Putting this here as well as in ask gunning thread as no reply there yet

Hey ppls I have a few questions about my Ford Falcon EB Gli 93 4.0 litre Sedan.
Would appreciate any advice anyone can give me.
I bought this car about 2 months ago, cost me a grand plus about 800 to get it on the road. Its had an LPG convert, not an x-taxi however the previous owners and their kids were rough on it.
Firstly, about a month ago I found water in the oil,<img border=0 src="http://digilander.libero.it/katalog/emo/No/smile_no0003.gif" /> quite a bit by the looks of it which explained why I kept having to top up the radiator, I thought I was losing the water originally from the lower radiator hose but it looks like it was somehow getting into the oil through the head, wasnít like that when I bought it. <img border=0 src="http://www.ezboard.com/images/emoticons/mad.gif" />
I drained the oil and refilled after putting on a new oil filter, run some chemi-weld through the radiator after flushing it and replaced the plugs, I guess this is what the previous owners of the car did before selling it. <img border=0 src="http://www.ezboard.com/images/emoticons/devil.gif" />
Its running ok now and the oils looked clean for a week or so but the cars beginning to run rough, idling very low and missing a bit. <img border=0 src="http://www.ezboard.com/images/emoticons/eek.gif" /><img border=0 src="http://www.ezboard.com/images/emoticons/eek.gif" />
Theres also this ticking noise in the motor sounds like its coming from under the tappet cover, im assuming this noise is caused by the lifters?

Also when I changed the plugs a while ago I noticed that the first plug had half of its lower thread rusted away, didnít look to healthy. Was a LOT of carbon on it but it just looked really sick, the rest were okÖ well not ok but in need of changing.<img border=0 src="http://digilander.libero.it/katalog/emo/No/smile_no0008.gif" />

So what do you think ppls. Am I up for a new motor? Or just a new head? Or could it be just the head gasket? How long will I be able to drive this before something dies in it? Will driving it make the problem worse even if ive stopped the water getting into the oil? Other than idling rough it runs really well out on the road, not really much power but that would be caused by it being an auto and running on gas right? Or would these problems contribute to a lack of power?
I got a few quotes on having a recon head fitted, prices seemed to vary from a grand to $1900, does anyone have any ideas where I could get a replacement head at a reasonable price on the east coast, im in queensland, hervey bay if that helps
Do I need to replace this head with another 4.0 litre head or will a 3.9 do the job?
I did find a replacement head at the wreckers close by here for $250 but the wrecker said it was from a newer model engine than mine so im wondering if he meant it would fit ok?
Finally, I have to move to the gold coast for work in one month and was planning on taking the ford, do you think it will make it the 400ks or is it going to leave me stranded if I donít scrape up the cash and get it fixed before I go? Im guessing it would be cheaper to have repaired down there anyway.
Thatís about it, let me know what your thoughts are on this, if you need some more info on anything let me know.
Thanks <img border=0 src="http://jabberwoq.com/images/emoticons/idea.gif" />

I would say blown head gasket. While the head is off, have it milled flat and checked for cracks. You might want to have the valve spring tension checked and the valve guides and seats checked.

It's due for a reco head but the price you've been quoted seems way over rated I'd say you don't have much work shops to go to so hence they can get away with over charging people.
As to getting your car to the gold coast 400k away you will be very lucky if you can get the car there.

I'd say that the water ports on the head have started to corrode so they will weld them and then the head will be machined and cleaned with new valve's etc the cam will be extra or just replacing the lifter's will also be extra.

The worst case you need a new engine it could also mean your piston rings may also be warn if you don't have much power since you mentioned you run it on gas as this is what gas does to your engine if it's running on gas all the time.

this doesnt sound to good, though ur probably right, if its going to cost me over a grand to have a recon head fitted whats it going to cost to replace the motor? i shudder to think, and we wont know if the motor actually needs replacing till the head comes off right... maybe i should just sell...
the previous owners ran it only on gas, and never ran coolent in it i found out today, well thanks for ur advice

such is life

Yeah sounds like you brought a dud there must be some reason why they were running it on gas all the time.

Hi Guys
I've been told by my mechanic , a "glitch" with the 4.0L motors are the "head studs" original ones had a tendancy to stretch , hence lots of blown head gaskets , when he checked ours "pre purchase" he said the head had been replaced but put new stud in "just to be safe"

Get the Parts Peddler book.


Falcon I6 Motors $1600 exchange plus fitting.

IMO i would not stuff around with it. because all the money you will waste on fixing it over and over again. it would be cheeper to replace the motor.
