    1968 300 Rear Main Seal Leak

    Dang, guess my google search skills need work! I ordered the sneaky pete, will be here in a couple of weeks. Will report back with my results. Cleaning it all up once the seal is out will be another fun challenge!

    1968 300 Rear Main Seal Leak

    Finally decided to tackle the rear main seal leak. I removed the steering linkage and was able to lift the engine a couple inches to remove the oil pan. After removing the rear main seal retainer I found the bolts used were too long which cracked the retainer on both sides. Now I am trying to...

    Headlight motor

    In my first post of the thread below you can see the brass contacts of the "limit switch" that basically tell the motor to stop running when the doors open and close. I was able to bend these back to a working position and resolve the issue with new plastic gears. Headlight Cover Motor Repair

    Headlight motor

    Definitely could be a ground issue as @Big_John stated. In my case, the limit switch inside the motor stopped working which lead to the plastic gear getting stripped because the motor kept trying to close the doors after they were closed, which sounded like knocking inside the motor. If you...

    Transmission gaskets.

    Yes, great point. On the second attempt to repair the leak I added UV dye and fixed the leaks from the speedometer cable, under the trans mount and around the dip stick. If you have a picture to elaborate on this rod that would be awesome. That said, I don't want to hijack this thread just...

    Transmission gaskets.

    My experience with my '68 300 has not been great when it comes to the transmission pan gasket. I have had the pan off several times to try and stop the leaks from the gasket. Cork, Mopar rubber, cork with a light coating of silicone, Mopar rubber gasket with silicone. Every time it has...

    A lil ? 68 300 with a 70 383. Needs tlc

    Nice ride, love that color combo! If you want to do something in a small budget maybe consider starting simple with an intake and a four barrel. Or, if your skill set allows, maybe you can find a 440 from a motor home at a junkyard and drop it in. I would also consider headers but they seem...

    68 Polara HEI Conversion

    When I rewired my engine compartment I deleted the ballast resistor and replaced the coil with an MSD High Vibration coil which allowed me to mount it on it's side in the same location as the one it replaced. I mounted the GM HEI module to an aluminum heat sink with thermal paste using one of...

    How crispy do you like it?

    I recently removed and refurbished the wiring harness in my '68 300, including the engine harness and the dash harness. Some of the connectors looked okay but most of the wires and connectors had corrosion that required replacing. Based on the picture you posted of your ammeter, I wouldn't...

    '68 300 Stock Rims, wider tires

    @straightjob Thanks for confirming! I have put a little over a thousand miles on the old girl since bringing her home from your place in October and she loves to drive!

    '68 300 Stock Rims, wider tires

    This is probably the route I will go to keep the ride height close to what it is now.

    '68 300 Stock Rims, wider tires

    Awesome. I like the look of a wider tire but I also like the rims I have. I was concerned the rear wheels might rub against the fender skirts. Thank you both for your expertise!

    '68 300 Stock Rims, wider tires

    Howdy all, hope you're having a great month! I am planning to replace the tires on my '68 300, currently running 225/75R15 at all four corners on stock rims (maybe not stock at 15" but they have the Chrysler cover I want to keep). I would like to keep the same rims and go with wider tires like...

    Car lifts

    My wife's uncle has been wrenching for some 60 years and he has a portable pallet jack style lift. We used it to repair the frame on my '68 300 and it had no problems lifting the car safely and keeping it secure. When I finally do get a lift, this is very likely the type I will be shopping...

    Finally fixed power steering belt squeal

    Wanted to share details of how I fixed my belt squeal on my '68 300 440. The squeak started when I decided to replace the crank pulley which was pretty bent and had a lot of wobble. It was also a three valley pulley which didn't make sense being a Non-AC car so I decided to replace it with a...

    Gas fumes and empty gas filter. - '68 300

    Had a nice 90 mile trip with the 300 Sunday and no smell of gas so I am hopeful this issue is resolved. I did end up moving the dizzy advance back to ported vacuum. What I noticed when it was connected to manifold vacuum, it hesitated when I pegged the throttle. A few more kinks to work out...

    68 Polara HEI Conversion

    Also, what voltage is your mechanical VR putting out when running at idle? At cruise speed? Over voltage could definitely be problematic.

    68 Polara HEI Conversion

    Good question, I don't know. On my Fury I did not convert to HEI. On the Chrysler I converted to HEI and the GM alternator at the same time and haven't driven more than a few hundred miles. If you can convert to a solid state electronic VR or go with the GM alternator with one built in, it's...

    68 Polara HEI Conversion

    I tried parts store electronic regulators on my '68 Fury and after three failed attempts I converted to a GM 1-wire alternator which has the VR built in. One heavy gauge wire from the alternator to the battery. It worked very well. I did the same on my '68 300, replaced with a 1-wire alt, and...

    Gas fumes and empty gas filter. - '68 300

    Intake reinstalled with new valley pan with the exhaust crossover blocked off. I followed the fel-pro instructions on the install, silicone gasket maker on the ends only, used all four paper gaskets for the intake ports. After a 20 minute drive there seems to be no oil escaping around the...
