Or an oxygen sensor - if your engine/ exhaust uses one
Exactly as Phil and Scott have suggested above ^^^
First step, is to see if you have an O2 sensor connected in the exhaust, and if so, simply disconnect it, and see if there’s an instant improvement.
If no O2 sensor in your exhaust system, then replace the Temp 2 sensor in the thermostat housing. Cheap, and easy to do.
Yes I have an oxygen sensor in the cat ( cat is hollow, no element inside)
I don't understand o2 sensors real well. I thought if I disconnect the sensor the ecu then puts the engine into open loop mode making the mixture richer, wouldn't I smell more fuel not less?
I disconnected the 02 sensor, doesn't seem a real obvious difference , smells still rich but agreed I don't see as much black smoke.
However regardless of the sensor I have now got Borat to run nicely even when cold.
I have ordered new temp sensors and a new o2 sensor .
I did check the resistance of the temp sender and gauge sender. The both had resistance but I didn't look to see if it was within tolerance.
Then again I don't know how they really fail . Is it open circuit? Short circuit? Or just higher or lower resistance?
There are 2 sensors in the thermostat housing.
One is just for the gauge but the other (Temp 2) is the one that goes to the ECU.
It is one the front of the tower (I think) and not the side.
All of the above
Thx for the reply. I ordered both sensors,
Col had helped me with a cat with an element in it.
So after all this we will see how it runs.
Perhaps I should just do a compression check, i guess if I have low compression that can explain some blue smoke.
A good burn out will probably help.
Engines that sit for ages and have been twisted all different ways prior to installation often blow a bit of smoke before they come good...
Ok that is good to hear
My SC has been parked up since early August. It will need a “wake up” run, to get it back to normal...
Borat Progresses but Nearly as slow as Brexit
On the weekend I finally got Borat off the car ramps. It made my wife happy as she has complained our place was resembling the car scene in the castle.
Darryl Kerrigan: “Oh Steve, could you move the Camira? I need to get the Torana out so I can get to the Commodore.” Steve Kerrigan: “I'll have to get the keys to the Cortina if I'm gonna move that Camira.”
With a new o2 sensor installed and Cols cat converter all tightened the motor now sounds real pretty. No oil leaks, no coolant leaks. The 2nd hand alternator is working too!
I noticed the dash alt light always goes out with just a touch on the pedal. Is this normal for T3s or just peculiar to this alternator?
Next steps before roadworthy- fix the broken pop top struts. This is a trakka
Fix the fuel gauge, inspect the brakes. There is rust down below where the fridge is, need to remove it and then assess the situation.
I guess you can tell I am a little bit happy with the progress. Who was it on that TV show that said " I love it when a plan comes together"
Mine does that on occasion too.
My 69 kombi does that and it charges well - but seems to need a rev to equalise the voltage so the light goes out.
Great work on getting it rolling again - love seeing another T 3 on the road.
The petrol tank job really sucks - try only doing it on a near empty tank.
Not really sure how much fuel is in there but now Borat is face up in the air on ramps. So a lot of room to work under there, I will use a small hydraulic Jack to help with the lowering.
Floppy main headlights
Just noticed the top plastic adjuster on each headlight has broken.
I think it is the lateral one. Do I need to take out the metal frame as well as the headlight to replace the adjusters ?
Def easier. To fit the new adjuster, you’ll need a screwdriver and a hammer. Line up the adjuster to the hole, place screwdriver in the head, and give it a very firm tap with the hammer, to seat the adjuster in the hole.
This is much easier done on a flat surface, with the surrounding areas of the frame, well supported.
Thx Grant, I will get in to it
Unfortunately J41783 and 31153 are on back order
