Dumb question but what is this. Found this pic on a thread on here.

 

It is the sending unit for oil pressure I believe.

 

Ok good to know.. Oil pressure been actin up so maybe I will check this out.. Would a cooling problem affect oil pressure?

 

A cooling problem should not have an effect on it

 

An extreme cooling problem might affect oil pressure.

Hot oil=thin oil=possible drop in pressure.

I have noticed this especially with rigs that are due for an oil change.

 

Thanks guys, appreciate the feedback.

 

And dont be afraid to keep asking questions. we all had to start some where.

 

Looks like a oil pressure sending unit, and I bet it is on a small block 289 or 302??? No dumb questions here, if you do not ask most that could happen is it could cost you $$$.

They are a cheap and easy part to replace.

 

Thanks guys, Appreciate the help, mine is covered in oil so at bare minimum I'm gonna clean it up, was just curious what it was.. My #2 cylinder is toast, I think that's part of my oil pressure problem, just saving for my new long block.. It's a daily driver so I just baby it and fix the cheap stuff as I learn more..

 

Covered in oil could mean the o ring on the thread in tip is shot...I think it has one anyway? If leaking around the elec connecting part or any where else, its just replacement time.

Make sure it is not leaking where it threads into the block adapter. Looks like it has thread tape on it too.

 

On a 302, it's NPT threads, no O-ring. Thread tape is always a good idea with NPT fittings.

 

Those that know have spoken, thanks for the knowledge.

 

Always remember if you use thread tape on these or any sending units to not use too much! You will have grounding issues...Don't ask me how I know

 

Yes, very good point!

 

Thanks guys appreciate the help, the one in the pic isn't mine, I just found that pic on here for reference for my question.. I'm gonna clean mine up and check what you said this weekend..
