[xj] back with a bang

Hi all,

it’s been a while since I was last here, but I had to share
this one: our '88 DD6 has issues with the LH tank, where
miniscule flakes of rust drop down, causing the injectors to
go nuts if the tank isn’t drained every now and then.
After a drive last night B-bank was missing 4 and A bank was
missing 5, so I took the plugs out, applied power to the
injectors to squeeze the goo out and refitted. I’m still
puzzled as to what went wrong next, but when I started the
car aa few hours later I heard a big ‘‘BANG’’ and the engine
wouldn’t start. I opened the bonnet and a burning smell was
quite obvious. Then I noticed that the dizzy cap had been
blown to pieces: 6 no less, with the top part right in
halves. This when the vent system was in place. Fortunately
nothing else got damaged, so a new cap was fitted and normal
service resumed (except that 4B still fouls, although the
plug does spark). My dad’s on his way to France 1350kms with
that car: hope he makes it in one piece.–

Fuel is supposed to go into the gas cap, not the dist cap, Arnoud.

Hope your dad makes it ok!–

In reply to a message from Arnoud sent Thu 8 May 2008:

Unlucky. Was the vent system open and connected right with the inlet pipe well away from the valley or any fuel source? There must have been a very rich vapour near the left inner wing for it to suck a combustible mixture into the dizzy. More likely there was some spilled fuel in the valley from injector replacement. On the carb models it was never an issue as all sources of fuel and leaks were outboard of the cam covers so evem raw fuel dribbling from a connection would not get under the dizzy cap.

It would get on the exhausts though :slight_smile:
