Well my buddy finished my car up last night. The engine (LT1) was just rebuilt and has about 20 miles on it. He calls me up and tells it was making some noise. He changed the oil because he figured it was just some break-in lube left over that had to come out. When he drained the oil he said there was some metal shavings in it and on the filter. He said it looked goldish like copper. So my question is what does this mean? Do you guys think the engine is junk and will need to be rebuilt again? What do you think is happening in there? We're going to call the engine shop and see what they say, but I thought I'd ask you guys first and try to get an idea of what I'm dealing with here. Thanks.

 

Maybe he is referring to the bearings. Regardless, any metal shavings in the oil is bad news.

I'd be careful with that one. Make your builder rebuild your engine at his expense. Or just have him refund your money....and go somewhere else.

 

Its a rebuilt engine, metal shaving in the first oil changed should be no surprise.

However, if he is hearing a knocking sound get that checked out before you destroy something else.

 

That's right. Break-in 'wears' the metal parts in. Hence the need for an oil change after a short interval.

The sound is not good obviously. Check for loose/mis-adjusted rocker arms and exhaust leaks.

Just to be safe I`d pull the pan and check the rods and mains and see if any bigger piece`s are in the pan! The noise part got me worried!! Good Luck!

 

Well we called the engine shop. They said to change the oil and try driving it. Shortly into the drive we started getting a loud deep knocking in the engine. The shop thinks the engine spun a bearing. It's getting pulled and rebuilt all payed for by the engine shop. Free for me so I can deal with it.

 

When you change your oil pay more attention to the oil filter than whats coming out of the pan.

 

I am going to say you spun a rod(s) bearing. Make sure you fill us in

 

Definetley. They ripped it apart today already so I should know what went wrong shortly.

 

Yep it spun a rod bearing. The shop said they just need to turn the crank, so no major damage. Thanks to memorial day though I have to wait till Tuesday to get the engine back.

 

Are you sure you want them doing the work?

 

my thoughts exactly . would you want to make the same mistake twice?

 

Well other than this incident this guy is a pretty well trusted engine builder. Not to mention my only other option is to have a different shop do it and pay out the *** again for another rebuild. At least this guy's doing it for free. I'll give him one more shot.

 

Well the shop was supposed to call me yesterday...no call. So I called them...no answer. Hopefully they call me or answer today.

 

Well it turned out the crank was bent as well. It was bent by .007". He put a new Scat(sp?) crank in for free and he finished the engine up last night. If all goes well the car should be up and driving today!
