Odometer would still be wrong and ECM/transmission would not get a corrected signal.
I didn’t know these old Cruisers had electronic countermeasures. Cool. Where’s the button for that?

Odometer oschometer. I only care about the speed being accurate. :p

Many of us don’t know the true mileage anyway, because who knows what sizes the PO has been running for the past however many years?
 
Some of the damage from the my lack of following my own instructions. The downpipe was able to move quite a bit since it didn’t have the supporting clamp in place. It melted one side of the brand new EGR modulator cap. It dumped a lot of heat onto the wastegate (which is already hot) and it started scorching the wrap at the spot where exhaust was leaking. Lesson learned.

Beautiful heat tempering.

What temps are required to singe that wrap?
 
One last post to showcase what happens when you don’t follow instructions. Everything was going back together after the exhaust leak. The new downpipe blanket went and and in doing so noticed the burnt edges of the turbo blanket. Took it off only to realize the exhaust leak had destroyed the blanket. It had to have happened when we were really pushing it and the exhaust could have easily hit 1500°+

All from a stupid clamp not being installed. Lesson learned and luckily I have extras of everything.

Looks like it saved the paint on your hood from cooking off
 
Sorry folks, I left very early last Saturday and traveled to Southern Oregon and then to Etna in Siskiyou County which sits half way between Medford and Redding. I had no wifi nor cell coverage, storms kicked our butts in both directions. I just got back and I'm trying desperately to respond to all the calls, texts, emails and orders so bear with me. For now I wanted to talk about the truck and how it behaved on the 1500 round trip this past week...

The truck was freaking amazing. So absolutely happy with how it performed. I would be totally enamored if I didn't just leave well enough alone and decide to make some adjustments to the downpipe while I was showing my cousin all of the handiwork. He had tons of questions and I thought it would be better to show him. So I did. And I regretted it almost immediately. I was using the SAME Clampco V-band clamp I've been using since day one. Always was fine until, well...it wasn't. The nut galled the thread on the t-bolt and stripped the hell out of it. Now I was in a jam because I didn't have a spare, doh!

We wound up cutting off 1" of the galled thread and then used a die to clean up the rest. Then the standoff side was now too long so we cut off about 3/8" of the clamp's stand-off just so we could actually get the nut on. This forced us to stay the night in Petaluma. In the morning I hit up the local big rig exhaust shop which was IDEAL for helping with turbo issues. These guys know their turbo s***!

I got a lesson in v-bands, flanges, gaskets, turbos, clamping, gaskets, v-band tape, etc etc. Needless to say I learned plenty and I will be adding some of those ideals into future developments. Anyway they had what I needed and within about 15mins we were on the road again North.

Being able to charge past everyone in the fast lane UP EVERY INCLINE is just so much fun. Its not a fair comparison since it has been very cold out all week but engine temps never got about 194Âş and it didn't matter how hard I pushed it.

One of the things I don't really get into discussing is gas mileage. Its going to be different for everyone's particular driving style. I will say though that on flat ground, averaging 60-80mph, I would routinely hit 305 miles with the fuel light on. Fill-ups were generally 20, maybe 21 gallons. That puts me solidly at 15mpg. If I'm really hard on the truck doing long climbs then I would be filling up around 270/280 miles. My SC, on a freaking GREAT day with a tail wind, gets 220 miles a tank.

I am now at 180,550 miles and 2200 of it since adding the turbo.
