Well peeps, I've been an idiot, the story:
My Gt had been making some not so pleasant whining noises from it's gearbox, so with massive thanks to Dangerous Dave (who supplied the replacement, top fella) I pulled the engine out and swapped the boxes over. It was at this point I'd decided to fit the recently purchased (from a member on here) shiny powder coated rocker cover.
Fifteen miles later and my oil pressure gauge is reading slightly lower than it should, so I drive it very gently home (was only a mile or so away) thinking I'd not tightened a hose correctly and maybe running low on oil. Get home and the exhaust is belching blue smoke and my oil pressure is nigh on .1 bar at idle.
Popped the turbo off and there was no oil residue in the exhaust manifold but loads in the elbow, so stuck on my spare turbo fired it up and no more smoke, problem cured or so I thought, still had slightly lower than normal oil pressure so idled the engine till warm and the pressure dropped off again. Decided to drop the sump in case the pressure relief valve was sticking open or something, this was not the case, the problem was much worse.
Turns out whoever powder coated the rocker cover didn't pay enough attention to cleaning out the grit when they'd finished sandblasting it, a **** load was hidden behind the baffle plate, i'd have though the postman would've dislodged most of it kicking it around the depot, obviously not, it's ok though my engine oil washed it all out, needless to say my engines internals are now mush, and the shiny rocker cover? Mashed with the biggest hammer I could find.
Wish I'd never bothered buying it and just repainted the flaky original, but it was only £17 so seemed a good deal. Hope this tale of woe prevents something similar happening to anyone else.
