ok so i loan my car to my buddy for a month and he calls me one night saying that something happened to my car so next day i went to where he left my car (of the side of the road) had popped the hood and had him start it and found that it starts but have a very loud knocking noise and the motor was rocking alittle bit. i checked the plugs and there was some detonation and checked the oil and it was low.
Any inputs of what mite of happened???

A number of things could have happened, but it sounds like a blown/shot piston. Shut that bitch down and don't try starting it till you tear it apart unless you want a piston melted to the side of the block or something similiar. Don't forget to tell your friend thanks for blowing your motor....

How low was the oil? If it was low enough, engine could have died of oil starvation...

Jdm240sx123 · 05-26-2011, 01:39 AM

Regardless your homie should of been on top of that.... Agreed???

Let you buddy know that your engine was destroyed in his hands and after that you have to make the call on weather or not he's going to get you a new motor or if your going to bite the bullet.

Maybe a rocker arm jumped off?

camaro379ss · 05-26-2011, 07:37 PM

Your buddy should be responsible for the fix regardless because they were not being a responsible driver.

Now me and the mad scientist gotta rip apart the block to replace the piston rings you fried.

Umm? Did you quote the 16 year old dude? Word for word...almost?

Brian BK · 05-27-2011, 07:46 AM

I'd say most likely he spun one or more rod bearings. Sr's like doing that, so if the oil was low that probably exacerbated the problem even more. Why did you loan him the car? Clearly you had something else to drive, so why give him the 240 with an engine swap? Did you tell him to check the oil every few days, and was he familiar enough with cars in general to spot a small issue before it turned into a bigger problem? If not, then it's hard to say what to do. If so, then he should man up and pay for the damages.

Brian BK · 05-29-2011, 08:47 AM

yeah found out it was a spun bearing.... ya i loan it to him being that good friend and this is how he repaid me... its ok though cause i ended up buy a s14 with a rb swap. so know im just going to end up parting it out and try to make some extra cash.

*fliprayzin240sx* · 05-30-2011, 11:14 AM

If its an S14 chassis...send me a PM...
