Tb42e

[Bloodyaussie]

I thought I would start a thread on just TB42e's and post links of other members threads of the same model as many of us dont actually post in the title what car we have..

Maybe start conversation in regards to the TB42e's

Maybe other could start one specific to there cars eg TD's... winnie , Benny, AB.... and so on

Try not to fill it full of banter there is a thread for that.

If there are any other members that had there own thread on this model please let me know and I will add it....

To set your tps correctly you need to put the probes from your multimeter into the plug as shown and adjust till you get the reading of 0.4v and then adjust your idle to suit... there is a flat head screw near the back of the inlet manifold

Excellent idea! Probably a good opportunity for people to put up some technical specs to help people with tuning and what not also. BA was it you that also serviced your fan clutch recently? If so how did it go? Mine is working like a champ now.

[Bloodyaussie]

Yes I did but have not fitted it... it is in the back as a spare.

The mod worked well.. maybe you should post up those picks you took.. I will see if I took some also.

[Parksy]

I never took any pics unfortunately, but this shows where I drilled into, tapped and used a couple of screws to hold the fluid in. I also used a strong epoxy resin called Hysol on the heads of the screw to stop any seepage. Used gravity and time to drain the old fluid(took ages) and also an air compressor to help blow it out. I had some 60k silicon fluid from my rc car lying around, and with a syringe was able to inject into the hub. Works much better.

you put the multimeter into what plug mate ?..the picture didn't come up .....I am assuming the plug that goes onto the tps ?..do you take it off the tps to do that ?

[Bloodyaussie]

I have fixed the photo showing where to check voltage on the tps... 0.4v and the higher you go the richer it gets. Mine was set to 0.49v and was too rich

Tb42e injector part number is JS21-1. Searching this on eBay can sometimes come up with brand new injectors(international seller) for very very cheap compared to the stock in Australia($200 per injector!!!). Autobarn and such ask even more (over $300 per injector!!!!!).
http://www.fuelinjector.citymaker.com/catalog/item/5426601/5376382.htm
The site listed above recondition these injectors in the US at $35 each and don't require exchange units. Postage is about 35-40 from memory so in total about $250 for 6 injectors completely reconditioned delivered to your door.
Very much worth it and I've used the guys listed above and my patrol returns great fuel economy despite being a petrol patrol...

Fuel rail pressure should be 40psi. Measure after fuel filter with an inline gauge. When the key is switched to ignition the fuel pump will run for about 5 seconds then switch off. The fuel pressure should rise to 40psi rapidly not slowly. The fuel pump will turn back on once it receives an ignition signal(engine started).
If the gauge rises slowly or doesn't reach 40 psi, chances are the pump is on its way out and will need replacing. Hard starting and bad performance can result from low fuel pressure.

[billyj]

if...sorry when you break your left hand side engine mount the superior eng control arm bush type mounts are not only cheaper than genuine rubbers but they are quicker to fit and bugger all extra vibes in the big petrol. you will find that the clutch gives alot more of a direct feel with the engine box held alot more securely.

also seriously consider an ecu talk works with the tb42e ecu and very handy being able to see the readouts

Patrols equipped with the "tow pack" option were equipped with water cooled oil coolers.

If the cooler isn't fitted then it's just a plate fitted. Sometimes they leak coolant (regularly) and according to nissan there is no gasket, it's just sealant. Not a hard job to fix, just requires the coolant to be drained before removing the plate/cooler.

[billyj]

tip #2 if you want dual batteries with a tb42e patrol use the piranha tray to suit a 2.8 diesel, you will have to move the vacuum canister and coil but this lets you get a full size 12" battery in the back corner of the engine bay.

tip#3 when you inevitably blow a head/head gasket have a very close look at the head/block to see if the rear most cooling ports behind no6 are corroded, its common for these to corrode resulting in insufficient sealing in this area and repeated failure, solution is to weld/epoxy the ports in the head and epoxy the ports in the block sealing them off completely, this prevents and further failure in the area and does not result in running any hotter

Mine is fitted with that cooler and have had it leak and fixed by George... pain in the butt spot to get to but not rocket science.

On that note I never realised it was a tow pack option... wow I learnt something new today!!!

[Parksy]

Can't remember where I learnt it, might have been from nissan themselves when I sourced new o-rings for the cooler...

[Alitis007]

Base timing is meant to be set to 10* BTDC but with age and the use of higher octane fuel you can advance it to 15 - 20*BTDC for a slight improvement in performance

[Bloodyaussie]

This is a brilliant mod for us E drivers as I fitted a third battery because the small battery is just not enough to power all my camping needs.

And George forgot to mention when setting the timing to 15-20 degrees that if it starts pinging to back it off... some may not be aware of pinging and set it to max and cause some serious damage.

Well today I got my car put on the dyno and it was putting out a healthy 80kw but is running very very lean.... apparently the fuel pump has had it (not even 2 years old).

George wants me to test the Fuel regulator also and asked if I could borrow one.

Will post up how this pans out?

[billyj]

id agree with pump my 2 year old pump was found to be dying earlier this year when i had my turbo kit tuned

Here is a good one for you all..

Tb42e fuel pressure regulator from bursons........ $335.

For that little pissy thing ???

You can buy aftermarket 52mm pumps for about $135 but i've seen them fail after 1 month lol

now next question I checked the tps voltage as best I could and got a reading of .37 what should I do now and also thanks for tip on my broken n/s engine e mount I will order 1 next week when I order some coil tower braces for the gu. Thats about spec, you could richen it up by turning it to get a higher volt reading but subsequently increase fuel consumption because the ecu will not switch back to the idle circuit but rather remain in the load circuit affecting base idle rpm which changes the base timing. You could try increasing the voltage and test driving it to find the sweet spot that you feel that is giving you more performance and adjust the rpm to suit

how would increase the voltage and its the Nissan Samsung plug I have to have yes

[Alitis007]

richen it up by turning it to get a higher volt reading t
how would increase the voltage There are 2x screws that 7mm heads on them that can take a phillips screw driver aswell. Loosen them off and rotate it clockwise or counterclockwise and watch for the voltage change on your multimeter

[Bloodyaussie]

Top and bottom screws and make very small adjustments to get the volt reading you want....

so from this on another page the coolant temp sensor is faulty my tacho is wrong running lean so ill change these

[kevin07]

new tip that I came across my tb42e was an absolute pig to start so I changed the oil put 1.5 bottles of lifter free and after 100klms all the rocker noise has ceased and the car starts immediately everytime im stoked next service this will be going in the gu

[Bloodyaussie]

Wondering what other E owners are getting in mileage out of there petrol tanks.. NOT GAS.

Since replacing my pump I seem to be chewing through petrol.. the last tank of 95lts I managed 320km and that was being gentle.

This tank seems to be much worse?? I finally got ECUtalk to work and a lot of it I dont understand but one reading on the o2 sensor which I know should be about .45v sits about.9v all the time.

Interested to see how many kms other E owners are getting??

[kevin07]

im around the 21 to 22 per hundred but I can feel the car has a good miss in it while driving ill change the coolant temp sensor first and then ill be looking at the injectors after that and at I guess I don't think it has a thermostat so ive purchased one as well.

[billyj]

.9 all the time could be stuffed, o2 should fluctuate between 0 and .9v while your driving not moving indicates a possible stuffed sensor

pull the spark plugs and inspect them all closely, in particular look at no6 for any signs of coolant(green/yellow/brown stains and lack of carbon compared to other cylinders) its common for the head gasket to fail between no6 and the cooling gallery at the rear of the block and a slight miss was one of the symptoms last time mine started to go, wasnt using any water either. im not saying yours has gone but worth checking the plugs

[Alitis007]

Leads, plugs, rotor button, distributor cap, low fuel pressure, blocked injectors, broken inlet manifold gaskets that are sucking air and sometimes ecu or faulty electronic components can cause a miss.

Start with finding which cylinder is missing by disconnecting 1 lead at a time to see if the motor misses more or stays they same. Disconnect and refit each lead while the motor is off so you don't get a 40,000+V shock lol it tickles a bit haha

So do you think fitting a turbo has helped???

[billyj]

the turbo has definetly helped the motor has so much more torque eveywhere and while im not making massive power(only 100kw at the rears on 33"s) the power come earlier and is much more useable. but at 6k so far (turbo kit, nistune board, fuel pump, injectors and dyno tuning) its not really a cheap way to chase economy)

another intresting note is ive discovered that towing my 2t tandem tradesmans trailer is no worse for economy than having a roof top tent fitted there is that much extra drag from the damn tent.

i dont have any no tent no trailer economy figures yet as i havent done any significant km's yet with just the patrol since fitting the turbo

[jff45]

.9 all the time could be stuffed, o2 should fluctuate between 0 and .9v while your driving not moving indicates a possible stuffed sensor

.9v is telling you that the engine is running in open loop or it is simply too rich for the ECU to correct.

A bad O2 sensor usually sits around .3v from memory with very little or no fluctuation.

A wideband sensor with gauge is a really good investment. Combined with an Ecutalk you get a pretty good idea of what your engine is doing.

[Bloodyaussie]

I will go for a run and video the results and post them...

Andrew I have no idea what that foam thing is for... I thought it caught moisture before it could get sucked into the engine?????

[Alitis007]

I think that acts as a noise baffle but it could be something to do with making the air swirl

[Parksy]

Cheers guys. Makes sense that it could be any of those things...

BA, does your o2 readings still stay on 0.9v after you replaced the dodgy injector?

[Bloodyaussie]

Here is the short video of my o2 readings... Erica's camera work is crap...fail.

Top right dial is o2


https://www.youtube.com/watch?v=I-3Dg3DayHQ&list=UUmqK0-SlGU8YG-ogcwfRYHQ

[jff45]

You can clearly see that the O2 goes to .9v when you accelerate.
At one point there it's at 2000 rpm, 3v MAF and 2v TPS and the O2 is at .9v.
At low revs/idle it's fluctuating as it should so it is working correctly.

I like to log my Ecutalk runs and create different graphs in Excel.. I find it's a better way to see what's happening.
