I have a 79 with a 3.2.
I just replaced my leaking 79 oil tank with a used 3.2 tank sourced from another pelican.
The OEL gauge went immediately up to max.
I checked the oil level and it was good.
took it for a spin and it dropped a little bit from the top but was still close it Maximum, I got the temp up to about 170 ish.
The sensor worked fine 2 days ago with the previous tank.
Any chance it's just sticking a bit ?
Is there any impact or is it just for the gauge?
At least it's not leaking anymore.
Open for suggestions..
