Problems: low oil pressure lamp will come on when vehicle is hot and idling
rough idle
smells like car runs rich

Timing: 9degrees(set with vacuum advance off)
Factory spec:7.5 degrees
Spark plugs: Autolite one heat ranger colder than recommended(because the plug Champion,Autolite,AC,manufacturers decided to only offer colder plug for 63s skylark)

I have 215v8, which I'm reading vacuum reading from the carburator. I have gauge attached at the vacuum advance pipe feed(on the carburator), which says 4-5Hg. WHen i rev it vacuum goes up to 20-25Hg
/in. of mercury.
There is a discussion of ported vacuum. I have 4gc rochester carb. Ran out of time to go back and check vacuum at PCV port.

I feel the engine runs rough, which it does. when engine was rebuilt no camshaft was replaced. Compressions range 140-150 on all cylinders.

Fix:After researching, I will install a Crower 50228 in next few weeks. I don't work for Crower, any other camshaft suggestions I will welcome it. I will lightly port the heads at the same time.

I'm aware old cars run rich, but really? I woulld like to know if anyone has the emmissions test on their car. I want my car not to run rich. Is it unburned Hydrocarbons,Carbon Monoxide,Nox, I'm smelling?

Oil problem might be that the rocker shafts are assembled incorrectly.
Fix: I have a new pair ready to go.

What do you think?

If your low oil lamp is coming on then you have no or very little oil pressure. Don't run it until you figure it out. Maybe it's a problem with the light or the sender, but you need to determine why you have no oil pressure before anything else. I don't think the rockers would have anything to do with that...it could be a faulty oil pump, excess clearance in the main and rod bearings, or ? Did the low oil pressure start happening all of a sudden, or has it always been like that?

I don't know if 4GCs had ported or manifold vacuum, but 4-5 hg/in is extremely low, like vacuum leak low. Are you timing it with the light connected to cylinder #1? Sometimes the balancer can slip and you can get an inaccurate reading, but at any rate the timing would have to be wholsale off to give you that low of vacuum. If you have a huge vacuum leak, it would cause the rough idle and the low vacuum...start looking for a leak...but first, get the oil pressure sorted out! Good luck!

I agree with Aaron, you probably have an oil pressure problem to sort out first. Go back and look at your invoices for the rebuild and see if they replaced the cam bearings.

You probably do have ported vacuum which is why you have a low vacuum reading on the advance port. This is not right either, but is often caused when an engine is running poorly and someone turn the idle up partially exposing the port.

There is no good reason for the engine to run very rich other than it is out of tune which is indicated by the advance vacuum port. Your distributor probably needs someone to go through it.

thanks machine shop
now the light comes on for a second at rare occurrence,
so i will change oil after 100 miles and try again.

removed rocker shafts, found torn valve stem seals and some unseated.
engine rebuilt 10 years ago, about 900 miles since
I've been researching crower 50227 or 50228. difference is valve lift and power range shifted higher. i want stock performance. I've already heard it all, go bigger, blah, blah blah:coo:

This is plan: lightly port heads, new camshaft, 30 and 45 degree valve cut, good valve stem oil seals.budget $200-350
I'm doing teardown and build need good machine shop in Culver city,ca

yeowtch.

I seem to have minimized low oil pressure problem to almost never occuring. I have 4in. Hg vacuum at idle. It is a solid steady needle reading. I did notice that the idle increases as the car warms quite alot.

I took the carburetor base plate off, inspected gasket. refit. retorqued bolts. I did the palm over the carburetor intake test(check for vacuum leak test). The idle didn't go up.

ANYONE'S 63 RUN LIKE THIS?










(I have come across a website partsamerica.com that seems to have: Dashpot Standard Motors #D538R, carburetor kit, camshaft AE Clevite #2291364, cylinder sleeves. Rocker arm shafts AE clevite #2303020)
