E6 350 Popping from Exhaust
Joseph Cummings replied to Sy McCarty's topic in Engine and Transmission
Only when you back off the throttle? and as soon as it hits idle, it goes away? Dropped exhaust valve seat. With the truck idling crack the injection line at the pump one at a time. When you crack the one and it goes pop pop pop from the exhaust, that is the cylinder with the dropped seat. When there is zero fuel delivery the seat comes loose and makes that popping noise, as soon as there is even enough fuel even to idle, the seat expands and seals in the head. It's a pretty common problem, especially with heads that have been redone by some third party, They don't fit them tight enough. It happened to me so many times that I only trusted heads I did myself, or the heads Mack rebuilt at their Hagerstown plant -
For a lot of people it's cheaper to buy their insulin at Walmart and pay cash than it is to use their insurance and pay the deductible. Big time predatory profits in pharmaceuticals. In Germany Ozempic is like 60 bucks for a month's supply, in the US it's like 1,500.

Not sure what to say

It might be a little late to help you now, but Walmart sells Insulin for $24.88 a bottle. All three types 70/30. N and S. One is long acting, the other is short acting, and the 70/30 is a combination. No prescription needed. Ask for the ReliOn brand. Everywhere else the same product is like 165 bucks

That surface has to sit down flat onto the rocker shaft mounting. The problem that happens a lot is people loose the correct washer that goes on the bolt that holds the rocker shaft to the head. So then they put a regular flat washer on it. The OD of a standard flat washer is too big and the valve cover bolt hits it on one side. That shoulder outlined in red will be sitting on top of the too big flat washer. There is no need for double fiber washers, or doubled up gaskets, or RTV if you use the correct hardware and press the rocker covers straight in the area of the bolt holes. I used to use an arbor press to press them, but no reason you can't use a hammer and a punch. And yeah on some of the early engines there was a clip so the bolt and fiber washer didn't get lost while doing a valve adjustment. I think they stopped using the clip in the early 60's -

Here is the Mack. I remembered wrong. It's a 1949 LF https://rmsothebys.com/auctions/hf12/lots/r107-1949-mack-series-l-single-axle-truck/#smallgallery_1140854 -

I remember when they used to make chocolate milk out of the "onion milk" to hide the onion taste. Happened when the cows ate the wild scallions -

Made in Milton Pa because of the Tomato's. Our neighbor Ray Bowersox used to have a contract to haul for them. He was Milton Transportation and I kinda remembering him owning an IH dealership. His antique collection was huge, and really nice stuff like this too. He had a 707 gas powered LJ that looked brand new. I think it was a national first place winner https://rmsothebys.com/auctions/hf12/lots/r101-1931-duesenberg-model-j-barrelside-dualwindshield-phaeton-by-lebaron/ -

If those bolt holes are dimpled in, you want to take a big flat punch and drive them out a little. Also make sure the shouldered bolts screw all the way into the rocker shaft mounts and the shoulder sits tight on the mount. Lots of times incorrect washers get used on the bolts holding the rocker shafts to the cylinder head and the rocker cover bolt bottoms out on the incorrect washer. -

I thought you were Polish Yeah amazing how fast I went from thinking I was going to get my baton twirled by a hot Irish chick to cleaning up purple SpaghettiOs. Worst part was I promised I'd have her home by 11 -

I can't stand the sight of them. I was at a party one time long long ago and this red headed baton twirler chick puked SpaghettiOs all over me after drinking too much blackberry brandy. -

Can't hurt to try. Lots of times times it'll look wet around that cylinder's exhaust port. Taking the exhaust manifold off is usually a dead giveaway. Usually number 4 or 5 lets go first. Cracking injection lines one at a time and listening/looking for a change in smoke and blowby can be helpful too
