When you say standard injector or junior timer connector could you possibly expand a little for the uninitiated? Cheers

The damage has occurred to one of the brass inserts.

I was just thinking about doing that! Should have done it before. Cheers, Del

I am an expat living in La Paz, Bolivia, and I have a 1999 3.5 V8 Defender 110 Station Wagon. About 10 years ago I installed a Megajolt system from Trigger-Wheels and it has worked without any problems and I am very happy with it. Unfortunately last week when a mechanic was changing the suction hose to the power steering pump some damage was done to the plug connecting the shielded cable to the sensor meaning that I have to source a new plug. One of the ways I could do this is to contact Trigger- Wheels and source one from them but the thought of having to shell out around 25 pounds in courier charges for something probably costing around a fiver is making me a bit reluctant to choose this option. From the research that I have done I understand that the position sensor used by Trigger-Wheels is sourced from a Ford Focus. If somebody could confirm this or give a different answer I would be obliged. There are numerous parts suppliers in La Paz and with the old plug as a sample together with some basic information on the vehicle it was originally sourced from I am fairly confident that I will be able to find a replacement.

Thanks for that! I had been toying with the idea of of installing a Megasquirt system which now no longer seems to be a "nice to have" but essential. Pity about your flywheel as well. Cheers, Delwyn

Gentlemen, many thanks for the replies! One less thing to worry about. Delwyn

I am giving some thought to swapping out the 3.5 V8 in my 1999 Defender 110 with a 4.6 V8 from a 2003 Disco 2 which I know is available. One of the most obvious initial problems is that the Disco motor is from an automatic. Is it possible to swap the flywheel across from the 3.5? Cheers, Delwyn

I have an Engine Guard system installed with senders on both cylinder heads so I am not too worried about getting caught out with overheating. What I would like to do is get the installed temperature gauge working as it should. I am probably being a bit obsessive but it really bugs me. Del

That is what I was hoping as well but when I spoke with my usual UK supplier, MM 4x4, a while ago they told me that the thread is difference so a non-starter. Thanks for the suggestion anyway. I bought the truck in 2010 when it had just under 50,000 miles on the clock and I have put another 40.000 on it so it is just about run in! As requested I have attached a photo (hopefully). Cheers, Del

My vehicle was a special build imported into Bolivia for the United States Drug Enforcement Agency and is a 3.5 with SU carbs. The part number I obtained from the LR parts manual for VIN XA159807 on. Del

I am located in Bolivia and have a 1999 Defender 110 with a factory fitted 3.5 v8. I have been trying to source a replacement water temperature sender part no. YCB100400 without any luck. I thought I would try this forum for suggestions as to a possible source or maybe an alternative. Any suggestions are welcome. Cheers, Del

Thanks for the reply. You have summarised my thinking. I have checked and cleaned the sensor spade and the connection. The prospect of checking the sender wire does not fill me with joy but I will have to do it. As far as the sender unit is concerned I would have thought it would be either working or not working but I am only guessing, do you have any thoughts?

I run a 1999 V8 Defender 110 Station Wagon and recently the temperature gauge has started playing up. Occasionally after getting up to operating temperature, and sometimes during warming up, the temperature gauge needle will fall back to approximately half way from the start position to the running position over a period of a couple of seconds. Then after about ten to fifteen seconds it will go back to its previous position. This fault occurs intermittently. I have an Engineguard fitted with temperature sensors on both cylinder heads and this is not displaying any change in temperature. I have bled the cooling system and checked the electrical connection to the temperature sensor. Any suggestions about possible causes welcomed!

I finally got around to installing the Piper 270 camshaft last month and I have been very pleased with it. A couple of weeks ago we went to a place about 110 km. from La Paz that we go to reasonably often located at 1,500 metres a.s.l. and on the return trip the truck was able to hold third gear for most of the way on the long climbs. As this was the main reason for the camshaft change I am more than happy. The performance on the flat has been noticeably improved as well. Cheers, Del

Gentlemen, thank you for the input! Del

Out of interest what sealant did you use? Del

I am finally getting around to my planned cam change on my '99 3.5 V8 Defender 110 Station Wagon and I am in the process of sorting out the various steps. One of the areas I would appreciate input on is the installation of the new valley gasket. The replacement I have is the later type and I haven't been able to find any clear recommendation regarding the need for additional sealant during fitting other than the occasional recommendation to use blue Hylomar around the water passages. Any recommendations will be gratefully received! Cheers, Del

Even diesels require their fair share of oxygen and suffer from the same power reduction problem. I have ordered up a 270 and the various bits and pieces necessary to install it which should all be here by the end of next week. When I have got it installed and tried out I will report back, hopefully positively! Cheers, Del

You are not wrong!! 😕

The mid rev range of 2,500 to 3,500 rpm roughly equates to 30 to 40 mph in third which is where I am getting grief. The engine is on SUs and I have a lambda sensor and gauge installed which I use to reset the carbs when the elevation changes by around 3,500 feet

For my off road needs the standard cam provides adequate performance. Where it lets me down is on the tarmac. As you can appreciate in the part of the world where I live you can spend a lot of time either going up or down hills with a change in elevation of 7,000 ft. in a 60 mile drive not being uncommon. The most common gradients I encounter at altitude just prevents being able to hold third gear at around 35-40 mph. This results in a lot of the time being spent thrashing the truck in second followed by a brief spell in third before having to change back to second. The cause of the problem is the drop off in power with altitude due to the reduction in the oxygen in the air, in La Paz there is only around 65% of the amount at sea level. For that reason I picked the 270 to, hopefully, get a bit more power in the 2,500-3,500 rpm range. Del

Thank you for that confirmation. As far as the camshaft goes I have decided to go with a Piper 270 from RPi.

I had fitted a new distributor abut a year prior to the Megajolt installation but it still made a significant difference. Del

I installed the Megajolt ignition system back in 2012 and it has been one of the best changes I have made to the old truck! It took a little while to get the ignition map sorted out but it is now working like a charm. Del

I have attached a couple of photos of the oil filter cartridge mounting which looks to be the pre suffix B straight gear type:- Any feed back appreciated. Del
