L's Collection of Tech Tips

Steve I'm curios, what's L? I remember the color code as blue orange green brown slate White red black yellow violet. That's on cat 5 wire which I'm sure has nothing to do with automotive wiring. Teach me something new today.

The drill is a great help. I couldn't use it on the valve stem without removing the cam towers so I took the suction cup off the wooden handle and shoved a 3/8" male air coupler into it and then chucked it up, that works great.

Now I know why there's no acorns in my air filter housings anymore. I think I have a new pet, hopefully it's just a black snake. The head is small and the tip of the tail is long and pointed so I'm pretty sure it's non poisonous. I've had the cover on for so long there's no telling when it slithered out, I just pulled it back yesterday and saw the skin. When I first bought this car I turned the blower on and pieces of a skin blew out. So I'm thinking they like to get into there. I'm making a lot of noise so he'll leave if he is inside.

If it has one, what's the G3 filter look like at the tank?

You are right, it should read FULL when shorted together.

I've got the part number for the O-ring around the sending unit from Nissan. It's like $1.89. I'll dig it out when I get in from work later this morning.

Don't know if you've read this or not but you might find something useful in there, http://www.classiczcars.com/topic/44331-diy-how-to-recover-your-z-seats-lots-of-pictures/

So for my selfish benefit for right and wrong, what does the gauge do when the sending unit wires are joined together? Is that not zero resistance which shows EMPTY?

Old thread but I'll play! I use 20W 3in1 with the blue label.

I'm probably light years behind saying this, but have you sanded your thermotime sensor to look like new brass?

I was thinking if you put the two wires together it should peg on the empty side of the gauge? Could the clear lense be pushed up against the needle? Happened on one I bought, the guy kept finger tapping the actual gauge face trying to get it to work when the sending unit went bad.

I put new connectors on my '77 a few years ago. If my memory serves me right, when I wired them in the instructions said that the wires could be swapped around without damage, they were both 12 volts. The ECU sends a ground pulse? that tells them to fire. Not 100%, but pretty sure. Maybe one of our electrical gurus can say for sure.

This is something I've only seen done with camouflage on gun stocks and compound bows, Hydro Dip Graphics, never thought about car parts.

Okay, I see what you mean by 6-2-1, I was thinking you meant 6 into 1, just quick typing. Sounds good.

All your hard work has paid off, that looks really good! Congratulations.

But I'd make more money!

Hey Rossiz, I thought I'd share some information I've gotten from Jeff G 78 on his 02 sensor placement on the header. He just put one in, Innovate MTX-L 3844, and said there is very little room down there where the header runs against the tranny so the right angles of the bung are critical. I know I had to grind off some of the transmission so my 6 to 1 header would fit on my '77, it was touching before the grinding. I'll put up what he told me in a PM, hopefully he won't mind. "The bung comes with the kit. Most bungs are 1/2" tall, but the one that comes with the kit is 1" tall, so if you buy a bung, you might want to get a tall one. Get a plug if you don't plan to install the sensor right away. The instructions say that the O2 sensor tip should be flush with the inside of the collector to protect it which is the reason for the tall bung. The sensor body and lead wire with a 1" tall bung is very tall, so finding a spot where it fits is critical. It has a range of angles where it can be installed from vertical. I came very close to screwing up. I thought I had the angle right when I marked it, but I underestimated the length of the sensor plus the wire. I should have tipped it up a few more degrees. As it is, the sensor wire touches the transmission and could rub. I will add some convolute to protect it. The bung is also flat on both ends. You will want to grind the pipe end to create a saddle so it fits the shape of the pipe to make welding easier. It took 5 minutes with a die grinder to get the shape close. A friend TIG welded it for me.

If you'll pull the valve cover off and the fuel line that goes to the rail then actuate the pumps arm by hand it should shoot gas out. You could have a clogged banjo bolt filter on the front carb, the float valve may not be opening or closing (I can't remember which allows fuel to flow through). Just throwing some common issues around. You can check for fuel in the float chamber by sticking a straw down the overflow bung on the cover instead of pulling it off. I know it's easy to get them off but those blasted cork gaskets are a pain for me.

I actually thought about that after I got my new spring compressor set up for our heads, it's fun. I must admit the beers I was sucking down had me thinking about a lot of stuff. Siteunseen's Cylinder Head Shop Bartering Welcome

Thanks Mark. I've heard isopropyl alcohol, kerosene or mineral spirits. I will try this but honestly I didn't do the lapping properly. I only did a rough cut until the sound changed which in hindsight was just the grit wearing down. I'm not in any hurry especially now that the weather has finally loosened it's grip down here so I just picked up another set of valve seals and will do the lapping the right way then reassemble. I found some great spring compressors that make it soooo much easier it's almost fun.

I've got new set of seals coming in later today. I'm going to redo the lapping on all of them because I didn't read enough. I never did the fine grit finish. Lesson learned at $20 for another set of seals. I'm learning how to use my spring compressor too, that's a plus. That thing is fantastic once it's setup for our heads.

I can put a pen light down the runner and see light. It could be a bent valve but I'm going to lap the crap out of that little baby first. The springs are on nice and tight too. My thinking is what someone brought to my attention, maybe you?, about the cylinders compression with a leaking valve.

Get a wrecker service to say they've had it for 90 days and want to sale it for storage fees. There's a form they fill out, the state issues a title to the wrecker company. They sign the back and you carry it to the title department with a bill of sale then a title comes back in your name. Works in Alabama!
