Just try a lower oil level first. The problem might go away.

If you have original heads and valve guides then you can be sure the guides will be worn after 45 years of use.

I much prefer the do it properly version but would be happier if I could last till winter

And the rest of that post (before my sausage fingers tripped over my tiny phone keyboard!) was that yes Dave I'll try a different oil as I know my Dad'll have some if I pop round cos he has a couple of "older" motors Cheers guys, I just don't really wanna mess anything up if I go to the bats by being impatient

You need a heavy oil in these old engines. But keep it below the max level.

Valvoline Premium 20/50 works a treat and they do one in a red can for high mileage engines as well.

and you can never be sure that the dip stick is the correct one

or indeed the dipstick who put the marks on the dipstick was awake when he did it, too many extra fat ciggies at lunch time... makes Jose a sleepy chap

drain it

and add oil measured to the volume specified in the manual.....

any slight overfill is just used up in the new filter...

check where it is on your dipstick and remeber or re-mark with a hacksaw

You have to be careful when doing that Dave.

They usually specify Quarts and a Quart = 0.946 Litres

Joe Gibbs oil mate the only way to go for a flat tappet motor...
