My mechanic needs to locate the oil pressure sending unit on my Old 455 GMC. He can't seem to find it. Can anyone give me some info on this?

Sir: the oil pressure warning light switch is on the LF top of engine next to the water neck. It has a wire going to it that will cause the light to go out when unplugged and come on when grounded.

Here is a pic that shows the oil pressure sending unit sitting on a "T" with another feature added. Sorry about confusing it with an idiot light.

You might be best advised to get a new mechanic if he cannot even find an oil pressure switch!

I see that others have told you where it is.

Since I was apparently the only one that criticized the mechanic I assume that this statement was directed at me.

However, I feel that my suggestion to get another mechanic in the long term would be the best advice I could give to really help Ken Burgett.

His mechanic is obviously not familiar with GM engines of the vintage of the GMC motorhome. Ken would be far better served if he finds one who is.
His mechanic is likely charging by the hour and if he is being paid to learn on the job then that could get a bit expensive.

Not really Emery--in fact you weren't the only one and I think you are right. However, there are some folks here (me not included)that always just supply a good answer without any personal opinion attached. I really like that and again, I'm not blessed with that.

Both Rob and Howard supported your opinion, and I believe no one
disagreed. Certainly not me...

Guys, remember this is an older engine and the switch doesnt look like what newer (younger) people are used to seeing and where its located.
It doesnt look like an oil switch that I am used to seeing also and it works differently than we're used to (me)
(humor)
I thought I was wrong once.....

Thankx

I think it was meant as constructive advice. Even if you were a mechanic born after there were no non EFI and non Computer cars being built, the basic senders and switchs on engines are rudimentary. Or if you don't know where it is you should be able to find it through basic trouble shooting ( hands on ) or the internet ( hands off ).
