Short version: have been dealing with prepping house for sale, listing, tours, open-houses, offers, etc and haven’t had a spare moment in the last few weeks.

A couple of weeks ago I had to get the car out of the yard so that the photographer could get pretty shots for the listing and I was just too tired to push it. I decided that driving it 100’ into the lift bay would either be fine or not, fuck it, and I started it to the pleasant surprise of a quiet idle and no knocking. Drove it into the garage and as it got warmer it started making the noise again so I shut it off, let it cool, and tried it again. Same result; it was fine until it got warm and then that awful sound was back. I stuck my head under the hood while it was idling and the sound didn’t seem to be originating from the bottom end, mostly everywhere in fact, and suddenly thought “header leak”.

Today I finally got to take a look. I found evidence of a leak at the #4 exhaust port and the nuts were barely more than finger-tight

So then I fixed and cleaned up the fan wiring, flipped the rad top mount around and fixed the mounting holes, and installed the fan in the proper pushing position (stupid mis-labeled packaging, grr):



Then went to warm up the car so I could take the oil sample and the battery was dead because I’m an idiot and forgot to plug in the tender when I brought it back into the garage.

Oil sample tomorrow! And probably other stuff since that #4 was definitely leaking and was hopefully the source of the noise.

Matt F........ing Walters!!!!
YAY!!!!
Such great news - SO hoping it's just the #4 exhaust leak - such great news. The Blackstone Oil analysis is still important to begin the baseline of trends....where are ya moving to??

I’ll actually be sending the oil sample to Driven, the manufacturer of the break-in oil my engine guy recommended.

We’re moving home to Vancouver, BC. We’ll miss Seattle (and damn will I ever miss this garage) but we’ll be visiting a lot and I’ll be down here with the car for track events for sure.

Awesome!
Vancouver BC is such an incredible city - wishing you well as you travel back Home. If possible, PM me when you're going to be at a track in the greater Seattle area....I wana see the Bronze Beast in action.

The engine seems healthy. One of the header studs is stripped (ffffuuuuuu) but I re-seated it deeper and will deal with helicoil later. Got the oil and water up to temp and gave it some throttle stabs and it’s fine, the sound now seems to come and go as I listen for it but I put a stethoscope everywhere I could think of while it was lumpily idling at 900ish RPM and heard nothing internal that sounds like clattering other than a couple of valve shims that clearly need adjusting. I seem to have mostly fixed the “exhaust banging on hard parts” issue and the fan now works properly and keeps the water temp at a balmy 84 degrees C on an extended idle, so those are wins. Going to take the oil sample and switch over to moto projects for a bit since the car is clearly fine to drive on / off a trailer. Still don’t know for sure what that noise is but I am at least fairly confident now that it isn’t a rod.

If this engine eats itself in a way that is compatible with rebuilding to a ~3.4 (or I just get a hankerin' for more torque), that and a dry sump conversion is definitely something I'm thinking about for the next iteration. I think I could do a dry-sump LS swap for fewer dollars though, and despite knowing in my heart that I'd be sad about messing with some of the wonderful character that the car has, losing weight from the nose of the car and getting the entire engine behind the front axles is a pretty compelling argument, along with the lot of extra grunt. I'm already running an ECU that would happily manage an LS with four extra wires in the loom, too...

More good news: just got off the phone with the machine shop, and after examining the oil filter that was in the car during the dyno session, they're pretty confident that the type / concentration of particulates in the oil is normal for this stage of break-in. Seems like I overreacted, but I'm going to chalk that up to an abundance of caution about the $yikes and hundreds of hours under the hood of this car.

edit: Also overnighted an oil sample to Driven's analysis lab this morning, looking forward to seeing what they have to say about it.

Matt,

Great to hear that it is not a rod! I was worried for you after all that work that you put into it. Best of luck with your continued build and with your upcoming move!

Thanks!

Because I'm really good at being frugal and I have to remove the headers to install a helicoil in the head, I decided to avoid ongoing fights with exhaust header leaks by pulling the trigger on a set of SuperSprint stepped headers and stepped section 1 pipes.

Which means, I suppose, that I have a set of SuperSprint section 1 pipes with about 4 hours on them for sale. Labels aren't even fully burned off yet. $400?

edit: the Manzo headers will not be for sale, they're garbage but will look nice on the wall of my new garage.

Hey Matt,

I've been following your build, checked out a couple of your videos, and hoping we run into each other at The Ridge so I could see this amazing beast in person.

I live in Vancouver, and know the city well. Feel free to shoot me a PM and I cna help get you oriented in the city. Perhaps we can convoy down to The Ridge some day.

Good luck with the build - looking amazing!

Cheers,
Eamonn aka eggman

Thanks! I will definitely be into a convoy to the Ridge when that time comes

I lived in Vancouver for some time before we moved to Seattle, and my wife was born there so we're pretty familiar with the city. I'm definitely happy to know more people at home, though, so let's make a point of and / or food and / or wrenching after I'm back
