haha good work ... now how the hell do i find what i'm lookin for

lookin for the injector pump set up n turbo stuff for td42t

Post by **sw1** » Fri Jul 18, 2008 1:21 pm

fyi: you have td42ti
use the main part of the manual as normal
then consult the supplement. as for which supplement, use the last supp before your year patrol. ie. i have a 2003 patrol so i use the last supp from 2002.

its a pain in the a$$ but the gu manual refers to the gq manual for the td42 injection pump. i got a hard copy of the gq pump section, which has all the info
the td42ti pump has a timing advance mechanism which isnt covered anywhere, that ive seen.....

anyone have acess to info on the td42ti pump??

btw: nice pick up with the 07

do yourself a favour & block the egr!!

relooking at your phots why is there one nissan oil filter & one ryco oil filter??

i'd be dropping the oil and filters and fixing that.

not my ute its a mates that i'm building up ... so much new stuff on these motors

whats the EGR?

Post by **sw1** » Fri Jul 18, 2008 6:57 pm

exhaust gas recirculation

basically feeding what comes out your bum into your mouth

the rusty colored thing in the third photo is the solenoid that opens & closes.
where it bolts on to the intake manifold undo the bolts, pull the gasket & make a blanking plate. then put the gasket & blanking plate back in the spot where the gasket was.

what does removing it affect?

how do i go about adjusting fuel on the injector pump
same as the old TD42s?

Post by **sw1** » Sat Jul 19, 2008 8:01 am

theres post upon post about this at patrol4x4.com
basically when exhaust gases get recirculated they mix with oil vapor from the crank case and they from a thick black abrasive sludge in the intake, as this sludge get dragged thru the motor it ultimately reduces its life

i had my 2007 pump replaced with teh one from my old 1999 engine as the new pumps have a electronic control thingy which they said was not as easy to mod for high HP.

also no. 1 injector has electronic control as part of teh imobilisor.

Thats as far as my knowledge goes on high tech deisels

i agree with sw1, depending on how far you have gone with the pump, turbo etc its benificial to remove the actutor and butterfly valve in photo 2 to reduce air restriction, then i cut out the plate between the EGR port and the charge air port in the inlet man and welded shut the EGR gallery (under the cast elbow). This has increased the airflow cap by about 20% to match a 75mm custom intake flange and elbow from charge air cooler.
The boys at leading edge head specialists have done a few like this to match the ported head\extractors I have.
Still putting it together so will see how much the power and egts are improved soon.

Aside from that the TD42T im biulding also has that plug ontop of the pump like in photo 1. what does it do?? the pump on my normally asspirated/manual gq dosent have it.....

the only etxra 'electric thingy' on the pump is a solenoid that can advance the timing.
how is that detrimental to big hp??? , unless it takes upon space that is otherwise needed?

the sensor on top of the pump is throttle position sensor. i believe auto gq's have them as well.

Post by **garth** » Sat Jul 19, 2008 12:16 pm

a throttle position sensor, ok makes sense...the engine came out of an auto so im guessing its something to do with that? shouldnt need it for man?

My 92 manual GQ had the sensor on it, kept playing up so I kept it unplgged

Post by **Hoonz** » Sat Jul 19, 2008 3:57 pm

my 95 GQ didn't have one ....

Post by **garth** » Sun Jul 20, 2008 8:56 pm

so what does the sensor actualy control?, is it the pump advance or something for the auto trans?
Its on a auto 95 too...........

The sensor/its actually a pot or variable resistor on top of the pump is for EGR control.

The one that is at the bottom rear of the pump is the TCV or timing control valve.

ok thanks matt, i have removed all the EGR off the engine, is the plug ok to be left disconected or are there plug pins to bridge?

The pump i have does not have the elec advance (1995 24V safari model) when did they start putting that on?

Around 2003 i think mate, what plug have you disconnected if its the EGR one then that fine.

if you block off the egr disable the egr butterffly in the intake.

the pic of the butterfly accuator (2nd pic) is a little different to most i've seen. check where both the vac tubes go to.

The second picture is a smooth shutdown butterfly to reduce cylinder pulsing it has nothing to do with EGR.

If you look in the factory manual it shows it as working with the egr system

Also when you shut the thing down it doesn't move

Ok ill have to check on that,dont see why it would have anything to do with the EGR but ill have a loook at it.

My view is that the flap is there to provide a pressure drop at cruise so that egr gases will enter the ducting. It may also service as a stopping aid.
