As a few of you have read i've recently been having some knock issues. I started my troubleshooting off trying to drop my IAT's and engine temps.

I took it to a few places and found out my radiator was cracked, so i bought a new one.
I figure while im at it ill replace and relocate my IC lines with 3/4 heater hose.
While i was finagling the passenger side metal line i snapped off the plastic harness to my engine coolent temp sensor so i had to replace it. :rant:
Everything to this point was going rather smooth. I got everything replace, ran, and ready to start filling the cooling system. After i got about half a gallon of distilled water in the radiator i heard a nice trickling noise :squint: low and behold my torque wrench didnt stop at 22 inch pounds heh. Water was flowing down the block at about a gallon every 5 seconds. Heres some pics of the aftermath.

Luckily a welder friend of mine was in the nieghborhood and decided to stop by. The manifold now looks like this :tup:

On a side note, Im still tracking down my knock and my truck is still in pieces. My AFR under WOT has been hovering at or around 10.5.
My question here is, other then the expensive 30 dollar per injector off truck cleaning, is there another efficiant somewhat afordable way to clean out the injectors while they are off the truck?

Re: Updates.

Nope. Not that I have ever heard. I want so bad to build a test bench for injectors, fuel pumps, regulators, that kind of thing but until then its a shot in the dark. Good thing you got that crack fixed, looked nasty. Your 10's AFR at WOT is a bit low, have you tried leaning it out a little to get it in the 11.5-12 area? Thats what I would do. As a matter of fact, started working on my alky bin a little today and I had the 10 and below AFR's and as soon as I pulled fuel, got it to 11.5, the truck pulled a lot harder and and only got a max of 1* KR. To where as before I was getting a good 4-8*.

Re: Updates.

Yeah im gona have to check my stock FPR and see what its running at pressure wise and go from there.

My DM-100 almost sends me into an epileptic fit when i got WOT.. red white red white red white WARNING WARNING heh.

Im hoping the extra cooling the charged air will be getting will help and i KNOW the new radiator will help alot as well. The coolent in the engine appeared to be from 92 so heh. who knows.

Re: Updates.

Well today marks the start of my rebuild. Headed up to napa now to get some more vac line and all my gaskets. Gona get some top end cleaner and hopefully get rid of some nasty buildup.
Next step is EGR/PCV Delete.

As for the injector service,
Is there an easier, at home- off truck service i can do? With current gas prices and my income sending my shiznite to cali just isnt prudent.
