It's alive !!! M113 turbo Start Up !! & oil pressure issue !!!
Okey. I will start at the start up because that is what most people want to know i think. I went very good. Over the last few weeks i put y start up file together and checked all the input and outputs. place all the parameters according the wiring that i used. discussed this with the tuner. And had some small changes to make it perfect. When starting i had the signal from the trigger incorrect. it need to be a rising signal and had falling signal selected . when this changes i had a RPM signal on the crank from without spark plug 185rpm and with spark plugs 140rpm.
First real start attempt i had a big bang in the exhaust 1 time and after this nothing . I had this before with my 190 V12 in the past when starting for the first time. The Home signal input was incorrect so it is firing 180 degrees wrong. so changed this value. After this attemp i put the cranking enrichment on 0 because i had already some fuel injected in the intake from the previous attemps. So next try was spot on it was running pretty easy in about 3 engnie cycles.
The first thing to notice. was that it was running very rich. i had to pull about 25% VE out the get the AFR target. when had it running up to 30c coollant temp i could let the engine idle just on the idle control.
Next few starts is getting everything better adjusted to get the chassis alignment done. And getting it ready to do the street tune. After this i have to do the road legal checks. If this is all done it is dyno time!!
So. Oil pressure issue. This what i always do when i don't now the engine or it is along time standing, rebuild or else. I want to see oil pressure on the engine and what to see without compression build up. So now sparkplugs in the engine. Fuel and ignition shut off. My engine is fully rebuild so everything except the cylinder bushings are in assembly lube incl the oil pump. pistons where in engine oil same as cylinder walls.
I had and oil pressure gauge on the pressure side connection of the pump on front of the timing cover. I cranked the engien over for 4 times, 1 min at the time to give the starter some cool done period. The info that i had is that it can take 2 min to get oil pressure. Because i was not building compression and just running on the starter with full assembly lube there can not go much wrong. but i inspected the cylinder walls to be sure. But everything was okey.
i got in contact with some friends. Also people with experience with mercedes and thes era engine's. When the oil pump is removed or after long standing the chamber between the pressure side of the pump and the check valve up in the engine can loose it's oil capacity and when this is empty the pump can not build enough pressure to overcome the spring pressure of the check valve.
Drained all the oil, removed the oil pan, removed the oil pump..... see picture below. complete dry.... filled up the pump and pump oil through by hand. Get all the air out. mounted everything back .
Cranked the engine again. took 20sec oil pump full pressure 3.5 bar on the gauge ran it up to 45 sec. later on another 1 min. Checked all the lines and the cooler . everything full of oil.
So be aware. Check if your really got oil pressure before starting real life

Thanks for sharing your experience, especially the bad one. That helps a lot!

[@thelongranger55]

Yes ! Good work. It’s been almost a year since the rebuild?! I’ve followed along and you’re series helped me rebuild my m113 . Can’t thankyou enough. Hard work pays off!

[@JMSpeedshop]

Thanks 👍😎

[@bicylindrico]

This is awesome! I too had to crank the engine quite a bit on the stand to get oil pressure. I didn't dare fire it until I did but it took a few minutes. Looking forward to more progress

[@uprooy]

Onvoorstelbaar dat je dat allemaal zelf doet Johan, eerst die geweldige 190 V12, nu dit. Als 280SEL 3.5-eigenaar gaat mn hart wel sneller kloppen van die projecten. Geweldig leuk om te zien.

[@JMSpeedshop]

Dank je wel 👍

[@V12Buickguy]

With the Maxxecu you should be using a ZF 8HP behind that thing. They have all canbus control for it now.

[@JMSpeedshop]

Yes but not a straight fit for Mercedes. 722.6 is a straight fit. Also can send canbus signal for shift cut

[@Sera5e]

Very cool, nearly there... and only one leak on the welds? Good effort getting it this far!

[@JMSpeedshop]

Yes small leak on a weld. Already fixed it 😉

[@Rourkeize]

If you have issues with the lamda dying you can make a small table with an activation delay based on engine run time and coolant temp. A few second on hot to 10s cold I think. Saved me from a lot of broken widebands.

[@JMSpeedshop]

When now doing these settings . I run the lambda on . On ecu startup. When i got the base idle settings a table around this correct i will put it back on engine startup. Also running a 4.2 these are more reliable then then 4.9

[@Rourkeize]

@@JMSpeedshop ok I would be careful even 4.2 is easily killed at engine startup because of water vapours. My wideband was about 60cm from turbo and I broke two before this setting was applied.

[@JMSpeedshop]

Oke. I will discuss this with the tuner. Thanks 👍

[@jimmypage4162]

Awesome! You do impressive work man congrats on the complete build. Best of luck here on ✌️

[@JMSpeedshop]

Thanks 👍

Lekker bezig man !

Great job mate!!

Wonderful!

Thanks👍

[@philipc5547]

gefeliciteerd

[@JMSpeedshop]

Dank je wel 👍

[@stansmeets7216]

gave swap en een hele stabiele basis en motor👍

[@JMSpeedshop]

Dank je wel 👍

[@RodrigoVieira-lc9kx]

I'm building a Mercedes with the same mechanics in Brazil, but I don't have the gearbox controller. Which controller did you use to control the 722.6 gearbox?

[@JMSpeedshop]

Ofgear.dk

[@narcissistinjurygiver2932]

I am thinking of getting a r129 with the m104 and putting a turbo on it.

[@JMSpeedshop]

Nice 😎

[@blackbirdsr71]

Be careful with all the idling that don't bore wash. How much boost are you going to run?

[@bicylindrico]

I second this. I avoid any extended idling on these engines and at least maintain 1k or over for any test and tuning.

[@JMSpeedshop]

When oil pressure is correct and idling around lambda 1 there is no problem

[@JMSpeedshop]

No street driving done but on regular full no more then 0.8 and on e85 1.3/1.4 max i think

[@blackbirdsr71]

@@JMSpeedshop cool that you have control 👍 So it original compression ? 10.5:1?

[@JMSpeedshop]

CR is 1:10 on these .
