P30 chassis drama , Optic sensor , (Australia)

[Gravel]

G`day all and merry christmas and happy new year ,
I have purchased a P30 chassis rv and the person i purchased it off told me that it had a new IP 12 months ago , It had the foot down no go syndrome so some mechanic did the optic bump but didnt mark the original position ,,, so I have a Tech 2 and can read the timing data i just dont know what the timing and fuel data should be any help ,,,
PS: the PMD has been relocated but as far as i can see there is no resistor in the conector ????????


Cheers all
Rob ( gravel man )
By the way its bloody hot here 44c today and for the next week ,,,, I love my air con ,,

we need to know OBD1 or 2. factory spec on the TDCO offset is IIRC -.35to-.75. as far as the optic bump the fuel rate at idle should around 7-8mm. You'll probably have to keep bouncing back and forth between timing and the optic bump as one seems to affect the other

Pics of that would be great as well, don't see many p30 RVs

so she is a side mount turbo , Im getting miss fire on cyl1 and 7 , the injectors are stuck open as the rv was sitting in the Australian outback for 6 years with out being ran , the owner passed away after ony driving the rv once ,
anyhow when i picked her up i drained the diesel and changed out the filters did the engine oil and trans fluid and filters , it has only 27000 miles from new , anyhow after the 3rd fill up on the way home i was getting a miss fire the rv came with a TECH 2 thats how i found the miss fire ,, so i have ordered new injectors they will be here today ( Fingers crossed ) ,, once i have fitted the new injectors i will try and check the optic sensor , Thanks again for the reply

OBD 2 sorry she is a 2002 year

Welcome. There is a lot of rip off injectors out there- where and what did you get?
Bad injectors can ruin a good 6.5.

model following AK’s lead, he’ll get you there.

The resistor goes in the pmd connector and if there isn’t one then you’ll need to put a resistor in the pmd. The computer checks the resistor every now and then. Since it sat for 6 years I bet the resistor is one of the first things the computer looked for and couldn’t find. This might also be one of the problems.

 

[ak diesel driver]

being OBD2 the resistor is supposed to only get checked doing a timeset/relearn.

 

[ak diesel driver]

Oh and just a warning max temp you want to see on a 6.5 is 210*

 

[Will L.]

The electronics on this engine are super sensitive to weak grounds. Sitting that long, remove them and clean the connections from the harness to the engine. A good practice to do it every 5 years, sooner if in rusty conditions.

Thanks Will , Im an Electronics Tech when i got home I cleaned all grounds , Thanks again

AK the 6.5 never went over 175 all the way home from Gillgandra to Nowra NSW about 10 hours driving ,, so looks good there that was with the air con running flat out the radiator is massive in this thing ,

 

[Gravel]

Will I ordered 8 new injectors the 2 that were coming up bad were cyl1 and cyl7 Both on MY passanger side ( Right hand drive ) so i will swap them out forst and bleed the lines and see what shows next

 

[Gravel]

I ordered a #5 and #9
What one should i start with ,,, I have a remote PMD so its easy to get to ,,,,
Cheers everyone ,,,,,

Will sorry buddy i brought Original GM injectors , we have a place here called suburban imports they get there enging parts from a company in the USA called gale banks ?? I have never heard of them but they have 24 months 50000 mile warenty so i thought they must be ok ,,, $650 US so near $900 Australian landed here .......

 

[ak diesel driver]

You won't be able to tell the difference between the resistors. The #9 puts out a tiny bit more fuel.

 

[Will L.]

Haha- electronics pro means those are the cleanest connections on any Rv in that hemisphere!

If it really is coming from Gale Banks and not someone scamming of his name, they will be good. Anything coming from Banks can be counted on, but is never low price tag.

Not breaking 175 : maybe verify that. It is really odd to stay that low. You definitely want to be above 165, I target 180. Most target 195 because that is peak for fuel efficiency, I prefer more “headroom” on the temp gauge away from too hot.

 

[ak diesel driver]

Unless Gale checks them they're just standard injectors you paid alot for. He is a big name in automotive performance.

I agree probably overpriced for what they are, but my thought is it really from banks they won’t be the cheap knock offs that put a hole in the piston after 30,000 miles.
