Hey guys
Am new here and looking for advice/ information on the 3v 5.4 v8.
I'm looking to buy a 2004 ba falcon xls ute that I've come across, its tidy 4 spd auto with good ks has the 5.4 and is also gas injected.
I took it for a test drive and it drives great apart from a few little niggles is almost "perfect" for what I'm looking for.
But on start up it has a ticking that doesn't go away even after warming up, it doesn't adversely affect the performance of the ute coz it goes well but that noise is always there.
After talking to a few people they've all offered up different ideas as follows:
A: cam lashing?
B: it's the gas injection and it's normal for that
C: timing chain?
It's at a good price but is unreg'd so I don't want to be buying something that's gonna cost big on to fix b4 I even get it on the rd.
Any informed ideas as to what it might be and the possible repair cost would be greatly appreciated.
Cheers.

My first thoughts are timing chain issues. Second would be the gas injectors, but they really don't tick all that loudly.

Can you hear the noise with the bonnet closed? If so, timing chain issues, ie worn guides, tensioners ect....

Which is a time bomb waiting to happen. I had the timing kit replaced on my wifes ba xr8, and only a few months later the nason supplied kit become noisy suddenly. Turns out the tensioner failed, and the Oring in it was leaking oil pressure, resulting in a slack timing chain. This was fixed, but not all expenses were covered under warranty.

Then, barely out of warranty, without any warning, the same tensioner that started to play up last time (whole timing kit was replaced), failed suddenly and catastrophically. Timing chain slipped, bound up, broke the cam gear, and bent 31 of the 32 valves. $4500 damage to the engine.

If you buy/ thinking about it, get the timing chain kit replaced asap!

Cheers

No Worries mate.

My wifes BA Xr8 is liquid gas injected(orbital), you can hear the injectors tick slightly with the bonnet open, but you can't hear it with the bonnet closed. We also had a Ford Motorsport oil pump fit ( BIG $$$ )when the timing kit was first replaced, as these v8's are known for wearing the oil pump gears and having lower than ideal oil pressure. Ford actually specify the Motorsport pump as the service replacement for a standard pump.

Cheers

The ticking is normally Phasers and I have no idea on price or what damage would result if not changed. Timing chain tensioners is normally a rattle that goes away after oil pressure builds up. If the rattle does not go away, you would need to turn off the car and walk away or replace timing chain tensioners.

even with the bonnet shut the ticking was loud and clear, but yeah have decided to give this ute a miss just too risky.
