B-BGTLimited Posted May 1, 2013 Share Posted May 1, 2013 To sum up my incident... Misfire on the higway at 70mph smoke and knocking... And #4 plug bent over from foreign debris... It Begins... http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0036_zpsbddf46ca.jpg http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0037_zps82880cde.jpg http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0038_zpse46f815b.jpg 156k Miles on this setup http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0040_zps34276563.jpg BOTH Cars down right now... the toy and the DD... WTF! http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0041_zpsc277f24b.jpg Got my cam holding tools today and they came right off... Go figure. Head removed from 2 and 4 http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0010_zps1eba8f3c.jpg Head looks to have survived enough to be refreshed and re-used. http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0020_zps1d4b407e.jpg http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0022_zpsbb906bc0.jpg Headless... http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0015_zps8dab153d.jpg http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0023_zps0eedc073.jpg http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0017_zpsbf6b7dc8.jpg I can only get #4 piston out without a huge alan wrench http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0024_zpsd183047a.jpg http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0027_zps33b5bddf.jpg Fits on the bench... LOL... http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0032_zps8af1f1a2.jpg Scored Cylinder http://i257.photobucket.com/albums/hh201/3400modified/Leggy/DSC_0033_zps4ed85fa7.jpg Hope to talk to the machine shop tomorrow and then drop the stuff off and maybe get the pistons ordered by Thursday... Going with CP Forged pistons and I think I can get away with .25mm overbore so if that's confirmed by the machine shop I'll order those and have him do the machine work. After that's done, I'm doing all the assembly myself. I'll be doing a full gasket kit obviously... A full set of bearings and sending my injectors out for a cleaning... as well as thoroughly cleaning everything that came off this. I don't plan on doing any more performance work than whats already done on this car, I would just like to get the forged pistons in there for a piece of mind.

Max Capacity Posted May 1, 2013 Share Posted May 1, 2013 Sounds like a good plan. I was thinking the head wasn't going to be to bad. It's amazing how much the head can take and not look to bad. Sometimes you get lucky. When you get the gasket set, make sure the half moons are in there. Might as well get just a timing belt too ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Yeah going to, just forgot to list that. May also upgrade the clutch and grab a tsk3 kit. Not needing a head will allow me to buy those extra items. And your talking about the half moons that are in the heads right? What are those cutouts even for on the head?

Max Capacity Posted May 1, 2013 Share Posted May 1, 2013 The half moons are the seals in the back of the cams in the head. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs.

heiche Posted May 1, 2013 Share Posted May 1, 2013 Maybe the half moon cutouts are there to allow original machine work of the cam bearings? BtSsm - Android app/Bluetooth adapter. LV, logging, gauges and more. For 05-14 Legacy (GT, 2.5, 3.0, 3.6), 02-14 WRX, 04-14 STi, 04-14 FXT, 05-09 OBXT Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Maybe the half moon cutouts are there to allow original machine work of the cam bearings? That's the only thing that I could think of... otherwise its a bit odd for there to even be a cutout back there. Link to comment Share on other sites More sharing options...
tytek Posted May 1, 2013 Share Posted May 1, 2013 How about a killerb oil pick up, since you have everything apart? Link to comment Share on other sites More sharing options...
Max Capacity Posted May 1, 2013 Share Posted May 1, 2013 How about a killerb oil pick up, since you have everything apart? Good thought there, Check the oil pipe real closely. I just reused mine, it looked in good shape. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 I was thinking about it, but honestly it's really not necessary if you check and re-braze the stock one... But i'll see what my prices are looking like on parts and maybe I can fit that in. Link to comment Share on other sites More sharing options...
06silvarubiLGT Posted May 1, 2013 Share Posted May 1, 2013 ^covert/tigworks was cheaper and thing was beefy I posted some pics in the WDYDTY4GT thread Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Where is that one? I found a Moroso one for $86 Found the Covert one for $129 from IIR We'll see what all of this other stuff comes up to for a price first... LOL Link to comment Share on other sites More sharing options...

B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Its $168 vs $129 between the two so the price difference isn't huge... the Moroso one for 86 however that's a decent price difference. It's just a matter of how good the Moroso one is... Link to comment Share on other sites More sharing options...
06silvarubiLGT Posted May 1, 2013 Share Posted May 1, 2013 every little bit helps in my mind. but you are correct. I was impressed with the quality of the covert tube, welds were great and it was a very beeft product, never set my hands on a Killer B to actually compare to tho For peice of mind, I would replace it rather than re-braze it, just something about "re-doing" something that flows engine blood doesnt sound right Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Well I'm just referring to the reviews saying its way cheaper, but in reality its not a huge difference. I'll definitely be looking mine over to ensure that everything is all good with it before deciding if I will be using it, and like I said I could just run another bead of braze around it to reinforce it. All of this came at a bit of a surprise to me, as well as my wife getting hit in her car the day before, So I am trying to get this built right and make sure it will last but I'm also trying to save as much money as possible doing so.

06silvarubiLGT Posted May 1, 2013 Share Posted May 1, 2013 ^ Its a good thing you can do most of this work yourself. I wish I had someone with the talent/ability to put a shortblock together for me. The labor on them things is pushing it outta my budget. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Yeah I think the assembly savings for me is going to be huge. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 Just got a quote from the machine shop for around $600 for everything. Bore/hone, crank polish, head rebuild and fix a turbo bracket boss on one head. I don't feel that bad anymore, I was expecting closer to 1k for all of that work.

06silvarubiLGT Posted May 1, 2013 Share Posted May 1, 2013 yea thats cheap I was qouted $600 on head refinish alone, the parts are small and dont take alot of work to refinish.. How many miles on that crank? A new ones only 350ish and thats a forged one Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 1, 2013 Author Share Posted May 1, 2013 150k on the crank... I don't think I need a forged one since I'm not going to add anymore to this, I actually might tone the boost down a bit... I just wanted the forged pistons so I can bury this common problem.

06silvarubiLGT Posted May 1, 2013 Share Posted May 1, 2013 Ive read that these cranks have a tendency to warp slightly with high miles, thats why I was asking, they all come heat treated now, so anything new is forged, just and added bonus Link to comment Share on other sites More sharing options...
Max Capacity Posted May 1, 2013 Share Posted May 1, 2013 That's a great price from the machine shop. Valve's may be extra if you need them. My machine shop bill was reasonable too for all I had them do. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

I also have different pistons which I thought was done to prevent this failure, but possibly not, so who knows really. Link to comment Share on other sites More sharing options...
B-BGTLimited Posted May 2, 2013 Author Share Posted May 2, 2013 Well its all apart and in the back of the Jimmy... Heads block crank and rods all going to the machine shop tonight. http://i257.photobucket.com/albums/hh201/3400modified/Leggy/FB_IMG_13674492056279085_zpsb892562b.jpg I don't know how this thing can hold as much power as it does... Look at the size of this crank! thats a 3/8 inch/lb torque wrench next to it... 120-960in/lb range on the wrench for reference. I feel like I took apart a Briggs motor! Also picking up some sort of oil pickup tube.. my screen has piston parts wedged in the edges of it way inside that I can't get out... I do not need that stuff falling free later in life... Time to replace it. I'm also glad I did NOT ever remove the banjo bolt filter so that may have saved my turbo from any debris in the oil after the regular filter, but seeing how the oil is pumped from the sump to the main filter I doubt it would have done anything anyways.

Max Capacity Posted May 2, 2013 Share Posted May 2, 2013 Can't remember, did you say your getting a new oil pump too ? Does the oil go thru the oil cooler before the or after the filter ? I believe you can take the oil pump apart and check the inside ? I ordered my oil pump from Mike at AZP, just told him to send what he would use on my set up. I don't know which pump he sent me, I trust him. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
