my engine is a b18c1 and it knocks when i start and rev my engine and it gets louder and knocks more.. does anyone know what the problems is..

 

check your oil level. if its low add, if it continues rod bearings are gone. good time to build your bottom end

 

sounds like a rod knock to me. like cleantegra said time for a new bottom end

 

yea my oil level is good dam i think i do need to build my bottm end then.. hey how does a b18c j-spec for 2100 or 1800

 

not to bad but be sure of what your buying. Only buy engines from reputable dealers. It immpossible to tell the milage on used engines. you could rebuild your bottom end for less than that w/ forged everything

 

Are you sure it's not just valve train noise??? Or is it deeper sounding? But rod bearings are easy to replace, why replace the entire engine when you can get the rod/main bearing codes and replace them w/ factory....

I'd love for you to get a B18C TypeR engine but if you need fuction, then you can save that motor.

a longblock from hmotors costs 1800.

 

yea thanx but imma stay with my a-spec motor.. pepe is right why spend that much on a j-spec stock motor when i can build my gsr for more power.. but thats my thought tho.. thanx guys.. for 1400 i can get racing rods over size pistpons and a bore..

 

Did you even get the'noise' diagnosed???

Bit of a thread hijack but my friend has this loud "putt putt putt" sound too, and it goes up with revs. The only thing is the sound is definitely from the head, almost under the valve cover (not valve tap). Is that still possible if it is a spun bearing?

 

yes, the knock will resonate all the way up thru the head. It will be a deeper sound, unlike a valve tick. Try pulling that spark plug wire off the cylinders one at a time and keep the engine revved until you here the noise go away. That would be the cylinder you can focus on.
