Are fumes avoidable?


Hey fellas, long time, no posts! Took the '63 out of hiding the other day, and wouldn't you know, it fired up with minimal coaxing. Topped up the fluids and put air in the tires, and was good to go. The only rub is it was a little smelly inside the cabin. Since I run my exhaust straight out the rear bumpers, I'm thinking it's oil fumes coming out the valve cover breathers. Is this avoidable, or just part of the charm? Was wondering if a 70's style closed pvc system that vents into the air cleaner is worth pursuing. Just trying to keep it fresh! Any opinions and knowledge greatly appreciated. Thanks!

Mike, getting the same thing on 64!!!! Think your 63 has the "stink" tube going down the back of engine??? Mine has a PCV where tube was on yours going to air cleaner. going to check it too see if it's stuck. possible yours may have a leak there? I think I saw a conversion kit available but can't remember the site, try google, pete

Thanks Pete. I'm pretty sure the road draft tube was surgically removed before I got the car., because there's a pvc valve hanging around in that area. I'll give it a once over. Thanks

Fumes and mould smells are the rewards of driving old cars biggrin  Back in the 60's everyone was filling lungs with cigarettes, so those smells weren't noticed

I have had some exhaust fumes come from the manifold to front exhaust pipe where the ring seal is. Just tighten up the 9/16 nuts and you have eliminated one smell.

63 was the first year with a complete factory PVC setup, no road draft tube.

If you don't drive them much, any leaking oil will burn off when you drive. Gaskets have a service life, and with a ton of heat-cool cycles they can start to shear. Enter leaks.

63 was the year that the open PCV system was used federally & in Canada, replacing the road draft tube. In California since 61. 66 CA went to a closed PCV system. It actually started in the 1940s Step Vans because of the confined set-back engine quarters.

Check your trunk seal/weatherstrip. Not the same car (57 Chev) but chased a exhaust problem in the cabin for years (15)!!!! Have rear/bumper exhaust and would always get exhaust smell in the cab after an hr of driving. Checked everything...even 3 diff types of manifold gaskets. Last set helped but stink was still there. My wife got to the point that she wouldn't even ride in it if going on a long cruise. Tightened up my trunk latch by 1/8 of an inch....no more stench!!!! Air turbulence in front/behind of rear bumper can cause a lot of headaches(not just from fumes!)!!

My 60 Catalina had that "stink tube" at the back of the 389. Every once in a while I'd get a whiff of it in the cabin and when it occurred I was instantly transported back to my childhood when we'd be sitting in traffic on a hot summer day bathing in fumes.

Don't worry fellas, I'm not expecting Prius level emissions. Just trying to dial the smell towards nostalgia, and away from itchy eyes and a sore throat. Gonna try a closed pcv system on the valve covers, venting any blowback and fumes into the air cleaner. Wish me luck, cough cough.

Do you have the closed oil fill cover or the one that breathes?The closed oil fill tube was like this, if your car has this, there needs to be a tube from your carb to your breather.

What motor, carb and air breather?

Be careful installing a PCV in the stock valve covers, without a baffle under the cover/pcv, they may suck oil off the lifters directly into the carb.

 

This is stock, Show Cars sell it as a set.

Good info in this thread.  There's a reason that emission controls have become so stringent over the past 50 years - all those fumes are not good for us and will take its toll on your body over time.  It's a great idea to try to control it as much as possible, nobody wants to end up causing a health problem to themselves or their kids from breathing in all this stuff on a regular basis.

remember lead, that's all stored up as deposits in a original motors, when it heats up and vapourises in a crank case it gets blown out into the atmosphere and into your lungs or your kids. rebuilding gets rid of all that gunk and seals a motor back up, and the old style closed pcv reburns some of that gunk that we know is not good for us.

Don, I've got the breather in the oil fill tube, and breathers in both valve covers, so plenty of ventilation. It's a pretty stock 283, from 66 or so, with original intake and 2 barrel. Currently sporting some tall chrome moroso valve covers, with baffles. Also have a set of vintage M/T covers that I may swap out. Waiting on the shelf is a quadrajet and edelbrock 2101 intake. The intake doesn't have a oil fill tube, so I may keep the pcv in the back, and run fresh air from both valve covers to the air intake. Engine is running strong and healthy, just the occasional waft leaking into the cabin. I've got young kids along for the ride, so I'm trying to keep the harmful stuff at bay. Thanks everyone for their input and opinions.

A little exhaust smell once in a while won't hurt you. My grandson at 2 1/2 was out with his mom and smelled some exhaust from an old vehicle with no cat, he said "I smell grandpa". I have a ride on mower, an outboard, an old 2 stroke, and the old car.

You can check your firewall for holes/leakage. Just check it with a light in the dark and close any holes. Plus, make sure you have no leaks in your exhaust system. If your pipes exhaust on the side, you may also get a bit of a smell when driving with the windows open.

On the configuration in the photo, could you tell me where the 2 hoses go,..

The hose coming from the oil filler

The PVC hose from the back of the engine.

If I remember correctly, the one from the back of the engine goes to the PCV valve which screws into the back of the carb. And the one from the oil filler tube goes to a vacuum connection tee located  towards the rear of the intake manifold. Is this correct?

No knowledge of a 66, but the 63's with the nipple on the oil filler were connected to the bottom of the air cleaner and you are correct on the other one.

the hose from the back of the engine goes to the air cleaner to a nipple and flame arrestor in the air cleaner, the hose from the oil filler , could have the pcv mounted in the oil filler or on the back of the carb depending which is easier to find and you cannot substitute one for the other they are different , this set was scam from corvetts 65 and earlier.

 That's backwards to the setup on  my 63 Corvette and all 63 Pontiacs and Chevies. The PCV was always at the back of the carb and no PCV on the hose between the oil filler and the air cleaner.

 the idea is to close off all fumes coming out of the motor, the engine draws fresh air in through the aircleaner and pulls it out through the now caped oil filler it doesn't matter were the pcv valve is located as long as its the proper unit , I was having trouble finding the ones on the carb and found a supply of the one mounted on the filler tube.
