![]() 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 ![]() ![]() ![]() 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 |
