Can anyone identify this small 90 degree hose please.
​​​Just spoken to SNG and they don't recognise it. I thought it was a bypass pipe of some sort. Down low on the left under the carbs by the distributor. From a 1968 MK2 240. Thank you. Ron

 

I have seen a hose off the back of the waterpump to go to the heater, but never going forward. What does the other end connect to?

Tell us where that pipe goes to.

 

3 options:

if it is a 5/8" inside diameter it must be a coolant hose to the heater valve,
.
or it could attach to the air cleaner.

or if it is a vacuum hose it would be 1/4" inside diameter.

 

Whats this one supposed to do? Just found it dangling at the back of the engine bay. Comes out of the bulk head by the heater box

 

that looks like a 4.2 engine, not a 3.8, unless the cylinder head covers were replaced.

that hose could be the cowl drain hose.
if it connects to a pipe that comes out of the firewall / bulkhead, it is the cowl drain. It should be oriented to the ground following the firewall and held in place by a row of foldable clips.

Test it:
1) get a glass with some water,
2) run the engine and open the fresh air vent, (the cowl air vent between the wipers),
3) empty the water into the vent and see if it comes out that hose.

 

Hi Jose. Thanks for this information. I posted questions about identifying my engine in an earlier post. I thought I'd got it nailed but yesterday I tried fitting an oil filter from SNG and it was way to large. I'd given them my engine number 7J2850-8 (C24502/1C part number stamp?) Now you've made those observations I'm a little confused. It's also got a radiator expansion tank as well (albeit a home made one)

Ron,
the engine Valve Covers look to be from a 4.2 engine, the 3.4 and 3.8 valve covers were polished aluminum. But you can use either on either engine.

To confirm what engine you have:

Look under the intake / carbs side of the engine with a bright light; About 6 inches from the front of the engine, you can see the Litre Size stamped on the block next to where it has "Jaguar" stamped. It will say, "3.4, 3.8, or 4.2 litre". Hard to see but you might try taking photos with the phone. If it says 4.2, congratulations, you have a powerful engine from a 420 or XJ-6.

As to the oil filter, Jaguar used many different filter heads in these engines, depending on the country the car was exported to, so you need to go to an auto parts store with the oil filter that you removed and get it matched. It comes down to the size of the threaded hole in the filter.

 

2.4 stamp sitting bold and proud!

 

2.4 or 4.2 ?

 

Definitely 2.4! Other stamps are Ff27830 next to the 2.4.
In-between valve covers at the rear is DX529
Other side of block is A5 20-10-67

 

not familiar at all with that engine. After 1966, all MK-2 shipped to America were 3.4 litre and renamed "3.4", no longer MK-2. Same MK-2 body, but different badging. At that time they were trying to sell the S type over the MK-2 but buyers kept screaming for the MK-2 so they kept making it until 1968 and maybe 1969. The owner of British Auto Wood dot com brought his 1967 3.4 from Wales to Florida. The car is like new.

 

Jaguar 240's & 340's (Later Mk2 body with slim bumpers) both had Ribbed cam box covers.

 

the 340 I have seen in the US had the aluminium cam covers, not the ribbed ones used in the 420 and XJ-6. If the owners replaced them with the classic ones, that's another story.

 

Some 240's and 340's have the smooth type covers and thick bumpers like my car.
They started out as Mark II's at the factory and were finished as 240/340's.

There is at least one longish thread discussing this.

thanks, that explains it.

 

This is a 1963 Mk2 under restoration. The rear body pressings of the deep bumper Mk2 were quite different to that of the 240 & 340 slim bumper models.
