I am not too knowledgable on cars yet.
If that's the case, don't get overwhelmed by all the suggestions. You will not be able to learn everything overnight.

Most importantly, CHECK FLUIDS REGULARLY. Like once a week or every time you fill it with motion potion. Even if your truck marks it's territory with every fluid possible, it will continue to run and drive as long as it doesn't run out of those fluids.

The weeks worth of oil dripping is a bit excessive, but it isn't enough to hurt your truck while you're gradually fixing things.

Craftsman tools have a lifetime warranty so if you've got a cracked socket or ratchet that doesn't work you can take it to Ace Hardware or anyplace that sells Craftsman and they'll exchange it.

Welcome and a great vehicle to learn some things on!
Yes that’s a lot of oil.
First things first. Now it’s cold out but if you can hook a hose to a water heater it will help.
Take the air cleaner off, bag up the carb real good and soak everything in degreaser a couple times and get it all cleaned up before you go much further.
And any areas you can scrape the old buildup off or mostly off before degreasing will help as well.
Trust me on this. It will be easier to diagnose and easier to repair if everything you touch doesn’t have 30 years of goo built up on it.
Bonus if you have or can borrow a pressure washer.
Even better if you can do something to raise the truck up so it’s easier to access underneath for cleaning.

May only be one or 2 major leaks. But it will be much easier to tell once it’s cleaned up good.

That’s good to know. My grandma gave me a wrench and it barely works so I might be able to get a new one if those

how does this apply to the older variants, do they hand you a equivalent? I think I have a broken 3/8 ratchet, but its the old nice kind. so it would be a downgrade, but a broken ratchet is not doing very much either.

He could also run his engine enough to have it warmed so that if it were cold enough to ice , it would have enoguh time to drain off and aid in drying . hopefully its not freezing there. or if they had a garage with a drain in it. could also use a car wash station as long as its careful so he doesnt become stuck there from spraying something accidently

in the same vain as this, since its a recent got-running.



I would suggest the OP take some of the oil thats on the dipstick and rub some between your fingers , note how it feels. with a little fresh oil, do the same on the other hand.

Also smell it. Does it have a strangely feeling difference on the oil in the engine and does it smell like gasoline?

The reason for this is to make sure the engine isnt pushing gas into the oil in significant amounts. This will make oil leaks worse since the gas attacks seals and thins the oil.

So I have been working on a 77 K10 with my grandma for a while and we got it running and stuff a little bit ago. I have started to notice that this truck likes to leak out of almost everywhere. About a month ago I replaced the pinion seal because I found out my dif was almost out of fluid from a leak and now I am starting to notice a lot of oil leaking from what I think is my valve covers and what I think is the front seal thingy. I don’t know if thats a thing but it looks like oil is coming out of the front of my engine from the belt side. My grandma says it’s normal for old trucks like this to leak a lot but I am starting to worry about the amount of leakage. Thank you for anyone that could give me insight.

The first photo is of about a weeks worth of oil leakage. The second photo is the bottom of the oil pan and the third is right under the pulley thingy I think is what it’s called lol.

Thank you for any advice given and feel free to ask for more photos

It’s common for valve gaskets to leak. They are easy to replace. The puddle of oil is excessive. Could be front main, timing cover, oil pan and/or rear main.

Use some engine degreaser and wipe it all down as best as possible. That should help you to pinpoint the leak a bit better. Don’t shoot brake cleaner at anything rubber that looks like a seal. Ask me how I know…
Look at the front of the block. There's 4 bolt bosses where front motor mounts were used. Make sure that there's a bolt in the top passenger side. I can't tell you how many times people have brought their fresh motors in wanting their front seal replaced, and it was only a missing bolt.

Could be, but it sounds like the OPs engine is anything but fresh.

This blew my mind so of course I googled it. The below thread goes a little deeper into the leaky motor mount discussion
