Well you want as much of the transmission oil to be in action in the system so the level can be checked. When the engine is running the front impeller is spinning and pumping oil around. When you are in drive the oil goes through some other areas of the transmission but I would think the...

How many old fuel tanks will be examined now.

The little hole is called a bubbler. It lets a small amount of coolant through. Helps avoid air pockets. Do you think the old one might have a larger opening and more flow through the body?

Humm.... those knobs look closer to what's on the trucks now. Thanks! Those guys are just down the road from me.

Yes that product link looks like it is the same as Lab Metal. I saw the quote - I believe it. This is tough stuff. I remember now when I put thin layers on my knuckle housing. Each time it cured out, to smooth it down I had to use a metal file first and then many sheets of cut sand...

You might be able to get the larger areas to shrink some by heating the metal and using a hammer and a wooden dolly or by putting a wet cold quenching rag on the metal to shrink it. Google that and you find bunches of info. I would try that first before doing bondo on those areas. There is...

If the surface is clean metal and not huge holes bondo will stick for years. It does not repel water so it needs to be primed and painted, or you will get rust under it and then it will pop off. You want a thin coat of bondo. If you are laying more than 3 mil or 1/4 of an inch you should be...

Lab Metal is great stuff. The curved curved part of my M38A1 axle housing the knuckle seal rides on was rust pitted. I used it to fill those holes and it is still on there. It is tough stuff and hard to sand. Bondo would be easier and faster. Cheaper too.

Do you have a part number? I need one. lol

There should be a one way vent on the axle. That might be what you heard. Sometimes the vents can clog causing too much pressure in the axle. Then the axle oil can migrate to the bearings. But if yours are open that's good.

Yes please give us a list of goodies!

That rim looks like a M35 or M211 rim.

I like the idea of flushing it. How would you make sure the flush fluid was all out? Or it needs to be compatible with the normal oil.

That's a bummer. It would have been easier to fix taking it off. Nice looking muffler. :mrgreen:

That is good news!

They are Suntune models, I got them back in the 80's. I took a quick look online and can find inductive timing lights but not tach/dwell meters. (Maybe a used one could be found?) But I did find and attachment for a Fluke electrical meter to allow it to measure dwell - Fluke RPM80...

I have an inductive tach/dwell meter. I connect the power to one of the batteries and the sensor to the plug wire adapter I have. My timing light works the same way.

Not sure if one psi would cause that. Maybe if the valve spring was weak? I went and bought some brake line that fit the carb inlet, cut it off and ran a rubber fuel line with a filter to my gas can to test my rebuild. I just left the original line hanging there but disconnected the power to...

On my truck for testing I ran a line from a small gas can to the carb. There should not be much pressure from a gravity feed situation. That way you might could test the theory the pressure was forcing open the valve.
