A question. Has the tappet been noisy all the time since initial startup or did tappets go quiet then this has appeared over time?

They never really went what I would call quiet although they weren't horrendously banging but this one developed quite quickly and got worse.
The job is done now, was a follower stuck in, bought another and changed it, all back together and sounding much better.
The cam looks fine, no scoring on that or the scrap lifter so maybe it was just a faulty part.....always happens to me though :doh:
Some pics........
Bad.........
Good....
See the difference? Bastard Range Rovers!

Not the half of it yet mate, just been out, dual carriageway, goes from 30mph to 50mph on a hill so I gives it a bit more boot, kickdown and back to 7 pots (if I'm lucky).
Got the car back and had a look. Inlet manifold valley gasket has an upward bend and the inlet is blowing into the cam/lifter area.
Now then, I didn't replace the valley gasket with a new one when I removed it today as it had only been on a couple of days and covered just 50 miles, so, I used a bit of gasket maker (the stuff I had from the sump) and coated the heads and the inlet manifold surfaces where they join then refitted the gasket and the manifold.
Question is really, if the gasket has failed, will it cause itself to lift upwards due to whatever pressure.
It is also 'chugging' (like a bad exhaust blow) from under the inlet manifold and not firing on all 8 (now theres a surprise).
As for the lifters, supplied by 'thelandroverexpert' (ebay user name) although the shop name is Landrover Specialists Online. No idea what make they are but deffo an odd failure which I now think has lead me by the hand into committing further stupid act of corner cutting and will force me to spend another god knows how long fixing it again.
If the bassas had sent decent lifters in the first place, I'd be on here praising how good my P38 is and blowing raspberrys at Fett :lol:

ha ha regarding the p38 bit.
nah sorry its a fooker, yeah when they blow they do bulge so time for a new one mate.
I am sticking with dingo croft for my parts becuase unlike paddocks the guy actually knows about the landies and can advise rather that filing her nails inbetween calls like most operators.
I wont buy mehcnical parts new from ebay as its probably ****part or there rejects!
atleast you will be good at the valley gaskets by the time this is over mate

We have an update. Stripped it and I think the pics speak for themselves.
A brief explaination, helicoils in the centre 2 bolts were fitted at the top of the block and not screwed down to the bottom of the hole. When the head was torqued, they pulled the threads and basically when the torque wrench clicked, it was the helicoils tightening up against the head. PS, an LPG backfire probably caused most of the damage but the backfire was probably caused by a number of things, one being a coil pack wire not being tight on the coil, second being valley gasket, third being the helicoils/head gasket.
Never mind, as you said Fett, I'm getting good at this now.

The chugging would have been the blown head gasket, the tapping was the fooked tappet as posted earlier.
All fun eh haha. Parts ordered again, at this rate, I'll be on 1st name terms with the suppliers.

Aye, pain in the ass with the cheap parts but at least I'll get the job done in a few hours now I'm more familiar. Parts already ordered and need to build the funds back up, I can get the good stuff next time.
Probably the wrong attitude but I did say that if it does 20,000 miles, I'd be happy before another strip down.
Dingo and Island have websites with prices?

Update time........IT WORKS (again).
Running better than it did last time, new plugs gapped properly for the lpg, head torqued properly this time with no issues and its just completed a 100 mile round trip without a hiccup.
I'm claiming a victory at the moment because after last time, it wasn't right from the start lol.
Still got a bit of engine noise, hopefully tappets but more of a dull thud than a tap, and stops when the revs are raised but is present when the engine is revved.
I don't care about the noise though, it runs and runs well, and it starts on petrol then switches to gas as it should now (old fuel pump was fooked so was starting on gas). No backfires and all seems to be as it should be.
I'm happy for now, lets see whats next.
