Just finished puting my thor 4.0 back together again after new:
Camshaft
Lifters
oil pump
timing gear
oil seal
water pump
sump gasket
Starting her up was a nail biter. It sounded like a bag of spanners in a laundry drier. Kept my nerve and set it at 2000 revs for a minute or so, and now sounds like a kitten with a bowl of john west best.
The lobes were worn and the chain was slack, so it breathes a lot better has more grunt and more importantly does more mpg and better still its on gas.
So well worth the effort. All rads had to come off. The air con rad was leaking anyway so replaced that at the same time. I took the oil cooler out as one from the pump juctions as ive heard stories about trying to undo those nuts either side of the oil rad.
So dead chuffed with no more oil or water leaks. The cam , lifters , sprockets and a lot of the gaskets were Britpart and had no trouble with them, so its not all doom and gloom with them . All parts supplied by Island 4x4 with next day delivery.
The air con rad was from ebay for £79 inc next day, which was fantastic value and was of good quality and fitted well.
 
I would never use anything other than o/e lifters - even "quality" performance ones. Standard lifters are cheap enough and are far, far better quality than the after-market stuff.
 
Willos - Congrats on getting your engine back together. How long did it take? Any problems on the way etc pics?

I have mine in bits (Thor) down to the block. Just doing the gaskets but wish I had the time, money etc to have put in a new camshaft. Not looking forward to pulling the head bolts down 20 90 90 as not a lot of room to swing a breaker bar.
 
Do the shaft at the same time as its simple to do.
As you have the top end out only a couple of hours more work to do shaft.
Take all rads off and front cover. Dont take water pump off as it only wants the cover bolts off and it will come off with it.
Its well worth the effort and if the head gaskets gone then its probably time for a new cam anyway
 
Yes, good advice, Rover V8s wear cams heavily since zinc has all but disappeared from modern oil. I keep toying with the idea of putting a 270i piper cam in mine as the stock one must be one the way out by now at 130K miles.

That is good advice and something I would recommend to anyone but this engine has to be on the autoban in 4 days time so its just the top end this time. Have built a few 3.5s and 3.9s and other makes over the years and have always found a new camshaft works wonders. I bought a 3.9 once which overheated badly but with new mains, rings, camshaft and lapping in the valves she ran beautifully. On this occasion no time and keeping cost down (which might go against me!). 4.6 was running great prior to missfire so hope she has a bit more life left.

Something I'm contemplating at the moment - pretty sure I have a leaking head gasket so will definitely do the cam and lifters at the same time.

Trouble is, where do you draw the line? Thinking I might get the heads gas flowed while they're off etc etc!

Willos, what sort of valley gasket did you put back in? I've heard very bad things about the composite ones...

Two gaskets available composite or tin. The composit will reduce the compression a tad but has the advantage of being more reliable. Elring composite gaskets are the ones to use. If you go tin then Payen are the ones to go for.

Composite gaskets are better at sealing and probably last longer.
 
I used the Britpart tin one , which fitted fine. I just used some liquid gasket on the front and rear two inlets as these are water, apart from that fine.
I did look at the original lifters and compared with the Britpart ones and they looked identical in every respect. The fact is if the oem parts were so good in the first place then id have a boring time on here. The oem parts have always been rubbish so dont fly the flag for something that was poor in the first place.
sorry but 12000 miles is just about right for anything to fail on a Landrover thats done 141k miles. If it lasts another 30k i will be happy.
I have a long list of things need doing on it. One failure always means having to replace or upset several parts to make good the job.

No one is suggesting all OEM LR parts are great, but, the lifters are, they may look like Britpart ones - hey a bit of metal is just a bit of metal, but you know they'll last 60K-150K miles - after-market lifters just won't. I once made the mistake of building a Rover V8 with aftermarket lifters, 13K miles later I was ripping it down again - four or five lifters shagged and one of 'em took a cam lobe with it - and that was before the world was inundated with **** Chinese-copy parts. I've built five or six Rover V8s over the years - the only issue I've ever had was the one time I didn't use OEM lifters - but then the guy I built the engine for supplied them - they were part of a kit from a reputable performance cam manufacturer. BTW at least four of these rebuilds were with after-market cams so it wasn't the cam that caused it.
 
If any of the followers go south then i shall let everyone know on here.
Ive had non working parts from my main dealer, but no one says keep away from Marshalls bedford they sell dodgy parts. Bad news travels a lot faster than good, and i make my own judgment on parts. Its a good job a lot of parts are available cheaply as you can forget second hand land rovers. I paid out £210 for parts to do the front end and cam. This wouldnt cover the cam from a stealer. So the price for parts and someone to fit it would go way over the value of the car
I dont have any leaks or rattles or bangs. I took my time over it and happy with results 300 miles later.

I bet oem part failure is the same or worse than Britpart.

to be fair, that comment is nonsense

Britpart are just a supplier, who source from many many different manufacturers

some of those manufacturers use chocolate instead of steel - some of those manufacturers produce very high quality items

Correct.
 
Sorry but with the way weve handed over all steel and nearly all plastics over to the indians and chinese expect a lot more crud from all corners of the supply chain. Dont Tata own land rover ?
Hands up who have more factories in their town than 20 years ago .
Again because its more does not mean its better.
Quality control is only as good as the factory allows after an initial inspection.
You dont have to make spare parts to the same standard as the original. Cars are warranted for 3 years from new inc labour so you have to make sure parts are top notch all the time or its going to cost you . Aftermarket Parts 12 months at best and thats a grey area as it can be claimed youve abused them.
Name one part that still makes the original part from the original jigs and has not been taken over and costs analysed, or sold or now part of a bigger group
