if it sat in a dry place then you should be just fine to crank but not start. U may have smoke every start up since the valve seals got pretty dry, but i wouldnt worry about that.

there is no oil pump piston, its a rotational pump but a fresh subaru engine not wanting to prime is a common issue, some say leave the oil filter empty so the pump will have an easier time to push the oil through but the safest way is to dismantle the oil pump and pack it with assembly lube or even petroleum based vaseline.

Then why do you just crank newly build engines for example to build up oil pressure?

@cruizinmax4017 I don't know, but I seen a video once where during a rebuild they put some oil around critical components during assembly. But I have to admit that turning it by hand with the plugs out is a good way of getting som oil to swish around ,or the cold crank like you say

​@@cruizinmax4017the idea with an engine that's not fresh built is the piston rings are possibly stuck to cylinder walls or will have more friction than a freshly put together engine with installation lube and pre oiled cylinders

Use a engine pre-lube tank. holds 4 quarts of oil you can inject into the engine through the oil pressure sensor. Rotate engine by hand while the tank injects in new oil. Fully pre-lubes all oil circuits

Not really

I would put a scope through the sparkplug holes and inspect the cylinder walls, if you cant do that then gently turn the engine and try to feel for any obstruction with the plugs out, rust might be present, if motor is stock or you do feel something then put ATF inside and wait couple of days, then turn and feel for it again, if all good then crank with sparkplugs still out to clear the cylinders, its going to be a mess....then start...expect a lot of smoke.

How did this workout for you?

check oil before starting, pull an ignition fuse or fuel pump fuse or relay, or you can just disconnect the coils on top of the engine so spark plugs dont fire, crank until red oil light turns off, about 10 seconds should do it.

Sorry for the late response. I would unplug the crank sensor and pull a fuel pump fuse then just crank like I did in the video. Killing fuel means no fuel will go down cylinders while cranking. Unburned fuel washes down oil from cylinder walls. Warm up the car for 10 mins or so, then change oil.

@@cruizinmax4017 thasnks alot i will let you know how she purrs

@@aaronferguson9328I’m having the same issue did it work bro?

i was an idiot, decided to prime the starter a few times to turn it over a few turns, i have not yet found my issue, it dies when i come to a stop, the left side of the motor injector is way louder than the others, it pulls timing then kicks in , then kicks a extreme lean fuel trim code, put 1 full b-12 chem cleaner in the fuel, and .5 seafoam in the crank case, maybe it will clean the injector idk wtf to do@@alwresendiz3826

Just start it. All these theories that people spew around about the first start being such a huge deal is mostly BS. What's worse is that many of the suggestions given are more damaging than just starting it. If you really want to go the distance in doing it the best way possible; pull the spark plugs, coat the cylinders with oil, and crank it 'till you have oil pressure. Then put the plugs in and start it. Coating the cylinders means wetting the entire circumference of the cylinders, not just squirting a little oil in. Since your cylinders are horizontal you'll have to use something to get oil to the upper side of the cylinders. With my 911, which has the same style of cylinder layout, I used an air blow gun with a long tube that had a slight bend at the tip. I put oil into the tube, put that in the plug holes with the bend facing upward, and blasted the oil into the cylinders. Mine was an extreme case, it had been parked for about 10 years, the oil had been drained, and several parts were removed which drained even more oil than normal so I felt the need to pre-lube it. It took a very long time cranking to make oil pressure since everything was empty, yours won't be as bad. Oil doesn't go bad from sitting, but if you feel the need to change it, do it after you've run it.

add gas before start, warm up the engine for about 15min and then change the oil but make sure the oil level is good.

It should be easy on any vehicle, just find the fuel pump relay or fuse under the hood or inside under your dash, you can also look for the ignition fuse, pull any of those fuses or relays. Its better to kill the fuel pump so no fuel gets dumped into the cylinders while cranking. Cant really lubricate cylinder walls or pistons from the top on a fuel injected car before start, you could but its more work and unnecessary. It was easily done on carbureted engines back in the day, you would just dump a mix of gas and oil down the carburetor but if you kill that fuel pump and give a crank until your oil light goes off you should be good.

@@cruizinmax4017 I think it's better for the fuel to be injected into the well since the gas can also serve as lubricants. so the better option is to pull the ignition power switch fuse

disconnect the crank sensor underneath alternator or an ignition fuse or fuel pump fuse or relay, then crank until your red oil light turns off.

Did not say that at all....You can winterize your vehicle or not, your choice. What Im saying is dont just start it after it sat for a long time, do what I did in the video before starting.
