Glittery Oil
My last two oil changes have shown some "glitter" in the oil. The first time I assumed ( hoped) it was just dirt or something in the catch pan. Last oil change I cleaned the pan out thoroughly before draining the engine. Still had glitter. I checked with a magnet and it seems that the glitter is not magnetic, although it was hard to tell for sure given the oil sort of coated the magnet. The engine has 110k, oil changed every 5k miles with synthetic. Boosted at 12# and not tracked and not really beaten on much. Uses no oil or coolant, plugs are uniformly clean and tan and engine runs well. Tune is pretty conservative but a few degrees of timing hotter than the FM base tune on the Hydra. Data logs show no knocking, so all should be good. Except there's glitter in the oil. Any guesses as as to what is going on? Wouldn't any piston damage to detonation go out the tailpipe? Beating down the valves? VVT head is stock, but I ususally shift before 7k rpm. No valve train noise is evident. Suggestions? Paul |
Send it to Blackstone labs? It's fairly cheap.

Might be bearings. Send a sample to blackstone.
You can also cut open the oil filter and see just how much is in there. |
or just kep driving it till something happens. If you send the oil off and it comes back bad, you are possibly looking at a rebuild. If you drive it and it actually begins to knock, then you know it was a problem and needs to be rebuilt. Its not like you can remedy the situation with magic aditives after a Blackstone analysis. if its dying, its dying.
|
Plan for a while has been to build a new engine to swap in. I probably need to push that forward. A little bit. Maybe turn the boost down a little too. Paul |
Glitter that isn't magnetic makes me think bearings. Run a little thicker oil and keep your fingers crossed. What oil have you been running previously?

Your bearings don't care how much boost your running (within reason and on a safe tune). If it's going to die, it's going to die, better to send it off in a blaze of glory than to send it to it's deathbed prematurely. |

A little gun shy on the build now after reading that you have to calculate bolt stretch, not torque stuff. My last engine build was a small block Chevy about 45 years ago. Maybe a new turbo engine needs a finer touch than I've got. Anyone have a recommendation for a good builder in Northeast or Central Florida? Paul |
What fasteners require measuring bolt stretch? I assembled a bp this winter and didn't see anything that didn't list an actual torque number.
These are simple engines. If you have any prior engine assembly experience then you're more than qualified to do it yourself IMO. |

The rod bolts. Not that they require it, but its the best way to do it. Some might even say its the only proper way to do it. And I agree with them.
You're right, measuring stretch would be best, but If that is what is keeping OP from assembling himself then I feel he should be aware that isn't the only option. |
Mazworx in Orlando is highly competent as an engine builder. The owner is a friend. He also CNC machines SR20 and 2JZ engine blocks out of billet aluminum, lol. He built my engine and Tony Montana's engine.
He built an SR20 motor that makes over 1400whp for a customer, FWIW. http://www.mazworx.com/ |

waste of time^^^

So what's the problem with that?

So....what??? Paul |

Please let me in on the joke....what's wrong with Mobile 1 Synthetic? Or what was it that I wrote that is amusing? As far as "not pushing it" I'm talking about RPM. I find the car is quicker shifting at about 6800 and since I'm on a stock damper and stock head revving over 7k is not only not productive but invitinf oil pump,failure. So....what??? Paul |
M1 has the largest market share of all synthetic oils.......
It shouldn't be surprising that people are commonly running M1 when they destroy a modified engine. |

Cashes in PTO, closes computer, runs out of office to go buy Schaeffer oil.

The Mobil 1 10W30 would be fine in a lightly stressed engine for as long as most original owners have them. The forces we are putting on the engine's narrow bearing surfaces are two, three, or four times as much from the increased power depending upon if you are at 200, 300, or 400whp. The engines weren't factory designed to do it. The viscosity of the T6 being 40%+ more or the Schaeffer being 80% more becomes important quickly. If that film strength does break down under the force you then need extreme pressure (EP) lubricant additives like zinc and phosphorus to continue to protect from metal to metal contact. I also noticed Rotella T4 (EK4) in my searching and though it had a really great additive package and decent visosity it had a 204*C (399*F) flash point, which would preclude me from considering it. Like I said, there are several good oils out there for what we are doing to these little engines. Do your own research and understand why, then find something that you like. TL;DR - Mobil 1 10W30 is too thin and lacks enough additives you want for trubomiatas, imo. |

Keep in mind this is quoting oil viscosity values at 100 C. If you're on track, your oil is hotter, and oils can change a lot in how viscous they get above that. Also, flash point doesn't tell you much, unless you care about oil consumption or ring/bore wear.

This is good information. I imagine that I'm not the only one that thought I was doing the right thing using Mobil 1. Looks like my next oil change will be early and go to a heavier weight. Glad that I never succumbed to the 5W30 and at least stayed with 10W30. Time to research what I'll use instead. Paul |
After reading up some on oil, it looks like Amsoil would be a good choice. Any recommendations on the weight that I should use? Northeast Florida, fifty degrees is cold here and summer is like Florida....in the 90's. 10W40? Help me save my engine until I can get the new one built. FMII @ 12 psi VVT motor with stock internals. Good cooling and conservative tune. Paul |

Isn't 40 weight was the go to for our engines when they have a turbo?
On a side note, I found this video extremely informative and it is the first time I've ever heard anyone explain oil viscosity in a way that makes sense. |
I now use 50 weight as the top number.
More recently on track it has reached 250*F oil temp since I turned the power up. I need a little bit more cooling or the discipline to lay off the "high boost" button until then. I lack discipline. And it is a very shiny button. For street at your power levels 40 or 50 for the top number would be much better than 30. |

Try cutting open your oil filter to get a better idea of how bad it is. If you see any larger chunks, that's no bueno. Blackstone isn't a bad idea either.
|
Thanks to all who replied to my questions. I'll be going with Amsoil XL 10W40. I've switched off the EBC and running wastegate pressure until I make the change. i notice the Amsoil site mentions 12,000 mile oil change intervals....really? I've been on a 5k regime since I bought the car. Paul |

Check out that video I posted above. The first number means nothing for most of florida and only matters when you go below 32 degrees. At operating temp they are exactly the same (assuming they are both mobile 1 synthetic).
