Spark plug blew out.
Lucky I was about 1km from home and I drove it back making a hell of a racket. Phoned my mechanic and he said maybe it was a carb plug but I rooted
around and found one of the plugs blown out.
The thread does not look stripped, but I am guessing the thread in the head is? I can't really see down there to have a good look.
I don't really know much about engines...would this even be worth repairing? Should I just try screwing the plug back in? How much do I screw it in?

You should be able to feel it if its stripped, sounds like it is though - a helicoil can fix this quite easily - inexpensive and quick. Its like a
thread insert.
Others may have a better idea - i did this in a past 1600 with no issues

Have hada similar experience remove the lead and try n screw the plug and insert back in
you may get away with it
Screw it in untill it goes TIGHT with a bit of luck
other wise the insert may have to be redone bit of work
Where are you located Some good VW shops can fix this

which plug is it, i had to do one and it was a pain but i was lucky it was on number 3 so it wasnt to bad to get at, had a mirror and a torch to see
in there, the hardest bit was removing the tang on the helicoil, tricky bit to do had a magnet stick in there to make sure i didnt drop it into the
head but it got stuck in the cylinder and was a pain to get out. if it were me id get someone to do it for me

It is the one towards the rear of the vehicle on the right.
I'm gonna look tomorrow and see how the hell I can access the 'port'? where plug goes into the head. I am guessing I need to get underneath the
vehicle because from the decklid end it is covered with some sort of cowl? thing?

Yeah that is what I mean; it is a kind of covering.
I can't get my finger in there far enough to feel the threads.

... don't feel for threads - yet - just try screw it back in. Plugs will gradually work loose and go poop...pooppoop if they aren't torqued properly

Damn I think it is stripped because I tried screwing the plug back in and it won't 'bite' and just keeps spinning. It sure is an awkward thing to
try and do.
Havn't a clue what to do now...gonna search on google. Worst thing is I can't drive it to a mech.

you can drive on three cylinders but fuel will be squiring out. Has anybody done it before?
Do you know anyone who is good with helicoils or similar.
Others will probably have better ideas. DOn't get stressed, its not a big problem to have.

Ah PERTH that explains a lot
Sorry Dont know Kurt but have a try and see if he can fix for you
Sounds like you may have to pull the engine and get a proper helcoil insert installed
Was the insert one of those copper type inserts the stainless ones are much better

Sounds like a good way to turn my bug into a burnt-out bug. 
It also make an embarrassing racket. Maybe I can shut the fuel off to that cylinder?

The head is made from soft alloy so the spark plug thread will always be the stronger thread...
this can be common... mainly from spark plugs that have been fitted without Never seize compound...
If You can jam the spark plug in there somehow..
maybe a slightly larger spark plug... it cannot be any LONGER than the original spark plug.. [into the cylinder]
a piece of very thin metal wrapped around the plug then the plug knocked in carefully with a long spark plug socket
could keep you going for a long time... lol
naturally, its easier to fix with the engine out of the car and the head off...
JAX Heads sell nice reconditioned heads....
I would go that way..
as the other spark plug could be ready to pop too..
Steel and alloy expand and contract differently , thats why never seize should always be used...
Its difficult to stop fuel from going into that cylinder...
as its sucked in...
best of luck..

Hey! This may be an obvious answer, but I know in Brissie there are mobile guys who can put in a helicoil. A number of my local mecahnics use a mobile
helicoil service and just job that kind of work out. If there's not one listed, then maybe a call to your local Kmart tyre and auto (if there is one)
would put you onto the right people locally? When I lost a bolt from my exhaust where it connects to the heads, I had a mobile guy out to put in a
helicoil, and it was $70 for the service - $10 less than the local mechanics were going to charge for the same deal. That's assuming you intend on
going down that road, of course.

with the plug out there would be no compression so it wouldnt draw in much if any fuel
i remeber seeing tyre inflators that screwed in place of the spark plugs years ago

I think this is an engine out job. I cannot imagine any way to do a decent job with a helicoil, with the blasted tinware in the way of seeing what you
are doing?
