Owen369 Posted August 30, 2016 Share Posted August 30, 2016 First time subaru owner. Went for a real nice hawkeye in blue sti wheels and spoiler on totally standard engine and body work is mint condition.full subaru history head gaskets/cam belt/ service done 4 thousand ago by subaru. Car was fine. Until half way home(60miles) then noticed it was very hot and she cut out. After long story i currently have the engine stripped and may be looking at 2 new heads and all the bits to go with them. Happy first subaru times 👍 Quote Link to comment Share on other sites More sharing options...
stants Posted August 30, 2016 Share Posted August 30, 2016 Hello & welcome, sorry to hear the situation your in, have you contacted the seller ? Something was obviously amiss Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Owen369 Posted August 30, 2016 Author Share Posted August 30, 2016 Yes got £400 back at least its a start on the rebuilt bill. Car has only done 3-4 thousand miles in last 2 years. Water pump is fine and can not see any split pipes. Just so disheartening wanted one for ages buy one and blows up on way home gutted to say the least.

Tidgy Posted August 30, 2016 Share Posted August 30, 2016 welcome. sorry to hear your problems. and time for the bad news. budget minimum 3k for the rebuild. will need a full strip down and crank bearing replacement plus what ever else has been damaged. You need to get it to a specialist who can sort it properly. If it's not done right it will fail again and again and again. If the garage you bought it from wont agree to pay the full cos of the engine build including crank bearings (based on being several thousand) then reject the car can get your money back, don't risk it cos you'll end out of pocket with a knackered car.

Gambit Posted August 30, 2016 Share Posted August 30, 2016 I'll start by saying welcome to S.O.C and sorry to hear about the engine the 2.5engine bit known for going like that unfortunately but looks like you know how to twistle some spanners so should keep the costs down. feel free to start a project thread to log your progress and keep us all up dated. I'm guessing taking it back now isn't an option with it being stripped. Quote Link to comment Share on other sites More sharing options...
Owen369 Posted August 30, 2016 Author Share Posted August 30, 2016 Was a private sale but totally trusted the car as is mint an all history ect. Which is why i went for a nice one not a thrashed one. Yes luckly my family are handy with the spanners so no labour costs. Got to take heads to see if there ok today after work. As the cams have started to eat at the metal. (Can see on pic) to see if i need new heads. May start a build thread but just want to boostttt [emoji22] Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 30, 2016 Share Posted August 30, 2016 Will highly likley be bottom end damage as well, so make sure to replace the crank bearings as well Quote Link to comment Share on other sites More sharing options...
Owen369 Posted August 30, 2016 Author Share Posted August 30, 2016 And no chap would not take car back same old story you have thrashed it on way home ect. But motoway is mostly 50mph anyway these days. If he would of had car back I would have never of brought another one really put me off hope is ok when its all back together Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Piggysniffer Posted August 30, 2016 Share Posted August 30, 2016 Welcome aboard mate, I feel your pain, what's this about the cams eating into the heads ? Has it been run low on oil do you think ? I think tidgy is right, if your thinking of keeping this once fixed it really needs a full strip and check, also, how did you remove the avcs pulleys from the cams ?

Gambit Posted August 30, 2016 Share Posted August 30, 2016 Once it's built again mate you will love it but I'll go with the others and being the 2.5 engine it's worth making sure everything is done and use good strong parts and it will last you out for many years all being well with some nice boost Quote Link to comment Share on other sites More sharing options...
Piggysniffer Posted August 30, 2016 Share Posted August 30, 2016 252498844669 this guy on eBay selling both heads, they were originally £20 cheaper each, but he's upped the price, you may be able to have a deal on both if need be, can't vouch for him as never dealt with him Quote Link to comment Share on other sites More sharing options...
Owen369 Posted August 30, 2016 Author Share Posted August 30, 2016 Have seen those heads will see what head place says today and maybe offer him 300 for both. Got pullys off using the bolt extractor method as it goes on outside of the bolts not !Removed! hex inside (gives more leverage) air gun would not touch them big bar and the handle off trolly jack. Whats this about the crank bearings then? Thats a engine split job? I believe the chap had the car serviced regular but who knows. Would like to track problem down as water pump and no split pipes Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 30, 2016 Share Posted August 30, 2016 Basically when the head gasket goes water gets into the cylinder. Cos it wont compress the bearings get pinched and damaged. They then have a nasty habbit of failing after 1000 miles. Which would mean another fulls trip down and rebuild doubling the cost. Given your 70% of the way there it would be daft not to. Mate found that out the hardway ;) Quote Link to comment Share on other sites More sharing options...
Owen369 Posted August 30, 2016 Author Share Posted August 30, 2016 Thank you for the info. Even though its just killed my day [emoji22] more stripping to do [emoji22] i hate subarus Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 30, 2016 Share Posted August 30, 2016 yeah sorry :( if your gonna be going that far then worth looking at uprated pistons, rods, headgasket and headstuds. will stop the same thign happening again and if you do it right will run 450bhp no problems Quote Link to comment Share on other sites More sharing options...

classic mica Posted August 31, 2016 Share Posted August 31, 2016 welcome mate I feel your pain that's so bad luck. Just shows you never know, atleast you got some cash back. Quote Link to comment Share on other sites More sharing options...
Mr B Posted August 31, 2016 Share Posted August 31, 2016 Bearings normally damaged if water in oil & been like it long time. Would take hell of a lot of water in cylinder overload bearings due to hydraulics (water injection for example doesn't kill bearings) & you would bend rods too. Do any cylinders show signs of water ingress ( look nice & clean) As situation unknown and seller obviously sold knowing had issues & been too tight nip it in bud it needs strip down & full check, Rebuild with new waterpump cambelt etc, oilpump seals and shells if needed, check pistons well & bore spec too . If rest of car A1 then probably will work out good in long run, more an issue with seller really, subaru boxers are pretty solid for ragging they get . 1 Quote Link to comment Share on other sites More sharing options...

Owen369 Posted August 31, 2016 Author Share Posted August 31, 2016 Bin told that can not machine them as its a high performance head. Has took good chuncks out of cam lobes. So if take metal away ie clean them up. be no oil pressure around the cam as tolerance will be to big Sent from my iphone using Tapatalk Quote Link to comment Share on other sites More sharing options...
Tidgy Posted August 31, 2016 Share Posted August 31, 2016 You can do some machining, not sure how much you can get away with Quote Link to comment Share on other sites More sharing options...
Mr B Posted August 31, 2016 Share Posted August 31, 2016 You can do 2 things with score marks in cap & head bearing wells. 1. if not deep can be polished out . 2. if deep, head cap face is machined down a fraction making hole fraction smaller & then it line bored & polished . Lot of machine-shops will say can't be done but it because they can't do it, not got the kit or experience. You need a proper machine-shop do this work and fussy one too (not many PROPER ones about) If cams scored get new . Have done this on couple builds we done & finish & spec spot on but does need expert & fussy machinist for proper worthy end result . Cam journal load is minimal compared to say crank so it easier rework & tolerances although important have more scope . With cams like that I think you will need crank bearings for sure, we can normally judge by pre strip oil pressure, stethoscope check, oil condition, head gasket leak internal/external & condition of bores/head & cam journals how good bottom end going be ...
