Re: S1 & 420G similarity

Steve : I don't think that this washer is in fact an authentic part. I see that this diagram is in fact from Terry's which is some American aftermarket spares outfit . If it's not in the Burlen list, then in my book it's not authentic !

Re: Series 1 3.8 low oil pressure after fresh engine build..Help!

Any leak on the suction side of the pump will cause a loss of both flow and pressure because the pump then compresses the air in preference to the incompressible oil . I doubt that you have done any damage by running it, but IMHO it is essential to change the rubber/neoprene seals for new ( and corr...

Re: S1 & 420G similarity

Peter : I don't think machining a taper on both inner and outer faces would work, as the studs would then be out of alignment, particularly on the carb end of the manifold which IIRC have longer studs. The E manifold, compared with that of the mark 10 / 420G , has a step down which lowers the carbs ...

Re: XJ6 versus E Type

The styling originally tried by Lyons was indeed redolent of the E, but the intention always was to create a luxury saloon of extreme refinement. As others have noted, there was nothing altered by BL, which in fact had virtually no input into Jaguar because Lyons took great pains to see that no one ...

Re: Long stud straight port head....or short?

Unless it is an artefact in the picture, the block in your photograph looks to have the vertical ribs adjacent to the core plugs which were only present in the S3 XJ6 block ( and some of the military engines ) . If those ribs are present , and not just a quirk of the photograph, then this is an engi...

Re: Long stud straight port head....or short?

I have now looked at the photographs of the block. This engine as a whole has nothing to do with an E type. It has the vertically ribbed block which came in with the Series 3 XJ6 and IIRC has engine numbers which have an 8 prefix

That looks to me from the top picture to be a later long stud type head, as it has the slight rearwards extension at the back of the head Your block , whichever it is, will be unmistakable.Short stud blocks have the studs solid within the block face. Long stud blocks in contrast have the stud coming...

Adrian : I advise strongly against using a blowtorch, because there is too much alloy in the vicinity. Use a hot air gun on a 300C ( or if you really must, 500C but be careful ! ) setting . Penetrating oil and/or an ATF/diesel mix are your friends , and you might try shock therapy by heating the yok...

Re: Engine paint Colour

Except for the very early cars , Gold was the standard head colour up until ( about ) the introduction of the S2, which I assume yours is, at which point the heads were left as natural aluminium . I have always thought the blocks were shiny black , and they certainly look nicer shiny rather than sat...

Re: Minimum thickness of the tappet

Michel : provided that the shim is still sitting above the valve spring cap there should be no problem. The only danger arises when the shim is so thin that the tappet is actually pressing on the valve spring cap rather than on the shim.( There is then a danger of releasing the collets ). I should u...

Re: 3.8 1962 gearbox cover colour?

Certainly both of mine were gloss black

Edit : I was referring to the gearbox cover itself i.e. the bit which is screwed to the tunnel. I now see you are talking about the tunnel cover - I really don't think it matters, but I would have thought that Jaguar in those days would have used gloss black

The DB5/6 , though nice to look at, as a driving experience is not a patch on an E type, feeling rather lumpen and lorry like in comparison .

Re: steam

If you have smelled coolant, then you have a leak. On the right side the most likely places are the manifold to head joint ( not very likely ) ; the water pump and/or manifold to radiator/header tank ; and most likely the heater to manifold connections

It may be possible to use the waterpump but it is a bit un...
