil leak. Running great now! Just purchased a 93' 190e 2.3 also leaking oil will probably do the head on that. The material is 30+ years what do you expect people!
Personal experience with om603 engine. In my case exhaust was pressurizing the cooling system. You can check this if overnight the radiator hoses still are still stiff when the car is cold. The other way they fail is at the #1 cylinder oil passage. This allows oil to be injected into the cylinder. If enough gets injected, the first cylinder rod will likely get bent. Hence the rod bender nickname. My understanding is that religious checking of the oil level is key. If you are using about a qt of oil every 1000 miles you should be concerned. Bear in mind, valve guides, seals and external leaks should also be considered in that assessment too. If your engine is otherwise leak free you'll have to be concerned with the internal issues. In my case I had 0 external oil leaks but pressurized cooling system after sitting overnight. Imo the ideal failure. I had my head gasket done and still have the gasket on my wall of examples. Wish I could post a photo. Failed in several cylinders due to lack of maintenance. Change coolant out regularly to prevent corrosion. After the change I went to zerex G48 and distilled water. Used MBZ head gasket if I recall.
Hi! I have a w124, M103 engine (2.6). I have changed the head gasket, done a valve job. Now it is not leaking oil anymore, but if I drive it on the highway, because of the high rpm, it consumes a little bit of oil. I have done an oil change almost 4000 kilometers ago, and now my engine oil level beloved max, heading to the half of the dipstick. Could be the oil rings on the cylinder heads?
Hey, I am looking for some help on carb adjustment for high altitude. Driving my '66 200 to denver from KC and I want to make sure ill make it up that long hill ok 🤣.
Pierre does the m102 engine head gasket issues also applies to the ones that are installed in the w123s ? and does the m115s have the same head gasket issues as the m102s
Another great video, I have the M103 motor, and starting those leaks at the front and the rear corners, I’ve read other owners doing a retightening of the head bolts, and have had success, any thoughts on this method,,,thank you
I tried this one friend. Didn't work for me at all, I changed the head gasket and that did the trick. The material cracks and leaves small gaps for oil to escape. It was my first head gasket and wasn't too difficult. Good luck, don't let the job scare you.
@@livin4today132 The front timing chain cover leaks oil and so does the camshaft seal right into the distributor. I replaced the seal and MB forums told me to use Hylomar Blue to seal the front timing chain cover. Maybe its just the front timing chain cover, check if the headgasket leak is leaking down the block under the freezer plugs. Mine was out after 200,000kms

How much does it cost? Head gasket always brings fear but I guess it’s worth paying for
@@joshfgfg Elring head gasket kit $80 Canadian dollars, valve stem seals $10 for 12 valves, headbolts $20 plus other stuff.
@@cromanczuk oh, always imagined it was like $2000 write off amount. thanks Chris
@@joshfgfg only if a shop does it. If you buy one of these cars you should be doing the work yourself, if not well hopefully you are wealthy.
Please go over the 603s! That's what I'm in the market for. I love the look of the W124s, I'll be going after a W123 next though 😁.
Another great video , this information isnt easy to come by!
Thank you Pierre, your first hand experience and explanations are always captivating!
Thanks
OM603 - Yes please, as always very informative,
Cheers from DownUnder.
Great info 👍

My 190E 2.3 had its head gasket changed at only 62k miles according to the Carfax

wow I thought the 87 degree thermostat was the one i should use for the M104 engine. thanks for warning
I can confirm my 190E 2.0 M102 engine started mixing oil and coolant at over 200k miles
I’ve been searching for 80 degree thermostat for my M104, any recommendation?
would replacing a head gasket with arp headstuds and a metal head gasket solve the issue permanently?
Hi Pierre, I cant find a new headgasket for my 250S....NLA. I can have one made from copper.....have you had them done and successfully?
hello where can i find rings and overhaul kit for a Mercedes c200 2007
I always thought the oil leak was just my valve cover gasket. I’ll have to check for head gasket failure. Can this be found with a compression test?
Hello so when you work on engines do you automatic change temp gauge or you ask the owner first or do you just do it?
So my M103 (W126) is in the list
Definitely!!same as mine
Pierre does the m102 engine head gasket issues also applies to the ones that are installed in the w123s ? and does the m115s have the same head gasket issues as the m102s

I’ll check that, thanks for the help,,,
My 190e 2.3 has a completely new cooling system and it has always run hotter than my other mercedes. I think the heat is what causes failure....
How about the 119?
85 300D I know I have a blown head gasket or cracked head is there any kind of test that will tell me which one I have?
Yep..did my M104 gasket at 142k.
I’ve told stories of mental and physical trauma in the very room this man sits
4K?
Video resolution of the video.
My 1985 617 Turbo needed a new head gasket at ONLY 250k miles. Mercedes just doesn't make head gaskets that will go for 36 years!
What about 103
So if I'm hearing Pierre correctly all 126 V8's in other words.
And diesels w om603 engine. However, any engine if improperly maintained will eventually have a head gasket fail. Chemistry is real
