thanks rich, you're a badass you know that :) one tip on mixing epoxy/JB. put both components into one corner of a plastic bag and massage it. once it's ready just cut the end of the bag with scissors and use it like pastry bag for decorating cakes. no mess and really easy.

I just read this on "Ford-Trucks Forum" where a forum member was building the same and referring to this video. I also saw the same done from my Google Search......"So, we could get around the lack of repeatability by using a Holley main jet of .040" diameter for the orifice. They are cheap and easily acquired, but would make the process of building the tester a bit harder since you'd have to drill the JB Weld with a 7/32" bit and then tap it with a 1/4-32 tap to take the threads of the jet."

Right to the point. Thanks Rich

@chrispompano 11 лет назад

Thanks Rich, I very much enjoyed the video to forward to another Caddy owner who is in need of one.

@MrZayne8 9 лет назад

Interesting work there Richpin. I enjoy do-it-yourself projects like this. I will give your idea a shot.

@jamesbrody5072 10 лет назад

Thanks New York or New Jersey. Just made one with some stuff I had in the garage. Awesome tool for pin pointing problems inside the motor.

@carlosquinto5937 10 лет назад

Thank you Rich. Great tutorial. Now I can avoid spending too much on a tester.

@BiteDoctor 13 лет назад

Your howto video is hands down one of the best no bullshit, high quality videos ive seen. so many useless vids on youtube, that say "how to ___" but its crrrap. Thank you richpin06a

@rick62008 13 лет назад

@chrispompano 11 лет назад

Here's what the "evolutionm forum" stated: "Anyone who knows anything about the FAA (Federal Aviation Administration) knows FAA doesn't screw around when it comes to engine maintenance standards. FAA established the standard for leakdown testing, and requires a 1mm (.040") orifice be placed between the two gauges. In other words, when pressure is applied (e.g. 100psi), what we are looking for is leakage in the cylinder as compared to the airflow through a 1mm orifice at that pressure."

@RichpinTv 13 лет назад

@seasonedtoker I will try that...thank you

@RichpinTv 12 лет назад

@Robonza I think the plug was in the 1/4 to 1/2 range.

@RichpinTv 11 лет назад

Wow so cool they were referring to my video.

@omarG19100 11 лет назад

nicely done rich =D

@chrispompano 11 лет назад

SPOT ON! Yes, I did a Google Search: "How To Build A Leak Down Tester" and the 1st 3 links were very good info. that also show different versions of building testers.

@RichpinTv 11 лет назад

Yes you can put the valve back in the hose when your done.

@RichpinTv 11 лет назад

I read an article on building the leak down tester which had the drill size in it.

@Surannhealz 13 лет назад

good diy vid!

@gst69man 13 лет назад

cool vid, thanks

@RichpinTv 11 лет назад

Yes i believe you can. Important Update: Jan 1 2013 there will be a new richpin channel for all future videos.Richpin06a channel will be solely for all the Saturn lovers out there.Should be a lot of fun so stay tuned.

@mishaparem The drill is a #60

@yveslegrand9826 Год назад

Hello, thank for this helpful video. I was wondering what thickness the epoxy "jet" should be ? Does it change the instrument sensitivity ?

@evemizerrago7287 4 года назад

Thank u sir

@RichpinTv 13 лет назад

@ad6a8a If you leave the valve in that hose the air from the tester will not be able to pass through the hose.

@TheSlycooper111 8 лет назад

what kind of stuff you put in the 2" pipe to make restriction ??? is it like iproxy or sommeting like that

@santoshritpure7924 8 лет назад

Relay nice 1

@ad6a8a 13 лет назад

Hi Rich, Great video. At 1:30 you say "I'll take the valve out of the compression tester hose". Do mind explaining that more. Also, the commercial testers that I have seen have 2 gauges, but I guess only 1 is needed? Thanks, Glenn

@justbuggin67 11 лет назад

Thanks and thanks for showing how to use it on a vw engine. Ill be using it for 2 vw 1200cc motors. Stupid question, you mention using a compression gauge hose but you have to remove the valve stem. Can you reinstall the stem or is will the hose only be used for the leak down tester after you remove it

@justbuggin67 11 лет назад

Seems like you can add a 2nd gauge just before the pipe with jb weld and after the regulator to create the dual gauged leak down tester. Am I correct in this assumption?

@chrispompano 11 лет назад

How did you determine the size of the orifice to drill in the plug in order for the proper calibration? Thanks, Kind Regards, Chris

@RichpinTv 13 лет назад

@cbancaw2010 I might be able to help what would you like to know.

@dtrrtd774 7 лет назад

Doesn't the depth of the JB Weld used for the orifice alter the flow? If it were an orifice drilled into a thin metal plate vs. an inch thick plug, as extreme examples for comparison, wouldn't the amount of leakage change? Maybe it doesn't matter in this application, but I was thinking it would be like comparing air flow through a 2 foot hose vs a 100 foot air hose of the same diameter, where I'd expect the short hose to flow more.

@davidtyndall8880 7 лет назад

If you were flowing into "free air" the length of the orifice would come into play but in a leak down tester you are mostly flowing from one pressure value to a lower one but not to a "zero" pressure. The flow rate would be a great deal less. In other words the length of the orifice should not matter a great deal.

@mishaparem 13 лет назад

hello, awesome video. When you say number 16 drill bit, do you mean 1/16 drill bit?

@tmackinator 9 лет назад

My apologies to richpin for mishearing the size of the drill bit. This is indeed a well done video and a correctly designed tool.

@RichpinTv 13 лет назад

@pikey2530 To much air passes by the gauge and the reading is meaningless.

@angeloyourreflection9331 3 года назад

Richpin06a Today i went to a small hardware store to buy the #60 drill but i dont have a drill to use it but when i do go buy a drill what drill should i buy or something to be able to use the #60 so it wont break since its so small and thin? I need help please im a newbie beginner

@4dirt2racer0 5 лет назад

doncha knoww!! thats a pretty serious northern accent :p

@RichpinTv 12 лет назад

I presumed by using the correct drill that it would be accurate.

@tmackinator 9 лет назад

The size of the restriction orifice has a direct effect on the rate of leak-down . The larger the orifice, the greater the leak down percentage for a given initial pressure. I believe that most leak-down gauges use a .040 diameter restriction orifice to work with a 100psi initial pressure. In your second video where you say you have 60% leak-down, that is not accurate. You have no baseline comparison to make such a statement. Your tester could only be used as a relative comparison between the cylinders on the motor. I doubt your engine has a 60% leak-down unless it is really worn out. You may want to make a slightly more precision orifice of .040 dia and compare your results. I'm not saying this as criticism at all, your vid was good. Only for information.

@d.kendrik1427 9 лет назад

tmackinator......what is your point.., exactly..? Are you implying that richpin06a is incorrect.., by indicating the use of a #60 drill bit..? If so.., perhaps kindly check 'your' information.., as you are incorrect. The ( #60 ) drill bit..., is in fact... a .040 size bit.., and not.., .060.., that you seem to be inferring. Go back to 1:18 and observe.., then do your homework before... "not saying this as criticism at all". As you will see for yourself.., and lectured at length about.., your recommended.., precision orifice.., of .040 dia.., is..., correctly indicated by this gentleman.., with the instruction to use a #60..., aka .040" dia. drill bit. I'm not saying this as criticism at all.., only for information.., correct information.., as provided.., in this well organized and helpful video. Thank-you richpin06a..., Cheers to you Sir.

@tmackinator 9 лет назад

+D. Kendrik Well I'm not one to admit an error on my part. I did not see the beginning of the video . I misunderstood the drill to be 1/16 not a #60. However my information was quite correct about the design of the tool. My comments were not done in a critical manner. I was not trying to be critical. I said his video was good. What should I have said? Take a chill pill!

@RC-Heli835 9 лет назад

Thanks for sharing man. Why doesn't yours have the standard two gauges on it that most have?

@RichpinTv 9 лет назад

ILTSYC It is a little less expensive to make the tester this way.

@RC-Heli835 9 лет назад

Ok I found a regulator for 10 bucks at Orielly's with a gauge. I just have to get a couple of fittings and make the damper or orfice. I believe I have a blown head gasket on my Ford Windstar mini van. I can hear a puffing under the hood and I've been losing water but not getting oil in water or visa versa. I believe its the middle cylinder leaking to the outside of the engine from the head gasket. The engine sets sideways against the fire wall. I can unplug the fuel injector on that cylinder and the RPM doesn't drop at all like it does on the other cylinders. I want to build one of these leak down testers to try and determine if the head gasket is actually blown. I'm afraid it its though. It will be fun doing the leak down test at least, except for finding top dead center on those cylinders against the headwall. There has to be a pain in the ass somewhere in the mix no matter what you do. LOL!

@billphil8235 9 лет назад

What is the purpose of the J.B.weld plug with hole? other than reducing air volume?I have had the same set up minus the plug for years and it works fine

@RichpinTv 9 лет назад

Bill Phil The hole calibrates the air like a jet in a carburetor.

@Dalebrah69 9 лет назад

Calibrate the air for what I plan to make one for my dirt bike. . From Australia Great video I've watched it over and over (y)

@RichpinTv 9 лет назад

Dalebrah69 The leakage in the engine is compared to the flow of this orifice (plug), calibrated air.

@mikewallybanger3457 10 лет назад

Why was a #60/.04" hole chosen for the size of the restriction and how was this determined? I'm assuming it has something to do with the volume of air that could conceivably leak past the rings/valves etc but I'm not sure. Is there a formula to calculate a restriction size for different operating pressures? I imagine a larger hole at 100psi would give you a lower value for the leak percentage so this is relatively important.....

@patw52pb1 5 лет назад

Yes, the 1mm or #60 Drill size 0.040 inch reference metering orifice is to develop a differential pressure that is proportional to flow volume. The 1mm or #60 Drill size 0.040 inch metering orifice is capable of being accurate over a wide range from about 70 to about 125 PSI air pressure on engines with cylinder bore diameters from 2.5 to 5 inches. This is from published data by the FAA. There are several online academic papers that describe the physics, mechanics and math calculations involved.

@Migzc90 10 лет назад

Can u kindly explain whats the point of the lil hole u did with the drill bit?i dont get it

@RichpinTv 10 лет назад

It acts like a jet in a carburetor which is a precise calibrated part for metering.

@serchmarc 10 лет назад

hey rich is necessary the epoxy with that small hole? cause i ve seeing another 1 from a kid on youtube,, with no small hole.

@RichpinTv 10 лет назад

Without the small hole i do not think the tool will work.

@serchmarc 10 лет назад

you said #60 drill bit,,, sorry to ask but what the diameter of that drill bit in inches or mm?

@RichpinTv 10 лет назад

serchmarc I believe it is .040

@serchmarc 10 лет назад

i believe you talking about inches,, ok ill convert that into mm thanks man for your time

@serchmarc 10 лет назад

richpin06a 0.040 40 thousands? what the? i think is 1 mm drill

@TheNDex 7 лет назад

Hey rich, do you know the total cost to make?

@RichpinTv 7 лет назад

I wish i would have kept track of the prices for the parts.

@Sea2Skyward 13 лет назад

you sound like the guy from the yankee workshop

@claudiomassio687 7 лет назад

hello, i am not good speak in English, I hope that you can understand me...my question is how milimeter ....how fat is the mecha to do the agujero, hueco?

@mummyjohn 7 лет назад

#60 which is 0.040 inches

@patw52pb1 5 лет назад

1 mm = 0.040 inch = #60 American Drill size
