October 21, 201213 yr 1996 EJ25 dohc 208K when i was replace o-ring of fuel injection... somehow got bad noise... VVVVVVVVVVVVVVVVVVV so, im decide pull out the engine and see nothin damage bore and pinions. VVVVVVVVVVVVVVVVVVV i dont understand why and i dont want put engine on it and get noise again. please help me.
October 21, 201213 yr Rod knock, even when you spin it by hand I hear it. I think. I belieive it is much more common in these engines than any enthusiast would like you to believe. I hope the rebuild market has figured out how to cost-efficiently build thee bottom ends. It's not something I can spend the time learning.
October 21, 201213 yr So what normally causes it? Worn out rod bearings or are the caps stretching? I believe it is normal to reusing rods and caps in rebuilds, with undersize bearings and a crank grind if necessary. Out of round journals are the most likely culprit, IMO. The 2.5 pack quite a punch on a short stroke. Splitting and re-splitting the cases and "plastigage"-ing the journals seems like a half-baked way to rebuild these. It would either take some crazy high tech micrometers or a perfect touch , neither of which I have. With the case bolts threaded into aluminum, the bolt stretch may have to be done merely by expert hand.
October 22, 201213 yr the one making the noise hehehe Don't be so sure. That might be the best one in there.
October 23, 201213 yr Author Just question. if i repair new ONE connecting rod. should be OK with old piston and bearing connecting? before i sell this car.
October 25, 201213 yr It looks like the piston was hitting the bottom of the bore? The piston is damaged, the block is damaged. It's toast. Drop a 2.2 in it and save yourself some trouble.
October 25, 201213 yr I'm not seeing an impact mark. Yes you can replace just the one connecting rod/psiton/bearing assembly.
October 26, 201213 yr Author mmm, Im still dare get one new rod before installed. I need Try to sell it. only used 50miles of Fel-Pro head gasket. old piston and rod's bearing. 96' Ej25 DOHC is old sh*t... you think Ej22 can fit with automatic from Ej25? doubtfully...?
