67 Caprice-2 issues
I bought the car last night and drove it 150 miles home without issue. 283 with a Rochester 2bbl. It had the front end entirely rebuilt, new shocks and tires. It rode beautifully................
1. If you mash the pedal it will bog down and stall. Once above 2500 rpm it's fine. It does the same whether cold or hot. There is a vacuum line on the front of the carb to the advance on the distributor which is new. There's another vacuum line on the rear of the carb going to the canister on the firewall. I replaced both lines as well as the large hose to the canister. Do I just need a carb rebuild kit?
2. The car uses ALOT of oil, about 2 quarts in 100 miles. It does not smoke at start up or idle, but there is oil smoke with hard acceleration when driving. There is also oil smoke in park AFTER getting on the gas as it idles down. There is no mist coming from the exhaust and no leaks anywhere, and when driving at low/mid rpm ther'es no smoke either. I haven't pulled a plug yet, but I'm sure it will be covered in oil. I haven't done a compression test either, but the car is making decent power, just not off idle due to problem #1. Is there supposed to be a PCV on this carb? It looks like may have been added later on (it's on the rear of the carb near the choke plate). Also, there is no vent tube to the stock air intake. Should there be?
Thanks for any help guys, I want to have this running tip top before tackling the body work.
