Prelude Problem
 

Ok my friend has an 89 prelude si, and he snapped the timing belt. He threw a new one on but it runs like ---- and we figure it bent a valve or 2. My question is can he get a head off any B-series engine since it's a B20a5? Or does he have to get a head off of another B20a5..

Re: Prelude Problem
 

if im thinkin right, its not compatable with other b series, that b series is in its own boat, kinda like the jdm b20 accord motor.

Re: Prelude Problem
 

I think that motor is a bastard, he needs a head off, the same thing.

on an other note, are you sure yall did the belt right

Re: Prelude Problem
 

Like it may have "Crank Walked" DSM style on you and be out of time. I think you'd have serious issues with bent/broken valves.

Re: Prelude Problem
 

yeah but would a snapped timing belt cause crank walk? Yeah i was wondering if his B was similar to the older DOHC D motors and how they're different from the newer SOHC D's. I'm pretty sure he did everything right cause my other friend was talking to him about it and he's done at least 10 timing belts....

Re: Prelude Problem
 

lol nice reference to something that has nothing to do with this...

Re: Prelude Problem
 

If I'm not mistaken the crank rotates and the belt breaks and thusly now the camshaft(s) rotate at differant rates then the crank itself. Now - out of time. See though, when that usually happened on DSMs they had SERIOUS problems. Broken valves in the cylinder. :-X Hmmm, sounds more out of time, and I doubt crank walk because from what I have heard/learned crank walk is NO JOKE.

Re: Prelude Problem
 

i thought crank walk was horizontal play of the crank moving back and fourth... guess i was mistaken?

Josh, shut up.

Re: Prelude Problem
 

you are mistaken...this is way off topic but i figured id let you know.
