Oilguard

[Silver]

I started to put in my oilguard EPS-20 this afternoon. Everything was going fine until the very last step. I had bought the cummins installation kit that runs the return line back into the oil drain plug. Well the plug DOESN"T FIT! So I figured screw it, I'll just run the return line into the oil filler cap. While drilling the cap, it broke in half. (I had the vise too tight) So I kept my cool and went to the parts store and picked up a new one. I drilled it, tapped it, made it look nice, etc. So I went to install it, and sure enough- not enough hood clearance! I gave up on it for today.



So now I wasted a whole afternoon, 12 qts of oil, and 2 oil filler caps. I am ****** OFF.



Anyway, what do you think about just drilling and tapping the valve cover for the return line? Is the valve cover thick enough? Should I go in through the top or the side?



(I know about Amsoil's swivel kit, but it seems a little half-@ssed to me. I want to use my whole @ss on this one

)



Thanks, Marc

don't know what year you have but check the turbo oil return line to the oil pan just below the oil filter. There is a 3/4" rubber hose between two metal lines that you can splice into with a tee and return your oil there.

Thanks Bill,



I looked at that for a while too. I might go that route- I need to think about it some more.

return line

I use the filler cap with the amsoil swivel. I thought that it was kinda cheap until i actually put it together. Its pretty good and the swivel is nice cuz u dont have to worry about kinking the hose removing the cap, plus no clearance problems, plus u can pull the cap with the engine running and check on the flow. If you have questions Amsoilman could answer them for u. I got the instructions from him on the cap mod. Was very easy and only took 15 minutes, but i let the JB Weld dry overnight. I'm happy with it.



BTW I have no affiliation with Amsoil, other than a user.



just my 2 cents.

I just installed my bypass filter 2 weeks ago on a 1996 2500. After studying all my options I chose to tap the return line in the first valve cover. I located the fitting in the front of the cover, centered vertically, offset all the way over to the drivers side, just before the curve of the corner. I used a 1/4 inch pipe tap for the threads, then used a 90 degree brass fitting. 1/4" male to 1/4 barbed. I'm very pleased with the results.



Just take your time & make sure you tap into the cover in a place that will give you enough clearance for the fitting when you screw it in. My fitting penetrates the inside of the valve cover about 3/8"



Best regards,



Mac

Oil Return Line...

Have it return directly to the block.

I looked at that location too. What is used to plug the block there? I was hoping it was a threaded plug, but it felt like a freeze plug. If it's a freeze plug, I don't want to mess with dropping the oil pan to make sure I catch all the shavings from tapping it. Please reply. Thanks, Marc

Not long ago somebody suggested a plug you can use. The directions were "Look under your turbo, straight down near the seam of the oil pan there is a plug you can pull for a return on the oil. " I just cut this out and saved it, I haven't gone any further than that, so I'm not real sure about where it is or if it works. I'm thinking about mounting a bypass this summer so I follow the bypass threads. Let us know what you end up with, would you? Thanks.

Remove soft plug and install 3/8" barbed push to connect x 3/8" smooth male fitting. Oil pan removal not required.

I ran my return line up the front cover and used to self tapping fitting to go into the side of the oil filler tube. Just had to get a 90 degree elbow from hardware store. Its also nice to be able to see how much oil is going through the bypass filter by looking down the filler tube.

Thanks JC

Thanks for all the replys. I'm going to go with JC's method.

 

[Clinton]

You're saying jc(brown) and the method demonstrated in the photo, not JC(yrbok) and the Amsoil fitting, right? Where exactly is that soft plug and casting? Thanks.

Correct. Soft plug is steel. Located to right rear of block.

Thanks jcbrown. Bear with me, I'm trying to make sure I've got your method straight... this plug is on the top or bottom of the block? Also, where did you mount your bypass? I would like to mount mine on the cross member below the radiator. I'm trying to collect potential return points to give myself some options (and hopefully cut down on the length of my hose runs). Thanks.

Located on bottom of block.



Bypass filter is welded to frame next to this location as well. Rear of axle disconnect.

Alright, got it! I'm thinking that is the plug I posted about earlier on this thread and was hoping to use. I was looking at mounting to the frame and wondering about going through the boxed section. I'm still not sure about location, but I'll probably be using that plug. Thanks again.

What did you use to get the plug out of the block?

I did it the wrong way. Do not use a punch. Plug is still in my oil pan. :--)



Bend edge of plug with screwdriver and pull out with a pair of plier's.

Oilguard called today and offered to send me the correct fitting. I had never bothered to call Oilguard to get the correct fitting, but someone sent them this message. The guy said he searched through his records and found me. I bought the Oilguard four months ago and they still went through the trouble of finding me and trying to correct the situation. That's pretty good customer service!



PS. Apparently the 2001 and 2002 CTDs have different drain plug sizes.
