Mine has dropped a seat in Piston #4 at 130k!!
My father's dropped at 62k, which is ridiculous.

For those still driving, don't rape your car and watch that heat. Make sure your cooling system is working as it should.

Also, only the intake seats should be replaced on these engines or the exhaust seats drop too ?
