Oil pressure gauge repair, diagnostic steps and testing

[@bradsrestorations1085]

Thank you! I had no idea how to check those. I have learned so much from your videos. Thank you for taking the time to share them. The car is beautiful and you are very close to being finished.

[@VinylVillageGarage]

This test is like 95% accurate there is still a chance it has other issues but normally this will get you there most of the time. Not to mention it’s free and not just throwing parts at it

[@JK_Nex_Garage]

You sure do take the guess work out of troubleshooting those gauges. Excellent video. 👍

[@VinylVillageGarage]

Keep it simple is how I like to do it.

[@coryhage8516]

great info. makes it easy for a one man project to figure out where I'm at.

[@VinylVillageGarage]

Welcome! Glad it will help.

[@billmiller5075]

That car is beautiful

[@VinylVillageGarage]

Thanks and it should be done by the end of this month

[@GoGoGarage]

Glad you figured it out, this will be helpful to many.

[@VinylVillageGarage]

I thinks so too and it applies to just about any GM vehicle from that time.

[@drewpackard6646]

Great video John!!👍🏽

[@VinylVillageGarage]

Thank you. Hope it’s helpful

[@billiebrew2185]

Another great video Jon! Happy Labor Day gang , have a great weekend!

[@VinylVillageGarage]

Thanks. Went to PA to play cars

[@NorthCoast.Garage]

Thanks for this it helped me alot. I have a 76 T/A with the 400 Pontiac and right before I put the car away for the winter last year my gauge pegged way past the maximum pressure line so now I can test it and hopefully replace just the sending unit.

[@VinylVillageGarage]

Right on! The gauge rarely fails typically sending unit, ground fault or damaged wiring being the issue.

[@allsoburnedout3850]

Fantastic job on it!!!

[@VinylVillageGarage]

Thank you

[@allsoburnedout3850]

You're welcome!

[@twobeards6714]

Pumpkins looking great. The owners gonna have a great Halloween 🎃🎃🎃🎃👍👍 I was MIA for a bit but got back in action in time for a 96 degree day. The vinyl top is beautiful. Stay cool😎

[@VinylVillageGarage]

Glad you are back! 96 is hot to me it’s tuff to stay cool. Lol

[@RhinosRestomods]

Thanks for sharing! 👍

Excellent video, might get below 100 this weekend in Phoenix... Might work on my Firebird... Maybe lol

[@VinylVillageGarage]

I need Firebird Friday!!!

Welcome

This is awesome content.

[@VinylVillageGarage]

Very cool. Glad it was helpful

[@firstgenerationgarage2803]

Great video buddy, now hurry up and get over here. I need my temperature, sending unit fixed on my 69 Firebird rally gages waiting on you.

[@VinylVillageGarage]

On my way!

[@Anthony-nw5zv]

Years ago I had a revelation and realized halfway on the factory gauge on a GM MEANT 0 ZERO OIL PRESSURE! I WAS A KID AND GREW UP REAL QUICK.😅. I had bought a 67 Camaro with a 350 4 speed, and the guy told me he raced it on the weekends 😂. I found out the reason it was for sale for $1000 he snapped the oil pump drive shaft on his last race 😯😔.

[@VinylVillageGarage]

Oh man, $1,000 for a Camaro that needs an engine doesn’t sound like a bad deal to me

[@Anthony-nw5zv]

@@VinylVillageGarage well there's more to the story than just the engine. Zero interior, it looked like the first race in the movie Days of Thunder lol 🤣

[@rickstid-bits]

This the first time I've seen one of your videos. Very well done! I've owned and driven my 68 Firebird convertible for the past 46 years, and I'm the only one that works on it. I knew my fuel sending unit was bad but you showed me a very simple way to verify that before I drop the tank. Thank you! Question for you: I have the factory Rally Gauges. All the gauges have always worked well. Then, the oil pressure gauge pegged to max pressure, and stays there. It even stays there with the battery disconnected. I just grounded that wire and no change. Can you tell me how to troubleshoot the gauge? Thank you. Rick

[@VinylVillageGarage]

Good chance the gauge itself is bad or the printed circuit. Start on the back side of the cluster or maybe start at the wire to sending unit you should have voltage with a volt meter when the key is on. If not, work it back unit you find it. Because if there is no voltage to “find” ground the gauge will be pegged high. If voltage is present and all the other gauges work fine it comes down to circuit board or gauge.

[@rickstid-bits]

That's what I was thinking. If the gauge itself is bad - where can a get a replacement? I'm only seeing entire gauge clusters for sale. Thanks for your help. Rick

[@rickstid-bits]

Ps. My car came with the basic cluster and I converted it to the Rally cluster 35 years ago - by figuring out how to do it myself. I only say that so you know I am very familiar with the pod, PCB, and wiring. Thanks again.

[@VinylVillageGarage]

@@rickstid-bits at one time the dealer sold each individual gauge but not sure if you will have any luck finding one of those now. Might be worth looking into.

[@rickstid-bits]

Thank you.

[@RobertPuls-f7j]

I was wondering if you would build and ship one of your body dollies? If it were designed so it bolted together instead of weld it probably could be shipped flat and assembled once received? I would be willing to pay for one. Thoughts?

[@VinylVillageGarage]

Shipping would be expensive. I tried shipping the frame rail jig when I still had it and it was estimated at over $1,000 to ship from Indy to Maryland

[@corvetteguy2629]

My 87 Nissan Pathfinder has 2 wires on it replaced it still no movement on factory gage.

[@VinylVillageGarage]

2 wires on the sending unit?

[@corvetteguy2629]

@VinylVillageGarage 2 wires go into the sending unit Google 1987 nissan pathfinder oil sending unit picture

[@corvetteguy2629]

Fixed the ground wire on the motor to the frame gadge works now ...

[@VinylVillageGarage]

@@corvetteguy2629 nice job

[@jct300m]

How about your Amp gauge?? Is it suppose to move upon start?

[@VinylVillageGarage]

I have not hooked it up yet. I will have to add wires to make it work and will be doing that soon

[@jct300m]

Hope you do video on that gauge..Thanks..Love the videos!!@@VinylVillageGarage

[@VinylVillageGarage]

@@jct300m it is on the list to do.

[@ocexpress]

My gauge conversion has been a pain! New gauge conversion from Ames performance on my 69 Firebird. Temperature gauge good but oil pressure gauge floats to 80 when key off. Key on goes to zero. Start car goes to 80? Any ideas?

[@VinylVillageGarage]

Can’t say I have seen that before, seems To work normal when running. 80 Is a bit high but it’s moving when started. Is it just gravity or an electrical issue. I would try as disconnect the battery as soon as you shut it off, That way you can eliminate it Being an electrical issue.

[@woodrowdelozier1]

[@joeldoepker8898]

Nice car! My temp gauge reads full. With wire attached, wire grounded, wire not attached. Help!

[@VinylVillageGarage]

Temp gauges are a little different lower resistance read hot and higher reads cold. I would start at the sending unit wire unplug it with key on and test for voltage should have just about battery voltage at the wire. If not it’s shorted to ground someplace. If you do have voltage might be a faulty gauge

[@burntclutches]

You mean a 50yr old car gauge and sending unit didn't work perfectly first try lol?

[@VinylVillageGarage]

I know this is totally unacceptable 🤷‍♂️

[@davidbisnette7673]

That is such good information, great video!

[@davidbisnette7673]

That car is looking marvelous
