What is the normal sound of the engine?

Post by SpookyDad »

What is the normal sound of the engine at idle? I hear a ticking, that to me, could be a bad rocker or perhaps a sticking valve. It isn't loud but I don't have any reference to go by.

Could be that or an arc

Take the valve cover off. Put a .015 feeler gauge between each rocker and valve one at a time and see if the "ticking" goes away

my engine ticks a bit

an old mechanic who listened to it told me that the valve lash needs adjusting.

cause i have never adjusted them on an engine such as this, as outlined in the manual, with the motor running, i feel a bit nervous, for some reason.

are there any other tips, or precautions one needs to take before doing this job.

i obtained a replacement rocker cover gasket ages ago, so i could do the job, but just have'nt got around to it

maybe just need some inspiration!

what is the outcome of not adjusting them?

I have had the vehicle since 2000, but only done a few hundred miles, but they may not have been done for some years before that either

A friend made another video of my truck recently. Here you can hear the engine very well. I don't think it needs adjustments. Sounds very smooth after one or two minutes, when the engine is warm:

The VERY 1st thing!!!!!!!!!!!!!

Clean the valve cover gasket area on the head with brake clean or something and glue the gasket on with Permatex gold cement. Use the valve cover to position it correctly. If you don't do this, you will have one awful mess in the engine compartment due to the head being flat and oil just running down the sides of the engine. DO NOT glue the gasket to the valve cover, just to the head.

You must make sure the engine is up to temp. That means running it for a long time, like as in more than an hour.

It is not difficult to do. Run the idle down as low as you can. That will help a lot. Buy a tool or find the actual WW2 tool if you can. It is easier that way. Read the manual.
