garyb Posted July 1, 2014 Share Posted July 1, 2014 2 service managers ago manager loaned out our gauge bar with all the diesel gauges on it, now on multiple occasions I come up to time to check crank case pressure and do not have the tool, inform manager and still has not bought one. looking to get my own magnehelic gauge was wandering if any body has any suggestions on one with a reasonable price Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted July 1, 2014 Share Posted July 1, 2014 Are you just looking for a magnehelic or a new gauge bar? Although I don't use anywhere near as often as the past I still find it useful to have the bar. Diagnosing pressure and restriction issues is easy when you can hook up multiple gauges at a time. As a Ford Dealer you really should have the gauge bar. http://www.dwyer-inst.com/Product/Pressure/DifferentialPressure/Gages/Series2000 Quote Link to comment Share on other sites More sharing options...
Bruce Amacker Posted July 1, 2014 Share Posted July 1, 2014 I've never trusted the big Magnehelic gauge. They're probably accurate from the factory, but after being shop handled a couple of times I'd rather use a water manometer. Simple to make and use and never inaccurate.

garyb Posted July 2, 2014 Author Share Posted July 2, 2014 thanks, will look into water manometer , and I agree with keith as a dealer we should have gauge bar, but we do not at this time, and managers are reluctant to replace the one that is known they loaned out and did not receive back, it is on my shoulders to provide accurate diag, and these tools are needed to see the whole picture.

You tell them that you cannot diagnose the truck because you do not have the required test equipment that you are supposed to have. Is it YOUR fault that a previous manager lent out the tool?

forddieseldoctor Posted July 5, 2014 Share Posted July 5, 2014 I don't know if I should say this, but I've never used one. The one at the shop I'm at now musta been washed off with brake clean once cause it's so foggy you can't read it. I've been buying all of my own manual gauges as I need them.

forddieseldoctor Posted July 5, 2014 Share Posted July 5, 2014 And then just draw the needle where I want it to be? Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted July 5, 2014 Share Posted July 5, 2014 Nope, you gotta cut a sweeping arc style slit across the plastic face, then modify the needle to where it has a 90 degree tit that pokes up through the slit and then your golden! 1 Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted July 6, 2014 Share Posted July 6, 2014 oh man I crack myself up. However it is quite possible that you would find such shenanigans at my current dealer. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted July 6, 2014 Share Posted July 6, 2014 The manometer is not a gauge you would need very often however it is crucial to diagnosing cylinder sealing concerns... damaged cylinders or an engine that is just plain old worn out or dusted. Excessive crankcase pressure no matter what the reason means major engine repairs or replacement is necessary. But I suppose I am preaching to the choir here.

garyb Posted July 7, 2014 Author Share Posted July 7, 2014 looked through 198 pages of rotunda catalog and did not find gauge bar, and it seams that if you work on the 6.4l engine that the need to check crank case pressure comes up quite often when dealing with miss fire concerns, easier to check before you check manual compression. truck that I was working on run good down road, had white smoke after sitting and idling, not using coolant, customer did not add coolant, had 6gun banks tuner on it, dpf delete, banks ram air filter, relative compression with ids had cylinder 8 down 5%, power balance test with ids under manual balance screen shows cylinder 2 and 8 down by at least 15, manual compression test showed cylinder 2 at 290 psi, and cylinder 8 at 250 psi removed valve cover and inspect rockers, all looked ok, not broken, would have been nice to see crank case pressure since there was no abnormal noise in engine not popping back through intake and cranking engine with rocker cover off did not reveal any thing abnormal.

Bruce Amacker Posted July 7, 2014 Share Posted July 7, 2014 Gary, did you check STFT and do you remember what it was? Just curious........ Quote Link to comment Share on other sites More sharing options...
garyb Posted July 7, 2014 Author Share Posted July 7, 2014 ya remember that 8 was 19 and 2 was pretty high don't remember exactly but disabled banks tuner and reset fuel tables, test drove and went back to same fuel trims, had all trims wrote down on ro at work, will check in morning.

Aaron Posted July 7, 2014 Share Posted July 7, 2014 Wonder what he was using to turn the REGEN off. Six gun I don't think supports "off road" tuning. Quote Link to comment Share on other sites More sharing options...
Aaron Posted July 7, 2014 Share Posted July 7, 2014 Or that may be why the motor is wasted. Quote Link to comment Share on other sites More sharing options...
garyb Posted July 7, 2014 Author Share Posted July 7, 2014 speed shop that installed tuner told customer that it was just for fuel economy, I thought why do you need 6 different selections if just for fuel economy Quote Link to comment Share on other sites More sharing options...
Brad Clayton Posted July 7, 2014 Share Posted July 7, 2014 We have a metric shit ton of 7.3's running around down here, and the crankcase pressure gets checked on everyone that's in for a drive-ability issue or starting problems and what-not. The average miles on diesels that come to the shop is over 200K. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted July 7, 2014 Share Posted July 7, 2014 014-00761 Does not appear anywhere in the Rotunda website. I guess it is not important anymore. ...there are some listed on EBAY ...you could always make up your own. Quote Link to comment Share on other sites More sharing options...

The average miles on diesels that come to the shop is over 200K. I'm not saying it's not. However most people around here wouldn't care if I told them they had a motor with slightly excessive blow-by. If it runs and gets them from point A to point B they are more than happy with it. I should make a manual one and do the crankcase pressure test on my old 7.3 but I don't know if I really wanna know how bad it is. Quote Link to comment Share on other sites More sharing options...
forddieseldoctor Posted July 8, 2014 Share Posted July 8, 2014 The gauge on the bar is a Dwyer series 2000 part number 2060. I found it for $70 shipped from an hvac tool site. Unfortunately the picture is a generic one that shows the wrong scale on the gauge. http://www.hvactool.com/products/dwyer-0-60-h2o-magnehelic-differential-pr-gauge-dwyer-2060 Quote Link to comment Share on other sites More sharing options...

batmantech Posted July 14, 2014 Share Posted July 14, 2014 I was at a mall a few years back and there was a small art show. This guy had made a small art motorcycle you know the ones with wire and other random reused parts. Well there it was a magnehelic guage acting as a gas tank. I talked to the artist and he had no idea what it was until I told him. Quote Link to comment Share on other sites More sharing options...
