|Rover Engine with New Cam Cover Gasket in Place.|
Car: 1999 Rover 800 825 V6 Coupe
Colour: Zircon Silver
The single biggest problem on all of the Rovers R8 models from the nineties was the problem of leaking/weeping Cam Cover Gaskets.
Although a leaking cam cover gasket, will not usually cause you any serious mechanically problems, unless you lose all the oil! They can look unsightly, and make the whole of the engine rather messy if just left to continue.
The Cam Covers Gaskets are a very easy thing to fix, and are also quite cheap to do, if you are prepared to do them yourself. You do not really need any mechanical knowledge to do them as it is quite a straightforward task.
The Rover KV6 engines use a flat gasket as shown in the photos (one for the front and one for the rear bank). Most of the other Rover engines use a rubber band type seal. Both types of gasket do exactly the same job.
To fit new gaskets/seals first you must remove the spark plug leads, so please label these beforehand (if they are not marked/numbered already), as each one has to go back in the right order.
Then undue all the cam cover bolts and remove the cam cover.
The old gasket/seal should be discarded (although check first that you new one is the correct size!).
The cam cover should them be cleaned and dried. You should also clean the face of the head block(s) on the engine, and make sure they are dry too.
Then place the new gasket onto the head or insert the rubber type gasket into the grove on the cam cover. These should normally be done dry, but as Rovers are prone to leaking again within a couple/few years many owners will also use a tube of gasket sealant, into the grove and onto the rubber seal once it has been inserted.
You should then place the cam cover gasket back in position on the head, and loosely fit all the bolts.
The bolts should be tightened in sequence, and to a specific torque setting, so please check these settings out before you begin.
Progressively tighten all the bolts in the correct sequence, until you get to the desired final torque setting. DO NOT over tighten them as you can warp the gasket/seals leading to the problem reoccurring sooner!
Then replace the plug leads in the correct places, pushing firmly onto the spark plugs, they should click firmly on!
It's then a case of just replacing any engine covers or other parts you have removed to gain access to the cam covers.
It's worth being able to do them yourself, as they will go again! Some owners remove the rubber seals, simply clean them up, and reuse them again using a tube of gasket sealant, but obviously this depends on the condition of the ones removed, but it does make a cheap fix!
It was only a few months after this Rover 800 Coupe had the Cam Cover Gaskets replaced, that the Head Gasket failure occurred (sods law!). So it has since been done once again using the new Cam Cover Gaskets that came with the Head gasket Set!
