hi since fri I have developed a nasty rattle



i will be doing a b18 swap but curious to what it can be?
also any possible damage to the head? I have had the valve cover off and all the valve are moving freely didn't feel like it was missing just lost power and noisy as hell,

not had chance to get head off with it raining,

if it matters the knock sensor is faulty and was running a p73 ecu with itr cams and was in 4th @ 8000rpm when I lost power
 
Well got the head off and ir seems like the big end on cylinder1 is at fault, got movement up and down, will have some pics when I get rest of it out,
 
Me too if the rain holds off today should be out tonight, bearing in Mind at the moment at my new house I only have a 3/8 socket set no engine lift
Also the piston has marked the head slightly on the combustion chamber luckily missed the valves

What happened, what did you do to it?
 
Thats some noise for a bottom end, sounds like its running without a manifold an thats really loud !!
 
not had chance to get the block out but it does seem like I've spun a big end as have also found bits of copper in the oil ways in the head and the vtec solenoid
was lucky imo as was at 8000rpm when lost power
will have a pic or another video up later on
I just wanted another week from this engine
