Oil sending unit is leaking
ok so my oil sending unit is a black cylinder about 3 in long, screws right into the front of my block. on the back of it there's an electrical plug. Well its leaking around that plug. inside the socket. i cleaned the oil off, and when i unplugged it, oil dumped out.
Its not leaking around the threads but up top, at the plug. and I'm 100% on that, very obvious, its almost a steady stream. Ive got an oil sending unit ordered. anything i need to know before i swap it out?

Not really. The replacement should come with teflon sealant on the threads. Just BE CAREFUL when putting the new one in. You don't wanna break the new sender while installing it.

Not sure of the exact style of yours -- but you may need a special socket. Removing the old one isn't the problem, just don't bugger the new one up with the wrong tool.

You have to have a special socket. Get it at the zone

I just replaced the one on the GF's car a couple weeks ago and all I used was a simple cresent wrench to get the job done.

Ok well the crescent wrench sucks...the platic part of the OSU fell off first time i touched it, so its just the brass piece...its mostly round, but has like 8 flat spots. but they arent big enough for the wrench to get ahold of...so now im fucked till i can borrow better tools

get the opsu socket to make it a quick job, that white tape stuff for pipe threads will ensure it doesn't leak when you put it in.

ok cool, may look into that that
it looks like it has thread lock on it already, im not gonna worry about teflon unless it starts leaking.

I managed to get it done pretty easy with a pair of channel locks.
My car also runs better now, nothing special, but its noticeable. does the OSU communicate with the computer i any way.
the only thing i've really noticed is that after my intake gaskets got replaced a few months ago, my car kinda surged between 1500 and 2k RPMs. like, if im cruising along at 1500, then try to accelerate, but not hard enough to downshift. it just felt like the tranny was bein bitchy and didnt wanna drop back to third. did think much of it.
anyway, as soon as i swapped this thing out, that stopped.
