Oil pressure sender
 

Engine was running decent after its first start up from a rebuild but notice oil pressure dropping dramatically so stopped engine and my damn oil pressure sensor is pouring from the threads Not leaking, POURING. I then replaced the sensor and that didn’t help. I did take the sensor off when i got the timing cover cleaned i may have over tightened and damaged thread size. any solutions? I do have pressures gauges https://uploads.tapatalk-cdn.com/202...d54b52a8de.jpg

Over-torqued and cracked?

Well that sucks! Where is HUMFRS? I bet Buba is going to recommend som JB weld.

I have a spare timing cover I was going to use for a project you can have for free, just pay shipping. PM me if you want it.

Nooooooo!

Loving the MCB mentality ;)

Done well, this can actually work. Fixed a coolant sensor port on a salvage yard cobra intake this way.

+1 I was shocked when a buddy fixed a cracked iron block with it. Lasted at least a year. Then I moved away. Lost track.

I will jump on this bandwagon as well. If done properly it means taking it off, cleaning the living hell outta it, applying exactly the right amount to fill the crack, tapping the thread and reinstalling it.

So at that point you may as well just replace it. Especially when a free one is offered up!

Amen to all of the above. I'll review for the record. This is without judgement. We've all learned lessons the hard way.

OP either wasn't aware of, or greatly underestimated the wedging action of a tapered thread. The temp sensor was also way over-torqued. We can see that it's bottomed out. There are torque values published for these fittings but in reality, they only need to be tightened until there's a smidge of resistance. The thread sealant will do the rest. If the threads are in good shape, and are clean, might even get away with skipping the sealant.

Most service-related damage comes from over-torquing or cross-threading fasteners. Even "experienced" mechanics rarely appreciate how much care it takes to reuse threaded joints without damaging them. This is especially true for steel screws in soft aluminum.

Two actually. OP ended up getting another one for free locally. At least my spare is now nicely packaged for storage now :D
