ok picked up a shell with a running ls swap needed a head gasket though. now i had no proof that it was a running engine, so we fired it up with no running gear attached.like coolant, axles, transmission oil and so forth.anyway for the breif few seconds that we ran it it had a grumbling noise.is this because we had no axles in it, also the trans was in a gear,so the diff was spinning. before anyone asks yes we put motor oil in.....plz if u have experienced this lmk

 

No idea what you did, no information on the car or anything else?

 

its a 97 civic hatch b18a motor with gsr trans. put the swap in the car started it and the trans was making a weird noise like if the input shaft bearing was bad. but the throw out bearing is good input shaftbearing is good. turned it on in gear no axles put on, and it made that noise

 

was the half shaft in at the time ? is everything tight/bolted up ?

 

halfshaft was in only and i talked to the two previous owners they both said they never heard any noises tomorrow i will put the other axles in and see what i have then

 

do that and make sure everything is bolted up tight/to spec

 

^ yes i wasnt 100% sure it was gonna run so why prepare it to drive if i would have to drain everything and pull everything again

 

Was there gear oil in the trans?

 

Why wouldnt you have oil in the tranny?

 

wasnt gear oil in for first start, but after we heard the noise we said its gotta be because of the gear oil but we put honda mtf in and it still made the noise

 

so you put the transmission into gear with no lubrication? And now it is damaged?

 

i doubt that it is damaged ppl have driven manual transmission without oil in them, im just wondering if it was the diff spinning making all the noise i didnt get to start it today, i put both axles in and the shift linkage today so next time i start it it will be in neutral

 

it was the diff spinning making the noise transmission is still good
