Oil Pressure Sender Removal - C4 Corvette

[@jackmanfredo1215]

All your videos are definitely showing me where things are located and how to access them on my 84 Thanks Mike!

[@Mikes84Corvette]

Thanks for watching!

Great video, nice job. Tight space thats for sure.

[@Mikes84Corvette]

Thanks. Yep tight space but once you remove the wiper motor it’s not bad.

[@anthony84vette]

There is a check valve right alongside that oil pressure sending unit that's vacuum for your cruise control and the EVAP....also one end of the vacuum goes through the firewall for your HVAC...............right under that brake booster you should have a t to plug that into.....

[@Mikes84Corvette]

Thanks for the info! I will take a look.

I believe I’m having a problem with mine. You said you were going to post if the pressure came down from 80. That’s where mine is now. Sometimes it does come down but it jumps around and goes back to 80.

[@Mikes84Corvette]

Mines still at 80. I bought another one to see if the first one is bad. I have yet to install it.

[@lancebrantlinger-tommy3558]

@@Mikes84Corvette Yeah, it’s very odd. Every so often, I’ll be driving and it will drop to 55-60 and keep flip flopping around then go back to 80. I have a new one to install but after watching your video, makes me wonder. Let me know what happens if you would.

[@Mikes84Corvette]

@@lancebrantlinger-tommy3558 I've been doing some reading about this and everything points to either a bad sender or the connection to the sender is bad or not fully seated. One test is to unplug the sender connection and see what the oil pressure reading is. I'm going to try that. I should make another video too.

[@lancebrantlinger-tommy3558]

@@Mikes84Corvette That would be great! At least this is something that doesn’t effect the drivability of the car.

Hello, I just got an 84 corvette as well. Need some work as well. Any pointers as far as engine work ? I’m in NJ as well.

I’ve brought my corvette here: www.bobcrevauxsauto.com

[@KonradG-o7c]

is it really necessary to remove the wiper motor? I am struggling to remove the electric plug on top of the wiper motor, it wont come out, possibly the connectors rusted on ? i dont want to force it and break something....

[@Mikes84Corvette]

I suppose if you can’t get that plug out you might be able to at least move the motor out of the way somewhat. Makes the job easier

[@DjNeoTeC]

What was your pressure before you replaced it ?

[@Mikes84Corvette]

It was good. Never below 30 at idle.

[@DjNeoTeC]

Ok nice thx I have pressure problems while hot idle

[@Mikes84Corvette]

@@DjNeoTeC what pressure are you seeing?

[@DjNeoTeC]

when hot up to 50 while idle its drops when its hot to 12 some times its showing 0 but there is no noises from the lifters or anything. m8be i will check the sensor ... @@Mikes84Corvette

[@Mikes84Corvette]

@@DjNeoTeC According to the manual - "out of normal range" is below 25 psi over 4000 rpm and below 4 psi under 800 rpm.

[@CallforthePriest]

Great video as always Mike! Hey i was curious, are your heater hoses stock or have you changed them? Just on my list of things to do, so i was wondering. Thanks!

[@Mikes84Corvette]

Thanks! I believe they are original.
