Things that wake me in the middle of the night

I'd think if it was one of those clips she would have blown sky high by now though..lol.

From reading posts about those buttons, I think it must be quite an obnoxious clatter.

I ran into a FB post where a person had a push rod fall into the engine because of this. One commenter posted this YouTube video for installing bolts. If I’m not mistaken it was ether @Will L. @WarWagon or @ak diesel driver who had mentioned something about doing this same thing.

Here’s the FB link to that post. I finally figured out how to copy those post links. Lol

That same mod is on here somewhere

Here it is. I reread and added a post to it.

Replacing Rocker Buttons

My rocker buttons were all holding up just fine, but with nearly 300K miles on this engine, I just couldn’t bring myself to put the rocker shafts back on with the nylon buttons still in place. I did some searching to see what other options were out there. Just replacing the buttons with bolts...

I’m replacing with the plastic rocker buttons which are well known for going over 300K miles. Truck is at 232K miles, so these will outlast the engine.

I may go back and look into this for a winter project. that is if I don't run across a cheap engine to work on fixing up for my truck. I like the bolt idea with the saddle washers

I don't like the flat nuts inside the rocker arms. Also do not like the additional side-to-side play in the rockers. You're adding potential problems in exchange for the believed security of the nut and bolt system. The plastic retainers have proven themselves for over 300K miles. Just change them out when you're in there.

 

[Will L.]

With 200,000 miles on an engine- absolutely just new plastic.
But many have seen them fail in the 150,000 mile range. I have seen enough that it is why I hate the fuel lines over the covers. So a new engine, I can see the change if the engine is expected to not get opened up for 300,000+.

I agree the way it’s in the video is insufficient to be a solid upgrade over the plastic. The more I think about it- solid round bar inside the rocker shaft that is tapped for all 4 bolts is the way to do this mod. And bronze saddle washers that have same OD as plastic keepers.

In your situation- definitely just new plastic. Maybe if you freshen up the other engine it would be worth it.

Injector lines and valve cover off in 30 minutes using this:


And for peace of mind, all 8 buttons were there:




New retainer buttons going in.

custom line wrench- nice.
Sucks to have popped it apart and didn’t need them now.
But proves previous owner has replaced at least one before you got it. How many miles were on it when you got it

 

[MrMarty51]

The PO most likely placed that button down in there just to mess with a latter owner.
Buggers.

150k when I bought it back in January 2010.

My crows feet are down in Fullerton and Harbor Freight is out of stock. Had a cheapo set of made in India box wrenches I can’t remember where they came from, so out comes the grinder with the cutting wheel. This works much better than the crows feet.

It will be back together tomorrow.

 

[Will L.]

So do you see that it lost a rocker arm button before the 150k mark if the previous owner lost that in there?
sometimes they last a long time, other times not so much. Flip of a coin

I have no idea. Could have been me when I did the other side. I often put stuff on the as a temporary holding place while working an it’s easy to knock the stuff off.

 

[MrMarty51]

I once found a 1/4” drive Snap On socket, swivel and short extension, down in the radiator support of a 93 GMC THAT I on e owned. It had been missing for several years. So now I have a spare set of those items.

Got it back together and running. White smoke on cold start up is gone, but I’ve got a leak on an injector line at the IP. Fuel is leaking at the transmission bell housing pretty good. Should have ran it without the manifold.

[Big T]

Update on this. Found the fuel leak. Completely whiffed on tightening the bottom line. Corrected and tested by running with the manifold off. Will put the manifold back on tomorrow between meetings. Just ran out of light and need to be able to see that everything is clear from under the manifold before tightening it down.

 

[Big T]

Oh and running it without the manifold reminded me how important the grounds are. Don’t ask.
