trust me... when i put the oil filter, i always put oil around the o ringon the top of the filter. i somehow think maybe the oil pressure sending unit is either loose, comming loose, or broken. im going to replace it, clean up the bottom end from all that oil and see if that works any. i dont think it's the guage though because it doenst boune around or act retarded at any time other than WOT.

when you're down here give me a call man... i should have the iroc tuned by then... she's running hard

 

so the oil pressure sending unit looks like an over sized O2 sensor right above the oil filter, right? any special way to take it off, or is it fairly simple? i can remember my d!ckhead friend trying to take it off cuz he thought that was the O2 sensor.. but that was about a year ago when i was replacing it. hmm... now that i think about it, ever since he tried taking it off, thats when i started to notice my oil filter coated with a thin layer of oil. when i went under the car to replace the tranny mount the other day i noticed that the cover that sits between the engine and the tranny was soaked in oil and atf (atf because my old mechanic put too much atf and everytime i run it on the streets, atf comes out of the dipstick, onto the valve covers and down onto the headers and the cover). thanks for all the help guys

 

ATF coming out the dipstick tube generally means the vent tube is clogged up. It's a small tube about 3-4" long right on the top of the tranny case.

The oil pressure sender is the black can with the metal base and the 3-wire connector. Unhook the connector and it just screws out. Screw the new one in, don't use thread tape, and you'll be good to go.

 

thank you sir

anyway, yeah... i was thinking there was too much tranny fluid in there because, first off, the tranny wasn't shifting correctly when i manually shifted the car. it would slip a little when shifting into gear, i'd have to let off the gas for it to shift right, even though it shifted perfect when i was at WOT in D[3], so i put in a bottle of that lucas transmission crap to see if it would help any, and ever since then, when i run it hard, the tranny fluid comes out the dipstick... im installing a transgo kit in my car, so maybe that'll help everything (and im sure the right ammount of tranny fluid will, too)

 

Thanks,
Thats wat I meant but you know how it comes out when ur tired. Good luck Corporate T.

 

i was looking by the oil pressure sending unit and it's pretty tight on there.. but thats where it seems to me that the oil is leaking out because it's covered in old oil and with some new oil too. thing is that i noticed on the driver side on the block where the head meets the back of the block, it looks like an oil stain but it isnt new... it's not there on the pass side though. i dont know if this has anything to do with my problem, but i was going to ask, if i replace my sending unit with a new one, and i still have the same problem, then is it deffinately the pick up, or could it be something else? thats where the oil seems to be... and like i said, it's got some new oil on it too so it cant be when i spilled oil all over the valve cover about a year or so ago. could it be the rear main seals? thanks for the help

 

Rear main will usually drip out the bottom of the torque converter cover. The stain on the back of the heads is likely a leaky intake end seal....SBC's are known for that.

If there's fresh oil around the sending unit change it. They're prone to blowing the diaphragm and leaking through the middle of the sensor. Unhook it, and if there's oil in the connector it's definitely shot. Don't use a GP Sorensen unit....they're total junk and will go out within a year. Get BW if you can.

 

lol i just installed a GP sensor and it's giving me even worse readings than before! ill go back and change it... hopefully that'll solve the problem. if not... ill get a guage. and if that doesnt work, i dunno wtf is going on. and btw... i didnt find any oil on the sender, just around it. weird...

also... i was thinking maybe there was coolant in the oil by a possible leak in the intake gasket... how would i tell if the coolant mixed in with the oil?

 

Ur oil will look milky if it mixed in or u will be able to the see it in the oil. You will be able to tell, it wont look like normal oil should.

 

why would the new sensor be giving me even worse readings? now it doesnt even go up to 50.. it's always chilling at 40-30, and when i step on it, it drops to 15. wtf? lol

 

i just changed the oil and about 2 quarts came out while i let it drain for an hour. the dipstick read normal and only 2 quarts came out? anyway... i filled her up with 5 qts of mobil 1 10-30w (1qt in the filter, 4 in the engine). now the guage reads past 60... WAY past 60, and doesnt move. any ideas? this is a new sensor too lol

 

Either your oil pump bypass spring is jammed shut, or your not getting a good ground at the oil sender. Or you got a new-BAD sender, it happens.
Pegging the needle proves a loss of grounding in the circuit or faulty sender..

 

yeah i have a bad sender... im going to replace it.

i gotta figure out where that oil is comming from! i cant figure it out... i ran my finger behind the china wall where the intake meets the block, and there's no oil. under the area where the heads stick out from the block, no oil. but the oil filter is covered with oil and so is the part that holds the oil filter and the sender. where could this oil be leaking from? because i know when i put my engine back together 800 miles ago i put 5 qts, and now there was only 2. i dont think ive spun a bearing because the car never overheats and it doesnt make any weird noises or anything. im stumped

 

Still up for that autometer eh?

 

im up for it, but only until i figure out why the oil went from 5 qts to 2. maybe that has something to do about the crappy oil pressure. i figured out i snapped off one of the leads on the sender and thats why it wasn't giving me a reading... a soder gun and some 'afro engineering' and i've got it working... but i think the new sensor's shot because it doesnt go past 40 now, even on wot... and before when i changed it, it did... it would go up to 50 and then do what the old sender did and drop to 20 or so on WOT. now i dont think it helped any that when i tried to change the oil, i couldnt get the filter out without having to beat the crap out of it and then drill three holes into that black fitting that goes on it to get it off with a rachet, put nails through it into the filter and struggle to get it off. that **** was ON. but if the filter was leaking, why is there oil on top of it near where the sender is... but there's no oil on the sender? this sucks asssssss
