For the love of God man.. That's just ridiculous. Engine still running smooth though?

COSMO · 09-16-2014, 06:36 PM

So far so good but like I said only time will tell..

Get oil analysis done for every oil change. Metal shavings in oil pan = start of something bad, but I really hope I am wrong.

Send the oil to Blackstone. You at least want to know what trace metals are showing up. It'll tell you if it's normal or signs of something you should be concerned with. Just write the details on the slip and they will take it into account during their analysis

A new motor is expected to have fine metal shavings, now when I do the next oil change and there is even more than I know that isnt normal..

COSMO · 09-16-2014, 07:51 PM

The new rings on the pistons are microscopically shaving as the rings heat up and form a seal to the cylinder. You can not possibly accomplish that with no metal making it to your oil.

Here is a pic of the magnetic drain plug. Also they did not do a 30 mile oil change after the dyno tune, bobby just confirmed..

COSMO · 09-16-2014, 08:05 PM

sorry for the crappy pics..

That is not too bad on the magnet. It's hard to see though. The camera focused on the bolt, not the junk.

I would cut the oil filter apart and see what it looks like.

That is a lot of metal... I have built several engines, and yes a little bit of shavings are normal, but that seems to be excessive to me. It may be possible too that they just did a poor job when building it as far as cleanliness goes... Just my opinion from past experience. I really hope I am wrong though. If you see ANY next time you change your oil, I would say there is definitely a problem. Hope for the best!

I really hope that's just things breaking in and not breaking apart :/ You've been thought enough as is

This may be the wrong section to ask this question but I finally had a chance to install my new 305/30/19's and the handling on the rear is horrible. It feels as if the rear is loose with a lot of sway. The front tire size is 245/40.. At this point I kinda wish I would have the on the 285/35's.. Any thoughts or suggestions?

they probably left your rear suspension loose, had to take it off to get the steering rack brace off lol. (I kid, if the tire is too ballooned you will have increased tracking error which gets worse with a softer sidewall tire)
