Reply With QuoteProbably just got a valve clearance wrong. Sometimes when you do a job for the millionth time you get distracted, way it goes. It's something you should learn to do yourself, it isn't very difficult.

Okay I've just had a fair bit of work done by a very good mechanic, but I wanted to get the collective opinion on what may have caused my 300Tdi, my perfect sounding 300Tdi, to develop a pretty severe case of ticking noise straight after being in the shop.
Now it's had the rocker cover gasket replaced, timing belt done, front of engine pulled off and radiator and intercooler cleaned, tune tweaked up a little, and just about every hose and clamp replaced that you can poke a stick at that's worth replacing anyway. Also had the basic service stuff done like oil etc.
Drove it away and as much as I was hoping it would go away, it really does tick a fair bit now, faster and louder with acceleration.
This was absolutely no doubt in my mind not there before.
I've told the guy who did the work and am wait to see what he thinks, not trying to roast him at all with this I trust his work and his opinion on all things Land Rover...I just wanted to see if there's anything anyone could think of that may have caused something like this to develop. I am meant to be taking this car off on a pretty serious trip just after Christmas day and I can't have things like this hanging over it when it was meant to be all fixed up. Just trying to speed up the process of getting to the bottom of it and trying not to loose too much sleep.

I'm very happy to try and fix this myself...is this something I could do quickly and easily enough with the right tools? It's not like it's been driven much in this state so I hopefully haven't damaged anything, but it did to a long drive home from the mechanics in that really hot day we just had.Originally Posted by bee utey
Hopefully it's just something like that...is that something they would have mucked about with while doing a timing belt? When do valve clearances get tweaked or set in the scheme of things?

I did a mate's valve clearances this morning, also checked the pump timing. All in all an hour's work. The reason I did them? When he visited last month I heard his motor popping unevenly, found out his "new" aftermarket rocker arms were shot and a lash cap had fallen out. Courtesy of this forum I acquired a second hand OEM shaft and rockers, had them faced and fitted them up with new lash caps. I'll be checking them again in 1000km, then every 10K after that. That's what having a Land Rover is all about, keeping on top of the maintenance and catching things before they do any real damage.
To do the clearances yourself, all you need is a couple of spanners, a feeler gauge, a screw driver and something to turn the engine over with. I removed his fan so I could turn the crank from the front using a 27mm socket and ratchet. Oh and of course you need the instructions close to hand so that you do them in the correct manner and don't accidentally set one with too much clearance!

Sounds like something I can actually do in the little space I have...although after such a major bunch of work and a decent bill (which I was happy to pay mind you...not griping) I feel a little sheepish having to do something like that myself.
Is there any reason you can think of that these would have been changed as a part of that kind of work I mentioned? Timing belt, rocker cover gasket change, both of which they did do...they didn't mention anything to me about setting the valve clearances though unless they are just part of another job.

SupporterIt could be your serpentine belt got damaged at the workshop, Check to see if there is any damage to it.
Otherwise I would be insisting that the problem was rectified as it has only happened after you picked the truck up, Most reputable workshops will fix this "Gratis"

I have no doubt they would insist on rectifying it straight away, now it just becomes a matter of me being able to get there before the christmas shut down period which is the problem

SupporterI don't know if it is true, but it has been suggested that a leaking exhaust manifold can sound a lot like a ticking noise.
Have you checked that possibility?

SubscriberI'm with be on the clearances being out, last time I did mine after a head gasket change I set one wrong and it chugged and tapped like a tractor.
I have a laminated copy of the instructions if you want them.

SupporterCould be any of the things mentioned here, but valve clearance problem is most likely.
Been there, done that myself too.
Like BeeUtey said, and in your tool thread, start collecting the tools required for it and save yourself a ton of $s doing some stuff yourself.
Most difficult part of doing the tappets is removing the rear rocker cover bolt (oh! and the rearmost adjuster too, when your body is old and decrepit, like mine is).
Generally takes me about 1hr to do .. but then again I'll muck one up and it takes me another hour to redo!
I take my time with it, but I reckon if you just hooked into it, it's a 30min job.
600 mm long breaker bar with ratchet action($50-ish), fan removal spanner($25-ish), ring spanner(s) and short stubby flat blade screw driver is all that's needed.
For this one, I'd also say get it back there to get it sorted, but you should check them every 10K(ie. every service) .. so it makes sense to add that job to any oil/filter change, if you end up doing them yourself.
Do you plan to do your services yourself once you're able too?
Alternative to having instructions at hand would be to request a member from here to assist you, more for the guidance than the physical help. The work itself is easy... just a bit confusing the first time you try to do it yourself.
If you have a short bit of hose handy(which you should have some as a spare for your impending travelling!!) maybe 0.5m or so, you use it as a stethoscope and put one end on your ear, and then run the other end near(but not on) any area that sounds ticky/tappy.
So if you ran the other end of the hose about 5- 10cm away from and along the length of the rocker cover, you'll hear some rattly noises through your ear end. it'll have a certain volume for the most part, and if one is looser than the others it'll get louder. That louder one will be the problem.
Same with the exhaust/inlet manifold area too. One reply was a possible leak from the exhaust. Hose end along the surface between head and manifolds and you want to locate changes in volume/pitch of any noises.
There will be noises a plenty .. all you listen for is changes in volume/pitch.
Considering your trip plan to WA soon, (I can't remember) do you have a separate coolant gauge and EGT gauge?
If not, highly recommended to get them, especially travelling across the Nullarbor that time of year, with the possibility of 50°C heat, the likelyhood that you'll want aircon going full time, a strong headwind, etc, etc.
