Chris' (in)practical daily and every expense spared musso

[chris r]

If its going to be slow it may as well be cool (inside)

Chucked the gauges on and it had sfa pressure. Had a small top up can so shoved it in

Compressor and TX valve are doing what they should so I'll get another couple of cans and see how it goes. Sticker says system charge is 750g. Cans are about 250g from what I can find so I'll get two more and see if it starts cooling

[chris r]

Speedo was doing stupid things and when I revved the engine in park it'd say I was doing 20k. Trans also felt like it was trying to take off in second and wasn't shifting nicely 

I thought there may be leaky caps or dry solder joints in the transmission computer. Whipped it out as it was only under the passengers seat. 

Looks mint, did a quick and dirty re flow on solder joints on the header plug and stuck it back in 

Ssangyong barry forum said the tps are common to shit the bed or come out of adjustment and its fairly common for the speedo sensor wiring to have issues. 

Checked tps and it was within spec and the voltage didn't jump all over the show when it moved through its range so that's ruled out. 

Crawled under and had a look 

Initially looked okay when I unplugged it so I dug a bit deeper 

Yeah that's not quite right 

 

De pinned the connector and put some heat shrink on https://i.imgur.com/vIe9Uhc.jpeg

And more for good luck 

Put it all back together 

Got annoyed at the diesel oil schmutz on stuff so took it to wash world on the way home 

Now I can figure out where it's actually leaking from. Bonus it'll be less dirty when I fondle the injection pump and wastgate hose. 

The transmission now actually shifts like it should and doesn't feel like it's slipping or doing dumb stuff. 

It's less slow now the transmission knows what gear to be in and torque converter lockup operates

Stumbled across some old Korean videos on YouTube 

Might need to re index the torsion bars in the front and find some shorter springs for the rear 

[chris r]

Had a thought that maybe the injection pump wasn't seeing boost due to shit vacuum lines or a blockage somewhere

Yeah that was blocked 

Now it's not 

Thought I'd have a quick look at the intake crossover arm 

Yeah that's pretty caked up too

Probably egr schmutz and pcv stuff so may as well reduce the things that could cause the schmutz 

Only the finest of gasket materials 

Needed to block off the egr port on the manifold so used the old valve so the flange wouldn't warp when I welded it.

 

Turns out the valve was sealed and the shit inside the pipe tried to escape as I was welding and was venting through the weld. It's ugly af and still has some pinhole leaks but I'll let the exhaust gas mark them out for me. It doesn't noticeably leak so it's good enough for now. 

After all that work it's still Fucking slow. 

Got annoyed with it and re installed vicegrips on the wastgate line and pulled off the intake arm. That's full throttle and a mild incline. I'm guessing the rest of the intake is going to be full of schmutz so it'll have to come off for a proper clean. While I have it apart will most likely pull the injectors and get them serviced as I bet they never have been done

Grabbed another couple of cans off marketplace and topped off the aircon, it's super cold now so I've managed to fix something which is nice. 

Found a loose clamp on the intercooler. Tightened it but made no difference annoyingly.

Done a pressure test? What's the bet a hose has let go?

It had some pressure when I initially put the gauges on so I think it's just never been re gassed. It did hold the pressure from the first can over a week so it's good enough for now 

[chris r]

Whipped the intake off in the slight hopes it'd be full of schmutz 

Wasn't bad enough to cause this amount of performance loss. 

Since I had most of it apart pulled the injectors out too. Chances are they have never been serviced so it won't hurt to have them checked over 

That might be the problem there 

Gave the intake a quick jizz of oven cleaner, degreaser and a waterblast 

Will give it another go over with more elbow grease at some stage to get the last of the crap out

I was meaning for the intercooler piping but yeah, curious on why the a/c was down as its a closed system

any exhaust restriction?

Oooh my bad!

Yeah I have tightened all the clamps and it made no difference. No signs of boost leaks (I left a clamp loose and saw some oil schmutz escaping and no change after re tightening it) 

No exhaust restriction I'm aware of as I had unbolted the downpipe to the muffler and it was equally slow, that was before sorting the boost feed to the pump though so could potentially be a issue 

It was surprisingly quiet with no muffler so the massive middle muffler will probably end up in the scrap bin with a bit of pipe to replace it 

[chris r]

Injector guy said injectors are a bit worn and the pressure has dropped off but he can sort them. Parts ex aus so will be a few days. 

Had a cunt of a time on wagons ball joints/control arms today so down to zero drivable vehicles now. 

Decided to do some basic maintenance to make myself feel better 

Cleaned out the musso Intake. Pretty sure the schmutz re blocked the boost feed to the pump after did a half ass clean the other day 

 

Did the glow plugs as well since manifold was off 

Gave the ports a quick wipe and clean too. Reinstalled the boost rags into the ports to keep out the environment. 

I had thought that ssangyong had for the castings or something to get the licensed by Mercedes but they must be licensed to assemble the engines. 

Head cast in Germany and genuine Mercedes rocker cover gasket

Intake manifold is also Mercedes but has ssangyong part number on it 

It's also got daewoo parts too 

So it's a Korean made gm daewoo Daimler benz powered thing

Welds so much nicer than the Chinese cast I've dealt with!

 

 

[chris r]

Collected some camber & castor adjustment bolts today. Never felt more out of place or judged for walking into a business ha 

Everything ready to go in 

After a bit of a battle new lower control arm, new castor /front lower arm and new balljoint. Unsure which one wof man failed but the one in the castor arm was fucked and the other one wasn't much better.

Some idiot owner butchered the tube so now that nice plug won't fit. Will keep a eye out for another tube. 

Injectors for the musso are ready, will hopefully receive them this week and can get it all back together before Easter

Injectors arrived 

New heatshields are wrong but others are on the courier and should be here tomorrow 

Torqued the glow plugs

Put the intake on, realised I forgot the throttle linkage. Took it off and reinstalled it 

My egr butchery blank removed and better one in its place 

Cleaned the last of the schmutz out of the boost tube 

And sat it in place 

I gave the alda (boost aneroid) 1/3 of a turn so hopefully it gets a bit more fuel quicker as boost comes on. Cbf pulling the back off the pump to tweak the rest, it'll also need to run so I can make sure that it returns to idle after tweaking it. 

Gave it a oil change too but we all know what that looks like. 

Hopefully after all this work and a bit of money it'll end up being regularly slow not Fucking slow 

[mjrstar]

If you want to make it faster, maybe try running it on petrol instead of diesel. As some petrol cars are quite fast.

[chris r]

Wof sorted on wagon which is nice. 

Went on a barry Mercedes diesel journey. 

Genuine Mercedes crossover/boost tube gasket 

Part number if anyone cares (not many musso left and even fewer weirdos who want to fix them) 

Correct looking injector heat shields

And a new oil pressure switch to replace the one that's leaking oil internally 

Now to install it all in the rain 

[chris r]

Rain stopped luckily but was windy as 

battled with the new injector clips but got them in and everything reassembled. I also had the correct size fuel hose to replace the vacuum hose on the injector return 

 

Cranked it for ages until to got the air out

It's got a 4/5 race cam

 

Early merc injector torque spec is double the later models, I was cautious and went for the lower spec but looks like the injectors are leaking a bit of compression so will pull everything apart and re torque them and try again
