Rm8k Wira & Jazz GK5 ownership experience-A long way to go

[parakey]

Believe me MMC has it's own set of problems. MMC is also more "dumber" so needs a lot more input from you to make it work. Then there's the dreaded throttle body screw....... hahahaha

Tbh, I dont see how VDO is smarter when all it's sensors left, right and center breaks down so often

 

[KHNG940413]

You should find out what happened to the second sensor to cause it to die. Sounds like short or physical damage if you ask me. If it's a short then GG..... if it's physical damage you going off-road a lot ah?

My working environment is quite....bad
Construction site as you can think.
Got dust,sand,mud,water pond
Gravel road,cement road, half half off road to be honest. Hahahahahahhaa

swap to MMC 4G92 DOHC. hahahaha

Actually my friend wanna sell his 4g92 sohc engine.
But juz engine only abit susah.
And also the crank need to adjust something.

Any sifu know is there anywhere selling those wira bottom engine cover? Like thise conti car have at their bottom of car one.

Very2 long time ago when my hair are all still black, there is one company whom makes and sell this.Its a local brand. However i dont recall the name brand or if they are still around. Maybe other member with more white hair than me can shed sone light.

Why would you want that? U cant see leaks. Accessibility harder also

After changing my cam & crank sensor the 2nd time this year. I was thinking is it because my working area those stone,sand,mud thing cause this.

If yes,if I install this will it extend the life span of my cam & crank sensor and other part.

Juz my thinking only lah

Was the sensor that dirty?

 

[KHNG940413]

Abit dirty at the sensor side bottom. Although After cleaning still cannot use la~
My car always running at those sand rock road. Alot of sand going inside the engine bay.

 

[KHNG940413]

What I saw on FB is like this.

 

[parakey]

If you close the bottom, where's all the heat that the engine produces going to?

 

[KHNG940413]

If you see closely the pic,they have a vent in & out.
But not sure can it really ventilate the heat out.

Should not be an issue. My old pajero comes with a metal sump guard.
Then again the engine bay is very spacious.

Is your wira lowered ?

what crank adjustment? haha. buy complete with wiring, ac and power steering system. easy to swap if complete.

search for orsen shield. price online should be around RM300++. this one from zhapalang selling at RM310

Wira update.

After changing both cam & crank sensor the car start nicely and didn't mati agn until...... Today.....

Lucky the car can start back without taking the battery wire off. Juz turn the key few time and it start back agn.

After makan breakfast I went back to the workshop,the boss see my car also kepala pening. He unplug all the wire on the ecu and wait for his checking result....

Like bro. Izso mentioned something might be shorting the sensor........

The mechanic had check all my sensor. Everything is running fine.
Today morning it juz suddenly went dead agn. Starting to getting piss by the vdo thingy. Although is nice to use but when it got problem is really haed to know which thing break down. Diagnose also didn't come out any code is quite difficult.

Check your wiring for the sensors leading back to the ecu. If it aint the wiring, it has to be the ecu. Sensors relay information back to the ecu. It's the ecu that makes the decisions.

They had unplug all the socket and wait for an hour(dunno why) and connet them back. I let it idling 30minute while aircond open and it didn't went dead.

Now I am like driving a time bomb. Dunno when the car will went dead again. Hahahahahahaha

He He . .sounds like that's the limit of their diagnostic skills. Unplug, wait a long time, replug

If possible just borrow 2 grounding cable and install at engine block and firewall back to battery.

I am thinking its bad grounding. Different driving situation will have different current+grounding demand. During idle, a bad grounding wont pose much problem...on cars laden with electronics, revving the engine with bad grounding will show multiple error code.

With regards to bad grounding, wont that show up more during starting when a large current is drawn? If grounding to engine was suspect, it cant possibly pass through enough amperage to start.

Not totally ruling out grounding. If ecu has bad ground to chassis, then it may cause issues. But that's related to chassis ground and not the engine side

yup it should show up during starting.
since the car is driven over rough surface and wiring is old, possible shaking+ratting damaged of loosen some crimping and caused oxidation.
