Driver side under carburator. What part is this? It's leaking oil

Got the exhaust system home after a very nice drive along 7 to Carlton place, and back home to the Kawartha's, north through Arnprior, Renfrew and Bancroft. Beautiful scenery, some eastern towns not yet seen, and the roads were actually pretty quiet. System is in very good shape so it seems to have bee...

Hi all, I have a 1965 standard (3 on the tree) I have a clutch question. When I start out in the morning the clutch engages quite nicely but as things heat up it tends to shutter going into gear. The whole car vibrates quite intensely. When I increase the RPM it overcomes this but its not really what I want to...

I need to have a concours quality rebuild of my Quadrajet carb. I've been looking online but can't seem to find out who is who in this business. There was a company called Carburetor Rebuilders on Eugene St. In Oshawa. Are they still in business and recommended? There is also a company in Oshawa called...

I had my engine built in 2006, and chose an entire valve train from Comp Cams. I actually picked it up from Year One just outside Atlanta while in the area visiting family. From the start I had weak vacuum, resulting in non-working power brakes. I've tried a few things, including changing the intake...

Say good bye to my "Dorky little pipe" This week I am upgrading to dual exhaust from the current low flow system. I have been told that this new free flowing system may not agree with my carburetor settings. I'm looking for thoughts from those whom had experience with a 2 barrel, dual exhaust set up. Th...

These things always get a bad rap. I rebuilt it with a new thicker shim, pivot pin and adjusted it just right. I'm not ready to blow up my 427 if I miss a gear but tonight I had the urge to do what I said I'd never do to this car, powershifting, just not at full throttle...

My V-shaped drive belt broke today, lucky I wasn't far from home. Will try to buy one tomorrow morning if stores are open otherwise will have to wait. I wonder should I leave 1/2 or 3/4 inch deflection? I don't want to put it too tight nor too loose. 67 Parisienne V8 with a 305 from a GMC pick-up instead of i...

So my 327 build has been sitting in dry heated storage for about 8 months now after having been run in on the stand for about an hour. Block drained of water. I've been thinking about it. Should I pull the plugs, give the cylinders each a shot of storage oil and crank it over a few times? Maybe until I see some...

I was fortunate to own a 66 Pontiac grande pariensene with an original 427 390HP in the late 80's. Like a doppy kid my desire was for the motor, not the car. In 1988, I pulled the 427 out, installed a 396 in the car and sold it to a guy who took it to Fort McMurray and have since heard the car is in Banff? The 42...

I am looking online to try to find the correct air cleaner decals for my 66. I can find the "Pontiac 427" decal but underneath it would be a"JET FLAME 427 390 HORSEPOWER" and it appears nobody reproduces that one. Has anyone ever seen the Jet Flame decal reproduced listing the 390 horsepower? I can only f...
