Reported cause
The sump plates on these engines are slightly different and we have learned that the issue is compounded with that sump plate.

I have had my guardian installed for a couple of years now.

I will say that during our testing I found one instance where the factory sump plate was machined deeper and effected the installed depth of the MCD sensor.

Suggestion
I guess the good news is that when I dropped the oil pan for inspection and cleaning prior to installation as suggested, everything was clean as a whistle without any signs of ferrous or non-ferrous metal particles, the pickup tube was also completely clear, and the pan re-sealed with a minimum amount of loctite 5900 with zero leaks at the flange.

Suggestion
I can post a small modification that you can make to the sensor to solve the issue or we can replace your sensor with the generation 2 unit, no worries.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored.

I have just finished up the install of the IMS Guardian, but now the drain plug leaks. Never leaked when I used the OEM one or the Magnetic one I had.
I have torqued to the correct setting, used a different crush washer and have even put less torque on there and it still seeps.
Any thoughts or anyone else have this issue?
We haven't had any complaints of this.. I will say that during our testing I found one instance where the factory sump plate was machined deeper and effected the installed depth of the MCD sensor. This did cause a slight oil leak as it effected seating of the crush gasket.
Email is some pics of the leak and we can either give you some pointers or send you an altered MCD unit.
We only had the problem once.
BTW the first generation MCD used a non OEM, thicker crush gasket. These units must use this sealing gasket and we include a second spare gasket in the kits. If using any other crush gasket I'd expect a leak.
Jake must have a giant alarm bell hanging off his computer... get some sleep, brother!
(actually, thanks for being such an available asset, and not just for your customers)
Jake, since this uses a different crush washer than stock can you specify which crush washers we should be using?
Also I recently inquired about upgrading my imsg to have the 12V output. Basically from what I understand I need to uninstall the electronics unit and attached wiring, correct? Wish the unit had a wiring harness disconnect near the electronic unit so I wouldn't have to pull all the wiring out. Other than that I think its a great product especially for those with a re-manufactured engine.
Thanks
IF the unit is generation one you must use the sealing rings that are supplied. We supply two of these units in each of the first generation kits and they
can be reused
several times as they are much more robust than the OEM units. I have reused these a dozen times when we were testing the IMSG and haven't had any issues. We do have replacement sealing rings available for the generation one units.
Generation two units have an altered MCD that uses the OEM factory Porsche sealing ring so nothing special is required with these, however these sealing rings are one time use only.
Yes, we need "the black box" and the primary wire harness if you want this upgrade.
The "optional" 12V output was something that wasn't engineered into the system from the beginning. Only after we had a handful of purchasers request this so they could run external devices did we integrate it into the generation two units as an option.
We can upgrade existing generation one units to have the external output for 40.00 + shipping, but we need the primary wire harness and the black box. This requires a circuit board modification.
Thanks.. Like any product that continues to evolve we will create upgrades along the way. Some of these can be applied to existing units and others require a purchase of a new system.. Kinda like the guy that just bought an iPad2 and its already the former generation because the iPad3 is being released.
That said, the IMS Guardian Jr. is looking good for release in late April for those who have the 2005 and later cars. Its not as seamless to integrate and doesn't have all the bells and whistles, but it still warns of imminent engine failure in the same manner. Its even easier to install and cheaper with a tentative retail price of 199.00
I have the first gen unit. It has the thick washer. The drain plug does seem to go quite far into the recess of the sump plate. I thought maybe that was preventing it from sealing, but it seems that upon further inspection it is just barely clearing the sump plate structure.
I will try tomorrow to get some pics and see if maybe my torque wrench is off just enough to make it seep.
I just don't want to over tighten and kill the threads in that alum. plate.
Installation is complete on IMSG0807, and I have a small oil leak coming from the unit's oil drain plug. 2004 996 40th Anniversary, M96/01 engine. I had no previous oil leak problems. Any ideas? Different crush washer? Machined right?
First make sure that it is torqued correctly. What I found on mine is that I had to torque it and as I was getting close to the 37 ftlbs I believe it was like the wrench all of a sudden "gave" on me and I thought that I stripped the threads of the sump plate,but it turns out that the plug actually touches the side of the sump plate slightly and was causing it to bind.
Now, my leak has slowed, but I have yet to see that it actually stopped. Over the course of a week I may have a few drops on the ground where as before I had a very small puddle.
Jake, what do you think should be my (our) next moves? Ship us new plugs to try?
We have had 4 reports of slight leaks, all but one of them was an issue with the tightness of the sensor or te sensor contacting the inner diameter of the sump plate before the seating surface. In that one case we replaced the sensor and the issue was solved.
If you tightened the sensor ad te leak slowed, the issues is not the sensor, it's probably slight miasma honing of the sump plate that's effecting the sealing of the sensor. I can post a small modification that you can make to the sensor to solve the issue or we can replace your sensor with the generation 2 unit, no worries.
FYI two of the leak issues occurred on the anniversary edition cars. The sump plates on these engines are slightly different and we have learned that the issue is compounded with that sump plate. Try tightening the plug slightly and if that doesn't work we will modify a sensor and send to you.
Yes, tighten slightly more.. If using our install socket the torque value is 19lb/ft.
We have no problem replacing any leaky sensor under warranty or assisting anyone who need the plug slightly modified to better fit their sump plate. You can next day the sensor to us on our account, we will modify the outer diameter and next day it back. If we find that the sensor is faulty we will replace the sensor at no cost.
I just changed the oil in the 996 since installing the Guardian and as previously mentioned the drain plug was leaking very slightly and I could not get it to stop. Jake sent me a new plug and since I installed that one there has not been a leak at all. I noticed that there was a different style washer on the plug this time which makes sense given the tight space. I suspected that the oil washer was not seating properly because it was too big.
Also of note, there was not any metal bits attached to the magnetic part of the plug. All was good!
Jake,
Just sent you a PM, having this exact problem. Installed my new Guardian Jr. yesterday and there is a persistent slight drip when torqued to your spec. A bit of additional tightening didn't help. The car is a 2004 996 C2, non AE.
I guess the good news is that when I dropped the oil pan for inspection and cleaning prior to installation as suggested, everything was clean as a whistle without any signs of ferrous or non-ferrous metal particles, the pickup tube was also completely clear, and the pan re-sealed with a minimum amount of loctite 5900 with zero leaks at the flange.
Pfbz,
We received your email as well and have replied to it. We'll get you taken care of under warranty very quickly if necessary.
The email includes a couple of pointers that will probably solve the situation.
Sorry for the issue, but we'll help you through it.
Mr. Raby,
Had this leaking problem with my IMS Gaurdian since Oct 2012. We discussed blowing out threads and new crush washer which I tried. there was not a washer in my packaging when purchased. How can I obtain a replacement sensor and crush washer as this seems to be the solution?
[email removed]
if you will please contact me?Thx
Just shoot me an email and, we have no problem sending you some replacement washers for your generation of sensor, or providing any other support that you may need.
I bought the Guardian Jr. version for my 2006 987 Boxster S. The plug leaked from day one. I contact the company and they wanted photographic proof it was leaking. So eventually I purchased a second plug for something under $100 and that one leaked from day one as well. I now use 3 new compression washers and torque the @#$% out of it for it to not leak. It might be dry now and if I want it working I have to replace again. More puddles! Am about to purchase 3rd Junior plug as I am as paranoid as the next owner. Car has 160K.
No one ever offered to help me with my leak. Never believed me it was leaking. Now you all say no one ever complained...? Ever.
I love my car so I am stuck until I do a retro IMS bearing rebuild as my case has to be cracked to get to it. Maybe it is time instead of another plug...
If you were never offered any help, then you didn't contact the right people.
I have no problem sending you a replacement, but we need to receive the old units back. It doesn't even matter if the warranty is still active, get us the old units and I'll send you a free replacement.
That said, if you have multiple issues, the sump plate has a deficiency. I have seen a few of these that needed machining.. Pull the sump plate and we'll even machine it for you free of charge if you send it to us.
No problems. We've got you taken care of.
I have had my guardian installed for a couple of years now. It always leaked a little. The real problem is the epoxy filling where the wires come out disintegrated and the wires have become frayed just inside the plug this is now the case on my second plug. Anyone else have this problem. I was very careful both times to support the wires with zip ties so they were not hanging low or under stress.
Do you have a pic of how the wires were secured? The enemy is turbulent air under the car. If the wires can shuffle in the wind, then over time damage can. E done.
I tend to wrap the wites tight to the body of the sensor over 180 degrees of the sensor, then let the wire exit to the chassis.
I just dismantled everything in the process of changing the oil. Removing drain plug I noticed the epoxy missing from the wire insertion area and close inspection black covering on wires not secured to plug anymore internal wires each have nick in insulation. The wires were led straight forward and zip tied to remain straight and not hang down. I do drive the car in the winter slush and salt so it is a harsh inviroment, but I am only getting 5K miles out of each sensor so far.
