As many of you know, I've got a reground stock cam in the motor. I installed a magnetic oil pan drain plug in order to be more aware of any metal shavings coming from the motor. Upon changing my oil yesterday, this is the extent of what we found:


Some very small metal bits stuck to the magnetic tip.


Slightly larger shaving.

Is this more metal than should be generated in approximately 4000 miles? Thanks!

when you put in the reground cam, did you fill with cheap oil, run for 5 mins, drain, replace filter, and fill again?

Yessir, and it has probably undergone five or six oil changes since the swap. Maybe it has been more, since we did the swap around Thanksgiving of 2005.

I'm not sure how much metal comes out of a stock motor, if any.

Honestly Ben..I wouldn't worry about that little bit. It could be residual etc. Now if you find a ton when you open that oil filter...then worry. If you find nothing.. consider this as maybe a little that fell in when cleaning the gasket surfaces.

If your that worried, you could install one of these things. You would have to tap a new drain port on your oil pan. Yet, it would let you know when the **** would hit the fan.


Turbine engine chip detector.

Easy circuit to install. The detector, a voltage source, and a light bulb. Ignore the 24Volt specs. Thats used for aircraft electrical systems. 12 volt would work fine because of the 12volt light you would use.
