    R134A Conversion for Factory Air Conditioning

    All good advice. I will add one more item. As soon as the receiver dryer is open to the atmosphere, and this includes the new one, the silica gel inside starts to absorb moisture. That is what it is supposed to do. If one wants to make sure the silica gel has released all of its moisture and turned blue ( not that you can see color inside that metal can๐Ÿ˜‰), pull a good vacuum on the system, then pace a heat lamp, or even an incandescent drop light (remember those?) near the receiver dryer to get it warmer than 212 ยฐF. Not much warmer, do not melt anything!๐Ÿ˜ฒ Leaving the system under vacuum for overnight (not with the vacuum pump on or heat on anything) also helps the moisture evaporate out of the silica gel. Then next day, turn the pump on and suck the evaporated moisture out of the system. If one has a tank of nitrogen, that is also a good way to remove the air from the system after running flush through it, or just having replaced parts and the system was open. Also nitrogen is a good way to pressurize the system to leak check. If using shop air to leak test system, use the driest air possible, like air already run through a silica gel tank or refrigerated air dryer. If you flush the system, make sure to add oil.

    To resonate or not?

    Or you found the X-Files section of the Expressway!

    To resonate or not?

    Bernie, neither my 94 Caprice wagon or the 96 Roadmaster wagon do that at full throttle. Look for a vacuum leak in the heater controls, or a bad check valve on the reservoir.

    Borg Warner DG250 Locking up

    I agree, change the fluid. I say use modern ATF of the Dexron lineage, since literature of the time lists Type A as the fluid to use, which morphed into Dexron. There are some who say use type F. Probably makes no difference at the moment.

    Pre-war paint question

    I've seen gasoline hurt paint on several cars, but they were repainted, not OEM finishes. I've even seen gasoline stain Urethanes. BTW, here is a great history article written for Body Shop Business. Studebaker used Alkyd Enamel.

    Tax and your cars

    I'm with Joe, Joe is spending more in gas tax than the owners of new SUVs for the same miles driven, even though Joe' Oldsmobiles weigh less than the SUVs. Don't believe us? Read driving reviews of 64 to 74 Oldsmobiles and then read the reviews of 2010 and newer SUVs. fuel consumption and mileage: average estimated by a-cยฉ: 23.9 l/100km / 11.8 mpg (imp.) / 9.8 mpg (U.S.) / 4.2 km/l, more data: 1964 Oldsmobile Super 88 Celebrity Sedan Hydra-Matic (aut. 3) Specifications Review 2010 Chevy Suburban MPG: 15 city / 21 highway

    Pre-war paint question

    Alkyd emanel was the other auto paint back before Acrylic paints (lacquer and enamel). Was that the Studebaker driversโ€™ club or the Antique Studebaker club?

    Mass. YOM plates and new inspection rules

    Rusted frames, rusty bodies/exhaust system to let carbon monoxide into the passenger compartment, worn brake parts, worn suspension joints, burned out lamps, tires with no tread or damaged spots to make blowouts, etc, etc. Here you go: Not to strike up controversy, but here in Virginia we say just look at the Maryland cars driving around here to see the value of yearly safety inspections. ๐Ÿ˜‰ We do have the "self inspected" rule for vehicles sporting Antique plates. You sign a document stating the car would pass safety inspection to get your permanent plates.

    Another "Why I Love Craigslist" Car

    Snow is not a problem, just solid form of rain. Old cars in the snow actually look good. It is driving them in snow with salt treatment on the roads that is the car killer of the east. I got the humor right away, Woodsey. ๐Ÿ˜

    And the full deduction is 2 points per tire! Are we now discussing if the correct tire is unobtainium the deduction should be different?

    Engine scanner

    And also ask about the repossessed tools on the truck. Also sold at a heavy discount with in place warranty. I bought my Solus Pro, it was a trade in.

    Engine scanner

    That was the very old Red Brick, MT2500. Coverage of the MT2500 cartridges stopped for most models by the early 2000's. Then, because most of the MT2500 use was on OBD 1 vehicles, and every manufacturer had a proprietary connector, you needed a box full of adapters a profile keys to connect to the vehicles. All the newer Snap On scanners are just software modules you buy. Usually you find the newer ones already have the Domestic and Asian packages inside. And then of course pay for the upgrades to get newer cars read.๐Ÿ˜‰ Oh, and keep that box full of adapters and keys if you still want to read OBD 1 vehicles! Friends seem happy with the Bluetooth and phone scanners. I now use a Solus Pro..... having sold my MT2500 to a friend who also owns 1995 GM cars!

    Engine scanner

    If you want to do 1995 GM cars, go with Snap On scanner, as that is one of the few that will do the weird 1995 GM OBD1.5, which is OBD 1 with an OBD II connector. Even the lowly outdated red brick aka MT2500 will do this well. Now, if you mean 1996 to present, with a standard OBDII connector, most any little scanner will work. There is also the OBD II Bluetooth adapter for use with your phone! Most of these do American and Asian OBD II cars 1996 to present. Want VW coverage, that is more specialized, like VCDS. Then there is Moates . net software for a laptop that will do OBD I and OBD II. Not so much handheld....

    To pay or not to pay?...

    In addition to helping our local AACA put on the June downtown show ( and I wonder if this discussion is even talking about AACA shows, since AFAIK, they ALL charge to enter and spectators are free) I also go to a show down in Centerville, VA (Goochland County Centerville) in September, called Field Day Of The Past. Lots of old steam machinery, buildings, etc. The spectators have to pay to enter the field, just like a State or County fair, but on Saturday of the event, "they" want old cars to show up for a car show within the other activities, so the cars get in free, along with the drivers and a passenger. There is a small fee if you want to "show" the car and try for a trophy. No charge to park with those "showing". Once the car is parked, you can roam the grounds doing fun things, like watch a steam sawmill in action and sit in your lawn chair when your legs are tired. . I go every year. ๐Ÿ˜€ So, I do both, help put on an AACA show that has to charge the cars to enter to cover costs (like every AACA show I know of), and I go to a show that charges spectators and lets the cars in free. If youse guys are near Virginia, I suggest you go to both! ๐Ÿ˜‰

    To pay or not to pay?...

    I am a member of the Historic Fredericksburg Region AACA. We put on an AAA show in downtown Fredericksburg, VA every year. Coming soon, June 2 this year. We do not charge spectators, since it is held right downtown on tree lined Caroline street, with shops and eating establishments all along the street. A great venue. We do charge admission, since we do trophies and pay fees associated with a downtown show. We could not afford to put on the show if we did not charge the car owners. I understand the judging issues mentioned by intimeold. It takes a lot of judges to do a decent job to judge 200 cars in just a few hours.
