Re: Head removal tool

Reporting that this design, with nuts under the plate instead of threaded holes in the plate, is not suitable for preHE. Following photo, tappet block on the right is HE, flange has cut-outs above the head bolt locations that provide clearance for the nuts. On the left is my E-type tappet block, no ...

Re: Acrid smoke and low vacuum

Not yet, but I must be getting close ... https://i.postimg.cc/KYZvnr0J/20191110-215641.jpg The clatter returned (so wasn't just the air pump) and became continuous, no longer stopping when the engine had warmed up. Good reason to start the HE upgrade. I'm suspecting the acrid smoke was due to old va...

Re: XJ12 Engine

I believe HE's first appeared in 1979. It would be useful to understand why change was made, why the engine numbers don’t match? You have preHE heads and, according to my interpretation of engine no’s, a HE engine block. Less issues if I were wrong about this.To double-check the engine block, compar...

Re: Problem with horn on Moto Lita steering wheel

I assume "solder" means to braize using a gas torch. Alternatively drill and tap for a screw into the end of the rod that can be adjusted to length and held by a lock nut?

Re: XJ12 Engine

Nah, if not HE is not 11.5. And if carburetors not S3 either? Engine number, are you sure that the 1st numeral after the P is a 7?. What car is it in? If E-type, what is the engine number on the plate on the firewall? One explanation, if for some reason the e-type block had to be replaced, and all t...

Re: High Beam Headache

Seems to me you have proven that the problem is exactly as Ole predicted, broken pin/hole connections in this plug. Seems PO work around was to reroute the headlight supply from pin 2 or 3 to the centre pin 4 – via purple/yellow, red/yellow wires on the back of the socket. If this is correct u shoul...

Re: High Beam Headache

When headlights are on, side lights would also be on, so not much proved yet? The centre pin is #4? According to my wiring diag: 2 = high beam 3 = low beam 5 = side lamps 7 = RH flasher 8 = LH flasher The others don’t feature. The wiring diag suggests that the supply to the rear sidelights is from t...

Re: Engine stand reservations

Ok, thx, based on this I've just gone out and pulled a lot more of the load back onto the hoist (crank pulley) pending next step... I went for the highest and lowest bolts, incl. the starter motor bolt, so that the effective moment arm would be longest, so the tensile load on bolt holes would be the...

Thx peoples, in the end I used the two uppermost and two lowermost bell-housing bolt holes, I.e.: https://i.postimg.cc/dtqNSS35/20191030-115710.jpg My main concerns are about the stresses on the engine block bolt holes. The two lower holes will be in compression while the two upper holes (each 15 mm...

Re: XJ12 Engine

I suspect not. Yr engine, 7P76**LA, would be much later than '79. Later than mine (7P55**HB) which is '86. It is series 3 HE? HE engines, all the spark plugs angle inwards and are 16 mm. Pre-HE, the front 6 plugs angle forward, the rear 6 angle backwards and are 19 mm. High comp. is a defining chara...

Original did not have headlight relay. Pwr to the headlights AND the H/B indictor (blue) light is from the fuses after the dip switch. So it can't be the dip switch?

Re: Crankshaft Pulley

Hello Michel. My interpretation is that only an E-type pulley will work, part C32528. I don’t believe it was used on any other car, I interpret that all XJ12, XJS use the larger one, part C37892. Because of the oil filter pipe, only E-types have this (oil filter at the front). You may need to get a ...

Re: Crankshaft Pulley

Hello Michel. Paul’s HE XJ12 is probably same as mine (S3, 1886). It has the larger (15 cm dia.) pulleys that are all the same size, no use to you. What vintage is your XJS engine? I assume you have the earlier water pump and oil filter arrangement? On the E-type the steering pump belt runs through ...
