Re: JD40 Sprocket Retaining Tool

Not having the JD40 tool or easy access to them here in Africa, I have used normal washers with a hole just larger than the spigot on the sprocket centre and thin enough to slide into the groove. As backup, I drilled a small hole through the washer's rim and attached thin wire to it with the other e...

Re: Overdrive S3

wheelspin depends on torque and diff ratio. It also depends - very much - on flywheel mass (in case of a manual). I drove my previous S3 in two configurations (both fuel injected) : 1) low compression pre-HE with std (heavy) flywheel ; 2) 11:1 high compression HE with Fidanza light weight flywheel....

Re: newb wondering what it takes to fit a V12

What does it take to fit a V12 in an S1 FHC? Yep, you won't get much support for that idea among us on this forum. Why not get a S3 and rather spend your money on fitting a 5-sp transmission ? (this is the S3's biggest issue after a modern ignition system) I am the technical caretaker of a friend's...

Re: S1 (4.2) vs S3

for myself the 3.8 has always felt the more dynamic and racy.... I have owned quite a few Land Rover V8 engined vehicles, 3.9 Discovery 1, Discovery 2 4.0 (now converted to 4.6) and 4.6 Range Rover HSE. (I'll not mention my current 5.0L Supercharged Rangie....) The "sweetest" of them all was my sis...

Re: S1 (4.2) vs S3

going up a steep hill I put the autobox into 2 but then had to stop , started off again forgetting the trans was locked in 2 ( the same gear that was good for over 100 mph ) . No problem , it just pulled away as normal - I have (bad?) news for you Mark.... "2" on the transmission selector means : "...

Re: Webers or Fuel Injection

1. Don't do EFI. It is a long way, until it will work good. I agree. For the money and effort, rather do a 5-speed with overdrive 5th or in the very least a 2.88 diff. 3. I have 4 Stromberg on my 6,0L HE-Motor. they are working very good, the motor has a lot of power. I agree! The Strommies are exc...

Re: Hi Torque starter motor

I also agree that a reduction gear starter is one of the least urgent upgrades needed on the V12. The manual and auto also differ in teeth count BTW. Just because it SOUNDS like its turning slowly does not mean it is actually turning slowly. On my XJS as well as my EFI'ed V12 e-type I could see the ...

Re: S1 (4.2) vs S3

Well, I find the 4.2 a VERY INTERESTING engine!! (I would say even more interesting than the V12....). It certainly sets a few records in MY book: 1) It is the lowest revving PETROL engine I have ever come across - pulling strong from below 500rpm but complaining from 4k rpm onwards. I have taken to...

I am the "technical manager" of my friend's S1 4.2. It has fallen upon me to take care of the car from a technical / maintenance perspective. When he approached me to do so, I had ONE condition: That the distributor be upgraded with a 123 Ignitions Bluetooth distributor - which I did first time I to...

Re: 4.2 Rear crank seal repair

I have a pit in my garage, so working under the car is no hassle. I cleaned around all three banjo bolts and then tightened them a smidge just for good measure, but they were rather tight already. There were signs of oiliness back against the head, but that could have come out the tach generator lon...

Re: 4.2 Rear crank seal repair

Thank you chaps! Its clear to me that a proper job on repairing that rear crank seal will require almost a full rebuild. Need to advise the owner accordingly.

4.2 Rear crank seal repair

Is it necessary to remove the head on a 4.2 when having to remove the crank in order to repair a rear crank seal that is leaking excessively? I am very familiar with the V12, but the 4.2 is new to me. From what I've seen it seems one has to remove the head to remove the front timing cover before you...

Re: 4.2 Suspicious sound

Note that it is best to equalise the tension on both sides of the chain which involves turning the engine backwards a little way after you have checked the tension on the exhaust side of the chain, and then readjusting to give similar tension on the inlet side Thanks for the tip!! Adjustment done. ...

Re: 4.2 Suspicious sound

Having removed the tappet cover, it seems there is a lot of play in the top cam chain. I can lift the chain away from the guide about 10mm (3/8").

I recon the first order of business it to do the procedure for tightening the top chain?

This car belongs to a friend of mine, but I’m the lucky fool who has to maintain it. Whilst waiting for the fan to come on, I realised that I hear a sound which I don’t like. Its audible all the time in the video but at 16 secs, I turn the phone’s mic towards the oil filler opening and then the susp...
