I bought a 95 2wd, chevy astro 2 weeks ago.
I checked the car, the oil was clean, and everything is ok. I liked and
bought the car.
The previous owner told me he bought the car 2 months ago, with an
engine problem. He had the crankshaft and some of the push rods
changed. He drove nearly 80 miles after repair, and sold it to me.
I bought and start driving. The engine was strong. But after 50 mile, I
notice the engine misses lightly. I checked the spark plug wires and
notice #1, 3 and 5 wires are burnt in some parts. I changed the wires
and now it is missing hard on #3. At the same time, I start to feel
that the engine is not as strong (This is my 3rd astro/safari van) as
it was the day I bought.
At the same time, I start to get an oil leak. It is coming from oil
filter adaptor. As I start to work on this, I notice the oil is
extremely dirty. It is not old like any oil after 3000 miles or
brownish muddy like if you had a head gasket problem. It is not
transparent and I feel like it has many shaving in it.
If I'm right to worry about shaving, is it normal on new crankshaft
or am I killing the engine.
