    TTY learned the hard way

    My rebuilt b16 is almost complete. I have taken the utmost care and time to carefully do everything but last night I had a major setback.

    After recieving my oil dowel and o-ring I went to install it underneath the center camshaft retainer. All went well and after checking the torque specs in my haynes (and checking them twice) I commenced to tighten the bolts to 20ft/lbs.

    Thats when the shit hit the fan. I should have stopped after the first bolt wouldn't tighten but my dumbass went on to the next bolt...which snapped.....$h!t. ....and while trying to remove the first bolt it snapped too.

    Upon further inspection I realized they were (had to be) Torque-To-Yield....Months of work were on the line....At 1am this morning I had finally got them both out...I had to use a chisel to cut a line in the top of what was left of the bolts (which were recessed in the holes) while not scratching the surfaces or getting metal chips in the head.....

    So let everyone else learn from my mistake ...DO NOT RE-USE TTY BOLTS..... (ie..head bolts and camshaft retainer bolts)

    Good lesson to learn. Sorry it happened to you man... working on your own stuff sometimes results in these kinds of things. At least now you know you'll never have that problem again.

    He said it already. Torque To Yield. Once the bolt has been torqued to spec, it cannot be reused.

    However: I re-used mine when I built my D15B7. Haven't had the first problem with leaks or anything. I torqued them 1'lb higher than spec. Don't try this at home, I'm just a cheapa$$ ba$tard. Make sure you oil the hell out of them before torqueing or you could snap them without even reaching the torque spec.

    OEM bolts stretch. Most ARP's can be re-used because they don't.

    ARP do stretch a bit as they explain in the enclosed instructions. They tell you what to torque them at based on their length... at least the ARP head studs I have.

    But ARP's don't stretch like OEM bolts do that stretch and stay stretched. ARP's are flexible enough to return to their original shape when you take the load off of them. That's what I meant by "they don't stretch". Any bolt or stud will f#$^ up if it's over-torqued, though.

    Not until you blow your headgasket and have to tell your buddies who are car nuts that you used torque-to-yeild bolts twice. That's enough shame in itself. Do the right thing and replace them with quality parts. You newly built motor deserves at LEAST that much respect.

    Respect? Come on, it's a D15B7... I don't get respect from my buddies for building a 1.5L civic motor to begin with, so I'm not sure any could be lost.

    If you're going to be a cheap bastard... just be prepared to face the consequences, and then you can be a cheap bastard with confidence.

    Hey don't worry my b16 is almost completely new but I didn't realize that those bolts were tty.

    I can also understand what Jafro was saying... With my dual point injection POS I really didn't care and was ready to face the consequences from reusing the head dolts....

    But sometimes you know the consequences and just don't care...but my b16 is not one of them...I care...alot...

    I'll post some pisc tonight of the engine so far and of the snapped bolts.

    No, just a first gen manifold cause mine was stolen by my brother about a year ago....came out of an eg6....but don't think the motor has been sitting around for a year together..the cylinders were bored about a month ago.

    This one was laying around in my random parts bin....50 buck is good....free is better ...and with a homemade block off plate and a couple of vacuum caps I can have the same effect....until I go for some major internal mods and can get a real intake manifold...

    This is with the TB on....all fits nicely...although it's not the prettiest thing in the world

    pretty, no...effective yes


    what all did you do to the motor? did you build it at all or was it just a basic rebuild?

    Basic rebuild.... All new bearings, seals, bored .5mm, cleaned..It's pretty much a very basc but very thourough rebuild...
    I basically want an engine that is factory reliable ....but I have plans on getting a dart b20 block for my long term big boy project.

    There's a machine shop here that did the bore/hone for 120....he did a good job too. they do a bunch of circle track car motors...so I kinda felt outta place but they were really cool...

    Edge Brothers Machine Shop in Jacksonville NC ( PLUG!!!)
    .....
    And I am so convinced on the dart block and the price is a little unsetteling but from what I hear, it seems to be worth it.
