Broken rings?

Geeze you have complicated life. You really deserve a break and a vacation from all this. You are quite a stud for all you have been through. Your level of patience and tolerance is amazing.

 

All they did was an oil change ? Did they use correct oil or at least same viscosity as when it didn't smoke ?

It is not unusual for an engine to burn oil for a short while when changing from one brand/quality of oil to another. It all settles when the new product has established a new oil film in the sylinders.

The title of this thread reminds me of a "movie" I watched recently

 

NO WAY an oil change caused a ring to fail. What is possible is the oil is incorrect, too thin and or the old oil was too thick or loaded with additives to mask this problem.

Jet change? Running rich? Too rich can wash down the cylinders causing ring sealing problems.

 

Let's see, they drain the oil, put in no oil or maybe 4 liters for a Fiat, run the motor until hot and then check dip stick ...... start filling again.

Mitch, what did your mechanic find on this, or are you still looking for a mechanic?

 

If you are talking about an older porsche, and you went from Dino oil to synthetic... It could smoke like crazy. Been there, done that.

I had a 76 911s that never smoked. Put in synthetic, and it leaked and smoked.

Have a 930 which didn't leak. Put in synthetic... It now leaks.

What car are we talking about, and what oil?

 

When I bought my '84 400i, it started leaving puddles on floor. I change oil before driving much, put in Redline 10W50 and some of the leaks subsided. All leaks eventually fixed with total gasket and seal change along with empty bank account.

Imho, a lot of talk has been wasted on oil viscosity. I have however never seen oil viscosity do anything significant for oil consumption or (hot) oil pressure in a streetcar. If you have low oil pressure, fix the bearings, pump or the internal leak that's causing it.

On topic, I do however have some experience with oil QUALITY and consumption. I have had a few instances where an oil change to another brand intolerably worsened oil consumption and smoking.
Had an oil change done to a BMW that already used a little oil (valve guide wear). I had Valvoline in there and the shop changed it to Mobil super (as I later found out, Mobil's budget line).
Car smoked a lot after the change, especially when pulling away from a light. And it smelled really bad too.
Changed back to Valvoline myself and all was back to where it was. No visible smoke and very little odor.
I had a similar experience with Stabil oil causing smoking. I stuck to quality brands and oil ranges after that.

 

Back in the late 1970s I drove a conventional Kenworth W900 that had a very bad rear main seal leak. We couldn't afford to fix it so I just kept adding oil every trip. And I mean it leaked ALOT! Often, I would be heading out and the only oil I could find in the shop was hydraulic oil. I ran every known type, viscosity, and weight in that engine for over 200k miles. Never had an internal issue even after it was sold to a friend.

I can only state my experience. I'm not proud of it but when you're trying to stay alive financially you do what you can.

 

I think the only way oil can damage an engine is if you run out of it.

 

Or too much.

 

I wish we were closer Mitch...i'm sorry that we couldn't help.
I prey that your motor isn't damaged...

p.s. those are JE rings Mitch... as discussed, there was never any possibility of it being a broken ring...

 

The "broken ring" thing sounded way outside the realm of possibilities to me as well.
