That's a tricky one jlb.  Mechanic has no receipts from his parts distributor for the head gasket.  Its from a pretty reputable, local shop but they don'tr see where they bought it nor where I paid for it.

 

We know they sent the Hamilton Cam required clearances to the machine shop for the correct depth so that's where the assumption of stock thickness is coming from.

 

The work was done back in April. So memory isn't serving well.

 

Here's a video of what a cold start without a block heater looks like, when you can get the truck to idle.  This was back in the spring right after the new VP44 was installed.  About 30 degrees outside, after being out all night.  These days it won't lope along like that without the starter continually engaged.

Its not cold enough for a serious test yet but I may have found the cold start issue.  I replaced the grid heater relay and one of the two solenoids looked like it had exploded inside the housing.  after I removed it I tested it with a battery and an ohm meter and one relay worked but though the sploded one did clunk it didn't actually make any contact.  So I guess one grid was heating but one was not.

 

It was about 38 here this morning so not really cold but it started right up and I think it wouldn't have without replacing the relay.

 

By the way, relay bought through auto parts store (which takes three days to arrive) - $75.  Relay bought through PartsGeek.com which takes three days to arrive - $45 including shipping.

I think a lot of people DID suggest checking them but I was too busy looking for complicated answers.

 

I did notice that there are separate relays and separate control wires to those relays for each grid heater.

 

Could I guess that both fire for a cold start and one fires continuously based on the Incoming Air Temperature sensor to keep warming the air until the manifold warms up?   That's the reason for two solenoids and two sets of control wires?

Been noted for History hahahah

 

Noted for what? Had a dead relay. Swapped it out with my extra and it's happy as a clam.

There are two grids in the heater. They split the amp draw between the two as to not kill a single relay. Both come on and are pulsed until the ecm (pcm on a 12v) says to stop.

The only way I would EVER recommend a 4k box is if the truck only saw the street from the deck of a trailer on the way to an event. ...even then I would hard pressed to recommend it. 

 

Get the normal Quad box with the Iquad.   Then load the V2 tuning on it and be happy.

Ok.  Quad (non 4k) with the iQuad is on order and will be here by the weekend!  

 

Now I have to figure how to yank the Edge and put in the iQaud.  At least it will be a warm weekend!

 

Thanks for the help fellas!  Next time I'll listen to you first before over complicating things. :)

Quad install should take you no more than an hour taking your time and routing wires properly! You've always got this site for help if you need it too. 

If you decide at some point you want to try the 4K box let me know and I'll let you borrow mine. The harnesses are the same for both boxes so you can plug it in and select the right vehicle on your phone.  

It'll reassure you made the right decision with the standard box.

TFaoro I tried sending a PM but the site won't let me.  

 

Did you notice any difference with upgrading the intercooler?

 

I've been through 5 Mishi radiators so I would go Spearco but that's a spendy chunk of aluminum!

You would never notice a difference.  The stock intercooler is very capible of handling your fueling.

I think Mike is working on that now. 

 

I've noticed my engine runs a touch warmer because the intercooler blocks some of the airflow.

 

As far as air temps, I've noticed nothing on the IAT gauge. I think that's because it's at the back of the engine but who knows. I ONLY replaced my stock one because it was leaking out of 3 or 4 tubes where they enter the end tank. 

 

I've yet to hear anything like you're experiencing with their radiator.... What keeps happening? I've been considering getting one so that's not good news to me.
