Oil Pressure Gauge and Warning Light Install

- One of those things I wish I did earlier on the E55 but still not too late to save the SL. This car does not have to same pump as the E55 but there's many other reasons a car can lose oil pressure (clogged oil filter, clogged pick up strainer, worn pump, broken chain) and all of these will not get detected by an oil level sensor.

Definitely doing this! On a standalone ECU you can also set it to automatically turn off the engine if the pressure falls below a certain level.
Good advice! I'll look into something like that for the E55 possibly
You can actually figure out how to do this using a timer and relay. If the pressure falls below a certain level for x seconds, the relay disconnects the ignition. Should be pretty simple, actually.
wouldn't you loose powersteering and braking? and get steering lock?
@@nirfz on semi truck you get message of engine shutdown and you have 10-15 sec to stop.
@@nirfz you will loose power-assist indeed, but not lock if you have a key
not an issue with old-timers ;) my m103 used to cut-off just on its own while driving for ex ))
Great job!
u think this O ring issue is actually something ppl should be worrying about?
Alex i've been following your videos for a while and am a big fan of the channel. Your input here would be greatly appreciated. I was going to comment on one of your video's but you haven't posted a vid of your wagon in a while.
My question is do you think this modification is worth doing, as I want to modify my E55 and make a full build similar to what you did.
That being said, obviously I don't want my baby breaking down and all that $$$ lost because of this. As you have the experience of a Mercedes Tech and your YT, do you think you could do this install on your E55 or at least address this?
Thanks so much and I would really really appreciate any input.
Thank you so much for posting this!
It made me look on my 2006 T1N Sprinter for a similar tap line (before drilling and tapping one myself!) I'd found nothing online about the existence of such a tap line and indeed I read a comment by one guy who drilled and tapped one of his own.
Threads in my engine are M10-1.0. Thank you!
Great vid. Yeah, none of the M112 and M113 engines have oil pressure sensors, pretty stupid from Mercedes.
Not pretty stupid. It is pretty devilish to win money.
Nice Video, my S32 AMG project were pause by a bad oil pressure and damaging the engine.. good to see your video so i can prevent the worst case! Thanks!!!
The set up with the oil line is a million times better than having that thing hanging off the block.
Great video, professional, complete, straightforward. Will be doing on my E55. Thanks.
beautiful SL you got there
What a great follow up video!
Excellent solution to have redundancy for both indication and measurement for your oil pressure. It is a very easy install and I'm baffled why Mercedes doesn't even include it in their cars! It's just insanity in my opinion! Hiding the oil gauge in the dash is really cool solution. Cutting into the compartment is a life saving procedure and doesn't reduce the value of the car, considering how essential it is to have the light indicator and corresponding oil pressure gauge hidden in the cubby compartment.
I agree that rebuilding the second AMG engine you bought will allow you to make it better and more robust, especially if that very engine blows for another reason. This is one of the reasons why I like buying refurbished products, because usually they're made better with updated components that what was previously used, at a reduced price.
Look forward to your build videos when the crank bearings come in. I'm not sure why these are most important to have first, but I know you'll explain and demonstrate why in your video featuring that install and measurement.
I learn a lot from your videos and the detail you provide.
I'll definitely come out to see you race once your car is put together and working as you see fit.
Keep up the good work!
Thanks. Wanted to get the crank and con rod bearings first so the clearances between the bearings and crank can be measured. I'm sure they should be fine but its an important check before rebuilding an engine. If the crank has worn down too much or the con rods have opened up the clearances will be too large and I will find out in time.
That looks really clean. Well done
Good work man, good to see at home mechanics doing proper work,
next time when u teflon a fitting use the teflon anticlock wise so when u screw it on, the teflon will stay on the threads.
keep it up bro
Thanks! Wanted to do it for years on m112, going to order a sensor now.
Most usefull tunning ever for that engine!
Dont understand why it never came with an oil pressure warning light which is standard on most engines .
I guess Mercedes have wrongly specked the material they use for that o-ring. Mercedes make a lot of engines that work in various conditions - they should know better. I would ask at a Mercedes authorised service point if there is a maintenance update concerning this o-ring.
As far as the oil pump chain marks are concerned, Germans in general use tensioners on the oil pump chains - I would check the tensioner for wear as well as the spring on the tensioner for the right pressure. I don't know your specific engine, however like I said, BMW, VW Mercedes - they all use them and the scratching effect due to weak or worn tensioners is known.
btw - very cool video - thanks for sharing and documenting your work!
Thanks for giving awesome ideas in your vidros.
You can rotate the pressure indicator 180 degree and print out a new background picture with also rotated numbers.
Great work on a follow up video.
You're a PRO by all extend means AMG should make you the CEO and adore your talent/knowledge for the rest of your life
I’ll also be doing this on my 113K motor, thanks for vid
how much must be a normal oil pressure? in case of mercedes c320 with m112 this job should be similar right? and what about the normal oil pressure that should be running onj?
hello can this be done to a first gen pajero? I have a pajero which ive change engine from 4g54 to 4d56. I dont know how to connect my tri guage oil pressure guage to the oil sending unit.
MR. XF, don't forget to tell someone else driving your car [ha!] that that light means THAT.
Great vid, thanks! I will be wiring up pressure and temp. Do you know if an oem mercedes pressure sender work with an aftermarket gauge?
What if the oil pressure is too low? Do you have to stop immediately? What to do next, restart the engine, or try to find to cause of the low oil pressure before starting the engine? What is the normal operating pressure for Mercedes, 3bar? If it is 2bar, can you still drive the car normally or does it mean that there is something wrong?
Where did you get the turbo oil line kit? It’s perfect with the T also! Thanks for a great video!
Good job Pal!
Finally someone who did it right!
Is is also recommended to install an oil pressure sensor on diesel Mercedes or is it nor really necessary or non powerful engines?
Can you do a video on how to install a boost gauge on the m113k supercharger?
What's your budget on rebuilding the engine? I'm in the same situation where a used engine needs a rebuild. I feel like it's better to rebuild it and know what I have, instead of taking chances with some random m113k.
Didn't you have to bleed the line? (Or did you just not mention it in the video?)
Nice video. What is the purpose of that bolt/plug you removed from the engine in the first place?
Great Good and a real good point P.S. You should turn that gauge upside down from where u installed it so u can see it better
Going to be the same process for m113k e55?
Good video, ive been doing these types of mods to my cars but its getting more difficult as cars go canbus. I was angry my Volvo has a buzzer for the seatbelt but nothing for engine warnings, atleast my 2001 volvo still has a oil pressure light that i intend fitting a buzzer to.
Nice job 👌
Will the switch also trigger at high oil pressures for when part of the oil galleys where the be (partially)blocked by what knows happens, not sure if it would result in a significant enough increase in oil pressure to be of any use. And also I would add a sound as well for the track driving.
There would be a drop in pressure if the oil filter or the passages before the filter get clogged. Oil passages after the filter usually don't get clogged unless the filter fails or too much sludge builds up. If they do get clogged it would be really hard to detect because even the oil pump has a pressure regulator and won't go above a certain pressure. I guess you just have to have faith in your oil filter for that.
sludge build up would only be a issue if you don't change your oil at correct max mileage oil change (i norm half it witch is 5-6k miles)
still can't believe there is no oil pressure sensor, but the manual omittance of the oil pressure light can be a give away that it lacks the sensor (as it only has a yellow low oil light there is no second Red Oil pressure light)
Woah u got some heavies commenting here now! Great job. I'm gonna do the same.
Btw do you know if the m113 non k has the same o ring on the pickup?
And did you upload the video of you changing the rocker arms on ur old engine? Thanks man!
Yes, I believe all models with the two oil sumps have that o-ring. No still have to upload that and the tuning part lol. I'll try to cover it in the engine teardown or rebuild video since I have to rebuild that engine anyways.
Good idea👍👍
nice tutorial! I'lll probably do the same mod to my c140 next week
c140 already has op guage
ray croal but it's not being displayed in the extended menu of the instrument cluster :(
Do you have the part number for the switch?
When u rebuild this engine, the main bearings are different sizes, the block is marked with numbers and you’ll have to order basically 2 sets of bearings. The main bearing caps were all reds, and the block side bearings were yelllow, yellow, blue, yellow, blue. I originally ordered all blue ones, and checked the clearances and they were a bit off. Mic the crank, and if that’s within spec, follow the bearing size that’s stamped Into the block.
Yes, you are right. There's 3 different types for the block and 5 different types for the end caps. The letters for the colors are also engraved on the crank. Makes it extremely confusing to order but hope the clearances work out.
SK8215 you’ll be able to get em, but it’s gonna cost, since they couldn’t order them a 1/2 shell at a time I had to pay for a both when I only needed 1 half! Good work I enjoy your stuff
This should save your new engine =)
install buzzer instead of oil warning light, it will get your attention even if you looking only at the road.
Hello SK8215 , i'm also in Canada Mississauga Ontario, i see you have very good knowledge about Mercedes, im wondering if you working on the side thank you .
Heyy I need little help please.. I bought the same oil pressure gauge did the installation but mine doesn’t work.. I didn’t connect the wire to light up the gauge.. do I have to do that for the gauge to function ? I thought it wasn’t necessary but I don’t know if that connection is the problem or if it’s another thing..
Thanks and great video 👍
Connect first everything under the hood, bleed oil line. When you will get it working under hood than move the gauge inside cabin.
Can you list the parts here please?
Heads up that the keys to these vehicles are no longer available from Mercedes. That's right, lose your keys, no more driving! Call MBUSA and let them know they need to FIX this!
VDO has an oil pressure sensor with an internal oil pressure switch (switches below 0.5 bar) so its a 2 in 1.
Are you sure you have a good ground with the teflon between the block and the hose?
Thanks for sharing 👍
Didn't know about the oil pressure sensor 2 in 1. The ground seems pretty strong. I tried it with a 3W light bulb and the ground remained 0 volt so I didn't bother running an additional ground wire.
SK8215 This is the sensor i have on my cars: vdo-webshop.nl/en/pressure-senders/386-vdo-pressure-sender-0-5-bar-1-8-27-nptf.html
@@jonathan643 How do you wire for the pressure switch separately? What do you wire it to in your cars? I'm thinking some kind of shift light hidden in the dash but shining right at my face! Thanks!
Nice Job. The oil gauge is universal but the oil warning light? How do you know is going to light up when you need?
Its from a standard oil pressure switch. Whenever the oil pressure falls low the switch shorts to ground and lights up the warning light. It comes on when the engine is off and turns off when the engine starts and oil pressure builds up so that means its working.
Would it be good to have an audible alarm for the oil pressure as well? Seeing as how you might be tunnel visioning on the track and not catch the warning light in time, before you explode your engine?
Yeh, I was thinking of connecting a relay with the door circuit so it triggers the door open alarm if the pressure falls low. Probably something I'll try for the E55
older Mercedes (80's) had a real annoying buzzer for "lights on - open door- keys out" that would be the ideal sound...
Is the oil pressure gonna read correctly? Since there is no oil really flowing thru the oil line extension. Just curious.
Jason thinks as if it where air, it wants to be at equil pressure and because the meter is connected on the side it wil read the pressure that is present where the oil line begins.
Marko Held: if it isn't bled out, the oil will compress the air inside the line and the gauge will read an airpressure. If that is the right way to di it ok... i don't know, but 2 thinkg would worry me: 1. air is compressable so is the pressure it shows really what you are looking for? 2. when the oil gets hot the air gets hot too and hot air wants to expand which would show an increased oil pressure on the gauge readout. (without the oilpressure being any higher.)
Pressure is pressure. If the hydraulic oil is used as the force to move a cylinder or in applying brakes then the compressible air would compress instead of moving the piston and that is a problem. In that case the air needs to be removed. In the case of pressure gauge the air will compress to the same pressure as the oil and will deform the diaphragm in sensor and read the same.
Thread ressurection. I am curious about this to since there is a flat gasket on the inside of the plate/plug. Do you remove the gasket so the oil reaches the sensor or does it get compressed by pressure and then pushing on the sensor?
Where can i buy these parts?
What happend to Mercedes the old ones Always had a pressure gauge
Chrysler engineers happened.
saved a few bucks...
Fellow Mercedes fan here. I hate the Tele-Aid option. PITA for us poor folks who pick up a Mercedes and find out the rest of the car is pretty easy to work on, but there's always something dumb. Hopefully I found a mechanic that can do it (All Town Auto is $102.50/hour and Dealer is $157/hour) No idea if anyone can delete Tele-Aid.
Hi! Wich pressure value is good and wich not?
I've been seeing between 20-25 psi at idle once engine is warm. The highest I see is 75psi when reving high.
The oil I'm using is 20W-50
excellente
What kind of oil use for this M113 motor ?
20w-40 на свежем, 20w_50 на проходившем, но говорит что 50ку тяжело найти.
Class
So Mercedes made an oil pressure port on the engine and left it ?
so that someone after a few years will realize that the engine sucks without a pressure gauge and that it could be installed on that port :D
It's for test purposes
@@bicylindrico Exactly! The process is described in detail in the Mercedes WIS. Best regards from Germany. Michael 🙌
Hi, where in TO do you race?
Usually TMP and Mosport
SK8215 thanks, your knowledge is impressive, hopefully I’ll see you on the track some day, cheers!
Would like to do this on my CL55k
you could just buy an oil pressure sensor with integrated pressure switch its like a combo 2 in 1.
Great job. I recently followed you because I'm interested in AMG Mercedes and it was a suggested video. You could change your channel name to AMG racer or something because I had to think twice who is behind SK8215. That way you would attract more viewers and subscribers.
cool
Why didn’t you just run a mechanical oil pressure gauge? Much easier and I think more accurate.
MAN U R SO COOL , I wish i am you hhhhh
Warning light from the factory is too late anyways
Well done, but you can say it Pakistani " jogard" lol
Dang, can anybody just do a how to video without talking so freaking so much?
