so i was driving in the city and next thing i know 3 clanks and a loud bang with a huge cloud of smoke later, there's a hole in my motors crankshaft casing. then i swap the new motor in mind u it only has 85000 miles. 25 miles after the swap a even louder bang and a hole the size of a bagel is in the crankshaft case once again . both wholes are in the front of the motor right next to the header. they both had a whining noise kind of like a super charger before the loud bang. im about to get the new motor being its under warranty. i was wondering does anybody have the slightest clue wat could be wrong here? i really dont wana put the new motor in and have the same issue.

Not sure what's going on, but you may want to shrink your sig before it the ability to have one gets removed...Originally posted by sweet91accord -
who built them and how?
did you have oil?__

motor had oil started right u it was out of 95 accord ex with 85000 miles. my roommate thinks its the headers i think its the ecu.hmm would a 92 with a sohc vtec be a si????? might as well beComment

A stock ECU shouldn't cause a motor to blow, even if it fails, it'd go into limp mode, or the car wouldn't run at all.
A header (only one on an I4) would definitely not cause such failure, unless perhaps a pipe were completely blocked off (you're not running an F22A header on an F22B, are you?)
These motors aren't prone to such failure. Even the POS F22B1 that you had (it's a reliable motor, just worthless for performance). The only common problem on the F and H series motors is the rear main seal (I believe... don't take that for fact). That can come loose and cause complete engine failure due to loss of oil.

the first block i def changed the rear main seal if thats the one behind the flywheelhmm would a 92 with a sohc vtec be a si????? might as well beComment

ok...let me go ahead and say this, we've beat around the bush enough
You MUST list what you have done to these engines...we will NOT assume these were both untouched engines aside from swapping...we MUST know what all was done (and not done) in order to assist further.____Comment

Very true.Originally posted by bcjammerx View Post
For the same thing to fail on both engines, it has to be something... or just a really really lousy coincidence!
What transmission are you running?

92 accord ex with the first motor being a 96 f22b1 and the second being a 95 f22b1 and i used the tranny off of a 91 f22a1 used a zr racing header 60 mm throttle body 10.2mm spark plug wires short ram intake. 2 1/4 cat back with stock muffler and stock cathmm would a 92 with a sohc vtec be a si????? might as well beComment

not trying to be an ass...just trying to figure out what all is going on...how do you drive the car? How often/long do you redline? Do you change your own oil? If so how often and how much do you put in?____Comment
-
well i don red line i shift at 6200 i used to ork for honda so oil changes and wat not i got down pretty pact lol andi couldnt realy get on the second motor i swaped in cause it wouldnt make powerpass 3 and wouldnt rev past 4hmm would a 92 with a sohc vtec be a si????? might as well beComment

6200 is pretty close to redline...f22's don't make power past 5600? so 6k is not necissary.
On a stock cam/crank setup...if done all the time could cause issues...and while that it is true you cannot treat a stock engine so poorly so constantly, these are pretty stout engines and I still suspect something else, but I'm sure it didn't help
I suspect the noise you heard was a rod/crank bearing going out before pop____Comment

i would def agree with the dont make power past56 but the car still pulls pas 56Last edited by accord_creeper; 08-31-2008, 07:07 PM.hmm would a 92 with a sohc vtec be a si????? might as well beComment

sounds like shit is seizing due to lack of oil.Comment
