Maintenance on KMP259

[Dimis]

Apologies for the stupid question... humbly, what's the real advantage of knowing how much came out?

Is it tell you how much you consumed? or how much you need to put back in?

I still like to use the plug in the bottom, I know your dry sumped, but on a pan the screw is sometimes magnetic and you can see if any particles are stuck to it, I also think it ensures that all the oil came out, no matter what, your set-up is nice, car still looks cool...

Interesting stuff Morris - thanks for posting. I'm always amazed by how pristine that aluminium front dam looks. One would think that with all of the track work it would take a few chin-plants into the tarmac every so often.

Quick story .... at one of the Run N Gun's .... my brother went off track going in to the S's.... and I kept telling him he was to slow thru that area of the course..... so he went out and didn't lift going into the S's.... and this time he flew off the track and the splitter acted like a Landscapers Sod Machine and shaved up all of the grass at about 2" deep around the S's.....I was eager for him to come in and asses the damage..... thinking it was going to be folded up or the whole lower side of the nose was going to be folded under..... well.... when he got into the paddock ...we took the Nitrogen bottle hoses and turned it up to 300 psi and blew out all of the dirt and grass from the radiator and front of the car..... what a mess.... but when we got it cleaned out ..... not only did the Splitter not move but you couldn't tell except for one little scratch on the passenger side of the splitter that anything ever happened...... it's a good reminder to this day.

So within 10 minutes we had him back out on the track doing laps again.....

Except this time I told him to try feathering the throttle going into the S's....

Worked much better and he did good .... and we tested the splitter the Red Neck Way.....

We use magnets in the Canton oil Filter end caps..... on both the pressure and scavenge side of the dry sump pump. This captures any metal particles that are floating around in the oil. and they work well for us to inspect as well.




The idea of evacuating the oil out of the motor turn out to be a good one that Mercedes came up with and we used it on KMP259 .... especially with that belly pan.... it's torqued into place on the frame rails and changing the oil had to be done another way. The good thing is that now we can see what we are dealing with and can help us diagnose a problem before it happens ....

And then we have to evacuate the Dry Sump Tank and then run the motor for approximately 4 minutes at about 2500- 3000 rpm's and then evacuate the Dry Sump Tank again ..... that get's the other 7 Quarts out of the motor and oil Cooler. lot's of oil in this car.

When you evacuate the oil in a container you will inspect the oil for contaminants like Water,......intake manifold leak...... also how much you get out verses how much you put in, is it in the catch cans or on the ground....... The cloudiness of the oil for aeration of the oil..are we creating air in the system........and in general get a good sample from the tank to send to the Analysis.
