Do you have learning view? If so, hook up and do the ecu reset. From memory that causes the car to crank for a period before starting the er, start sequence. It theoretically gives some oil pressure thus oil in the places you want oil. Would be a lot easier than removing the fuel pump fuse.
Kinda flush. Fitment is something. ADM as F*ck.

Buddah and robbks

I don't think the forum really gives two hoots as to what bogan antics you or your (irresponsible) employees used to destroy vehicles in the manner you described.

The fact that you both seem to think its fine to fire up an engine that's been sitting for so long without priming it first suggests you have no idea about tolerances and lubricantion systems.

Fact remains, a 'performance' motor such as the ej's can receive a significant amount of damage if started without priming after sitting for so long. And no about of Internet bs you guys dish out will change that

So maybe stick to being experts on lubricating each other instead of commenting on my understanding of lubrication systems which the OP might follow and end up with a pitted bearing as a result.

Ian - that was my suggestion to someone in another tread (ecu reset) but pulling the fuel pump fuse is so easy it's not funny. Also, learning view reset (and even sometimes a full ecu reflash) doesn't guarantee default settings are triggered - which means it won't do the three second crank thing)

OP - your call at the end of the day but for the sake of a ten second job to remove fuel pump fuse I would definitely rather be safe than sorry.

when did you last do your brake fluid? mine was WAY more than 3 months ago.. still stops fine.


There's a lot of difference between a car that sat unmoved for three months and a car driven even only once a week for three months.

If there was significant water in the brake fluid already, it would have accumulated and could be causing rust. And that can certainly cause problems.

In the end - especially when talking to someone about a car that isn't mine to destroy, I take the conservative and cautious approach when giving advice.

I think that's the point dumb and dumber seem to miss

Why dish out advice on a whim "she'll be right" when this person can rely on this info and cause some damage

Just because it worked in a bogan stealership for shit boxes that were going to be sold to some shmuck that the dealers couldn't give two shits about, it shouldn't be the standard on a forum for enthusiasts who actually care about their car's health

Well the car has been driven by me and I was giving it to it but tht was 7/3/13 and since then it has been at my parents house, and I know they have moved it a couple of times since then..

So when I said it hasn't done any work, I sort of stretched the truth :oops:

Guess how your new Subaru was treated........
by the same breed of underpaid "bogans" that exist in every dealerships pre-delivery department.

as for an EJ being a "performance" engine.. HAHAHAHAHAHAHAHAHAHAHAHAHAHA
there's nothing sophisticated about a late 80's designed boat anchor,...

As for what I know about Lubrication systems specifically and other Thermal and Fluids Engineering topics, I've got the papers to prove what I know.

And as usual the original poster has neglected to include VITAL information that completely changes the advice that's been given after two pages of bullsh!t.

It would be prudent to take dr20t's advice and prime the engine before its first start. It would also be ideal to let it idle to operating temperature and drive it gently, staying off boost etc to confirm normal operation.

Also redlining new engines is not standard practice and is likely to cause severe damage and reduced longevity.

It is in dealerships....

I read a very nice materials engineering paper a few years ago that outlined the benefits of putting new engines under hard loads frequently (after a warm up)
Lots of technical jargon but in essence the regular stressing of components while they are new and a little more "elastic" within the structure of the alloy itself, helps them retain that elasticity for longer. And doing so (sensibly) on a regular basis prolongs the effect.
Not to mention the higher heat generated helps in the removal of varnish, gum and carbon deposits from your internals.

I too have read a few articles that basically say "drive it the way you'll always drive it" when it's new. The theory is that this helps to "bed in" engine components, and results in piston rings that form better seals with the cylinder, etc.

It flies in the face of what manufacturers say, but I can see the logic behind it. And the few articles I've read on it have come from guys who spend a lot of time pulling down and putting back together engines, so I figure that they may well know a thing or two on the topic.

100% agree with this rob - and wasn't saying anything about this in my earlier advice.

What I was suggesting earlier for first start up had nothing to do with this though.

In the old days the way to run in an engine was to thrash the shit out of it whilst being conscious not to hold revs at a fixed point which may glaze the bores before rings are bedded in

MSR has told me that the REX's and LIB's that he has tuned with the highest Dyno readings have normally been driven hard by their owners straight out of the dealership. I would have thought running them in gently would have got better dyno results.
