I reckon it might be the oil thinning to much as it gets warm. I would go to 10w50 or something, I doubt it will see much winter use so a heavier oil is probably better anyway. You might want to try what flyerncle suggested ind bung some Wynns in there.
Hope it's easily fixed, whatever it is. |

Yes I,m using the standard mechanical fuel pump, would wear on the push rod cause it to run at a faster tickover ? I,ll whip it out tomorrow & have a look at it, I,ll check the book & see if it gives dimensions etc & if its ok to lubricate it etc. Thanks for the "heads up" , I didn,t think of the fuel pump cheers andy

Sometimes an exhaust gas leak from manifold to head can sound very much like valve tapper noise

Hi Andy, might be stating the obvious here but if the tickover is too high then just turn the idle screw down a bit?... and as Vern says the rattle will be just a hydraulic tappet or two, renew the set and you will almost certainly cure it, and use 10/30 oil. Dennis.

Thanks Dennis & Adrian, great info here
yes I have blocked off the breather that goes from the "frying pan " to the inlet manifold, I,ll check all the diaphragms tomorrow & with a bit of luck, thru a process of elimination of the all the points raised I,ll find the culprit, I,d really like my new tyres so hopefully this won,t break my squeeky budget thanks guys cheers andy

Mine did the same a few weeks back just after i got it on the road, it was almost a knock rather than a tap, i was using 20/40 oil
I put some engine flush in got it very hot drained it, new oil and filter with 10/40 semi synthetic and it purrs perfectly now i played with cvhs alot a few years back when i 1st passed my test and they do seem to do this when they have been stood a long time, sometimes some flush and fresh oil and a run out sorts it, sometimes it dont. Some people say if its goona be stood a while to take the tappets out and store them in a bath of oil. If you do need to change the tappets and want to do the stem seals whilst its in bits i have a tool to do the seals without taking the head off, giz a shout and you can borrow it if you like, i may even give you a hand! |

The hot bath of oil trick can help revive a tappet. They can quite often get blocked by solidifed crud.

A little update........
I,ve spent the morning working on the car, Solved the high tickover .......... I had not tightened a bolt that I,ve put into the manifold that originally had a pipe connected to the "frying Pan air filter" or the one going to the Brake servo ( which is no longer there ), so was losing manifold pressure, sorted Re jigged my throttle cable ( Thanks Spud ), all smooth & free running I took the rocker cover off whilst the engine was stone cold, I noticed that a couple of the rocker arms were a little on what I thought were loose, checked the bolts, all tight, didn,t go any further, Ran the engine up to temp, the tapping noise is still there, it seems to come & go to be honest, I,ll be changing the oil & filter tomorrow so will see if that helps cheers Spud & Mark...........might be a case I need you both to come & have a look & listen, see what you think ........please cheers andy
