Oil pressure sending unit crack block?

[unior]

I have recently heard that people have been cracking blocks by hanging a heavy electrical sending unit off of the oil filter housing.....

I am about to finish up an autometer electric oil pressure gauge installation.....wondering if anyone has heard of cracked blocks?

I know this doesn't help, but you are the first person in my three years of dsm experience that I have heard say that. It is a cast iron block which would take alot to break. I wouldn't worry about it.

well i read it on a mirage forum - now i think they were talking about the 4g15 12 valve motor

IF it's happening, it's from over-tightening the tapered threads on the sender, not the "weight".

what can and has happened to me is if you were to hang a distributor block off there so you could also keep your factory gauge. Then that can break at the threads and leave the threaded section in you filter housing. It's also a real good idea with autometer gauges to remotely mount the sending unit. the vibrations from the motor kills them pretty quick. and there like forty bucks a pop.

You're talking about the oil filter housing? I broke mine on my 2g. That piece isn't iron on the 2g, it's aluminum. I was putting my sending unit back in, and like a dumbass didn't realize it's not supposed to thread down flush with the oil filter housing. I threaded it in too far and cracked the whole oil filter housing. It sucks to have to replace that thing, so be careful.

If you're using a brass adapter T to connect both the original and new oil pressure sensor, I've heard of brass being more susceptible to cracking than stainless steel. I've seen some installations where a rubber or braided line was used off the T and run to the pressure sensor mounted somewhere in the engine bay. It's a little more expensive but solves the problem of having the weight of the new and old sensor hanging off a 1/8 fittiing.

You should be able to use a 90 degree male 1/8" BSPT to 1/8" NPT adapter on one of the unused filter housing ports, a 1/8" NPT to -4 AN adapter, -4 socketless connector a few feet of Aeroquip pushlock blue hose, another -4 socketless connector, another 1/8" NPT to -4 AN adapter and an 1/8" female to female connector. Should cost less than $30.

Yeah. I have apples for sale, too. $1 million dollars, each.

For some reason, people seem to be buying their apples somewhere else.

Then again, I only have to sell one.

You might try another shop for that line.
