Jester Posted August 8, 2012 Report Share Posted August 8, 2012 How about a step by step of your procedure? May be helpful for someone else too. Quote Link to comment
]2eDeYe Posted August 8, 2012 Author Report Share Posted August 8, 2012 Yep, I will take pics of the repair as I go. Still have to get my crank pulley off, loaned my puller out a while ago and can't remember exactly when or to whom so I bought a new one and then realized I have to get metric bolts for it again. :lol: Should be picking those up after work and then getting back to it.

]2eDeYe Posted August 13, 2012 Author Report Share Posted August 13, 2012 Haven't got much done...the river called! I did get some pics of the tools needed for the repair. I wanna thank Frank again for hooking me up. :D Here is the heli-coil kit. It comes with everything but the drill bit. Rest of the supplies. The drill bit fits perfect in the old gear hub, there should be a new one with the complete timing chain kit. There is a shoulder on it that will keep the bit centered in the bore. You can see the blue tape Frank added to the bit to keep from going to far into the bore. I will take some pics of how to measure that after my sunburn cools down :lol: Here is another component of the fuel system that I don't think has been in this thread. It runs to the stock vent return line on the truck and on the KA. Quote Link to comment
Pacific coast Datsun Posted August 14, 2012 Report Share Posted August 14, 2012 A minor setback for you steve...& i second the river visit...we do it here too ! Quote Link to comment
]2eDeYe Posted August 16, 2012 Author Report Share Posted August 16, 2012 My buddy had the same thing happen to his ka. He did the same repair and it failed in a catastrophic manor. That bolt has a lot of force on it. I would at least put in a thread insert instead of a helicoil. Replacing the head is the only real way to fix it. -Josh Thanks for the jinx :lol: Look what I found. a little fawked? Yup.... Whut? Oh noes!!! hmmmm Shoulda been a clue, this is not VW tin goddammit! :rofl: Peek.... This is the next plan...maybe..more thinking is needed before ordering stuff. :) http://www.mcmaster.com/#standard-threaded-inserts/=iv7vm6 Quote Link to comment
Farmer Joe Posted August 16, 2012 Report Share Posted August 16, 2012 looks like its already had this issue before.. is that really a heli-coil in there already? fuck it... put an l20 back in.. :lol: Quote Link to comment

Oh noes!!! http://www.mcmaster....inserts/=iv7vm6 Hate to tell you "I told you so"..... but I kinda did :crying: The key locking inserts are kick ass if you have enough material to open the hole up. Honestly as cheap as heads are I would just swap it and never worry about being stranded on the side of the road. Just my opinion. We know I don't have the best track record for advice :rofl: Quote Link to comment

Yep... Fawk no...this thing hauls ass :D Hate to tell you "I told you so"..... but I kinda did :crying: The key locking inserts are kick ass if you have enough material to open the hole up. Honestly as cheap as heads are I would just swap it and never worry about being stranded on the side of the road. Just my opinion. We know I don't have the best track record for advice :rofl: Yeah, you did :rofl: It amuses me to no end that I found that in there. I'm gonna go ahead and try a locking insert. I'll be looking at a few different styles to see which one has the best thread engagement. The one in the link will work, there is enough material there to tap it. I also plan to 'cature' the bolt so that it's not in single shear, should take a lot of stress off the threads. I just can't see throwing away an otherwise good head. BTW just for reference, this fix lasted at least 20,000 miles. That's what I've put on this thing since the swap, not sure how long it was run that way before I got it. Ya'll can laugh at me if it doesn't work out. :lol: Quote Link to comment
Z chopper Posted August 16, 2012 Report Share Posted August 16, 2012 whats this thinking stuff??? just buy what you 'need'. I think about buying stuff only when I don't have the $$ to buy and it hurts my brain. Quote Link to comment
mezoman Posted August 20, 2012 Report Share Posted August 20, 2012 Fantastic. Where'd you get the rims? Quote Link to comment

I think about buying stuff only when I don't have the $$ to buy and it hurts my brain. Got to feel good about the cut before I make it, ya know. Talked with my stress lead at work about the inserts, he said it would be much stronger than the original aluminum threads and thought my double shear idea might work. The inserts should be here on Wed, if I got the time I will do some drilling. Fantastic. Where'd you get the rims? Thanks, the wheels are from a Nissan Titan. I should be getting my turbines mounted up pretty soon, so the Titans will go back into the shed for a while. :) Quote Link to comment
]2eDeYe Posted August 23, 2012 Author Report Share Posted August 23, 2012 Inserts came in, but I spent the day driving my girl to pick up her new ride. :D Inserts, after putting my hands on them I think they will do the job nicely. Driver for the locking tabs. ....and Angies new Xterra to replace her old one that she donated to her son. Quote Link to comment

Creepy Cruiser Posted August 24, 2012 Report Share Posted August 24, 2012 Yep, I totally agree, that's a great move. Quote Link to comment
]2eDeYe Posted August 28, 2012 Author Report Share Posted August 28, 2012 Tires mounted up on the turbines finally. :lol: Still waiting on the 14.7 mm drill bit and 16mm x 1.5 tap for the timing chain fix. Quote Link to comment

The Taterhead Posted September 7, 2012 Report Share Posted September 7, 2012 Is that a toyota behind the xterra? Tskk tskk. Imo i like the tubines better. It's a little more personal looking Quote Link to comment
]2eDeYe Posted September 7, 2012 Author Report Share Posted September 7, 2012 It is a Toyota, there are a couple in the family. That one is a good time in the woods. :) Turbines might be the final wheels for this truck, but I did pick up a set of chevy steelies. Turns out that drilling hardend steel is about impossible :lol: Another roadblock, there is an oil passage above the threaded hole for the idler gear bolt. Not enough meat to drill it out and install the insert. WTF? Sooo new plan is to fix the helicoil and lock the bolt in place with a set screw throught the timing chain cover. Essentially this will capture the bolt in double shear so that the threads aren't holding the bolt in place, they just locate it. Pic of the oil passage above the hole, it's a bit hard to see in this pic but it's there... Quote Link to comment
]2eDeYe Posted October 10, 2012 Author Report Share Posted October 10, 2012 The threads were still decent for the helicoil, so I got creative with some epoxy.... Picked up some Marine Weld, basically JB Weld for wet conditions. Dabbed a bit on the helioil and threaded it in. Then I put the bolt in and let it cure for 24 hrs. Better shot of that pesky oil passage. Epoxy, after some research into high temp and oil resistant epoxy I decided on this. Post cure I have an idler gear again. :D At this point it was time to address the side loading that bolt is seeing. Here's how that went... pic heavy to tell the tale. Got the chain on...now I have to put an insert in one of the tensioner bolt holes :lol: Quote Link to comment
