You loft such arguments
I never argued anything, I'm here to learn and help.
Accurate information and options help people find the best fit for a given situation. This thread presents and option, I'm sorry if it comes across to negative or comparative regarding the EJ25, I really don't care too much about that. It's a great engine in plenty of circumstances and certainly worth repairing, I equally instruct, guide when people need EJ25 help and have repaired people's EJ25 headgaskets for free. Cut me some slack, I'm not that bad of a person I dont' think.
This thread presents another option, because options are good, and it's very attractive for some.
I think it's attractive because:
1. EJ22's are available and cheaper than EJ25's in many areas. see Car-Part.com--Used Auto Parts Market
Cost and availability alone are frequently attractive, particularly on 20 year old vehicles
2. EJ22's have fewer headgasket issues than EJ25D's.
3. EJ22's blow fewer rod bearings than EJ25's.
This is supported across a wide array of information sources. They can be named, linked too, and found.
If the EJ22 is a worse engine - then tell all, give sources, and show statistically significant failure modes so we can learn to address them. I'm all about it, I love forward movement - headed some where, actually gaining something, winning, and learning. let's do it. name it, claim it, point, link, prove it.
And if we're allowed to laugh a little here - again I'm not arguing or trying to be personal like some of your comments seemed - i'm just discussing and sometimes conversations are funny - seals are a bit funny to mention because the EJ25 and EJ22 have the same seals - same part number in the 1990's and EJ25's have twice as many cam seals of an EJ22 - 4 instead of 2. So statistically speaking (failure rate of a cam seal X every seal installed), they'll have almost twice the failure rate of an EJ22 if viewed as a Fermi problem across decades and 100's of thousands of engines).
(technical note: EJ22 and EJ25 failure rates will differ by very small margins due to heat, head, oil supply differences of design, but those differences will be small compared to the orders of magnitude difference of an EJ25 having twice as many seals and points of failure as an EJ22)
About seals - older seals were worse materials (typically black) than the newer brown (typically) material of OEM seals. Again - true of the EJ25 and lots of other Subaru engines. The older EA82, ER27 stuff had the black seals and they were definitely not as robust.
You loft such arguments in favor of EJ22 yet drive the six cylinder instead. Does that not make your anectdotal condemnations of the newer four cylinder also hearsay?
I'm not sure what that means?
I drive a 6 cylinder for room, latch (not available in the 90's or 2.2's) and rust has all but ruined the 90's market stuff where I live unless you really just want one.
I did favor the 6 cylinder over the EJ25 to avoid EJ25 headgasket issues and timing belt maintenance. That's a lengthy discussion though, but I'll leave it at that for now.
