View Full Version : What thread chasing set(s) to buy?

Before I assemble the motor, I'd like to clean out the threads. It seems that there is very little available for metric thread chasing sets, and what I do find usually doesn't have the M11 that you need for the head bolts. ARP sells the M11 chaser individually, but it's not cheap.

So... what are you guys using? And... what threads really need to be chased? It seems that only the blind holes would be necessary. Can I get away with just the M11 for the head bolts or are there other critical threads that should be chased?

It's not that I don't want to buy the tools, but realistically I'll probably never use metric chasers for anything else again, so if they aren't necessary, I'd rather save the money.

Old head bolt w/ some slots cut across the threads will clean the nasty's out of the threads...
I use a thin cut off wheel and make 2 cuts, 180* apart.

x2, make the thread chasers unless your going to build engines professionally.

that what we used to do at the dealer !

special tools are nice to have but alot of your own homemade tools are just as effective

I bought a kit from Craftsman for $80.

Best money I've spent.
