Engine problem. Sell truck, rebuild/replace motor?

The knock could have been the tensioner banging its stop. How does the harmonic balancer look? Any wobble in the outer ring? That ol flat tappet cam needs high zinc oil. 10w-30 Valvoline VR1 would be my best suggestion.

That's what I use in all my flat tappet motors, good stuff!

In a pinch you can run STP in crappy low zinc oil just have to be diligent with your oil changes,that stuff will sludge up an engine if you let it get too dirty. I've read there are zinc additives that will help the modern oils,I'm not brave enough to try it.

I'm glad to hear you found the source of the knock and corrected it. Drive easy.

I wouldn't look a 10k gift horse in the mouth!!!
If my woman gave me the go ahead and do it, I don't care if it was a unplugged spark plug.... I'm dropping a new motor in!!! Lol

Agreed, that would go a long ways toward whatever motor you want to swap in it!

When I had my '88 C2500, getting a crate 4-bolt main, 350, was the option, with 220,000 on the clock. I needed to rebuild the heads, but my 'race' mechanic suggested a crate motor instead, since the cost was not much different. I spent a week just cleaning up stuff, but installing the new engine only took a weekend. Back then, his cost for a crate 'long block' cost less than $1,500 !!

I actually purchased the engine through PepBoys ( They were the distributer.... not the builder!

Best choice I ever did!

My beloved '92 Sport (162k miles) has developed an engine knock. I put in new bearings and oil pump, but the problem has returned. I think the connecting rods are too worn.

Here's my dilemma. I live in a rural area, so rebuilding is not much of an option. I can probably get a crate, but that will eat up close to 10 Grand.

With the engine running, I think the truck was worth about $20k (it's in spectacular condition, I'm original owner). What is a ballpark value of the truck with engine needing a rebuild/replace?

These trucks are not going down in value! Is anything wrong with the top end? Sorry I didn’t read all the posts. But anyway, order a short block if the top end is ok. You should be able to find a good mechanic to do the swap out for under $2000. They will cry and moan about it but you can do it!
It’s too nice a truck not to.
