I received the timing valve in the post and of course I head outside to install it to the injection pump. I could complete the build up in a fraction of the time which took me to dismantle everything. I got a bit worried when I could not start the engine strait away. In fact it took me about 20 minutes to start the motor. The injection pump and pipes have been empty and it took some time to get everything running. I have used the little hand pump on the filter to push the fuel in to the injection pump, but I’m not sure if this has made a difference.
I took the Land cruiser for a test run and after the engine warm up, it run perfectly. All what I have to do now is to put the bracket clamps on to the fuel line and the 2 covers for the injection pump.
If anyone ever experience the same problem on the Land Cruiser 100 with the HD-FTE engine and the injection pump 22100-1C170 the suction valve or the proper name Valve Assy, Timing number is 09630-0580 from Denso. This valve can not be ordered via Toyota or Denso. It has to be 3rd party supplier and I could not get it from Partsouq or Amayama in the UAE.
Can someone spot the mistake what I have made with the assembly?
As I’m still waiting for the new Timing Control Valve, which will be delivered soon, I got time left to do other tasks which I have pushed out far to long. One of those is to check and adjust the valves on the engine. The cylinder head cover No.1 and No. 2 are off and the access is very good.
On the outside of the intake manifold I have noticed a carbon deposits build up and as it is everything stripped down I changed the gaskets and also cleaned everything up, so good as it gets. I did not bother clean the inlet ports on the head as I don’t want anything going down to the valve seats. On the end I would have to take the cylinder head of to cleaned out. No way.
As I have mentioned on my previous post I noticed a small leak on the injection pump. Not a lot, but enough so I have to fix the problem. I checked the pump and noticed the plug for the Timing Control Valve was soaked in fuel and when the engine is running a trop of fuel came out every 10 seconds or so.
As it is always, the access to the valve is very bad as it is located on the bottom of the pump. The only way to remove the valve is to dismantle the injector lines, brackets and pump stay.
It took me a long time to remove everything. Some people say it can be done without removing the injector lines but I could not get on to the rear bolts of the pump stay while the lines are in place.
This is the timing control valve or suction control valve which is a DENSO part. The problem is, the fuel is leaking through the plastic connector which cannot be repaired. Unfortunately Toyota will or can not sell this part. They would rather sell me a new injection pump for an astronomical prize. I could source this valve from a specialist company but it will take some time to get it.
After all the repairs and modifications of which I have recently done, I wanted to give the Land Cruiser a good test drive to see how he behaved. We took the LC to a mild Greenlaning session in Northumberland with the stunning views and ideal routes.
Great to take advantage of the weather as the routes won’t be this dry and green for much longer this year.
Diane really enjoyed her drive in the LC.
Even the Highland Cows are interested to see the Land cruiser and Diane or are they just being nosey?
I’m still waiting for the tank protector to arrive. I have now plenty time to continue on the fuel tank. I removed all hoses and covers and have taken the sender unit out. I would aspect much more dirt on the strainer. Even the internal of the tank was pretty clean.
On the next step I have spent a number of hours to clean the outside of the tank from rust. Then I sprayed a couple of layers Dinitrol RC900 rust converter on.
I had a good opportunity to install the balance pipe which is required for the auxiliary Front runner tank which I planned to install very soon. Also I have installed all the fittings for the tank and a new strainer for the pick-up pipe.
After a couple of days to let the rust converter work in to the metal I have painted the outside of the tank with chassis lack a couple of times.
At last I have sprayed Dinitrol 3125 HS over the paint which is a corrosion prevention fluid with has an excellent film building properties on open surfaces and leaves a brown,waxy,water repellent film. This, I hope, prevent any further corrosion.
Since about 3 years I’m planning to remove my diesel tank on the Land Cruiser 100 but never came around to do it. There was always something else more important. Now when I have taken the fuel tank out I’m glad it is done and I hope it was not too late. I’m surprised the tank is not leaking as the condition is not good.
The under tray or tank protector is so brittle it just has fallen appart when I have removed it. Definitely have to order a new one and new tank straps as well. Now I have to look where I get all the replacement parts.
The other day when I had my head under the LC I noticed the left hand spring was broken. Last year I installed new Pedders shock absorbers but never bothered to change the springs as well. The Pedders shocks are heavy duty but I’m not sure if this had anything to do with the broken spring. It seems to me not so long ago when I have installed the Old Man Emu springs but after I have checked the mileage on it, I discovered it was more then 50 000 miles. So they have not performed as badly as the LC is very often heavy laden and used offroad a lot.
It did not took very long for a new set of Pedders (7845) extra heavy duty springs to arrive and with a pair of Urethane 20mm Coil Spring Insulator which fit perfectly to it.
The Pedders springs are slightly higher than the OME’s and definitely stiffer but the diameter of the coil is still the same.
It took a bit an effort to install the new springs as they not compress very well but eventually I have succeeded. Pedders claim this springs are suited for constantly loaded vehicles but I plan to install an auxiliary tank in the near future, this is not an issue for me as Io will have plenty extra weight on the rear axle.
I hope the pedders coil springs perform so well as the OME’s. Only time will tell.
