Hi Chaps, well if itโs possible to feel relieved and disappointed at the same time, then that time has just arrived !
I have now stripped the Engine, fully expecting to find a number of broken Piston Rings in the Sump, but no, all the Piston Rings are intact ,so why the horrible cacophony thatโ my Engine has been emitting and why was there Oil dripping out of the Inlet Manifold on Noโs 1 & 2 Port ?
The only evidence I had before stripping the Engine, was that I could โRockโ the offending Pistons easily in the Cylinder Bores , ( Especialy in No 2 Bore) now the Pistons have been removed intact without the broken Piston Rings I expected, is as you will be able to see in the pictures below, there does seem to be excessive โScuffingโ on all of them.
This may have been caused by the fact that the Pistons were supplied with the wrong size Rings fitted ,( allowing a 0.062โ gap to be found when placed into the Bores !! )
which with hindsight ( wonderful thing that !! ) I should have checked prior to building the Engine last year( but who does ?) maybe this caused more wear on the Pistons than I thought when I stripped it recently, to fit the correct sized ones , anyway , I shall take the Cylinder Block , Pistons etc to my local Engine reconditioning company,
( Cox & TaylorTintinhull Somerset) and get Ian Cox to measure everything to try and find whatโs going on !
Anyway, here are some pictures for you to peruse over, on these dark dank evenings, your comments would be most welcome
Ps , Not sure why the bottom picture gets โStretchedโ when enlarged !
Cheers Al
