Hello,

The work on our Chevy truck is going well but I have a (maybe stupid) question : How is the head of the engine beeing oiled ? It seems to be no connection with the bottom of the engine, and the cover of the head is not made to be "oil-proof" ?

Thanks for your help !

Not a stupid question at all. The head upper rocker arm/tappet area is oiled by the use of a "felt material" pad. This pad measures approximtely 8mm thick, 90mm wide, and 410mm long and lays on top of the rocker arms. You saturate the pad with oil and squeeze out the excess when installing.

The rocker cover upper surface has two pair of holes, one set near the front and the second near the rear. If you look at the bottom side of the rocker cover you'll see two parallel channel type sections with a series of holes along their length. Periodically you add oil to the felt pad by squirting it into the four holes and in theory it travels along the channel and weeps into the felt pad.

Gege;
This has been covered many times before. Remove the cover . There should be a felt pad in the top of the cover. Oil it and put some oil in the recessed areas around the valves.Put the cover back on and then you can add oil in the 4 holes in the top of the valve cover every few hundred miles or as needed. Do a search on this site and you will find many threads on this subject. If your pad is missing; go here to order a new one. Good Luck.

Don't forget the "O" felt rings on top of the pushrods. They must be oiled also.

Antique Mechanic is correct. Both SSG26K and I failed to mention the "O" ring felt pieces that are part of the oiling package required. Each rocker arm adjusting stud is supposed to have a felt "O" ring positioned over the ball end of each adjuster and they need to be oiled periodically also.

Hi,

I found in the past that oiling the felt pad on the top of my 28 usually meant oil went everywhere. I now follow a practise of a few others, being at least once a week or before a long trip, I lift up the felt pad and oil directly the top of the valves, the oil hole in the middle of the rocker arms and the felt o rings on each rocker arm adjusting screw. At the same you can visually check the amount of oil in the head pockets and top up if required.

The above works for me, but no doubt there are others procedures the people follow as well.

Regards

On my 28 I do exactly the same as you do. One extra I did, and am sure it's the way it's supposed to be, was tuck the RH edge of the tappet cover inside the side plates. This way most of the oil runs down to the cam followers. Of course can only be done on a 28 model.

MANY Thanks to you all for your help ! I will forward this information to the mechanic, he will be very happy about it.

Here is a picture of our truck today. It looks finished, but there is all the electricity to be done and some details inside.
I decided to leave the headlight which were on the truck. They are a bit to young, but have been repainted and re-nickeled, I think it allright, isn't it ?

Very nice looking truck.

You could sell the headlights on the truck and have enough money to purchase the correct lights. Might even have some left over. Would make the truck look better.

PM. sent

Very nice looking truck. I love the colour. Are you planning to give the wheels a make over as well?

The wheel have been re-vernished (black and transparent) but have a lot of dust... but that's a good point.
- They are not turning "round", what can we do for this, except changing them?
- How was the finish on most truck originally ? all black? black/natural wood?
