bofronado Posted September 30, 2015 Share Posted September 30, 2015 I have a 1998 2.5 GT the had a spun bearing on a connecting rod and I am trying to find a replacement. My question is what other years of 2.5 engines would have the same connecting rods? Not having a lot of luck finding fit information. Link to comment Share on other sites More sharing options...
monkeyposeur Posted September 30, 2015 Share Posted September 30, 2015 Look at this diagram on opposedforces.com: http://opposedforces.com/parts/legacy/us_b11/type_22/engine/piston_and_crankshaft/illustration_2/ It shows part no. 12100aa130 or alternate part no. 12100aa131 being the same from '97-'99. You can always call a dealership parts counter to confirm. Link to comment Share on other sites More sharing options...
Osei Posted October 1, 2015 Share Posted October 1, 2015 If it's spun, then by the time the rod side is polished, the original size may not fit. You won't know until it's done. Unless you have nothing but time, it's less labor to swap a 2.2 in it. Doing the necessary t belt, idlers, separator plate and retightening of the oil pump screws while it's out. O.

bofronado Posted October 1, 2015 Author Share Posted October 1, 2015 Thanks everyone for the input. I ended up just ordering a new one from the dealership. I already had ordered a remanufactured crank because it was obvious the rod bearing was gone on the one cylinder. Link to comment Share on other sites More sharing options...
elislider Posted October 8, 2015 Share Posted October 8, 2015 FYI these motors are old and generally cheap to come by in decent used condition. you probably could have found another block used for the cost of a crank + rod Link to comment Share on other sites More sharing options...
bofronado Posted October 16, 2015 Author Share Posted October 16, 2015 okay, I got the engine back together and back in, but now it will not start. Turns over fine, and I checked the spark with a tester that lays on the plug wires and that seems fine, which leads me to fuel. Do I need to bleed the fuel system somehow? The tank indicated that it was empty, but I put a couple gallons in and still not starting. It started okay before I pulled the engine. I have looked at all the electrical connections, and I think they are are hooked up, and in the right place. Any suggestions? Link to comment Share on other sites More sharing options...
Osei Posted October 16, 2015 Share Posted October 16, 2015 Check the large hose from the IAC to the air intake. O, Link to comment Share on other sites More sharing options...
bofronado Posted October 16, 2015 Author Share Posted October 16, 2015 Check the large hose from the IAC to the air intake. O, Nope, it is hooked up. I did pull a plug this morning and it was completely dry, so fuel looks to be the issue. I pulled the line from the fuel filter and there is definitely fuel getting there. Is there a voltmeter test I can do for the wires to the injectors? Link to comment Share on other sites More sharing options...
RustyRuu Posted October 16, 2015 Share Posted October 16, 2015 look up light noid test. (not for our cars but the process is the same. http://troubleshootmyvehicle.com/gm/2.2L/fuel-injector-noid-light-test-1 and read this: (not for our cars but all the testing is the same) http://troubleshootmyvehicle.com/gm/2.2L/fuel-injector-resistance-test-1 use the Ohms mode on the multi meter and it will help you out. to be sure its fuel related first try using carb cleaner or starter fluid and spraying it down your intake manifold. ive even used brake clean and or let a propane torch leak down into it. so then if it almost starts or does start you know for sure. maybe check the psi before and after your fuel filter first.

monkeyposeur Posted October 16, 2015 Share Posted October 16, 2015 Check your cam and crank sensors again as well as your maf, basically all electrical connections. Link to comment Share on other sites More sharing options...

Okay, I did the starting fluid thing and it started right away, so definitely a fuel issue. I can not hear the fuel pump running, but I don't have anyone to turn the key on for me so I can listen at the gas cap. I did pull the return fuel line, ( the medium sized one with the clamp on it) and there was no gas coming out of it, which I would expect, unless I don't understand the system. I did check for voltage at the injectors with the key on, and got volts. Does anyone know where the fuel relay is at? I looked online and there were several conflicting suggestions.

bofronado Posted October 17, 2015 Author Share Posted October 17, 2015 Okay, thank you for all the input. Despite labelling the fuel lines I somehow got the input and output lines reversed. Started right up after that. Knew it was something stupid because it started right up with the totally messed up bearings. Link to comment Share on other sites More sharing options...
