Hey guys,

Ever since i have turbo'd my B16 everytime i change my oil i seem to have metal shavings on the sump plug. The shavings really really small, if i wipe theme onto a rag it just leave a mark and you can not actually see the individual shavings.

Has anyone got any ideas where its coming from ?

 

maybe rod or crank bearings ? ..
rebuilt motor ? .. were bearing clearances checked when the motor was built ?

 

Yeh they were, they was all fine. I have covered around 30,000 miles in the engine though since rebuild. If it was rod or main related would'nt i have known ages ago ?

Here are some pictures...

 

That's no good. Most likely it's bearings. I'd replace them and check your clearances before you cause major damage. New bearings are relatively cheap

 

The bearing clearence were fine when i built it. The only thing i never had done was get the rotating assemby balanced. Could this cause this problem ?

 

Anyone ?
