    Default Help please..helicoil pulled out of block for head stud....

    I now have a large hole since the last repair was drilled to accept a helicoil. Is there another product that I can use to get threads back into my block. Please help....I don't want to tear the motor down again. This is a head stud thread that goes into a water jacket.

    Thanks for the help.

    Going to try one of these. It looks like Torrance is the closest place for me to get them. If anyone knows a place closer to Ontario ca I would appreciate it.

    Thanks for the help!!

    find a Grainger in your area. You need one with a 7/16-14 thread internal and 5/8-11 external.

    That's cool as shit!...I probably have 20 heli-coils in mine...including the stud with the nut on the end in the water jacket
    My block was messed up when i got it. Someone had used studs that taper down in the center...they were a little long so they just installed them deeper...far enough so the threads were all in the water jacket and just torqued them down. Had a hell of a time getting the studs out until i figured out what they did...ended up cutting the studs and screwing them into the water jacket and fishing them out


    Correct me if i am wrong but won't 1/2" studs work on BBC?

    I have a Bowtie block I bought from Obnoxious that has 1/2 studs. But you have to drill the heads for the 1/2 studs. Not exactly the right fix for a single bad hole.

    Those look cool,, how do they lock in place? No special tools makes them a ton cheaper, especially for just one hole!

    Looks like grainger requires special order.

    I just put them in with a big azz screw driver.

    Barry, I normally use either red locktight, maybe a dab of J-B weld if its in a water jacket. Hever had one back out before. The thing about these over Timeserts is that they use standard taps and they come is larger outside diameters to repair previously repaired holes like Attack has.

    McMaster Carr has them with a nylon insert to lock them, as well as a dab of some heat activated locking compound on the threads. Never used either specially if it goes into a water jacket. Much rather use some sealer or epoxy.

    Default Keen sert

    The keen serts work well, I think you drill the hole with a 9/16" bit and like GN said you use a 5/8"-11 tap so you dont need a bunch of special stuff. I would JB weld them in so that the threads on the block don't rust any more. I had a 396 block and it had several helicoils and keen serts in it. I finally jb welded in a set of studs and never had another one pull out. I just hate that feeling when torqueing the head bolts and it seems like it is going a little too far before clicking.

    Good Luck,

    Chris
