Thanks guys, stocking up on band-aids for inner fender removal:ANGRY_~317: This reply from ARP regarding head studs... "Bob, The kit does come with enough lube to install those studs and also that kit does fit both the 6.2L and 6.5L. Regards, Zac Kimball Automotive Racing Products PH: (805)...

I checked on the Felpro and they do list 6.5 and 6.2 as the same. ARP site only list the 6.2 and the duramax. So sealant goes on the stud into head and then ARP special lube goes on top of stud, washer and nut, correct? Thread chaser on the block threads, any other tips/cautions? Bob

Trying to order ARP headbolts and my automotive supplier list 6.2 but not 6.5. Are they the same? (i am thinking yes).

Thanks Aces, still can't believe ARP stud/heads are doable in truck, so close to firewall!

Good to see your back on the road again Andy! I wished you lived closer I would rent your boys for a few days as I just found out today that both the head gasket and water pump are leaking. The truck has been parked a lot lately as it is not our daily driver any more. Had to take it for a...

Make sure all the injector lines have their rubber insulators in place and that the lines are not touching each other or other metal. If they are that will give you noise!

These 6.5's can sound like a rod bearing gone when to far advanced. I would try to get it timed, after putting the Heath computer in it could amplify the problem as it does "learn" as you drive it. There still might be a bit of air in one of the lines causing an injector to not work and would...

I have seen on some brake light switches that they are multi functional (control more than one item) Never had to change on my truck yet, but if it is multi functional I would replace any ways with a GM original. If it is just a simple brake on/brake off type, test like buddy says and pay...

"I believe that the TCC must be locking" I wonder if this is the "hickup" or "fishbit" your feeling?

Definitely get some lube in the fuel, that cleared my 35/36 codes. I would replace the brake light switch as it maybe linked to the "no cruise" issue too. I don't know if that 41 code refers to problems with emergency brake, regular brake system or both! That is a pretty good TDCO if it...

If you have the filter remove it as buddy recommended first, this usually works, mine has been without for years. If you need one Heath has them. http://www.heathdiesel.com/P/HDP1559/

I had a friend years ago making custom headers and he filled the pipes with sand before bending and that help prevent collapsing during the bending process.

Just a supplement to buddy's post, here is the pin designation for OBD1 if you haven't found it. http://www.thetruckstop.us/forum/showthread.php?589-6.5-Diesel-Technical-Library&p=111592#post111592

Check my previous post for the link and what some do is run a fuel pressure gauge which shows pressure under various conditions...great tool!:cool:

Trouble is, is the 6.5 will run without the lift pump (hard on the Injector Pump) but is hard to tell sometimes. Under load it will act up quickly, may exhibit starting problems etc. One way to tell is with a 12v volt test light or volt meter on the power connector going into lift pump while...

OPS go with GM, they do go. Power to the lift pump goes through the OPS, this is a safety device which cuts lift pump if engine stalls in a rollover condition. One of our venders has a extension for the OPS if you do replace it it will make it easier next time. It is on this page with all...

And this from someone who claims to not be very mechanically handy!! Great job! Handy with nice pictures also, you can be a new contributor to the DIY section. Have fun driving it now!

Bill Heath will treat you right, and is the 6.5 Guru and will share that knowledge if you need to give him a call.

I think NVW covered it, I have experienced PMD issues in the past. Stall is instant and progressively gets worse until no starts happen. I had one replacement that lasted two years and replaced under warrantee that would act like that only when cold, from one to multiple stalls but didn't...
