Well last night, although short of time, As it was suggested I fit Thermostates, I thought I would try an idea. I have no States to fit, but instead fitted two large washers with 15mm holes, therefor reducing the flow and as Goanna suggested allowing the rad to filter slower.
I fitted them where the Stats go, in the top of the heads.
Ran the engine, again at idle no problem, but when increasing to high revs, it was not as bad as without the restrictors, however as soon as I throttled back, up it all came in spurts and spots!
Perhaps my 'restrictors' were the wrong side of the pumps ?
So, Tonight I will try the Holts Rad flush!
I am most grateful to you guys for all your suggestions, it's quite reasuring to know we have this community of help and advise.
The saga continues!
Will it be at Trucks and Troops,? or will I have to use my Trusty old GPW!
