FT’s Patrol Project

[Flying Torquewrench]

Been busy with my normal work and the weather hasn't been great. So only done some small jobs on the car.

As shown earlier in the thread, I connected up the tail lights which are in the body. Personally I am happy with the result.

Let my friendly mechanic know that it is ready for the MOT. He will get back to me asap and it should either be this week or next week. Depending on when he has time and when I am not at work.

Not sure about the Patrol, but the Terrano has plastic sill/step protection covers on top of the sill. These are retained by a two part plastic screw and receptor mounted in the top of the sill, when removed leaves a few good sized holes for injecting your favourite anti corrosion muck.

My LWB Y61 has these, so assume the SWB will be the same. Great for spraying anti rust goo into the sills.

 

[Flying Torquewrench]

Yes, I had forgotten about those. Together with a long hose on the spraying can you can get nice into the sills.

Also is the rear overfender is installed with a screw that goes into the bottom of the sill. So if you remove that screw you can attack the sill from the front and rear.

MOT is planned for monday. Dropped the car off at the mechanic yesterday, he will give it a good once over before taking it for the MOT.

Fingers (and toes) crossed!

Good luck mate, you deserve an MOT and framed for your efforts :clap

 

[firebobby]

Ditto, it's been an epic journey so far, bet you can't wait to use it

Pop the door switches out too, they make good injection points also.

 

[Flying Torquewrench]

Thank you all for your kind words. :thumb2

I will keep the door switches in the back of my mind for when she returns.

However even if she passes the MOT that will not be the end of this project. I still have to repair all four wheel arches. They got a lot of rust on them and I would like to sort that out before it becomes to bad.

But that can wait till the weather gets better. Now I need the car asap as more snow is forecasted and we live on top of a hill. :doh

 

[Flying Torquewrench]

Some good news and some bad news after today's MOT.

First of all the car PASSED the MOT with not even a single advisory item!

Now the not so good news. Driving the car home I noticed some black smoke coming out of the exhaust when asking power from the engine. :hmh

Before syarting this project the engine ran smoothly with no visible smoke at all. During trouble shooting why the engine wouldn't start I removed the timing belt and as far as I am aware it was put back the same way as it came off.

I can do a bit of trouble shooting but in my engineering days I specialized in jet engines so I will need your help on this one.

Could it be that the fuel pump or the cam shaft is one tooth out? Help please :surrender

 

[Flying Torquewrench]

Additional info: The engine runs nice and smooth but it seems to be lacking some power.

 

[makeitfit]

I doubt it as it would be running rough as f$$k , if at all. Also your emmisions were obviously fine. So I reckon it's just a good boost of fuel . Did it go away once power was delivered?

 

[Flying Torquewrench]

As long as power is delivered it emits black smoke. Once i ease of on the throttle it stops.

It really surprised me as the emissions are fine. Also when giving it a good dose of throttlewhile stationary no smoke is visible. It is only when driving and i am asking power from the car.

I am hoping that it is not a Turbo problem. However i would expect that it would emit black smoke also when stationary if it was the Turbo.

Or am i wrong in my assumption?

 

[makeitfit]

Not an expert on this stuff sorry but as it's fly by wire I guess the ecu runs a diff map while stationary. Effectively the timinig the pump is changed a bit on the move and under peddle pressure
Didn't you have some pump issues or something way back ?
How many miles have you done since the rebuild?
Hope a boffin comes in soon, I'm spent now

 

[Flying Torquewrench]

I thought i had a pump problem but i turned out to be a connector problem. However in trying to locate the problem the timing belt was removed.

What i am thinking now is that maybe the fuel pump is one tooth out. But i don't want to take everything apart if it is something completely different. The car has done about 12 miles since rebuild.

Thank you makeotfit!

 

[makeitfit]

Well if you don't get the answer you need on here I know you'll get the exact answer and loads more in Aus.

Awesome site and all Patrols :naughty
I spend far too much time there :lol

Check the fuel temp and engine temp sensors, an incorrect output from either of these would result in overfueling. Note, the engine coolant sensor is normally NOT the one used for the temp gauge.

 

[Flying Torquewrench]

Thanks Makeitfit, will have a look.

Rayf3262, where is the fuel temp sensor located? And would this result in problems described? Ie, would this cause an over fuel when asking for power yet not over fueling when in neutral and giving it a good dose of gas?

Just out of interest. Could this be a sign of the turbo packing up? Its doesn't make any funny noises or anything unusual.

I am not familiar with the specifics of the engine/ecu layout on the Patrol, so I have no clue where it is located, but there will be one. The fuel temp. sensor however is normally in the IP.
Anyhow, the general principal of operation...
the ECU will detect input from the VSS (vehicle speed sensor) so when moving the fueling map applied will be very different from the fueling map applied when stationary.
The specific map applied is based on input from a number of sensors, the engine temp. and fuel temp. are two that can easily be overlooked.
If the ECU believes the engine is at low temp when in fact it is not then the selected map will introduce excess fuel, similar with the fuel temp, but to a lesser extent.
Given the disruption your vehicle wiring has seen, I'm just suggesting a couple of relevant, simple checks before digging too deep.

As a rule black smoke indicates too much fuel or not enough air, so is the turbo spooling when the coal is seen?

 

[Flying Torquewrench]

Rayf3262, thanks very much for your reply. I will try to find sensors today and will have a look.

The turbo spins freely and doesn't make any strange noises either.

Will update you later.

 

[Flying Torquewrench]

Found the problem and it could not have been any easier.

The intercooler outlet hose had slipped off the manifold, hence the engine not getting enough air. Hose installed and clamp tightened. Taken the car out for a spin and she is back to her usual self.

Once again, thank you all for your help.

The project continues when the weather gets a bit better and I will post pictures once again.
