Not much for updates,other than driving the truck a bit not much has changed and i still have a small list of things i want to get done.

 

The other day my boy made me a hood ornament, he might make another that's a little larger but it looks pretty good on the MJ.

Finally got around to prepping the new header for the MJ, i got the additional O2 sensor bung welded in for the wide band and got the header wrap on.

 

Now to get it installed on the truck.

looks awesome. I wanted to heat wrap my exhaust but wasnt sure about it trapping water and rusting the pipes

My 1st header lasted over 10 years with wrap on it, it ended up cracking one of the tubes but there's not really any rust on it.

Heat is actually a bigger issue than moisture, since the wrap holds the heat in the pipe you end up over heating the header pipes which ends up hardening the metal making it more brittle, you typically get cracks rather than rust.

 

It does however help keep the heat out of the engine bay, you will also get a minor performance increase from the higher exhaust velocity due to the hotter exhaust gasses.

 

Like many things, it's a trade off.

I read all the pros and cons about wrapping headers when I got my Mike Leach header back in 03 and contemplated wrapping or not. I went not and fifteen years later still no problems. It looks a bit crusty but I can live with that. I don't have a supercharger either; maybe I would have wrapped if I did.

The supercharger and intercooler sitting on top of the intake is the biggest reason that i did it to the new one.

 

On other vehicles i typically don't worry about wrapping them.

Today i finally swapped out the old leaky header, the truck sounds much better and my wideband looks to be happier too.

I also tossed on the new supercharger pulley, i only drove it out in front of the house but it feels like it pulls a lot harder.

I was looking at old pics and found one of the contents of my bed, It's amazing that the 4banger can burn out at all with all that weight back there.

 

There's also a bunch of recovery gear behind the seats, it's got me wondering how much the truck weighs.

Since i put the supercharger on I've fought with belt squeals, especially when things get wet.

 

Over time I've changed things around and got it down to just the alternator slipping, today i added some more idlers to get better contact on the alternator, seems to have worked.

The belt is silent now, i even soaked it with the garden hose and didn't get a peep out of it.

I had been using an AW4 trans cooler for a power steering cooler but it gave up on me at Naches last year, since then it has been jumped out.

 

I picked up a new cooler months ago but finally got around to installing it, it's pretty crowded behind the grill so I'm going to try under the hood.

 

I made a mount, just need to get some hose and tie it into the system.

Not very good pictures but i got the cooler all hooked up today after work, I think it should work pretty good.
