Oil pressure.

Coul;d even be a timing chain noise, if its there all the time then less cause for worry in my books.

It is most likely a lifter Phil. If you are losing sleep over it, and I know when something bothers me I do, then the only real course of action is to replace them all. This means that you also need to replace the camshaft. If you can locate the specific lifter that is the cause of the tick, and you wish to take a gamble and just replace the one, then give it a go. The likely outcome though is that the noise will return and you will need to do it all again, including the camshaft. The timing set will also need replacing as the OEM items have nylon teeth and they break and fall off.

I know of another Rover 3500 that had a noticable tick back in the 1980s. That Rover is still going, still with the tick, the engine still original.

I took a video of the noise, I will upload it for you to listen to it..
How easy is it to change the cam and tappets? Do I have to take the heads off? How expensive are all the necessary bits?
 
Bliney! We are listening to a V8, aren't we? Sounds like it's missing to me, and the high level tick could be a sperk going somewhere it shouldn't - eg cross sparking between leads? Try having a look at the engine running after dark, see if you can see anything.

If as chris suggests it's something electrical then you'll save yourself a whole lot of trouble changing the cam and lifters! Definitely worth a check, don't get downhearted...

Don't loose heart Phil . If you've had oil starvation to the top of the engine you may have no more than a worn rocker shaft and rockers . Mine was tapping away quite loud and ruining the whole v8 experience ! I stripped it down and made a decision on how far i needed to go without replacing things needlessly . The individual parts aren't expensive but costs can mount up with gaskets , seals fluids etc . You may get away with removing no more than the rocker covers and rocker assembly / push rods . That's all i needed to do to loose the tapping . I did go on to replace weeping head gaskets and water pump while it was in bits but none of that was to do with the tapping .
Don't give up on her yet .

My point exactly Phil. Ticking noises won't stop your Rover... :wink:

It sounds to me as if you won't be happy (not a criticism just an observation) until you rebuild the engine. So to replace the camshaft after first having removed the radiator, water pump and timing cover, then remove the inlet manifold and cylinder heads. Take the sump off as when you attempt to remove the lifters, chances are they won't come out so you'll need to push them through so they drop out the bottom, naturally the camshaft has been withdrawn in order to perform this task.

So basically you have the whole motor bar the bottom end off and out of the way. A major rebuild and not something to consider lightly. Once all back together, the engine must start straight away, no grinding on the starter. Likely damage to the camshaft will result if this does not happen.

To me the noise sounds like a lifter. Drive the car for a good 10 or 20,000 miles and see if it sounds any different. No worse, no change in oil pressure or performance, then keep going.

There's no need to remove the heads to change the camshaft/followers/pushrods/rockershafts. Most of the time you won't need to remove the sump either, but it will give a better result as far as the timing cover/sump joint is concerned.
 
Hello Harvey,

I included the heads as I figured Phil might like to change the head gaskets while the opportunity presents, especially as the inlet manifold will be off. Save doing it a second time.

I have been doing some more poking and listening..

It is better when cold, noisier as it warms up. It is the O/S bank, towards the front. I think it is a tappet.. I think it manages to hold the oil when it is thicker, (cold) but not as good when it is thinner.. Hot.
 
Could a thicker oil help? (I'm not an expert... just thinking it might be something somebody more knowledgeable might be able to confirm or not...)
 
I'm using 20w50 Millers. I don't think it was this tappy before the change.
Anyone any thoughts on that wyns lifter treatment?
 
Take the rocker covers off . With a stone cold motor and see if they're is any movement on any of the rockers . their should be none .
 
That sounds quite ok Phil, certainly nothing there to become worried about. Please,...enjoy driving your Rover :wink:

Ron.
 
Definitely oil around in there, and no more than regular valve gear noises, I would say. As Ron says, Keep on Trucking (or is it cruising?)
