Gold Flakes in Oil and Age of Motor?

Like I said earlier, I'm probably going to drive it for another one or two k miles and check it again.

If you pull it now before the rods & then Crankshaft are junk it will be some what economical to rebuild. Or you can go the route of replacing the engine every few years & never having one that's 100%.

Roughly how much would a standard rebuild be? Just stock parts, nothing built up?

Thank you. Is that yours? Looks like a very clean bill of health!

You will need at least 2 good rods & most likely a whole set of rod bearings & ARP rod bolts. A gasket set is about $300, ARP rod bolts $160, bearings $125., Rods ?? You are looking around $1,000 minimum since you want to do whatever you can while you are in there. Plus labor!!

Rings?
Are these cylinders nikasil'd, Or should they be honed?

Maytag, I believe the cylinders are coated with Lokasil (sadly Not Nikasil) and the concern is that they may be 'oval' not round.

Ideally would be to get the LN Nickies but they would increase the cost of the rebuilt..

If you have no scoring, and decent ring seal, then you can refresh an m96 fairly cheaply. It wont be perfect but should extend the life a good while

Update:
The flakes aren't gold, as I previously stated, but silver. The oil on them made them appear gold

I went back and looked carefully at the drain pan and I took a magnet with me. The flakes are indeed ferrous.

So, could it still be rod bearings? Or maybe is the the IMS bearing ready to go? It has the single-row bearing.

At this point, oil analysis is still probably your best course of action. I'd also recommend a filter magnet or magnetic drain plug in the mean time to snatch up any ferrous material that gets loose in the oil. Pull the filter and take a peek as inspired between oil changes. Filters are cheap and swapping out a filter just takes a few minutes and barely any oil.

Note my signature, but I would not be seriously worried about the engine yet. Most people never even get a look at the oil in their cars and most oil changes will have some degree of trace particles.

After it was first posted, I did that to all my 986s and it has worked well.

Thank you! I'll definitely try the magnets. I'll do an oil analysis on my next oil change.

Thank you all for your input!
