Ok cool i will do that thanks for the advice clyons8!!!

If it is dry or starved temporarily, it is good practice to run the engine without plugs in to ensure the oil circulates properly and fills the circuit. It's not protocol but just a good habit to get into. This enables the oil to (comparatively) gently move throughout and pressurise the circuit.

You did well not to run it too long. When the engine is freshly rebuilt it is also good practice to pack the pump with a denser material like petroleum jelly, just to assist to begin the circulation. I used grease once but have since been told that is a bad idea as the oil does not break the grease down, potentially creating a 'clot' if you like. Also remember to fill the oil filter with oil if you are replacing it.

Sweet sweet thats good to know thanks guys.

Yep, should be fine.

It should be OK.

Hey guys short story shorter, i just took the a12 out of my vb10 to do rear main seal and its the first time ive ever taken an engine out before anyway all went well til i put coolant in and even after i was told by the father inlaw to right myself a note to put oil in, I FORGOT TO PUT OIL IN!!! One of the stupid many mistakes i suppose im going to make. Anyway i ran it for a max of 60-70 seconds with no oil before i turned it off, waited a minute to inspect then filled it up with oil and ran it for a minute... There werent any knocking sounds or anything as far as i could hear...

such a pity i think i did everything else ok!!!

Can i expect anything bad to come from this!?!? Will it blow up? Should i take any action? Im a bit of a newb :/

cheers
