[xj40] Steam Generator

Well, it’s finally my turn. Looks like a blown head gasket since it
produced such a thick cloud of steam I could not even see the cars behind
me. Luckily I was only a couple of miles from home and made it back.

I am having difficulty in locating a good deal on the hose kit for the 1993
model 4L. I’ve checked the online Jaguar parts distributors and eBay. I’ve
seen them before and meant to a set but neglected to do so. I think $75-$112
is a good deal but cannot find one now for this model year. Does anyone know
who still sells them? I think the part number would be HK-40?

I remember somebody mentioned once that they had a cam alignment tool
template or a way to make their own. I have some sheet metal if someone has
the precise dimensions. I would like to make one if possible.

Why couldn’t it wait till Spring?–

Mark,

There are some ‘loaner’ clones of the Jag cam tool in the US which
someone on the list may be able to mail to you. That tool holds
each camshaft (separately) in turn in the correct position for
timing.

Alternatively, if you have a suitable piece of plate about 3 or 4
mm (0.125’’) thick you can make a simpler version very easily which
locates both camshafts in the correct position in relation to TDC
#1 cylinder and each other whilst you fit the camshaft timing
sprockets.

You need to cut the plate in an inverted ‘U’ shape looking like a
soccer goalpost. The ‘uprights’ must be exactly 6mm wide (to fit
snuggly in the slots in the camshafts) on 139 mm centres and the
underneath of the ‘crossbar’ should be about 45 mm high with a
sufficient depth to keep it rigid - say 15 mm.

I used that alternative method on mine and it ensures there is NO
chance of one of the camshafts moving as you juggle with the chain
and the splined timing inserts in the camshaft sprockets.

Diagramatically, upside down, it looks like this (hopefully)

 6 mm                                              6 mm

Ahh well, the diagram didn’t work but I’m sure you get the
picture! :-)–
