Why dint it run last year?


Still turned off at 55 or above and I eventually gave up on it. But now I'm back,...and everything's going pretty much the same lol.

I figured I should get this thing into driving condition. Everything left to go seems to be so nickel and dime, and my work thus far has been that, too. Plenty of little covers or loose hoses or bolts laying everywhere. Not to mention a number of cig butts, leaves and material scraps all inside the thing. I decided to hop in back and make my way forward.

Getting the last bits of fuel stuff was cake, and other than removing a mess of tools and loose connectors, there was nothing to the rest of the interior. Take out the parts and shop vac the rest. Just that little bit perked me up; it's starting to look "ready". Things started coming to me here and there, some random task I put off for later and forgot over the 14 months it's been. Add weight, finish off soldering, get clamps on that hose, all the little niggles. With no ability to clearly recollect, I decided to do the fuel leak and think as I went.

That job went fine. It looked to be a case of me simply choosing the wrong size washer to use when grabbing from my Sack of Many Things, so using these ones worked straight away. Turn the key, pump primes, and no leaks. I guess... oh! Let's start and run, get it up to temp. And I know the rad's dry, so let's start there. I begin to fill it while looking around trying to remember when I notice water is pouring from the underside.

I couldn't (and still can't) see where it's coming from. I've crawled under, taken off tires, I just can't see it. And in trying to find it, I stuffed my arm in to feel for it and wound up ripping apart some wiring I hadn't yet soldered. Round and round we go.

Near as I can tell it's the crossover pipe in back, the one I commented on during the rebuild that I didn't understand how it doesn't leak. Plus, after all this thinking about it, this thing has ran, on the track, no less, and wasn't leaking then. It's certainly not a case of not noticing, as while I remember many comments about leaks, this one is such that I wouldn't just run out before the race ended, but I'd run out before I even took the green. It pours. I'd have noticed. And the s#$%iest thing of all is that I see no way I can even see or touch it without either removing the entire intake manifold and all attached cooling accessories, or removing the entire engine.

Ugh.

So... what I think I'm gonna do is fix the wiring I just broke (it doesn't even turn over at the moment =p) which won't take but an hour. Once running, I'm gonna call the shop and see if they got time. Set a budget and see what happens. There's something about turning a wrench I have really missed, something about correcting a failure I still dig. But, there is something about this specific car and situation I cannot f#$%ing stand anymore. Probably it's the 100% failure rate.

We'll see.

Is there enough space for you to stick your GoPro in to see if you can identify the source of the leak?

Duct tape it to a stick if you have to. They also make mechanic tools with extendable mirrors.

Perhaps just enough. If my massive hands fit, a GoPro should. However, that's all well and good for the ID but does not a thing for the repair. One way or the other, something is gonna have to come off or out. Thank Christ for this thread...

I just looked at the pics from the rebuild. There IS a bitty hose that comes off the crossover, and there IS the coolant temp sensor, either of which could be the culprit. And oh how I would love to solve this with little more than a channel lock or 10mm socket. But barring that, there just isn't a single thing going on on that side of the engine. It's flat and void of accessories. It can only be one easy hose, one easy sensor, or one bitch of a crossover pipe. (Stay tuned where we find it's coming from somewhere else entirely and just happened to find it's way where it is now =p)

Oh well. Cryin' ain't gonna fix it. Thanks for the tip =)

ETA: Yup. GD crossover pipe, leaking like a sieve right at the thermostat. Warmer weather meant fewer layers and I managed to get an arm all the way in.

The thermostat is easy. I reckon I'll try to access it through the thermo as opposed to removing the entire intake manifold and all those connections. Watch how I fix this and the other side starts leaking, requiring an intake manifold removal =p

Isn't this radiator a recent acquisition? Is it still under warranty?

Oh god, no. Came with the car. But it ain't the rad. And golly, but does it feel good to actually FIND the culprit.

Finding that it might have just ended your career? Not as pleasurable.



There it is. That pipe on the bottom that shows a compressed rubber gasket between it and the thermostat, that's the crossover. And sure as s#$%, after a parts run store for an elbow ratchet, I got all of the intake off and saw it leak clear as day. I even asked for a gasket kit while at the store, I was that confident. What I did not foresee was the leak not coming from a bunk gasket, but leaking because the entire hole into which the thermo is bolted has snapped off. Pulling the thermo back into its natural seat stopped the leak dead.

I don't know what to do. I can't even imagine a scenario that would have caused this. And I sure as s#$% have nothing in my Bag of Many Things to address it.

I know I can't just thread the bolt through. It almost looks like it would work, but I'm sure it'd just pull the thermo too far the other way and still leak, or it'll just snap the bolt clean off. I'm sure the proper fix is to build the material back up via weld and re-tap the hole, but f#$% me if I or anyone could do that while the motor is still in the car. F#$% me if I could do it under the best circumstances period lol. So it looks like my only option is to half ass weld the balls right off it and hope I can bodge with the best of them.

Ha. Well, f#$% that, too. Just checked. Aluminum block.

I, uh....

Yeah.

How much to swap in a new engine? Is it time to put the unicorn out to pasture?
