Well lets see, my 300ZX sat for about 9 years before I cranked it.
Changed the Oil, pulled the ignition wire and cranked it for a few turns and started it up.
Put in a little fresh gas and some seafoam, was at about 1/4 of a tank… Ran it dry, changed the fuel filter, put more gas and seafoam in… and drove it… Ran it 6 months after that before I tore the motor down and rebuilt it when I converted it to a turbo.
I will tell you this, I did not find any nests etc when i first looked, nothing ran out from the car… but if there is a chance for mice/small animals to get in that sotrage container, I’ll bet between the block and lower intake manifold there is a nest from something in there… There is JUST enough space for something to build a home in between there, I was shocked at how much shit was in that small ass spot when I took the motor apart.
Very true , most pumps don’t have enough power to lube top end till 1100 r.p.m,s !!! That’s why on new motor break in they have u hold r.p.m,s at that so that the oil gets up top .
Well let’s put it this way, I can hand crank my Nissan engine (with the plugs out so there is no compression) and get oil to come out of the cam squirters. The only time I could forsee an issue is with aftermarket bearings, since a pump and bearings are what create oil pressure…OP your fine just go to town on it.
That’s typically because the pump design has poor scavenge(suction) on the sump, or is worn the fuck out. Hence why its a damn good reason to pack new oil pumps on new/rebuilt engines with a tacky prelube as that almost always ensures the pump will scavenge and prime. If you’re having a hard time getting a pump to prime on a motor that’s been sitting for an extended time, loosen the filter to reduce the back pressure on the pump until oil flows from the filter housing.
All this BS is why I force prime a new motor with an accusump-style setup I made to ~90psi through a main galley port or off the filter housing via an adapter before I even start to crank it over to build pressure on it’s own. System is primed and to pressure almost instantly upon first fire up.
All nonsense in this case though. fire up, look for leaks, listen for weird noises, watch oil pressure/temp/coolant temp based on gauges in car. Fresh gas fresh oil, go light up tires. I just fired up the lemons car which has been sitting outside for over a year now, still has the same gas in it from ~4+ years ago when it raced. fired right up and ran no problem.
In all seriousness, I usually Pull the fuel pump relay and turn over the engine a few times until the oil pressure gauge reads pressure or low oil light goes out. My new oil pump was disassembled for some tacky assembly lube. Like Adam said. Its hard for a dry pump to get a prime and could potentially harm the pump and engine. Your engines pump should have enough oil in it to prime up tho.
