I have a 283 in my 1963 impala, im new to the engine rebuilding. Under the intake there is a small canister by the distributor what is it? And can I remove it? I bought an after market aluminum intake and it wont fit with it there. Tried posting a pic of it but had no luck. Any help would be awesome.
It's a baffle for the road draft tube. If you take it out, you need to plug the hole and install a PCV. Edit: just noticed you have a '63 so it has a PCV. Still, if you remove this thing you should probably relocate the PCV to a valve cover.
It's part of the draft tube or pvc system. If you remove it it will blow oil if you have a draft tube or it will **** oil if you have a pvc. Sometimes we used to get away with beating it down a little for clearance.
Figured out how to DL the pic, so just unscrew it and plug the hole with a plug then add PCV to the valve cover does it matter which one?
Doesn't matter which cover but typically they are on the right bank. Also, some had road draft tubes some had a fitting with a piece of rubber hose on it...this is whats on my 283. Tim
You should either get a valve cover with the PCV hole in it or weld a little baffle in yours so the PCV doesn't **** wayward oil flying off the rockers.
Take the screw out and knock the canister out.It's pressed in. Just plug the outer hole and add PCV system.
Don't forget that after adding an aluminum intake you will not have the oil fill tube. This also serves as the way to let fresh air into the crankcase. You can add a breather to one valve cover and hook up a pcv valve on the other valve cover. The easy way is to use later model valve covers which already have these. Just copy the way the factory did it in the late 60's.
Might it be easier to grind some clearence into the intake? Then you can leave everything else as it is.
The easiest thing to do is get an intake with a fill tube, then you won't have to reinvent your wheel and it will still look like a vintage engine. If you remove the canister so your intake fits, you'll need valve covers too, then rearrange your PVC , adequate baffle, and the rule of " there's never just one change" will apply well here.
How bad is it hitting? I read here on the HAMB where a guy took a BFH and dented the canister until it did not hit anymore. It won't affect the air flow for all the scientists out there As far as the fill tube in front of the intake many have a flat spot that is easily drilled out to accept the fill tube. readily available from any chrome accessory shop
