i was going to install a firewall relocation kit but decided to put the stock sensor back in. started the car and it leaks from the oil pressure sensor hole.. it is a B18B in a 93 civic.. what can i do??? PLEASE HELP!!!

 

Did you thread it in correctly? Crossthreaded? Use any teflon tape when you reinstalled it (not sure if you're supposed to or not, I did).?

 

you can try using some teflon tape or thread sealer.

 

it threaded in fine and i did use a little teflon tape.. maybe ill take it out and try more tape?

 

ok i have a feeling im prety fucked because the leak looks like its coming from an area on the block to the side of the oil pressure sensor ? it doesnt look like its coming from the threads ? is this a possibility? if so ehat couldve happened and what can i do ?

and to top it all off its getting dark

 

ok it looks like there is a small crack.. what can i do? im going to try to take a pic

 

You're supposed to use Hondabond, not Teflon Tape, on the oil pressure sending unit and sensor.

As for your crack, well, that's unfortunate. Take pictures and maybe we can help you.

 

ok theres no way i can get a picture so im going to try to explain it in detail... the area on the back of the block is "raised" where the oil pressure sensor screws in.. there is a smallll crack on the raised part.. does anyone know anything i can put on it to seal it ? ANY ideas ?

 

JB Weld?

So you split the block, damaging the oil passage. That sucks hardcore. You might be able to get it welded, but if you did enough damage in that area, you might have to get a whole new block.

Be more careful next time.

 

hey i just threw some JB weld on it i guess ill let everyone know what happens.. its a VERY TINY crack.. well see

 

did the block split cause you overtightened the sensor or becuase of how u were dirving or something?

 

im guessing i over tightened it

 

leaked slowed but its still there.. cleaned it up and threw some more JB weld on it.. theres no way im gonna be able to trust it long distances, etc. you know what i mean? any ideas? i called a local shop and they seemed to know what i was talking about right away so im guessing it happens.. but in order for them to weld it they would have to take off the intake manifold, etc. to get to it which would lead to some crazy labor.. is there anything else i can do ? and has anyone ever had theirs welded? and if so how much were you charged? or if anyone would like to throw some prices at me let me know

 

if it were me i would swap out the block. im all about keeping stuff reliable. i dont know how reliable welding the block is but i know putting one thats not cracked in there is good but if you have to pay someone to do the swap then that could be expensive. what it comes down to is that if you cant fix/do it yourself, its gonna cost you some cash

 

find a local guy that can weld aluminum. take off the intake matifold and have him weld that crack shut.

 

ok JB weld didnt work.. if anything its worse lol.. has anyone ever used "alumaloy" ? i see they can even repair engine mounts with it. Does anyone know anything about this stuff ??

 

 

anyone know how to get JB weld off easy ?

just have it welded. anyone who is half decent at welding can safely weld aluminum.
