if the head gasket had blown would it start okfeel the problem is more ;like a misfire
there is no signs of water vapour from the exhaust
if it was head gasket how much power would i lose

Haven't we all!

The car becomes undriveable - which is just as well, because to drive with blown gasket ruins the surface of both head and block. Get the spare engine ready Dennis ! But to be honest - |I think your misfire is something else - are the valve gaps correct (12 in and 15 ex) ?? HT lead loose ? Try another dizzy cap and leads. Maybe it's the coil ???

changed points, dizzy cap, leads condenser , all one by one
and no difference
valve gaps all ok on saturday
i will double check these gaps

the car is drivable and the misfire seems less at 50
it starts up first time no problem hot or cold

ok started to misfire again an number 2
took plug out and it was oiled up tried to clean bu nothing put anothe new plug in an fires on all 4
so i guess possibly oil ring gone
have checked valve gaps and all ok and none sticking

have you done a compression test may show something up.

If the plug had not been firing the plug could well be oily/petrol, not the weather for an engine out job.
Thanks for that link earlier.

Excessive oil coming down the inlet valve stem? What's the history of the head - does it have the later Mini type 'top hat' seals on the inlet guides??

all new valves and seals on head

Getting back to basics, if the problem wasn't there before the head swap then I'd now be thinking the trouble is with the head or gasket. If trouble persists then you'll have to bite the bullet and take it off to see.

well the engine has done a lot of miles
and it s about time i got a recon one i think
there also a slight knock
it started playing up with the old head
will peruse the situation over the xmas period
thanks for all input

Oh didn't realize you had the trouble with the old head fitted. good luck anyway.

started about 7 weeks ago off an on

Hope it lasts 'till the weather gets better, not the sort of thing you need this time of year. Them days are over!

will pay someone to do it
agreed them days over

I'm talking about this time of year, they're not over in the warm weather! I haven't thrown the towel in just yet.

ditto
but needs must , need to keep it on the road for work and hols
