Chevrolet s10 4.3

It was a good idea, then I don’t have to be so careful.

Wait!! I got this very special recipe for RED paint that requires iron oxide and linseed oil. Since the iron oxide is already present, you just need to hit it with boiled linseed oil (or just a clear coat). People pay big bucks for the ‘vintage’ look paint jobs. It is hard to make them look authentic. :slight_smile:

Now I’ve tried engine cleaning, additives for valve knock, and something to make the oil better, still knocking, can’t hear where it’s coming from, I think it sounds a little more on the right side from the front.
Is it something to be concerned about?

Hard to hear with the other engine noise but if it’s the tick tick sound I think I heard then it’s a stuck or pumped up lifter. Seems to be a common problem on that engine. At lot of supposed fixes on you tube. I’ll post one and then there will be many more on the right side of the page.

Jan, I don’t know if it’s relevant to what seems to be a continuous condition, but I suffer from some valve ticking too from time to time. I’ve come to believe it has to do with a chunk of soot letting go and interfering with an intake valve. This usually happens when I’ve done many cold pullstarts in a row and probably some tary fumes. Any soot in the throttlebody area will get a wet surface and heavy enough to let go.
It never happens during winter though - moisture related, I think. Relativly dry and cool air will make less and catch more moisture before it enters the motor and less soot will accumulate in the throttlebody.
I find any ticking will fade away with some reving when the motor warms up and the valves will grind down any chunks of soot towards the seats.
It’s been especially scary with the 3 valve/cyl Mazda interference engine, but I’ve come to the conclusion that I can’t do much about it other than using as dry fuel as possible and try avoid frekvent pullstarts.
