psu_Crash Posted July 24, 2011 Report Share Posted July 24, 2011 (edited) Thought it was just a head gasket.... Surprised to find that in mostly one pieceSo what went so terribly wrong here? Just the abuse of learning MS finally catching up to me? The head doesn't look too bad. I'll get some pics once it's cleaned up. FWIW compression tested 127psi across the board not 25 miles before this came to light. All of these are exhaust side. Intake side looks fine http://img841.imageshack.us/img841/834/20110724155605.jpg http://img217.imageshack.us/img217/1999/20110724155658.jpg http://img34.imageshack.us/img34/9992/20110724162451.jpg http://img30.imageshack.us/img30/2561/20110724162610.jpg http://img4.imageshack.us/img4/1650/20110724162642.jpg http://img16.imageshack.us/img16/7162/20110724162756.jpg Edited July 24, 2011 by psu_Crash Link to comment Share on other sites More sharing options...
polarisman14 Posted July 24, 2011 Report Share Posted July 24, 2011 Wonder what the hell caused that? Remember, it could always be worse...I wish I was in your situation right now because at least that meant I got to drive an MPI Starion for a while and enjoy it...All mine does is crank over and occasionally sputter.

ESIrType? Posted July 24, 2011 Report Share Posted July 24, 2011 MLS head gasket? I one had issues with the head lifting at 18psi with ARP head studs and a FelPro gasket. I changed to a MLS gasket and used copper spray and had no issues of the head lifting at 20psi. I pulled the head off to put the new one on and the head, block and gasket looked great with no leaking.That's pretty nasty it went into the block. Good luck,Shawn Link to comment Share on other sites More sharing options...
psu_Crash Posted July 24, 2011 Author Report Share Posted July 24, 2011 Oil looked like a milkshake... It was an Ajusa gasket with the arps at 90 ft/lbs. I've been running the Holset into low 20's recently and also wonder about it lifting. I know others have run the this setup well into the 25 psi range without issues. Yeah polarisman it's been a good time the last 2 years. My luck was bound to run out eventually I suppose Link to comment Share on other sites More sharing options...
polarisman14 Posted July 24, 2011 Report Share Posted July 24, 2011 Did you use the Moly lube ARP suggests? If not then it's not an accurate torque number. Link to comment Share on other sites More sharing options...

rosengrant826 Posted July 24, 2011 Report Share Posted July 24, 2011 Looks like you got a lot of crack there son. Better have this ready for the 20th. Link to comment Share on other sites More sharing options...
Funky Phil Posted July 24, 2011 Report Share Posted July 24, 2011 (edited) This is the 3rd or 4th block Ive seen do this. Originally thought it was from over torquing the ARP's but who knows..... You can definitely tell it was leaking cyl pressure on the exhaust side. But these were all on pretty aggressive setups. What kind of timing advance were you running? Cam and exhaust manifold? AFR's?

psu_Crash Posted July 24, 2011 Author Report Share Posted July 24, 2011 (edited) 20 degrees advanced at 20 psi. AFR mid 11s315ml meth/H20 nozzle with 66% methanol 33% distilled Schnieder 284-H CamMy modded exhaust manifold with external gate Last run was made on SMB's manifold It ran like a top last saturday after the SMB install. Brought it back let it idle down and checked things all out. No issues. Go to start it on Monday and when I finally get it to fire .... White smoke everywhere.

serpentkilla Posted July 25, 2011 Report Share Posted July 25, 2011 Mine did the exact same thing, but it was it was a bit worst. The crack went all the way to the no 4 piston. That did it for me. I went and got another block, got it bored out to the same size. Took it up to vir, then pulled the motor and sold it. Link to comment Share on other sites More sharing options...

psu_Crash Posted July 26, 2011 Author Report Share Posted July 26, 2011 Thanks for the sympathy guys and gals! I have shown the block or pictures to everyone engine savvy that I know in the past few days looking for some kind of explanation. a little more infoARPs studs were installed hand tightEvery one was still very tight when I loosened them. The car did get hot once last summer @230-240Head and deck were surfaced before this HG installThe coolant line that the Magna has no place for was routed to the bottom of my t-stat housing. The general consensus seems to be heat. Either from overheating at some point, low on coolant, poor flow or maybe high EGTs since it only happened on the exhaust side. Just to name a few theories. Scares the heck out of me to build the new block the same way but I really don't think it was a build error. Very likely user error I am afraid. I still haven't tore the head apart to check it out real good yet. I'm a little nervous about it's condition given the poor shape of the block ...

psu_Crash Posted July 27, 2011 Author Report Share Posted July 27, 2011 The whole 4G64 swap idea keeps going through my head. It bolts up, my ignition/CAS setup is plug and play with it, and parts are everywhere. But I have faith the G54B CAN and SHOULD be able to handle what I want it to do. So the new block and head will be picked up this weekend and let the rebuild beginSeems clear that things got hot for one reason or another so I'm going to try and figure that out ... and cross my fingers Link to comment Share on other sites More sharing options...
StarquestRescue Posted July 27, 2011 Report Share Posted July 27, 2011 This reminds me of my quick weekend short block swap. That turned in to one issues after another. At least it does not look as bad as a local guys block. The cracks took out as least one pistion. This one never made any real power. http://i237.photobucket.com/albums/ff45/StarquestRescue/DSC02382-1.jpg Link to comment Share on other sites More sharing options...
