I'm about to install some gauges, one of which is a mechanical oil pressure gauge. Doing some research before even installing it, I think I'm going to need some more supplies. I'm assuming from what I found that the oem oil pressure switch (controls warning light) is a BSPT thread on the block. The connectors included with the kit are 1/8 NPT. SO it looks like I will need a female NPT to male BSPT adapter. Can I buy this adapter in Lowes or Home Depot? Where else can I find it? I'm sure some of you have run into this situation when running oil lines for your turbos.

 

Tried Lowes today with no luck. Found a website that has em for 10 bucks. However if you ever are going turbo, Tunertoys.com has a nice one that has the BSPT adapter, allowing you to use your factory oil pressure switch along with 2 NPT hookups for your turbo oil line and an oil pressure gauge.

 

in the future i would say to run a electrical oil gauge since if your mechanical gauge ever breaks that thin line...you will have oil all over your pant lag or inside your car.

 

Yeah I knew the difference before I bought this set. Although I've heard about how the line can break, I've never heard from someone who installed it RIGHT that they had ended up with a broken line, and oil everywhere. Mechanical vs Electrical in a nutshell; Mechanical are way more accurate, and of course cheaper.

 

Just got to advance auto or autozone and get the copper line to replace the plastic one if your worried. A 8 foot line is like 10$.

 

also i woulod look into an oil filter sandwhich. you can get them on ebay for like 30 or so bucks. they have three ports on them and they sit right inbetween the oil filter and your block. those three ports can be used for anything that needs oil.....turbo lines, gauges, etc... this way you dont need to drill or tap anything. http://cgi.ebay.com/ebaymotors/OIL-F...QQcmdZViewItem

This isn't too old to drag up, but I have in fact seen what happens when those little plastic lines break. Happened on my buddy's '70 Buick Skylark, 502ci big block. Line was routed along the block, away from the headers (as much as possible, never was a problem before), but when the cam ground down on break in, the headers got red hot (cam timing was off a little....), melted the line (obviously it was too close to the header at this point :exnbp, after the line melted the oil started squirting out, right on to the header. Next thing you know, *poof* oil fire. Everybody running around like crazy :run: not knowing what to do, finally someone grabbed a fire extinguisher. By that time the fire had gotten 4-5 feet high out of the engine bay, and burned the distrubtor wiring enough that it grounded out, and killed the motor. Lucky that happened cause it just kept spewing oil out of that little broken tube, right onto the header. Funny part about it was it only lasted like 15 seconds, but seemed like 5 minutes, and you couldn't hear a damned thing over the sound of that 502 at 2k rpm! But hey we all made it out fine, and the car only lost the booster and some wiring, so all in all not a horrible day. :cheers:

Of course this is the worst case scenario (except no one was cooked like cajun food), but hey, it does happen. After being there through that one, I can't fathom a reason not to spend a few extra bucks to get an electric gauge. But hey, I drink and have unprotected sex, so I guess we all take our chances right? I'd just rather not burn to death.

 

Thanks for the warning. I've had mine in for almost a month now, no leaks at all. Also this line comes out of the back of the engine at the oil pressure sender, I don't believe there is anything that hot back there.
