Priming Oil System

@Jdmjunkie you certainly can fill your oil filter, and very quickly install it without spilling any oil.

There is absolutely no reason to do so. It dumps right back out.

Yep. And every single time you shut the car off as well.
The aftermarket has an answer but as often the case it is really just a solution to a very, very, very minor condition and something else that could screw up.

I've never once heard of that. Startup usually pushes the oil into the engine fastest as it gets the pump into a much more efficient pumping RPM vs cranking.



This I've seen other have issues with. A dry pump trying to push (purge) air through thick assembly lube does not always work well :/

Adding some assembly lube to the pump should always be done. I wish they shipped them this way. Of course, I wish they shipped them with bypass pistons that never stick and backplate bolts that don't come out too

I did the IAG recommended process twice and got no oil at all. Called them up and the front desk lady told me just start up the engine. Took it to a IAG gold certified shop and they said the oil pump was defective

Did a certified shop do the assembly and install? The pumps in these are stupid simple. The only way for it to not work is it is broken, missing, backing plate loose, or crankshaft extension installed incorrectly.

It's always a nail-biter watching the oil pressure gauge just sit there for two seconds while the engine runs at fast idle.

Meh. There is enough residual sitting on all the oiled parts to last that few seconds.
I have pulled apart engines that have sat in a field for a decade or more that still had residual oil on everything critical.

I bought a fully assembled and timed long block from them. I have my theories but it works now so whatever.

Do not recommend filling the oil filter on ANY Suby engines.

Think about the premise of this thread. It's all about purging the air from and filling with oil the galleries, passages and ports. If you take a dry filter element, and fill all the media's pores with oil, it has a harder time pushing the air through it. Which means it's more difficult for the pump to prime. What the difference is, I can't say. Most (nearly all) new EJ engine priming issues we've come across have been when customers filled the oil filter with oil.
