Re: A materials question

Very unlikely that there is any asbestos there. As far as I know, the filler used on fibreglass mouldings etc is a resin substance, possibly also with an inert powder added, and mixed with a chemical hardener . When cured, if it is sanded it produces white powder

Re: Basic questions when buying an E Type. Question 1

I really would not worry about the views of Mr SR Jenkins , Jaguar Engine Development. Almost 30 years have passed since he wrote that, and no-one so far as I know has ever paid any attention to his advice, and yet the engines including quite a number of 60 to 70 year old ones are still running perf...

Re: sticky engine valve

Sticking valve is not the first thing I would think of, because it usually produces symptoms of banging in the exhaust etc, or backfiring through the carbs . A burnt valve is a more likely candidate, which a compression test will reveal . If you suspect gumming, then redex in the petrol, and trickli...

Re: Windscreen scratches

I have never seen marks like that before , and particularly in the third photo down they look both deep and wide . I doubt very much that they can be polished out even with a cerium oxide powder, and if you attempted that the likelihood is that the visual quality would be impaired. A visit to Autogl...

Re: Engine Oils, a question for the PetroChemists amongst us

IMHO Not really ok, no. The oil itself probably won't have deteriorated in lubricating quality , but its detergent properties / function will have been lost, and what you risk is that the engine may become gummy with that brown gum that can develop

Re: 4.2 starter motor wiring

No, the "ignition warning light " switch is a separate switch - rather like the brake light switch to look at, but with a single terminal rather than two, and it is usually to be found a few cms in front of the oil filter, just to the rear of the right hand front engine mounting I am trying to post ...

Re: 4.2 starter motor wiring

Pierre : the black and brown lead goes to a single blade, oil pressure activated, switch which is screwed into the oil gallery which runs along the right hand side of the block at the level of the oil filter housing. It is an oddity of the "ignition warning light" on early 4.2 litre E types that it ...

Re: Rev Counter

I've returned rather late to this , but I think the 6500 tacho is possibly from an early 2.8 litre XJ6 which certainly had chrome bezels. I cannot think of any other candidate - the 2.5 Daimler 0 - 6500 was of course 8 cylinders

Re: Speedometer on S1 4.2 OTS

Ah ! if yours is a 1968 USA spec car, then the likely axle is 3.54 which will have the 46/13 tag on it . The probable original speedo for this is SN 6322/37 and at a guess the turns per mile would be 1312 or something very close to that

Re: Rev Counter misreading

David : this tacho is over-reading not under-reading so poor magnetic flux is unlikely to be the problem. I suspect that with this being a 1968 car it may have the electronic ignition driven tacho . These are notorious for a. misreading where electronic ignition has been fitted as her, and b. having...

Re: Define the spacer into the hub

Pre-loading the hub bearings is directly contrary to Jaguar's specification and is bound to increase the heat produced in the bearing .

Re: Speedometer on S1 4.2 OTS

It sounds to me as though either the trip odometer or the main odometer has been changed for one from a different speedometer. Each odometer has an independent gear set, and ones for mph and kph use different ratios, as do various speedos for different axle ratios. I very much doubt that your car ha...

Crikey !! In 60 years of playing with engines I have never seen anything like that . There has to be a reason, but at present I have nothing to suggest except possibly gross over-revving leading to valve bounce. What do the relevant pistons look like ?
