Driving to work today, everything going great. I start to notice the
smell of burning oil, assumed it was the car in front of me. I drive
about another 30 seconds and the oil light starts to flicker on and off.
I put the two together and immediately pulled over and shut off the car.
I noticed a small amount of smoke coming from under the hood, I also saw
oil all over the right side of the car, completely covering the back
passenger tire and all over the trunk (swirling air must have blown it
up there). A look into and under the engine shows oil coming from
somewhere around the bottom of the engine. Even though the oil filter
had no oil dripping from it, I pulled it off to make sure it was not the
problem and made sure the seal was still intact. Everything was fine
and I put it back on.
I was low enough on oil only a few ounces of oil trapped in the filter
spilled when I took the filter off.
When my help with supplies arrived, I put some oil in and started the
car. I could see a steady stream of oil coming from the front
crankshaft seal. The engine sounded fine and I HOPE there is no other
internal damage. I would not have done this troubleshooting but I do
not trust any dealerships. I want to make sure I would not be hit with
a bad oil filter or a leaking oil plug your screwed excuse. If the
problem was a filter or something simple, I could fix it right there
with no problem.
A call to Hyundai road side service got me a free tow to the newest dealer.
The results? Huge oil leak from the front crankshaft seal caused by a
"moving" crankshaft. I was told that the crankshaft and bearings will
need replaced along with the seal. Pretty amazing diagnostics for just
about 5 minutes on the lift. At least the repairs are under warranty.
The car has never dropped or leaked an ounce of oil prior to today. I
was less then 3 miles from my house when this happened and there are no
signs of any leak prior to that in my driveway. This was immediate
failure. Scary. I am not completely on board with the crankshaft
diagnosis but since it is under warranty and I have never seen a seal
fail that fast, I am not going to have a second opinion done on it.
Since I am at 60K miles, I have a question about the timing belt. I was
told that to replace the timing belt during the complete engine
disassembly to change the crankshaft, would only be about 1 hour extra
charge + parts to replace the timing belt at the same time. I'm no
expert on I4 engines but how can you remove the head without taking the
belt off anyway? In all fairness, they did say they would call me back
with the exact figures later.
 Funny side note on the oil filter. I took this groups general
advice and stopped using Fram and Super Tech oil filters, the filter on
my car now is the first Purolator I've bought in years. Luckily that
was not the problem. Statistical analysis aside, I would never have
bought another one!
