Re: Cleaning headliner

Start with a mild soap and work towards more aggressive cleaners if the stains don't come out. Mineral spirits is on the scale of mild solvent based cleaners if the water based soaps like simple green doesn't work. The harsher solvents like acetone will work better, but it tends to strip the plastic...

Re: Ignition system

Greetings... I see you decided to stay with the Marelli coils. Any particular reason? Also, the white GTE Tom has been working on has Bosch blue coils. Oh the shame. The value of the car has been cut in half. This car should never be allowed on the show field. How could someone commit such a traves...

Re: Tom, impressed with your methodical problem solving

Hi Pete,

It's the nature of these old cars, but the nice thing is some of this stuff that was made back then can still be repaired instead of the parts today that often leave you no choice but to replace them.

Re: Tom, impressed with your methodical problem solving

Hi Pete, If you're referring to the turn signal switch repair: http://tomyang.net/?p=19212 Thank you. I was always happy to find a solution to problem. Anyone who works on these cars does this kind of stuff every day, so I don't think I'm doing anything different. It's nice, however to share my expe...

Re: 250 Gte Valve timing

Tom: I apologize for being "picky", but the actual minimum amount by which you can change the cam timing is 2 degrees on the camshaft which translates to 4 degrees on the crank. For every 7 teeth you move the cam chain sprocket, the flywheel moves 148 degrees 10 minutes, and for every bolt hole you...

Re: 250 Gte Valve timing

Hi Christopher,

I usually start with the factory marks as a starting point. Be very careful! If you feel something interfering, stop and check.

Jumping 7 teeth on the chain sprocket moves the cam by 1 degree. Which way? I always have to do it to remember which direction the cam turns.

Re: Ignition system

Great Job Clint. At least you'll have something to show for your time social distancing! It's better than sitting on the couch watching Netflix!

Re: 250 Gte Distributor

Hi Chris,

As you have learned the different springs allow the weights to progressively advance the distributor as the speed increases.

Re: Resistor sparkplugs

I'm just speaking out loud, so please someone correct me if I'm wrong. Electronic ignition system like the motorola boxes were basically solid state switches that took the switching signal from the shutter, or points, and used a solid state switch to collapse the field on the coil. Can the resistanc...

Re: Carlo Durante passed on last night.

Sad news. I too will miss him.

Here's a video I shot when we purchased his old GTE.

Re: Ignition system

Tom, I have their original Magnet Marelli coils. Are they something that can be serviced/rebuilt? Leaning towards using the Rajah terminal connector. I have heard mixed opinions on solder type vs non-solder using the solid core wires. Any opinions from the forum? Clint You can test them with an ohm...

Re: Ignition system

Tom: I would be careful regarding the spark plug connectors. Certainly, by about #6500, 330's used the Bosch style Bakelite connectors. I agree early 330's used black rubber boots, but the Bakelite connectors definitely appear later on the cars. Hi Dyke, You're right. I have my head around 250s the...

Re: 330 SII fuel tank

Get the large 6 ton jack stands and get the back of the car as high as you can. It may also be at the limit of height of your jack, but it's possible to do because I do it all the time. Don't forget to disconnect the fuel tank sender at the top of the tank. There is an access panel below the rear wi...

Re: Ignition system

There are a bunch of directions you can go with the ignition system. Are the coils missing on this car? Any solid core black 7mm ignition wire will work. You will also need grommets to insulate them at the spark plug tubes. The ceramic resistors are commonly used but actually not concours correct. O...

Re: 250 engine water pressure test cylinder heads

Hi Christopher, I use a torque setting at about 55lb/ft. We have gone as high at 60ft/lbs, but it's pushing the limits of the head studs pulling out of the aluminum block. Although a coating on Murray's head gaskets are supposedly not needed, I still use some kind of gasket dressing. I use a spray o...
