Is the noise coming from the bottom of the enigne more than the top?

I'm not a 100% sure on this but my guess would be from what your saying its probalby a spun bearing..

yup it seems t be comming from the bottom and spun bearing is what I figured it was. Is it worth to fix or just replace? I got a d15y7 block in storage. I wonder how well it would do with my d16y8(current motor) head and some turbo.

why do you think the engine is blown?


I re-read the post, I thought you had a single knock at 2,500 and that was it.

if it sounds like a loud valve tap then I would concur, spun bearing.

 

to fix or to replace.. that is the question. I will be doing all the work.

 

If you already have it in storage why spend money on machine work and all of that if your main concirn is to just get the car to a good runing condition..
I would say just drop the other block in and worry about fixing or building up the other one later on...
