Camshaft removal tips from the veterans

[shayne86]

Hi all.

Thinking my old girl MAY be in need of a new camshaft. 280,000kms on the clock, plenty of grunt off the line but runs out of breath once its moving.

My question to the more experienced landy owners is
1: can it be done in situ? Or this a full motor out affair?
2: anything else worth doing while im that deep into the motor? Timing chain, water pump etc etc

Cheers

TD5 or V8?

TD5 or V8?V8. 2004 model if that makes any difference

What else could cause it to run out of breath?

With radiator and timing cover and gear removed the cam should just pull out. New cam, lifters needed - you need to take advice on whether cam bearings should be replaced - normally I wouldn't unless something obvious but you are hi kms. This engine can only take a single timng chain so is likely stretched a bit so new timing gear as well.

I was looking at full kits with cam, lifters, chain, sproket etc etc.

Just wondering if there was any other hidden nasties to look out for while i was there.

Depending on driving style - eg towing, torque etc consider an specialist cam with characteristics suited to your driving. However if you are happy with what you have just a standard cam. With timing cover off (at your km) consider a new oil pump, renew serp belt pully and tensioner bearings or just replace. Other than cam bearings in the block there is not much else.

Also consider buying one of these

In an RRC you can also just lift the aircon condenser with say a come along so that it clears the cam coming out.

I do not know about a D2 , but hope it is possible to do it also, as it is a PITA to degas the aircon to remove the condenser and then recharge it.

Add twin TD5 turbos?

To get the cam lifters out, the tappets, pushrods, rocker gear and inlet manifold have to come off as well.
gaskets for these usually included in camshaft kit

But then, literally, 10 bolts later, per side, and the heads can be removed, (well, yes, exhaust manifolds), easy to freshen up the heads, reseat valves (lap) general check.

I would do a compression test before starting, it's simple, just to get an idea how things are, cam wear can give less power, but it happens so gradually, hard to tell if that's the cause of it running out of steam.

I've done a few Rover V8's, with those sorts of miles, it always starts with a simple cam or head gasket change or the like, and ends with full engine out rebuild.
But that's me, can't put things back together knowing other things are worn. Luckily, these old V8's are relatively cheap to rebuild.

It's like opening Pandora's box, how deep does the rabbit hole go?[bighmmm]
