kastein posted:It sounds like it ran for a while on the verge of hydrolocking, too... and then hydrolocked. No telling if the rods are tweaked or bent at this point, if it was my car I'd definitely check that before even considering rebuilding it. It's pointless. Along with the cost of gaskets, bearings, rings etc which will inevitably be done 'while you're there', there's the added labour VS just throwing in a second-hand one. It's a dirt-cheap, dirt-common engine known for it's ruggedness in general. Seems like a no-brainer.

Seems like a no-brainer. oh, I completely agree, I'm just saying... if they're going to consider fixing it, they need to look all the way into it before throwing too much money at it, to keep it from being WAY too much money. Me, I'd head for the local yard, pull one, and buy it for no more than $120, $150-170 with a 30 day warranty, then rip the old one apart, take pictures for this thread, and turn it into a coffee table.

Well yes, I agree with what you're saying, kastein. But I look at it the other way, too. For the cost of a gasket and just 2-4 hours of your time, I'd throw a new gasket and only a new gasket in there (it's pretty easy on most 3800s, I know by experience) AND pick up a new engine. Run the "broken" one as long as you can. :tenbux: says it will still run well as long as it was just an intake manifold issue, even with a hydrolock. Yes, the engines are cheap, but as you said, they're renowned for ruggedness (second only to a few other engines, and the Jeep 4.0, which is no mere mortal and cannot be classified with anything else). I've seen them run with no oil for miles, be filled up again, and then run again for 10-20k without issue and with near full compression. Really, what's the harm in an afternoon's work of a lower head gasket replacement? It's a drop in the bucket compared to an engine pull. Either way, though, take pictures. For the greater good.

SimulatedWoodgrain posted:SII 3800 in that right? What happens with those is the EGR tube that passes through the plastic upper intake gets very hot and over time makes that area brittle. No big deal right? well on either side of it run the TB coolant passages. Brittle plastic+16psi pressure from the coolant system will eventually create a awesome leak inside the upper intake, which will in turn flood the cylinders and hydrolock it. I believe Doorman makes a new upper intake kit that includes a small diameter EGR stove pipe to help prevent the same problem. Previous SII 3800 owner here. Also check the gasket between the throttle body and the intake manifold. In addition to the lower intake manifold gasket leaking on mine, this was also leaking allowing coolant into the the cylinders.

Fun fact, the shop that is in most of his videos is owned by my father in law. Stainless lockwire - good for heat cycles and vibrations. Wouldn't want to swallow one of those at high rpm.

Saw this today on the way home. Would have a better shot but the firemen seemed busy standing around and I was in a hurry. There were two guys in a man basket when it failed, no one died thankfully. I don't see how two men topple a crane unless an outrigger failed.

Mercury Ballistic posted:I don't see how two men topple a crane unless an outrigger failed. Plenty of ways. Poor outrigger placement (soft ground, not using plates), "short jacking" the outriggers (which requires you to override anything I've ever seen to get it out of the cradle), and/or operating out of spec, meaning out at basically a 90 degree angle fully extended......which it pretty much the position that thing looks to be in. You need to understand that some angles and extensions are only rated at a coupe hundred pounds on those things. So two men at that particular angle and extension with a lovely outrigger job in a stiff breeze will absolutely will make that happen. Hell, you can do it just by being jerky with the controls.

Godholio posted:Is it worth watching the whole 20 minute video, or are there just a couple of good parts? It's basically a guy just taking a long time to try & run the lockwire. His biggest problem was he wasn't using math & science when he did it. instead of trying to pull the wire through from the top like that, he should've coiled it around the inside a few times. The angle of the wire wouldn't have been such a problem for him when he was pulling it through the bolts and he could have done it in half the time. Also, before putting them down in there, he shoulda made sure the holes were lined up instead of just going blind.

Of course if it had been me I'd probably be throwing poo poo across the garage.  Otherwise it's pretty boring unless you're into lock wiring things I guess.

You could mark the heads so at least you know where the holes are... But yes, there's no way to "line up" the bolts, unless you keep trying different bolts until one lines up perfectly. And yes, I blew a large part of my past two nights watching his videos. The Orenda Iroquois looks awesome, and I applaud his efforts to restore it.

That's why Sharpies were made They never completely line up correctly, the hole for the lock wire is always drilled in the same spot, but the threads on the bolt are often in different positions, so that they bottom out with the lockwire hole facing different ways.

I've seen lockwire bolts with two sets of holes perpendicular to each other, so the worst you could be off axis was 90 degrees.

Since we're on the subject of cable breaking. The only fatality from this 86 car pileup in Cincinnati was a 12 year old girl standing on the median who was struck by a median cable from another accident down the highway. I didn't even think those cables were under that much pressure. http://news.cincinnati.com/article/20130122/NEWS01/301220042/Girl-killed-275-pileup-mourned

A customer brings in his 2002 Tahoe for a front end check and asks if I can find an oil leak, and to look into why his 4-wheel drive stopped working. In addition to typical wear in the steering linkage, I see this:   Not pictured was the steady drip trail it left on the shop floor on the way in and out.
