Good morning,
Newbie here. Know nothing about engines. 1975 Chevy k5 Blazer V8 350 has been sitting for a few years without being started. To get it started i have a new battery, I checked the engine oil level and topped it up and in the carbeurator float I added gasoline to get it to start and engine sounded fine. Vehicle has been parked inside a dry garage the entire time with no temperature control/
After I started the vehicle I had to drive vehicle out of garage due to so much exhaust (no smoke) down a bit of a hill maybe 10 feet . Left it running a few minutes. Then had to reverse back up hill into the garage. I may have left the parking brake on while doing this. So truck wasn't reversing and I was giving it some gas. Realized the parking brake was on and released it then was able to reverse back into the garage which is level.
So after stressing out the vehicle there was some burning smell and bit of smoke from the area where the spark plug wires are.
So, did i damage something? Should I even try to drive vehicle after this occured? Concerned about overheating the vehicle.
The engine does leak oil slowly over time , from where I do not know.
I plan on starting it again next week and driving it a bit to see if the smoke returns.
Thanks for your help!
Sylvia
 
There’s probably some oil dirt, dead mice, and a few other choice. Things laying on the exhaust that have been sitting there since it hasn’t ran for so long. Not in common to smell some weird burning things, just make sure that you don’t have flames fire, pile of dead leaves. I wouldn’t fuss too much over the brakes driven down the road with them still on.
 
Yeah 10 ft on p brake no worries we have all done that a time or two.
20 miles down the road then its a problem.

Burning smell is as bent77 said old oil dust etc, valve cover gaskets may be in need of replacement
 
Congratulations on a running and driving truck. If all you have is a little burnt smell you are way ahead of most projects that have sat for even a few months. As mentioned above the exhaust manifolds by their shape seem to catch everything and a lot of those things caught tend to smell and smoke.

Verify no fluids of any kind are dripping from the running engine, have a fire extinguisher just in case and go for a drive. Getting above 45 mph and cruising will burn everything off after about 5 minutes. Pull over after 5 or so miles and give everything a look over. If all looks well, enjoy with less anxiety. If not, let us know and the collective knowledge here will help you out.
 
Thanks everyone I’m gonna go ahead and insure the vehicle and get it in the road and I feel a whole lot better about doing that with everyone’s advice!
 
Well, guess who’s driving the blazer around? I am !! thank you for all the advice. I really appreciate it . Running good so far.!! I will definitely look into the locking dipstick because I don’t have one, I do carry a fire extinguisher, just in case.
I will tell you that your truck has the same transmission dipstick that millions of other older vehicles have used. Every domestic vehicle made in the US had something identical or similar for decades.
The locking ones showed up in the early to mid eighties on GM vehicles.
They have a lever on them to squeeze the rubber end seal a little.
As long as the transmission vent isn't plugged and the transmission is working well, the dipstick should stay in fairly well. Not saying that it can never come up out, anything can happen.

Even if the transmission is overfilled and then the oil gets warmed up good, it usually comes out of the vent on the top of the transmission case back. If that were to happen, it can get onto the exhaust. That I have seen happen and it can lead to a fire, just not always.

Safety is always good.
