Ok, I guess it's time for a Heli-Coil.........

[SpiralOut]

Ok well it turns out i stripped the oil line hole one the head where the banjo bolt goes. . I tried Teflon tape and every sealant you can think of, Of course non of them worked. So i am forced to use a helicoil. I am using http://www.dsmtuners.com/forums/articles-miscellaneous/267280-how-use-helicoil.html
as a reference. It seems pretty straight forward but i dont want to make it worse. Are there any tricks or things i can do to make it easier? Also how long does it usually take?

thanks,

if you have it on a drill press it takes less than five minutes

No drill press here. I am doing it the old fashion way. has anyone done this before .

Keep Teflon tape away from engines.

I like to use a thin layer of RED threadlock on the outside of the coil and allowing to dry. Then place bolt after its dry. This will prevent the coil from backing out with the bolt if you ever have to go back in.

Come On Your a Moderator.... Nobody can just Say things like that WITHOUT GIVING REASONING FOR IT
Yes This is not the right use for it here

But O we'll just delete my post or add it to another....

O BTW thanks for the Input........O lack of....

You ever see those goddamned little strings that Teflon tape gets cut into by the threads it's sealing?

Keep it away from cars.

I did this to my car a few years back and had to use a heli coil to fix it. It is a pretty straight forward operation just make sure you take your time and dont rush it. Drilling the new hole straight is the most important part.

I think the most important part would be making sure you get all of the metal shavings out of the hole before you button everything up. You don't want any shavings in your oil feed line then ultimately in your turbo!!

Before resorting to a heli-coil, have you tried just threading in a tap and using a slightly longer bolt to block it off completely?

I ended up doing thin on a friend's Talon as the head he got "rebuilt" from a shop had the oil feed hole already stripped... He didn't even notice until it was time to bolt on the oil feed for his 17c during the build-up.

Longer story short, I originally planned on having to drill, tap, and heli-coil it, but after I got a chance to look at it, I noticed that there were good threads further down in the passage... I ended up just running a tap through it followed up by compressed air to remove any debris. THen used a slightly longer bolt. -Just be sure that the bolt isn't too long as it will also block off the forward lifter oil feed passage in the process. Follow up with a new copper crush washer and you should be good-to-go, no heli-coil needed.

-Needless to say, after my repair in my friend's Talon, he was forced to use an oil filter feed line for his turbo. -Being a journal bearing 17c, IMO, he should have planned that route in the first place

Defiant ever says anything unless its to be heeded or something of inportance. When he says something you just listen becasue he always has a point to what he says...and sometimes it even makes you laugh horrible.

I would agree with the above with using a tap. You might be able to save yourself the drilling and inserting the coil. But if you use the coil, it will be near as if not as strong as screwing something into the block.

Cover the tap with automotive grease. This will lubricate the tap allowing for a easier and cleaner job, as well as discouraging binding. And it also does an excellent job of catching more than half of the metal chips.

The heli-coil will actually be stronger than the original threads in the aluminum head. The heli-coil is the proper way to fix your problem. The only other thing I would recommend would be TIMESERT Check out their product. It's a better/stronger way to fix your problem also. Even stronger than a heli-coil kit.

Interesting "test" done on HeliCoils in Aluminum
