would it be worth swapping out the cams if the engine has only done 60000 miles,or would it maybe compromise the engine if they were replaced with cams from a high miler?presuming of course that any 3.0 being broken would be high milage.

[MutantCav]

I wouldnt have said personally that the cams would be one of the items that would have a massive wear and negative effect from high milage...

[stuthespread]

but they do wear out,how could you tell the good from the bad without fitting first?

[markey mark]

of all the engines i have stripped never seen any wear on cams at all i even sold a set out of a siezed engine and the car give over 200bhp on rollers 

[deviator]

The only real wear is caused by an oil feed problem and you would feel grooves in the camshaft. There is often a bit of wear on the lobes, that is normal - as long as it still feels smooth.

[stuthespread]

so what sort of realistic gain would i achieve by swapping them out?and what would be involved(parts needed etc)

[stuthespread]

you can tell i'm not at work today

[deviator]

I don't know about the gains, I thought it just swapped BHP for torque or vice-versa.

No parts (except cams) needed.

Tools however are a different matter, torx bits (int & ext), cam lock off kit, T26 socket (or 16mm double hex), pipe clip pliers, torque wrench spring to mind.

ADDITION
You will need some gasket sealant for the rocker gaskets. If you are replacing use only VX genuine ones, pat parts are awful.

think the 3.0 cams add 12bhp to the 2.5

i have two sets of them here mate if your interested? £105 posted

Adds approx 18-20BHP and some torque too...as Markey says, never seen any appreciable wear on any 3.0 cams I have ever seen...just a matter of stripping it down to replace the middle inlet cams with the 3.0 ones and putting it back together including of course retiming (and the timing must be spot on!)

[Martin_1962]

Work well on 2.6 as well

but they do wear out,how could you tell the good from the bad without fitting first?

Would need to use a micrometer to get the cam dimensions, I would think.

The followers are of a larger diameter than the cam lobe is wide so there would be no appreciable wear ridge on the cam itself to guage it by.

[The Red Baron]

quick question H21, are the followers the same on 2.5 & 3.0l.  :-?

[924boy]

are there any other parts from a 3.0 worth putting on a 2.5 to improve power apart from the cams?
