I am hoping that someone can help me out here and try to solve "a big
mystery" that none of my mechanics can seem to solve.
I have a 1995 Dodge Caravan with 170,000 thousand miles. Its the 3.0L V6
engine. A little over a month ago, the car developed a MAJOR oil leak,
where oil would basically just POUR out of the engine. The car would
lose about 1 quart of oil every 5 minutes the engine was running.
My regular mechanic of 10+ years was "positive" that it was the "rear
main seal" and he doesn't do major engine work anymore, so he
recommended some other guy that I never heard of or went to before.
Anyway, I brought the car there, and the guy looked at it, and he said
that the "crankshaft seal" was totally gone, and that the car needed a
new "timing belt" as well. And sense I can't afford a new car right now,
because I am only working part-time, and need transportation, I told him
to fix it.
Plus, I was HOPING to get at least another year or two out of this car,
because 2 years ago, I spent $2,000 dollars for a rebuilt transmission
when the tranny went out, and last year I spent $800 dollars for a new
fuel pump, and another $800 dollars on all new brakes and rotors! So in
the last 2 years alone, I have sank $3,600 into this car!!!!
It took 2 days, and the cost was $800 bucks!!! So, I bring the car home,
and find out that now, the engine is completely doing something else.
What happens now, is that now the engine is leaking oil when the engine
is COLD. When you 1st start the car and the engine is cold, oil DRIPS
out. As the engine warms up, the leak slows down, and stops after the
engine gets hot.
So I bring it back to the guy, and leave it there for another 2 days,
and he calls me back and tells me that he "CAN'T find anything wrong
with it, and doesn't see it dripping any oil", but yet charges me
another $50 bucks to look at it.
So Monday night I put a piece of cardboard under there. Tuesday morning
I go to start it up, and sure enough drip, drip, drip for about 10
minutes until coming to a stop.
Tuesday night I do the same thing, and put a new piece of cardboard
there, and this morning I start it up, and once again drip, drip, drip,
for about 5-10 minutes until the engine gets warm.
So I call the guy back, and told him that its still dripping when cold,
and he says "That's strange", he never heard of anything like this
before?? So now he wants me to drop it off again for another couple of
days so that he can "look at it again"??
So does anybody know what the heck is going on here, and what the big
"MYSTERY" is??? Why does the engine leak oil when cold, and then stop
leaking oil after it warms up?
Does the "crankshaft seal" need time to expand or something??
Any info. and or suggestions would be GREATLY appreciated!!!!
