Default Re: Cylinder bolt problems about to throw it away

Not sure how much helicoils cost because I use Timeserts instead. However, I do know that Harbor Freight carries helicoil clones and I'm sure they are cheaper.

Do not reuse the OEM studs-they suuck. Get all thread from fastenal (what I usually use) or buy replacements from

Please review my tips for newbies. One tip is repalcement and JB welding of the studs so they never loosen causing mistaken tightening up of acorn/headbolt nuts which strips out the partially backed out threads on the block. All of my tips are based of years of uncovering issues with HT engiens and are written to help make your engine bulletproof.
