V6 oil pressure issue

Priming these suckers is as easy as dropping the fuel (ECU, relay, fuse, plug, etc...) and turning them over with a gauge hooked up. Same as an LS. That's all I've ever done in all my recos and builds, works great

Haha we actually did that just as a precaution but then we later found out that it builds up next to no pressure this way haha. Also works better without the spark plugs in

You can hire a air primer. It looks like a 4kg gas bottle and you pressurize the bottle with air. You hook it up at the oil pressure sensor and it fills all the galleries and primes the lifters after a few hand rotations.

That would be ideal.

Yep on the plugs. It's not about building pressure, it's about getting oil ahead of the 8 ball before a first start so it builds pressure quickly and nothing relies on assembly lube for more than 10-20 seconds. If it's built right, non firing rotation presents zero risk to internals

Air primers are more for non standard bills with remote filters, oil coolers and turbo lines where they may have extra litres of volume to cover external to the engine

So I pulled the motor and sent it back to the builder. Turns out it had grit in it still from beforehand. Which went through the oil. Nightmare.

Thats not good.

That is terrible. Hope you don't have to pay again?

I don't think so. He said he's gonna re-do everything for me. I assume he's just as frustrated as me. Originally it was full of crap when it got torn down. It must have had some more in it somewhere. My oil was going black straight away. Even after 5-6 oil changes.

Considering it was like that he probably should have had it soaked in the tank.

That's a pretty nOOb mistake given the gallery sizes on an LS, does he prepare/machine his own blocks?
