THis. And if water has entered the block then 9/10 you will need to replace bearings. It needs inspection as it’s pointless doing a hg and not checking (that is a gypsy way of doing things).
And as mentioned if bearings are fine, may aswell replace them with acl etc if they are stock for cost vs peace of mind for future.
or the person in question is confident enough knowing that they don't need to take the belt & braces approach of changing everything just incase? which in turn costs the owner less £££

Depends how much profit is in it for them i guess,
Where does it end,
New Rod Bolts, Full Rebore, rings the lot, all for a popped HG,
Yea there will be the rare occasion where that in a must, or mileage deems it to be more economical,
As says above you can tell by the type of failure if things should perhaps go deeper, or at least a competent person can without just throwing parts and money at a job.
My old hawk sti done it's head gasket @60k and was only skimmed/gaskets replaced (by the guy who built/owns the 10sec OMA Legacy so he knows how to build them)
it was still going 4yrs afterwards and it was a daily driver

see above quote from previous page...
skimmed with cosworth gaskets and new subaru headstuds to their torque spec and with that it was happily running 345bhp/395lbft Bob Rawle mapped in the years that i had it.
so this isn't just hear say on what your long list of crack engine builders tell you and then you rinse/repeat on here but actual fact that happened with me & my car.

and being Northern Ireland it only run on 97RON
not a chance in hell is a 350bhp car running high 8's
I guess you dont remember the thread on here then about a hawk with failed crank bearings that wern't done. Plus several that have bitten several tuners who no longer offer just a headgasket replacement job. Why do you think that is?

yours is a 2.5 right?
just shows you much you dont read the detail in a persons reply or on a topic in general if you start a reply with that line i have highlighted
let me explain it in short to you
you said ALL headgasket failures must have main bearings done as its a false economy not doing so.
i highlighted a personal example where proof that it isnt always the case.
which returns to my main point, you dont have any fact - its just hearsay that you rinse/repeat on here on a lot of topics because someone told you or you read something on the internet.

No were talking about robs car which is a 2.5, your car has zero rellevance, all 2.5's need it, 2.0 has never been mentioned at all, yet you shoved your gob in.
I also replied about about the legacy running stock bottom end, but you didnt bother to read it that way did you.
Actually no it isn't hearsay at all, i've seen the physical damage found when engines have been stripped on multiple occasions, its what happens when you spend time at garages that do dozens of rebuilds.
So the short version is you were deliberately arguing a cross point and just rambling on in the thread just to be a c$nt?
So a fair bit more than 100 quid added onto this HG bill now..........
Or just more bended truths from yourself
If you are going to strip them to check them then it would be good practise to check the fitment when they go back together, so your adding nothing except the cost of the bearings.

mine was a hawk sti, a spec D in fact, they where 2.5 as you well know so yes it does have relevance and again your above statement saying all 2.5 need it is false - not rambling at all simply pointing out a fact
ive no idea why you are discussing the Legacy - that was just me referencing who it was that done the work/headgasket on my car & that they know what they are doing around subaru's incase i get informed it must been some gypsy engine builder

I give up.
You wanna advise people they don't need doing then you crack on, when people come back and blame you that's your look out.

2.5's need alot more than just bearings for piece of mind.
So goalposts move once again and its only the 2.5 we are talking about....

i'm not advising anyone anything, they can all read what is said across the internet mostly horror stories and the odd good story but go with the advice that their subaru specialist tells them. You will agree that no specialist likes being told how to do their job

I think he is advising folk to make an educated decision.
If your not capable of this you rely on an honest competant tech.
Something you seam unable to grasp.
You statement saying all HG failures need bearings done is mince because there are plenty of circumstances where this is just not true as has been pointed out by quite a few folk now.
So new rod bolts too ?
or wait & see if they stretch 2nd time round if ur lucky....
Tidgy gets all his work done at ScoobyClinic, that's where all his "expertise" comes from regarding building engines. Cries like a bitch if you call him a fan boi mind.
He's right in a way though, if the block is split, it's a bit of a false economy to reuse the bearings. By then it's not a head gasket job though, it's a rebuild/refresh anyway.

Understand That, but it's advisable to at least check and throw some acl ones in there if stock while it's apart.
Saving money is never a good thing with these cars, do it once and all that

When I lifted my heads at 2+bar at totb, I already Decided to buy new bearings, gaskets and all seals etc as I planned on checking regardless, and since it was a stock ej207 it would be better putting some acl in there and at same time I could physically check everything else at same time.
No milky residue in oil, just blowing and loosing water out of overflow and this is what water/oil did to my cam housings on my heads, never took any pics of bearings as decided not to refresh and went fresh 2.1 block. But the bearings were in similar shape. Hence it's wise to check and not assume,
That's what happens when lack of lubrication, lucky not deep enough and fine polished out, but you get the jist
Mate, other people know better it seems.
And I'm not saying change, inspect 'at least'.
I'll even go as far as saying even some top well known tuners/builders have **** ups, even till this day, ATM I know of 1 big tuner who's riffling a mess at the moment who you wouldn't of thought it from, but funny thing is all these things are tight lipped.
Too many fans nowadays.
Customers constantly get blagged even today!
