Discolored Pushrods?

Been slowly getting around to making the truck road worthy, I only get time with it a few weeks a year. I pulled the carb and intake off (preparing for a swap) and noticed discolartion of the push rods. Is this something I should be concerned with? Truck sat for about 5 years without being started until about 6 months ago. Any help would be greatly appreciated!

Re: Discolored Pushrods?

Looks like varnish and crud build-up on the push rods. Rest of the engine looks pretty dry and free of deposits. Have you cleaned it?

Looks normal except #1 exhaust and #4 exhaust. They are much darker....

Re: Discolored Pushrods?

I have not cleaned it, just soaked up what little coolant spilled in when i removed the manifold.... I bought this engine with a "parts truck" and the PO stated that it was a rebuilt engine when I purchased it in 08. If it doesn't look like there are any more concerns, other than some pushrods/oil change, I'm going to pull the trigger on the manifold/carb kit.

Re: Discolored Pushrods?

They aren't discolored. Look Normal to me too. But if you're concerned, replace them. Decent pushrods are cheap.

I'd only worry about them if they were the wrong size or bent.
