Engine knock of death!

Ok, so I just bought a new 5th gen for super cheap. Apparently it had a slight engine knock and was not driven after the original owner heard it. He took off the oil pan to discover the the rod bearings were a lil damaged. Now I'm under the car looking at the cam and whatnot, there is a small notch carved out(see below) but everything else seems pretty smooth and unaffected. Theres no real way for me to feel the entire crank to prove this. So my question is in regards to the deformation that I'm seeing, If I just give it new rod bearings the same issue will pop up again I'm thinking but I do not want to remove the engine. Any definite solutions to this?

The spot thats not so smooth.

Re: Engine knock of death!

Ouch man, I am taking my newly rebuilt motor apart hoping that this is the case rather than something worse... But the only way to really fix it would be take out the crank and have it machined.

Re: Engine knock of death!

If your fingernail gets caught in those scratch then it'll need work to be done with it. I mean, if it's not too severe, you can use a scotch brite pad to smoothen it out but don't quote that on me though. GL!

Yeah, from what I've read up thats the best option.

Its more like an indention than gouge. Nothing rough or jagged just not completely smooth. If I did happen to smooth that out I'm sure theres something else not so smooth that I can't see or feel.

Is there any way to rotate the camshaft(<-wrong! meant to say crankshaft) and not turn on the car so I can inspect it better?

What you mean is you don't want to turn the bottomend over right?

You can turn the whole engine over by using a 19mm socket with a extension and a breaker bar so you can inspect the rest of the crank. The only way I can think of about the turning just the cams is to take off the t-belt to be able to do so.

Yes, first off I need to correct you it is the Crankshaft. You threw me off in the beginning when you said camshaft. The camshaft is on the top of the motor, the crankshaft is at the bottom. Now to rotate the crankshaft, you need to turn the crank pully. that is located on the driver side. There will be an opening in the wheel well. I think it is a 19m socket. So get a bunch of extensions and turn the bolt counterclockwise and it will rotate the crankshaft.

Re: Engine knock of death!

yeah there is a little hole in the fender lining on the driver side. a 1/2" drive socket with an extension and 19mm socket will turn it

Re: Engine knock of death!

Thanks for the info everybody, and yes I'm a moron crank not cam. Anyways I just got some emery paper(cloth sandpaper) to smooth out those rough spots once I find em. Pastic gauge to check and see if I'll need oversized bearings after I'm done and I'm in the process of looking for a new oil filter. Actually getting the sanding done seems to be the most difficult thing that comes to mind right now.

Re: Engine knock of death!

Just make sure there's no leftover abrasions from the sanding. Clean it with hot soapy water then use engine assembly lube after you have cleaned and plastigauge it.

Engine lube! Thats what I forgot to get. Thanks for the reminder. I'm hoping that 120 grit is enough to get the job done.

I think 120grit is a bit too rough?? I don't know maybe I'm just being dumb.

180 may have been a better option but it wasn't available. I could have got 320 but thats such a fine grit I wouldn't have been able to sand anything.
