I need help (oil leak)

sapo · 11-05-09, 03:13 PM

I ATTEMPTED TO CHANGE OUT OIL PRESSURE GAGE & SENDING UNIT & I THINK I GOT THE WRONG ONE & I THINK I OVERTIGHTENED THE SENDING UNIT & NOW THERE IS OIL EVERYWHERE I THINK I PUT A CRACK ON THE BLOCK IS THERE ANY FIXING TO THIS

first you should check the sending unit, and yes you can fix a crack in the block but you will have to have an acetylene torch rig and either you braze it or you use an rosebud to heat the block then weld it. but blocks are pretty tough so check the sending unit first.

well thnks i did check the sending unit i thought that was it so i put the original one back in & still have the leak so i guess im off to find a shop that will fix it. just one more thing that looked like an easy thing turned out expensive

did you use thread sealer on the threads.

i can not see how you could have cracked the block replacing the oil sending unit.

x3. I changed mine when I installed an SR5 instrument panel. As other have said, I can't see anyway that you could crack the block with one of those sending units.

sorry im back i work nights so i get lost from time to time but yes i have a hard time believing it too but i guess if it could happen to anybody it would be me but yes i put teflon tape and a thread sealer and it still is leaking i guess i will take another look just to make sure but i hope i am wrong do u guys think maybe putting like jbweld would work

toy4xfun · 11-11-09, 03:31 PM

you could but i do not think you could get it in the crack. and if you put it on the threads you would not get the sending unit back out to easily i would say don't do it.

Clean and scrub the block good, then fire it up. Check with a light to see if you can see where it's leaking from (you might have to have someone else start the truck cause it could start leaking too fast for you to come around the truck and see where it's coming from) If the block is cracked I'd try some "The Right Stuff" it's black and gooie, and it rocks. Either way I'd pull the sender and use a bit of "TRS" on the sender. Good luck!

sapo · 11-11-09, 03:47 PM

well i guess i will take the sending unit out clean it good and try the teflon and thread sealer again i didnt see a crack so hopefully that was it well thats one of my leaks i just had the front oil seal replaced next will be power steering i guess thats what happens when you let them sit for a long time

sapo · 11-11-09, 03:50 PM

TRS is that a thread sealer

2ndGenToyotaFan · 11-11-09, 06:58 PM

TRS is "The Right Stuff" It's a gasket maker/silicon type stuff that works great! Comes in a tube that goes in a caulking gun.

Most machine shops have a setup for looking for cracks, it uses a thin fluorescent fluid and a light. Drive it over to one, hose it clean with brake clean, then have check it for a crack. Takes only a few mins.

toy4xfun · 11-12-09, 07:43 AM

i agree with klf at least you would know for sure and then you can pain over the fix, they might even be able to fix it right for you if it is cracked for a descent price.

sapo · 11-12-09, 11:02 AM

wow thanks i would of never thought of that i think i will do that 2day and i hope its not a crack thanks again
