    Its better to find that mistake now than at the 4 mile mark on the odometer. I read an older post from a motorhome forum. They were using caddy engines too. Ine guy did the same thing. Lifters popped out when the rockers failed. Very costly mistake on his part. My heart sank when i read it. Stay encouraged. Your doing it right. I remeber Mad Cadder telling me" it costs what it costs and its cheaper to do it right the first time"
    Thats why i choose to go with the 15 cam ect. Your ride is very nice and your attention to detail shows. Thank you for sharing. I enjoy reading everyones posts on there project. It keeps me encouraged too. We got alot of great folks here.

    Wow, that work looks great!

    Not sure if I missed it in there, but don't forget some heat shielding between the tail pipe and tank.

    You didn't miss it! It's actually next on the list. A thin sheet of aluminum running the length of the exhaust pipe should do the trick right? I need to pull the tank back out to wire up the sender, so I'll find a nice spot to bolt up shielding while I'm in there.

    Sounds great.
    My 69's had a factory shield on the driver's side. Might be something there?
    Tank was offset so I hadn't done the pass. side yet.

    Thanks PJ, I am! I'm also extremely excited to get this thing on the road. It's been way too long since I've done a burnout. lol

    Hi everybody, still waiting on back-ordered parts over here... Seems to be a consistent theme with this build. In the meantime, I've been doing some thinking under my bucket. Having read some of the recent comments about the oil system on these motors, I've decided the cheapest and easiest form of insurance is going to be an oil accumulator. I'm going to run this one from Moroso:

    http://www.jegs.com/i/Moroso/710/23900K/10002/-1

    These things are pretty cool; they use air pressure to force oil into the engine under extreme conditions like hard acceleration, hard braking, and fast corners (sounds like my commute). The kit comes with everything but AN line, which I have plenty of. At first 500 bucks seemed steep, but after some deliberation it turns out that $500 is better than a motor burning up.

    Here's my tech question: Where do ya'll think is the best spot to hook up the -10 line that runs from the accumulator to the engine? They recommend hooking it to the oil cooler circuit, but I don't have one of those. I perused Cadco's website just now, and saw that they sell a "sandwich style" oil cooler adapter that fits between the filter and the pump. I wonder if something like that could be used? The oil travels both ways in the accumulator's -10 line, so I wouldn't need the second port on the oil cooler adapter. I'm just a little baffled (ha-ha) by the oil flow direction, and I am in need of some experienced re-assurance that I'm on the right path.

    Hope you guys are doing well!

    -Nick

    Haven't used an Accumulator on a Caddy but right above the oil pump there's a pipe plug.

    I think I'm familiar with that pipe plug. If we're thinking about the same thing, that's where I've hooked my -6 balance line.

    What vehicle(s) do you drive?:
    1964 Commercial, 1948 Austin, 58 Pan
    Just cheaper and less hassle to get a new tank and sending unit. Will have to check on Mon. for the Co. This guy even has tanks and sending units for commercial.

    Hey folks, I mentioned in my pervious post that I was considering an accumulator to save my butt in low oil pressure conditions.

    And voila, here we are. Bear in mind, I’ve never done metal working in my life, but a simple set of L brackets seemed easy enough. They aren’t perfect, but they’ll work. Just 1/8” steel knocked in to shape with a hammer.

    After some quick research, I’ve decided to tie this accumulator into my oil cooler lines. I’ll be using -10 AN line, and a sandwich style oil cooler adapter from Cadco. B&M will be supplying one of their Universal Super Coolers. I’m going to order up the rest of this stuff by theweekend and hook it all together. Still waiting on B/O parts to get the engine running. Not much I can do about it.

    Thanks PJ, I've been having a great time and hey, not so bad for my first effort, right? The deeper I go, the longer the list gets. Suspension and bodywork are my 2018 to-do's.

    that fuel tank is damn right beautiful....I have a boyd tank for my truck. Did they have a plan for that 68 tank in house, or did you have to send an old tank to them ? I may need one of those one day...
    the one thing I am surprised about is the sump is up front facing forward...seems it might get uncovered under hard acceleration and low fuel. But maybe they baffled that area real good ? putting it up there cleans up the lines and tucks it nice though. My sumped stock tank has it in the back, and you can see it standing behind the car as it sticks below the back bumper.

    Hi Andy, thanks! I'm very happy with the tank. I actually drew my own blueprints for it, and I attached them here! Sideways, I'm afraid, but you get the idea. The mounting tabs line up so that the tank bolts directly to the two support beams running parallel from front to back in the trunk of 68's. I used a couple of rubber bushing to eliminate any vibrations, and it is a very sturdy setup overall. On the blueprints you can see where they placed the baffling, I think it should be sufficient in keeping the fuel where it needs to be. Having the sump upfront also simplifies the routing of the fuel lines. Osgood Custom Tank Revision-page-001.jpg Osgood Custom Tank Revision-page-002.jpg

    Hi everybody, I got some time to get out in the shop this afternoon. I made some worrying discoveries. If you'll remember, I have a similar problem that Caddy Crosley is having: the engine stumbles slightly and a mist of air an fuel is blowing out of the top of the carb. I've got air, fuel, and spark; but no start!

    I pulled the cap off the distributor and I pulled the valve cover off of the #1, 3, 5, 7 cylinder bank (passenger side). My plan was to verify that I was at TDC with cylinder #1 on the compression stroke. Usually I stick a long screwdriver gently into the spark plug hole and use that to watch the up and down movement of the piston. I also keep an eye on the rocker arms to make sure that valves are closed as the piston is traveling up the cylinder. This is where it got weird.

    I was turning the engine over by hand, watching the screwdriver come up out of the spark plug hole. The timing marks on the pulley were coming around as well. Just before the engine reached TDC, the exhaust valve started to open up! The exhaust valve stayed fully open as the piston started on it's way back down the cylinder. It reached the bottom, and as it began to come back up, the intake valve opened! Thinking I was just rotating the engine backwards, I checked by bumping the starter a few times. Turns out, I was going the right way: counterclockwise when sitting in the car looking over the hood, or clockwise when standing in front of the car facing the engine. Could it be that my valve operation is somehow reversed?

    I have no doubt that I made a major noob mistake somewhere during assembly, I just can't figure out what it is. Could the cam be installed incorrectly in relation to the crank? I am at a total loss and I'm considering taking it to a shop. I hate to give up but I don't want to break something this expensive.

    Please help, I am in dire need!
