Is it cheaper to replace the engine in a 2006 Saturn VUE AWD than replacing head gaskets and flushing the engine? This is the V6 motor.

just completed a plug removal and install on my '02 awd v6. if you have the time and patience it's straight forward; common sense was most helpful. to gain access to the plugs, both fore and aft, you must remove, in short, everything near to, associated with, the air intake system. common tools plus a 1/4 socket, with 8 inch extension to hold a #10 star bit. these star bolts are under the rectangular plastic plate atop the intake. once you have those out, disconnect all the wiring, carefully. lift the intake out, look for plug covers, fore and aft, ignition assembly lays atop each row of three plugs. with the hands of a surgeon, remove the ignition assembly, and by golly ye shall see your reward. easy from then on.
replaced my plugs with the iridium 'honeys'; marked improvement in starting, acceleration, smoothnes, noise, and gas mileage to the value of + 3.0%. changed out the oil with mobile1 extended performance, changed transmission fluid. took a shower. time involved, 7.0 hrs. dealer be damned,,priceless!

just did one today. removed housing from car, and used a press . be careful of aluminum housing. also used penatrating spray. clean oxidation from inside bearing hole,then lubricating, helped in installation

SOURCE: front hub is stuck to knuckle.

spray with penetrating oil and let sit. hit with a big hammer. if it still will not come loose remove knuckle and use a press to remove bearing.

Drop in to autozone, or Pep boys and have it scanned, free, for trouble codes then go from there. Could be something simple & cheap

Under the intake manifold,  it will need to be removed.  Not too hard to do for the average diy but recommend buying a repair manual as a guide.  you will need a 1/4" drive T30 torx socket with a long extension one of the bolts is hidden but the others are under the black cover on the top of the intake.  you will also need to remove the coil pack held on with torx bolts.  8 or 10 inverted torx socket needed for that.
