URGENT oil pressure stop engine

Only different is your not turning it over fast enough for it to start.

Not quite true...
By hand, almost no possibility of causing additional damage (assuming you don't use a big breaker bar, torque multiplier or similar - I've seen it done!).
By starter motor you add a mechanical gearing effect, and some degree of momentum from the running gear/flywheel etc, as well as compression gas loadings, even if the ignition/fuel pump are isolated so as to prevent firing. So must be greater risk of more damage?
And if turning over/running at tickover, then all of the above plus firing gas loads too.
Go slow n steady, one step at a time, it's not a big engine after all, not that hard to turn over by hand...
Take the plugs out.
Ladies tights make an excellent impro filter/strainer, and will catch all debris if you pour your oil thru them. Get your lady to take them off first tho :grin:
Ps I'm not a car mechanic, but am a mechanical engineer and have seen some spectacular engine damages over the years.
I really wouldn't risk a start without a very good look at the internals!

Oh, so really I need to remove the oil pump :sad1: Im going to hazard a guess and say this is beyond me. I think its garage time :(
andy1979uk:
If you remove the oil pump then it's £60 just for the stretch bolts to refit it. New oil pumps are £900 and good luck finding a secondhand one, sometimes easier to just cut your losses and get a new engine. As the others said by the time the light comes on the damage is probably done.
r5gtt:
If buy a Chinese copy oil pump if the oem are £900 smackers :stupid:
Pesky jones:
I'm thinking if I remove the cover plate on the bottom of the crankshaft, and also the oil pump cover, I can check for damage on crankshaft and also the oil pump sprockets etc. I'll also check the oil filter and sieve/ magnet the oil.
I've just got it in my head that I don't want to write the engine off and start looking for a new engine if the problem was actually simple. If I can't see any evidence of metal in the engine oil or pump, then surely it's worth a try, if there is metal in there then the engine is already shot :signLOL:
