ok had this engine for a while, when it 1st started it would be spot on but after a minute it would lose oil pressure (lamp flickering) and after a few seconds of this it would get a tad growly (not knocky but just noisier)
now i figured its gonne need a grind and some shells (like the other 4!!! engines in my shed

the shell (pic) seems to be over 1 side a bit too much, you agree??, its located propperly in the indent, while im on the subject the top shell is grooved but the lower 1 is solid, this right?? been a few months since i stripped a cvh and i cant remember

and as for the oil pump, its fooked hence im hoping that while it caused a drop in pressure it will also be the cause of the noise thus the lump will be fine with a new un fitted

engines been together for very few miles so dont wanna split the head off or have the crank messed with too much as its recently been done
