Finally some DM progress
Joseph Cummings replied to mowerman's topic in Antique and Classic Mack Trucks General Discussion
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 -
A New Chapter In the Life of the Duck

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

It's a 2 valve 672 cubic inch block and heads. I haven't seen many of them get water into the cylinder. Sleeve is dry, and the heads don't crack into the water jacket much. I've seen some leak from the head gaskets, but that was external seepage -

Usually white smoke is late timing. Could be a bunch of other things too. Cold, low compression, bad nozzle spray pattern, fuel contaminated with a bunch of gas will all make white smoke too -

Schnabel load. Looks like the dolly might be steerable. -

But he had to, because of the trucker shortage
