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:frown:
 
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

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:steer:
 
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!
 
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
 
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.
 
hey guys i am back and still with the same problem i took it in to a shop and they said i has a crack they tapped and put a plug they said to drive it around if it started to leak again they would have to take the engine out and grind off that part of the block but that you cant weld on cast iron what do you guys think :confused:
