| 1998 Volvo S70 Engine |
This question comes from Shawn in Atlanta. He actually have a 1998 Volvo S70,
and he would like to find out if it is necessary to replace the engine
on his car. He said that his car does have oil/water mixing. He noticed a
milky residue on the oil cap, and a few bubbles. The car will start and
idle just great, but once driven for 30 minutes until 1 hour, the car
will being to shake and stall. Shawn will be going to autozone to rent a
compression tester, woud anyone recommend any other tools or diagnosis?
Answer: If you have
water in your oil or vice versa its one of 2 things; blown head gasket
or cracked block. Either of which does NOT require a compression test.
You would use the test if there were no signs of water in the oil.
Regardless of which it is, your engine is going to have to be taken
apart (atleast the head to look at the gasket). You’re going to have to
take it to a shop. The technician will be able to tell if its the gasket
that has failed once the head is off so be leary if they inform you
they need to investigate further. If its not the gasket, just replace
the motor. It will most likely be $1000 or more, so I would seriously
contemplate just buying a new car and selling this one cheap to someone
who can fix it themselves.
