I got these covers with some parts can some one tell me what model they are off.

 

In the photo I see the thermostatic switch _ like mine. I have 340 and that switch was also used in the 3.8s.
Just sort of guessing here though.
Does it matter what they're off of, I thought that the covers were all the same for the 2.4, 3,4 and 3.8 litre models.
I know the later covers were not polished aluminum, but had ridges in them, painted black.
Later type, also found on the 340.


Sophomore Slumps: The Series 2 Jaguar E-Type ? Spannerhead


Edit :


Just had a look at mine and the nuts on the front of your covers are missing, Hmmm.
On the carburetor side of the block; what does the displacement say ?

 

hi jeff, its a 3.4, I was told it could be a early xk120 with out the bolts at the front of the cover.

 

Very early XK engines didn't have the front studs for the cam covers. However, Jaguar rapidly changed to additional securing studs at the front as the covers leaked like mad after only a short mileage, and owners complained. The changeover was in the very early 50s, so the engine in the photos could have been a 3.4 litre from an XK120, as stated earlier in the thread. The Mark V saloon made at the same time never had the XK engine, the Mark VII was the first in 1951. I can't find out when the changeover to front studs was made, so some Mark VIIs could have had the earlier cylinder heads.

 

thanks fraser the engine number is a early mk7 @ 7 to 1 comp but I didn't know if they were off that engine to start with as it is also fitted with a mk1 or 2 sump.

 

Actually, I was wrong on the intro year for the Mark VII. It was October 1950 because I had a look at a book by Brooklands Books I was very recently given, titled "Jaguar Cars 1948-1951". It consists of a collection of magazine articles of that time, UK and US. Autocar has a picture in its Oct 20 1950 issue showing the Mark VII with a "ghost" drawing of the mechanical layout, and two photos of the car, plus a photo of the XK engine, and that engine has no front studs on the camcovers. The magazine Motor also has an article dated Oct 18 1950 providing a lot of details on the car, plus photos, but none of the engine separately. So it seems the front-studded camcovers may have been introduced in 1951 or 1952. The Mark VII was for export only for quite a while.

The 1950 price is interesting - £988, with UK Purchase Tax of £278, quite a whack of tax !!
