m103

Hi there, I have a 190e 2.6 with standard manual tranny which was registered in 04/88 that has an engine number M103.942. Basically... the engine as gone dead! :doh: so I have decided to go for the M103 (12v) 3.0 Ltr as a replacement:rock:. But the issue I have is which engine to go for...

I've got a bit of a problem with my idle in that it pulses between about 500rpm and 700rpm (roughly). My car is a manual W126 300SE and when I dip the clutch and the car is still rolling the idle is fine, but the pulsing idle only occurs when the car is fully stopped. Also, it makes no...

Wanted: M103 water pump: part number 103 200 3701 For 1989 W201 2.6 auto W124 M103 3.0 engine may well use the same part. Please PM me if you happen to have one tucked away. Thanks Steve

Below is a link to the cold starting in question. I know that they should cold start better than this, but it has always had the same problem. Hot starting and any start after the first cold start of the day is instantaneous. Any ideas how to repair it? YouTube - M103 Cold engine start

I have just had the head gasket done and the head tested.it needed some welding,which was done.I have done about 400 miles now and have some problems.I managed to get 30MPG four up and full of luggage!! Firstly before the gasket was changed it ran around 90'C.It now runs at that when driving...

I just bought 6 new spark plugs off an ebay vendor. The plugs are new & unused but the boxes are a bit bashed & they look like they might be NOS. I thought it prudent to check the gap & not knowing what it is meant to be looked on the internet. There seems to be two schools of thought: 1) go...

I am having the head gasket done at the moment and when stripping down the guy doing it found the above bracket had almost sheared right through.There was corrosion were it had started to go and it was about ready to fail. Anybody else come across this?

Can anyone recommend an decent oil for my '92 300E.It will be doing around 6K a year of mixed motoring.No oil usage and I think it has castrol in it at the moment but can't be sure.

Does the exhaust head flange on a m104 manifold fit on a m103 head?

The SL has been off the road for the last 9 months and due to work/race commitments I just didn't have time to deal with it. So feeling suitably guilty for the last few weeks I set about it swapping a load of parts and getting it ready for MOT. All new brakes were fitted...

Hi I wanted to ask i have a 190e 2.6 manual M103 engine, and i was looking to do a transplant to M103 3.0 and i was wondering is it just a straight engine swap or will i have to change a few things such as ECU etc?? Thanks

I have a 1989 300TE with the M103 in it, I recently torqued down my head and had already set the creak to TDC..... My Brother in Law came over to "help" and now I have an engine that is no longer set at top dead center, the cam is obviously not an issue but the timing chain was not on which is...

Hi having probs with engine when idling its very rough but when driving and accelerating everythings fine? Changed leads, plugs, rotar arm, dizzy cap? anything else it could be, also changed the ovp relay. it is a M103 engine 3.0 thanks in advance Owen:confused:

Hi, This is my first ever post. I have recently purchased a gorgeous 1988 300 SE. She sounds healthy but give's out a burst of blue smoke upon sharp acceleration. I have read many posts and now believe this to be valve seals? If this is the case would replacing them be the most thorough fix...

As the title says, I'm looking for a sump pan for an M103 3.0l engine. Anyone have one buried at the back of the garage or loft, they don't need?

Hi gang, I'm looking to replace the HT/Ignition leads on my '91 124 300TE. What are peoples views/experiences of the best type and source for this engine? I expect OE MB leads are going to be the preferred choice, but if we're looking at a lot of cash then it might be worth me waiting to...

Well my Brabus 3.6 has eaten its way through yet another headgasket :(, thankfully I have an MLS gasket that PUMPISH (guy the mercedesshop forum who's putting out 600bhp from m103s!) made for me. I've been losing oil in this car at the same rate (~1L/300mi) I had done before the rebuild last...

Last night I noticed that the pressure gauge on my W124 dropped quite low once the motor had warmed up. When cold, and in 'Drive' the marker sits at 1 when I press the accelerator it jumps to 3. However, when the motor's warm it drops to nearly 0 then, as per normal, jumps to 3. I change...

When we did Paul's (JpsKiller) 3ltr Head Gasket we decided to do a howto. Its rather long so please be patient. I won't be able to complete the thread in one go as there are 40+ pictures and descriptions to go though. In the beginning take one 3 ltr engine and notice the oil sprouting from just...
