New here. Don't care if flamed or not. while I'm sure your JB Weld solution to the oil sender will not leak, I'm not entirely sure the engine will like any trash that might break loose. My solution was to disassemble the factory MB oil sender. Find a matching hex head nut to protect the thread while doing this work, it should be M12x1.5, we found one in the MB pile,o,parts. The first step involves a die grinder and bench grinder to remove the rolled edge. After that step systematically destroy everything but the threads and the hex cap portion via bench grinder. Wire brush, clean for next step. Drill a 11/32 pilot for a 1/8 npt tap making sure to check for depth as you go so as not to get into the shoulder and threaded area. You will want to keep withing the hex cap area. Trim off 40% of the bottom of a 1/8 npt tap and put a slight taper on it. An unmodified tap will bottom out before cutting the correct threads for a 1/8 npt fitting Wire brush said tap and clean. Tap, checking as you go for depth and fit. Wala you saved $23 plus shipping and spent $3 on a fitting and $10 for a tap, however you didn't have to order off of mercedes4x4.com's unsecured website or deal with trying to get ahold of him on the phone or email him. Just my 2 cents.

I understand your concern regarding the JB weld, welcome to the forum. |
Opened mouth before reading gentlemen. Looked at the text in your post regarding brazing. My apologies.

I was pulling the V8 out of the Wrangler yesterday and thinking about your mod for the Tach. It took a while but I finally figured out I won't need to do that because I'm using a Wrangler flywheel and bell housing. You had to adapt because of the GM automatic. I'll still need to make the cam sensor mod though. Am I correct? Also, what kind of tubing did you use on the injector returns?

A lot of people use a relay triggered by the starter for this, which is what I originally did, but I was thinking about it last night and couldn't see any reason why it would need to be disconnected after starting. I connected the signal wires together directly and it works just fine. Much simpler! |

The tubing is called Tygon tubing otherwise known as lawn mower fuel line, this line is frequently used for diesel return lines due to its compatibility with diesel. The correct tubing can be found at VW and Mercedes dealerships, I will be replacing them with it soon. ---AutoMerged DoublePost---

The PCM just needs to see a signal from the cam sensor on startup to turn on the tach. It doesn't check for accuracy, just presence, so you just need to tie the signal wire from the cam sensor into the signal wire from the crank sensor.

Been fixing odds and ends. Back from the junk yard with new to me interior trim pieces.
Just completed the wiring for the AC, 78* outside 32* out the vents! you can see all the plastic on the dash is intact now. Attachment 33156 Attachment 33157 Attachment 33158 Attachment 33159 Flexed out the Jeep to make sure no suspension components come close to the oil pan, they didn't come close so no worries for now. I'm not to happy with the flex with the sway bar connected so I've ordered a set of JKR quicker disconnects and will post comparison pics when I install them. Attachment 33160 Been prepping and tying loose ends up for this, any Bombers going to be there besides me? Anyone know where I can get a sticker to rep this site before the date? |
Man great Work! I just need a few more things so I
can get started as well! |
Thank you, be sure to start a build thread when you get started.

You taunt me with your A/C! Here in AZ, I really want to get that installed before summer hits too hard!
