cal_look_zero Posted March 11, 2012 Share Posted March 11, 2012 Rod bearings were disintegrated. Wondering if the crank/rods are even salvageable at this point? I'm going to split my other block soon, but it felt just as crunchy NOT HAPPY. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted March 11, 2012 Share Posted March 11, 2012 well there's your problem! Link to comment Share on other sites More sharing options...
Fairtax4me Posted March 11, 2012 Share Posted March 11, 2012 Is this the one that had the oil pressure light on? ( I might be thinking of the wrong person) The crank can probably be undersized and reused with the proper size bearings. Take ot to a machine shop and ask what they would do. Sometimes it can just be polished out and be fine. Might be cheaper to get a good used crank though. Link to comment Share on other sites More sharing options...

cal_look_zero Posted March 11, 2012 Author Share Posted March 11, 2012 This is one of 2 EJ25D core engines I got on CL for $150. I'm fighting the other one hard trying to get it disassembled. Don't know any history on either engine, but this one was the more crunchy/binding of the 2. Link to comment Share on other sites More sharing options...
cal_look_zero Posted March 11, 2012 Author Share Posted March 11, 2012 Well this one is thrashed too. Between the 2 though, I should have a good engine after I find out if either crank can be saved and/or buy a good crank. Anyone have a good 2.5 crank? The second engine completely lost the #3 rod bearing and beat the hell out of the case. Probably salvageable, but the first case was nearly perfect. Going to definitely be a hodge podge like everything else, lol. Link to comment Share on other sites More sharing options...

I bet the damage is over .050 deep. it took a couple times looking at that pic to notice the bearing on the left... looks pretty bad. good luck with the project.

987687 Posted March 11, 2012 Share Posted March 11, 2012 Yikes! That's no good When I tear down my 25D, that's now what I'm expecting to see. Rockauto has a 25D crankshaft for $205 with a core charge of $100. Might be worth it if yours is beyond machining. Link to comment Share on other sites More sharing options...

I'll be taking both cranks, the bad case, and all the rods down to the machine shop. May be welding up some cool garage art out of all the destroyed goods.

jarl Posted March 12, 2012 Share Posted March 12, 2012 Did you check the camshafts? The shiny stuff has the bad habit of traveling all around the engine... Link to comment Share on other sites More sharing options...
cal_look_zero Posted March 12, 2012 Author Share Posted March 12, 2012 Did you check the camshafts? The shiny stuff has the bad habit of traveling all around the engine... One set of heads/cams had some scarring. The other looks like it was a quick painful death from the sump getting punctured, and the heads are pristine.

Robert Harik Posted March 12, 2012 Share Posted March 12, 2012 (edited) I use to grind cranks many moons ago ,and sometimes on very expensive cranks (tractors) customers would have journals welded back up to try and save the crank. But it seemed more often than not it would warp the crank so badly that it was not usable( or there would be to many inclusions in the weld). Is this a common / reliable method now? Did some reading online , and apparently if done right , it works well. Edited March 12, 2012 by Robert Harik Link to comment Share on other sites More sharing options...
