I have a 97 honda civic lx 5 speed motor locked up and am curious if a motor from a 98 will bolt up with no issues

 

Yes the USDM long blocks are the same.

 

Hi i have a similar question. I have a 97 vtec lx 5 speed the motor blew so i had a 2000 non vtec auto motor to use to replace mine i swapped over everything off of mine onto to 2000 motor . ( trans, intake mani, exhaust headers, distributor, alternator, stater, ) u get the picture i swapped everything from mine to the 2000 block i didnt put my vtec heads on right away i ran it non vtec for bout a week. I finally put my vtec heads on and upon starting it the idle was horriable and wouldnt stay running unless i had my foot on the pedel. So after cleaning my iacv replacing my plugs rotor and knock and o2 sensors it fianlly stays running but the idel is still very rough and the car is running like crap pls someone help in out of ideas and rdy to junk the car!

 

Sounds like your ignition timing is bad, has happened to me a few times after a head swap for obvious reasons. Also, make sure your timing belt is in time.

I'm certain it's ignition timing. Get in there with the timing light.

well spaceturtle917 theres no need to do any timing work or anything besides swap out another motor yet agin cus today while driving the car suddenly shut off and wouldnt start back up so i was gonna do the timing once i took my valve cover off i noticed a milky film ( water in my oil) so i procceded to take everything off to check out my head gasket thinking maybe it moved when putting it on before well needless to say i need a new motor yet again im including some pics so u guys can see what happened and ill include some of the first motor that blew up also
