Max Capacity Posted October 21, 2014 Share Posted October 21, 2014 It's pretty common for these to have burnt valves.

MrTris Posted October 21, 2014 Share Posted October 21, 2014 If you redo the whole valvetrain, you could upgrade to beehive springs (GSC) and such, and see an 8k redline. Link to comment Share on other sites More sharing options...

AMileHighLGT Posted October 21, 2014 Author Share Posted October 21, 2014 Afraid to sit down and do the ciphering, but I'm pretty sure I'm easily over what I thought I would spend by $700-800 Link to comment Share on other sites More sharing options...

I added up my rebuild and stopped when I got depressed (somewhere near the 7k mark).. Link to comment Share on other sites More sharing options...
AMileHighLGT Posted October 21, 2014 Author Share Posted October 21, 2014 The 7-800 isn't counting the rebuild on the heads either. Link to comment Share on other sites More sharing options...

AMileHighLGT Posted October 23, 2014 Author Share Posted October 23, 2014 If it were up to me, the valve springs would be upgraded, I would have that 8k redline, 272 cams, and a larger turbo that breathes well up top... CFO would say no. Link to comment Share on other sites More sharing options...
MrTris Posted October 23, 2014 Share Posted October 23, 2014 Also $800 are the Tomei Poncams. Comes in 252 and doesn't need new valve train.. In retrospect, I would have bought cams, too. Link to comment Share on other sites More sharing options...
AMileHighLGT Posted November 12, 2014 Author Share Posted November 12, 2014 Well. lack of updates lately, sorry. I got my heads back one week ago, spent a little bit of time with the engine this past weekend, ended up breaking the small, curved portion of pcv hose that connects to the large port on the block, so at that point i am done until i acquire that hose, which by the way was damn near impossible to locate the part number. Finally found it yesterday, without the help of our oh so helpful dealer here in denver. Its too damn cold to be working on it this week, the high temp for today, is fkn cold, 10* if were lucky. Inside the shop this morning its a balmy 42* and thats with all the furnaces cranked. Supposed to warm up this weekend, will work then. Link to comment Share on other sites More sharing options...
MrTris Posted November 12, 2014 Share Posted November 12, 2014 Lookin' good! Why are those cams not greased? Needs lube! Lots of it! Link to comment Share on other sites More sharing options...
AMileHighLGT Posted November 12, 2014 Author Share Posted November 12, 2014 Well rhe machine shop has some applied on the cam journals. Seeing as how I need to pull the cams to bolt the heads back on, they will be liberally greased with assembly lubricant at that time. Link to comment Share on other sites More sharing options...

fahr_side Posted November 18, 2014 Share Posted November 18, 2014 While there is still time, buy a set of ARP head studs. It sucks having to pull the engine again because a head gasket leaks. It's not so much the probability of it happening, but the pain in the ass to fix it.

It sucks having to pull the engine again because a head gasket leaks. It's not so much the probability of it happening, but the pain in the ass to fix it. I have them ordered, waiting on their arrival.. Really didnt want to spend another $180 on this project, but at this point I have no effing choice. On Sunday I went to assemble the engine, was planning on entirely assembled. However, i went to bolt my heads on, got through the first step in torquing the NEW head bolts, no problem, 30 ft/lbs. Step two was 70.1 ft/lbs. First bolt got nowhere near 'tight' enough, at least it never felt that way. Damn thing snapped on me. Sheared the bolt maybe 1/4" into the threads. It is sitting in the block still, recessed about 1.5" in the bolt hole. Needless to say, my old ass snap on torque wrench is now shit. Bought a new torque wrench on monday from snapon, also purchased a damn expensive bolt extractor with guides, hopefully the remainder in the block comes out nice and easy, so this is my weekend project. If all goes well, i hope and pray, and maybe even cry a little to get this thing wrapped up next weekend over the 4 day holiday. Link to comment Share on other sites More sharing options...

AMileHighLGT Posted November 23, 2014 Author Share Posted November 23, 2014 This is extractor set just saved my ass a headache. The centering guides made this extraction take less than 10 min. Head studs shipped, eta is Wednesday. Link to comment Share on other sites More sharing options...
Max Capacity Posted November 24, 2014 Share Posted November 24, 2014 So you had some compression on the head gasket...you might want to replace that them or at least that one. Do every thing you can to make sure the threads in the block are clean. The studs should thread in and bottom out by hand. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
