06 Knocking noise and burning oil
I have an 06 Rubicon and there is a knocking noise. My guess would be the main crank bearings so I tried to look them up and it looks like you can't buy just bearings, you have to buy the whole crankshaft and rod assembely... WOW $400!!!
Is there any way around this? Also Its a loud knocking noise and it sounds like it is coming from the bottom. I haven't adjusted the valves yet so I need to try that but am pretty sure that the noise is not the valves. The valves are more of a ticking noise. Another problem with it is it smokes pretty good. If I rev it up to about 3/4 throttle it will not burn anymore and run clean. Then if I rev it down to about half throttle it will sputter like its miss firing and start burning oil again. Then when I rev it up more it will clear out. Could it all just maybe valves? It has 1xx hrs on it so not that many... Any help would be great. Thanks |

i haven't heard of many crank bearings going out i would say check the timing chain/tensioner the valves would make alittle noise but not a whole lot as far as the smoking goes bad rings/ scared cylinder

Knocking may be bearings. Not sure. You can purchase bearings seperate. Smoking may be rings, like FloatingForeman said. Here is a link to show what you have....

that does sound like a rod bearing i couldnt tell you for sure without seeing it. it could also just need a new timing chain. but once agin not for sure. butif it is a rod bearing you really need to replace the crank and rod too unfortunately

Let me know what ya get I've had a loud ass ticking metallic noise coming from my top end I'm leaning towards a loose timing chain slapping because when it gets a little higher in the RPM range it seems to go away

Does anyone know if there is a "special" honda tool I'm going to need to remove the tensioner or the chain itself, in my book it shows a tensioner stop tool, is that something I can get off the shelf somewhere around here ??
