Good Evening, - 2000 Honda Accord SE, - Engine type F23A1, - Plug type NKG ZFR5F 11 - My daughter & I just finished her head gasket replacement only to end up with a stripped plughole in the head. I know I need to tap the hole but with what size? Do I use a helicoil and the same size plug or a larger size plug? - Do I have to remove the head again to get the shavings out of the cylinder or can I vacuum out the cylinder using a penlight and a mini attachment on the vac? - We also cracked the knock sensor. Will it work if I glue it back together? Will it kill the computer if I start the car without it? A replacement costs, Advance auto parts $112 bucks & Oâ€™rallays $ 135 bucks. I rather not spend another ~$140 dollars on this project. Thanks in advance!
