DOD FAILED. CAM THOUGHTS

[decembersend]

Does anyone know if these hoods have a service position. I looked the other day but didn’t see anything that stood out

Nope... I took mine off for my supercharger install last year... Friggin heavy

Damn that’s a shame. I’ll just work under it.

Yes. You need to take the pieces of the wiper cowl off around the hinges, then you take the bolts out of the springs, then push the hood up, and there’s a slot in the hinge you side the bolts in.

I'm going to have to look again tonight, it would make it a tiny bit easier to work on.

Don't use any traditional scraping tools or razors...

Da hell you say?!

I've been reading on various ways to clean the heads and block and some have suggest using purple power. What are your thoughts on that?

I will def make sure all holes are cleared, it appears that any little spec can mess up the way the heads sit.

I've been watching several videos from a bunch of different youtubers to learn the best way to do this. Everyone so far has talked about how you want to make sure the dowel is in the 3:00 position and put the sprocket on the dowel as well with the dot in 6 position . I'm just hoping I remember hahahaha. A

I used the permatex gasket remover foam and a clean microfiber rag. Worked really well and no surface damage or flying abrasives that way.

That works for head gaskets? I’m going to have to try that. Cleaning heads is miserable.

I would go this rout too. I never liked taking abrasives to head or deck surfaces.

I'm going to try it and I'll let everyone know how it worked for me. Hopefully not to much elbow grease

 

[91RS]

Me, too. I’ve got a set of heads I’ve been avoiding cleaning to put back in storage for a while now.

 

[iamdub]

I've always used these things on the iron blocks:

Not abrasive enough to even alter the factory machining grain. I've always had heads professionally cleaned/refurb'ed cuz I ain't taking anything mechanical to those aluminum surfaces.

I’ll be making a build thread but just wanted to update everyone. Most of the parts are here and I’ve begun.

Godspeed, sir. Also, I zip-tied that wiring harness to the wiper arm to keep it out of my way while I worked. It'll save you a ton of aggravation because that thing always seems to be hanging right in the way of whatever you're trying to do.

Also, it's a good time to replace that troublesome oil sending unit and screen when you replace the valley pan.

Thanks for the tip. I was actually trying to move the harness off to the drivers side but sadly it goes down the frame on the passenger side and I didn’t bother crawling underneath to see where it connected to.

I had to replace the oil sending unit two years ago, but your prob right I should replace it again while it’s apart. I did it without removing the intake the first time and that was a pita because you can’t see a thing.

Also, you can safely delete that plastic baffle on the rear of the intake manifold that makes the sender so hard to get to. It's only there for sound deadening and not having it makes literally no audible difference to my ear, yet makes getting to that sender about one billion times easier.

I don’t see anything obvious with the DOD lifters. Is the spring suppose to spin? They all spin so it seems normal to me.

Nothings broken, pushrods weren’t bent, nothing collapsed.

The only thing I could think of is one was periodically sticking. I believe it was on cylinder 8, the oil in that header smelled burnt.

Also the pics of the lifters you can see the pin the other one you can’t. After I pulled them out of the trays I realized you can spin them. But this ties not my question above.

 

[Foggy]

They can collapse internally or your VLOM may have failed too, causing your symptoms..
Either way, now that you are apart, ditch that crap !!!!
I'm not having any issues at all (as I turned it off when I purchased it used) , but I'm
still going to change cams and ditch all the AFM crap. Plus I'm really OCD !

I’m def getting rid of it, I already have the parts.

I’m right there with you with OCD that’s why I’m at a bit of a loss lol, I just want something to say hey it was me I’m broken lol.

I didn’t know the VLOM could fail but now that you mentioned it, it makes sense.

 

[91RS]

There are a number of ways the AFM lifters fail and sometimes it isn't obvious.
