Ijust recently bought a 1994 integra with a rebuilt b18c.(4000) miles on motor) It had been running fine and had hella power for a month. I noticed that over a few weeks it started to lose power. Then one day I was on the freeway doing about 90 going to work, and it started to knock loudly. When I got off, and slowed to turn, I hit the gas and it wouldnt move for about 2 or 3 seconds. It finally kicked in but cut off and would'nt crank. I let it sit overnight and tried to crank it and it was turning over slow, but eventually crunk. STILL KNOCKING!!!! This car was turboed, but i havent got around to putting it back on yet. I thought the problem could be a rod, but I have no idea.....What could this be?????

 

How's your oil level or oil pressure?

sounds like rod bearings to me dude. dont run it anymore , you throw a rod youl hurt the block.

Yep same thing happend to me, spun a rod bearing. Drain the oil and you will see copper metal shavings.

 

If you plan on saving that crankshaft and or your block, you wont start it anymore.

 

i dont think that crank is any good anymore maybe oil pump failure.

 

It will knock "for sure" once the heart stops pumping.
RIP little engine.
Time for a good old tear down i say...
Hopefully there are some re-useable parts.

 

someone might have put it together with oversize bearings in it. or oil pump failure. or simply an idiot torquing the engine together.
