Chocoholic005 Posted September 12, 2020 Share Posted September 12, 2020 These are off a 2014 I believe. The drivers and passenger OCVs are the same part number are they not? Your heads are from a 2014? I had no problem swapping 05 OCVs into an D25 heads, but I couldn't tell you what year they were from. Link to comment Share on other sites More sharing options...
ViscousSquirrel Posted September 12, 2020 Author Share Posted September 12, 2020 The OCVs changed mid year in 2010 but I don’t know if the bore changed or not? Link to comment Share on other sites More sharing options...

ViscousSquirrel Posted September 13, 2020 Author Share Posted September 13, 2020 (edited) Air pump deletes installed. Got the brand new cam gears lightly placed in there, soon to be, new home with new bolts. I really wasn't expecting to have to buy 4 new cam gears Edited September 13, 2020 by ViscousSquirrel Link to comment Share on other sites More sharing options...
ViscousSquirrel Posted September 13, 2020 Author Share Posted September 13, 2020 Got some Company 23 tools in the mail today, still waiting for a few more to be able to do the timing. I put on their vacuum line T while I was at it. Look at that shiny new piston peaking out through the head and valve cover. Link to comment Share on other sites More sharing options...
ViscousSquirrel Posted September 13, 2020 Author Share Posted September 13, 2020 (edited) Got the intake installed today. I was going to mount the exhaust but it was pretty corroded. I used a while wheel on a drill as well as block sanding to get them to this point but the down pipe flange is looking like a lost cause. The head shields are 170k miles of "rust welded" in place by the exhaust bolts and I can't get in there to really block sand the flange. Any have any ideas on the usability of these headers given the condition of the DP flange? I ordered a 2014 WRX Oil Control Valve to see if maybe that will fit in the other head.

Max Capacity Posted September 13, 2020 Share Posted September 13, 2020 I put red RTV on the DP gasket let it tack up for 15 minutes, lay it on the DP, put more red RTV on the other side of the gasket, let it tack up then put them together. Your sure thats the Dp flange...looks like the up pipe flange on the manifold...? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

Your sure thats the Dp flange...looks like the up pipe flange on the manifold...? Yeah... I was thinking the red RTV route might work as well but I REALLY don't want to go that way... . Yeah it's the downpipe flange on the exhaust manifold that bolts to the downpipe coming from the turbo. Link to comment Share on other sites More sharing options...
Tehnation Posted September 13, 2020 Share Posted September 13, 2020 I think you are overthinking it big time. It's the exhaust, that's why they have thicker gaskets. The gasket will eat up all the discrepancies! Sealant on the uppipe? Wait there is some confusing terminology going around. The picture you showed is the end of the header which connects to the uppipe, the downpipe is the back of the turbo. At no point would I use sealant on either. The turbo is in between the downpipe and uppipe, pipe between the exhaust manifold and turbo is the uppipe and the pipe after the turbo leading to exhaust is the downpipe. Uppipe meaning its the upstream, the pressure which moves the turbine, and the downpipe is the downstream or final exhaust. Link to comment Share on other sites More sharing options...
Tehnation Posted September 13, 2020 Share Posted September 13, 2020 Also Grimmspeed makes a double thick gaskets if you need a thicker one to eat up any extra space. Link to comment Share on other sites More sharing options...
Tehnation Posted September 13, 2020 Share Posted September 13, 2020 (edited) The exhaust side of turbo is solid metal, if you need some type of sealant between the downpipe and turbo something is wrong, the exhaust is a physically bolted and stabilized system, there is no slack, why would you need sealant, no way are the surfaces that bad where the gasket can't compensate, if so you shouldn't use that part. I can understand maybe some copper crap like the stuff on o2 sensors but sealant doesn't make sense to me, the exhaust pressure isn't enough to need sealant imo.

Tehnation Posted September 13, 2020 Share Posted September 13, 2020 Wait.... why didn't you sand the flange when the motor was out?? Why exactly can't you get in there? I am soooo confused..... Link to comment Share on other sites More sharing options...
Tehnation Posted September 13, 2020 Share Posted September 13, 2020 Yeah it's the downpipe flange on the exhaust manifold that bolts to the downpipe coming from the turbo. Downpipe doesn't connect to exhaust manifold, that's what's confusing me! I don't understand this sentence lol, something is wrong with it. Exhaust manifold -> uppipe -> turbo -> downpipe.

ViscousSquirrel Posted September 14, 2020 Author Share Posted September 14, 2020 Well, a friend is sending me a set of factory manifolds with good mating surfaces so I can put my exhaust issues to bed. I am really not a fan of headers on street cars. I picked some new Grimmspeed gaskets and I grabbed the double thick one that hopefully will prevent a leak from the factory manifold to the aftermarket catless uppipe. Thanks for the tip on the thick gaskets BTW, I appreciate it. Link to comment Share on other sites More sharing options...

Max Capacity Posted September 14, 2020 Share Posted September 14, 2020 Is that a thrashed Banjo bolt next to the heat shield? What's the story on that, it looks gruesome? No those are just the nuts and bolts from the heatshield and or dp to turbo. That is the bracket that mounts to the top two turbo/dp bolts that holds the heatshield. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

ViscousSquirrel Posted September 15, 2020 Author Share Posted September 15, 2020 Benny did not know the answer on the Oil Control Valves, as afar as the differences between the changeover in 2010 is concerned. So I suppose I'll find out here shortly when the new one shows up. Link to comment Share on other sites More sharing options...
timmie415 Posted November 10, 2020 Share Posted November 10, 2020 Thanks for the detailed parts descriptions ViscousSguirrel. My long block is at the shop and this rebuild thread is going to help me a ton when it gets back. Also inspiration on which hoses I want to replace while I am at it.
