Sorry Joep, I noticed a question here. Missed that one at first.
Well, I think any serious tar making would separate. Only a small amount of tary fumes may stick to the soot and not be enough to be noticed, but if your pot is still clean after washing it with only water you’re ok.

Thanks JO, no problem, I am not in a hurry here😀.
There was a little debris at the bottom. Tar is heavier or lighter? Next change is that separator someone posted. Not a cyclone but kind of. It will take most of the pieces out. To be continued in its own topic. Thanks JO.

Almost all the tar will sink to the bottom. Only some lighter oily fractions will stay on the surface and shine in different colours like a squirt of gasoline in a puddle of water.

For the past week or so I’ve been using the Mazda truck for all my driving. Reason - a hot leak in the Volvo gasifier. It still runs ok, but temps are climbing super fast. Rail temps that I’ve only seen a couple times running full speed on longer trips, I suddenly hit right after lightup in just a few hundred yards. This leads me to believe the leak is in the heatexchanger - close to the guage.
Yesterday I taped my phone on a stick and stuck it into the gasifier cleanout door. I plugged the nozzles and with a tight fitting I blew compressed air into the air inlet. I expected to see a cloud of dust - but nothing.
After sleeping on it I tried a different approach today. I lit a cigarette at the air inlet, cranked the engine up on gasoline and let it breathe through the gasifier. Smoke didn’t appear where I suspected it to. I still think at 10 o’clock in the heatex, air have burned the soot off of the fins close by. At 2.30 smoke does appear, but that’s from the nozzles. They weren’t plugged this time. They should have been.

Where did you get the cigarette from? Did you buy a pack of smokes just for testing the gasifier for leaks or did you start smoking in the last few days, I sure wish there was another way to make smoke… 
It looks like on the heat exchanger inlet between ten o’clock and twelve that there is a crack but it is probably only a bit of a sootcake that fell off.

Haha! No, no smoking. That was just old butts from visitors I found in a jar on the porch 
Yes, brobably a flake. But still, in that area the soot seems to have been burned off - air present

I would mix up some liquid soap and water with a spray bottle, and blow air through the inlet. Spray on any suspected welds.

Most people here brag about how cheap they are. But noone is a match to JO. He even saves and uses up old cigarette butts step away, amateurs

So look back on your build of your gasifier, you will be needing to do some cutting into the gasifier metals to get to it to fix it right.

Hi Cody. Unfortunately none of them are on the outer skin - all internal.

That’s true, Bob. It will require some major surgery. You know all about cutting into used sooty parts. I wonder if this one will have to wait until spring, so I can work outdoors.
Well, we’ll see - I can start snaking the gasifier outof the trunk and one thing will lead to another. I’m not in a hurry. I still have the Mazda truck for DOWing.

When I was troubleshooting my gasifier seems like I ran across a recipe for a smoke bomb that used tin foil and ping pong balls.iirc you had to cut the balls into pieces.

That’s interesting, Tom. I can imagine the plastic balls smoke as they melt, but I don’t understand the purpose of the tin foil? Or was it used just as a pot?

If I remember correctly it was just used as a pot or container. I just googled it and there are various ways to make a smoke bomb with pp balls but don’t remember the one I used

The balls used to be made of nitro cellulose, similar to smokeless gunpowder (ironicly). Unfortunaly, they are geting hard to get and any other material will not work. They contain jast enaugh oxigen in the material to be able to smolder without air, hence the aluminium foil. We used to lay the whole ball in a lair of foil but you can also cut it up to get more material in.

I was thinking about your car now that I’m messing with the iller.
Could it be that your hearth is being cooled by incoming air, when you are idling, and then it takes a while for it to warm up?

I don’t know, Jan. The air flow is very low at an idle, but it’s possible.

Just so everyones on the same page, smoke bombs in the US as of last week became federally regulated so uh. Ya dont ask how to make them if your worried about a knock on the door from annoying 3 letter agencys

The NSA captures and feeds everything discussed on phones, typed on forums or social media, pretty much all modes of communication, through their mega computers and mainly looking for key words. B**B is a main one. Better to erase it from your vocabulary. It is not denied. Not conspiracy theory.
