Is this good to use on the oil pressure sender , its the thing that screws into the side of the block...

THe other thing is the boltlike fitting on the oilpan that has a wire coming off

would teflon tape work fine for threading these or would it be bad to use ? i want to be sure before i put it on

Won't hurt... just be careful, I'd say don't use any on the last few threads (since there aren't many there to work with)

I didn't use anything with mine... is yours leaking or something?

i was told if i dont use any sealant on the threads that it will leak...

im kind of skeptical about alot of things so i figured i might as well be safe and put it on, although now im doing double the work now because i messed up according to what others say

The bolt, with a wire on the pan is the sub-zero start assist. You don't need it.

I will venture a guess that the OP and temp senders use the block as a ground. (Since they are single wire sensors) I don't usually put anything on the threads for that reason.

are you sure thats what it is ? why would it be on the oilpan ? the wire is a green and black wire, the bolt size is 18mm from what i remember, its the one closest to the front of the engine

... Dunno what floppy is laughing at... as far as I can tell by the descriptions you guys used that quote is right.

There should only be two things coming out the bottom of the oil pan (or 1 thing if you have a series 5) the oil lever sender unit... which is fairly big and held in by 3 bolts.... and the sub zero start assist sensor. It senses if the oil is cold and tells the ecu to use the start assist... which is commonly called useless on these forums.

To clear up any confusion here. You don't need the sub-zero start, you do need the hole plugged. Whether it be with the sensor or a bolt.

The other sensor is the oil level sensor and it has 3 10mm head bolts holding it in.

if i keep my thermowax on the throttlebody assembly buti remove my coldstart resevoir will i need to take this out or keep it on ?

Does takin it off trigger the ecu into limp mode or will i be fine ? My car is s4 na

edit - the oil pressure sender (under the oil filter) is this grounded to the engine too ? or should i be ok putting the teflon tape on there ? because thats what im about to do

if i put the teflon tape on the bolt for the cold start will that prevent it from working ? i may just not connect it anyways... i was just ttold if i dont use anything to seal it that it will leak, is this true ?

Bob_The_Normal

My personal guess is that it is grounded. It only has one wire leading to it and it's a sensor... not sure how you'd get a sensor reading off that wire unless it was grounding to something (block).

You can still put teflon on it though... just do like the second half of the threads, not near the opening end, when you screw it in, it will be grounded by the first few threads, then the teflon will seal the second half from any leaking.

i just prett much put it on almost all the threads but i think it should be ok since the teflon will be cut by the threads when threaded in, this part has given me a headache as ive taken it off and put it back on over 5 times today

edit - im more worried now that there may be some teflon that got stuck in there i donno, but i hope it doesnt do anything to the engine if there is some flying around in there ... this is why i hate doing a job more than once when i was probably fine the first time to begin with

this is because people tell me oh its on there too tight it should be snug, then another person was like yeah u gotta wrench it on there ... then i took it off like 3-5 x in the process, and a few of the last threads peeled off from overtightening (farthest to outside of block)

i just hope everything will be ok even if this teflon is flying around inside it may not be much but it really worries me, i put over 60 hours or more than that into my car , not to mention 3000 dollars i dont want it to be messed up from this teflon or anything stupid like that ill be very pissed
