Engine/Transmission (1998.5 - 2002) Catch can

[garylmoore]

I am tired of my truck dripping blow by residue everywhere. What is anyone out there using as a catch can? I know that there are Catch cans that you can buy but I've also seen where people have made their own.. I want to stop dripping on my driveway, how do I do it?
Thanks

So no one has fabbed or used a commercial catch can before? I am hosed to the back of the engine, but I am trying to stop the drip. I am willing to consider any commercial or homemade fix that will not blow my head gasket. Any help appreciated please.

There are MANY threads and posts about catch cans, just need to search.

Racor had a kit for the 24V engines.

I would have thought so too, but every time I search I get zero results. I cannot even get this post to show in results and it is named "Catch Can"

Thank you..

There are some pretty cool ideas folks have used.
I think peanut butter jars, Gatorade bottles, pretty much anything could be used.

Not fun if search won't work for you.

It back in the day was noted to not extend the hose to far if you live in a Northern winter freezing area, and the condensation will freeze and keep freezing until the outlet is plugged and then you blow seals in the engine.

That’s what I got when I searched, too.

Longer hose blew my front seal out. 15 -20 below beware. Ouch $ $ $ painful

I added this to my 01 Sport after removing my radiator and cleaning it and the entire engine compartment of old oil and grime. It's made by Peak Diesel that is owned by Piers Harry and Harry ? in Canada. I ordered mine thru Harry.

I have to say I am more than disappointed as the rubber radiator hose was junk as it collapsed with any bending so I came up with a much better quality hose and a 90 degree fitting at the front of the engine. I routed the line to the drivers side inside front fender and made a bracket so the catch can would stay vertical. It dripped out of the filter as it became saturated. So I put an exhaust band clamp around it with sealant but that also leaks and I still get a drip on the ground. Not sure what else I can do.

Can’t find pic of band clamp but it’s around the lower portion of the filter. Guess the oil is still running down the pleats and past the thin band clamp.

Check your vacuum system to make sure it doesn't have any leaks, that can contribute to drips. My 24V came from the factory with the tappet cover crankcase vent. When I replaced the gasket on the cover I enlarged the hose fitting and put a larger diameter hose on it. With crankcase gasses coming out at a lower rate I never get a drip on the driveway, with 276,000 miles on my truck.

I have wondered why Cummins switched to the front crankcase vent. . . didn't solve any problems that I can see, but created at least two problems. . . caking up the radiator and blowing oil out when 4-wheeling down an extreme steep grade.

THIS has worked for me, for years - the extended hose and drilled container are obvious - the outer covering to absorb oil is old socks - I only need to change the sock every other oil change or so, easy to do when I'm under the truck changing oil anyway - later on, I have used stainless steel clamps instead of cable ties all is tied to front sway bar - no problems staying in place - and absolutely NO oil buildup on back of radiator OR on garage floor...

Really? You have oil coming out of the pleats on the can vent? I will not be happy if I still have dripping oil once i complete this install.
I bought the same Peak kit for my truck and started the installation this weekend.
I could not find a suitable mounting spot anywhere near the engine compartment, so I mounted the can on the drivers inside frame rail about where the driver and rear door separate. The mounting of the can was a pain. the steel frame was hard as hammered hell, but only an 1/8" thick. I ended up drilling and tapping the rail with a 3800 rpm drill to get the bit to run fast enough to cut. After tapping the thru hole, I ended up with only 3 threads in each. I do not think I can get a nut on the back inside of the rail, little access. I will just locktite and lock washer the 1/4-20's and hope for the best. I may zip tie the bracket to the frame as added insurance.
Long ago I eliminated the hose and catch bottle at the front crankcase vent, replaced the radiator and cleaned everything up. I ran PVC across the top of the engine (as I had seen done in other threads here) and just let it drip down under the fire wall. If it weren't for getting the mess on the drive, that would be ok. . My truck has "Corrosion Free Anti Rust" applied yearly (IT REALLY WORKS) so it is oily under there all the time anyway. This tube did it's job well, the front of the engine, all the pulleys and the radiator are still clean after 80k. I am going to pull the PVC homemade vent tube today and try to figure if I need to go direct from the vent to the catch can or if I can just hook to the PVC pipe hanging down in back of the engine. MY only worry is back pressure.
Any idea on that guys?

 

[garylmoore]

How often do I need to change the green serpentine belt at the front of the engine? I believe this one has been on about 80,000 miles. I will have to check records to be sure.
Thanks for the advice and help guys... Gary Moore

I am in a cold weather area. We hit -15 this winter and -30 the previous. I stop driving the truck at -15, no guarantee I am not going to freeze up going down the road regardless what antigel I put in the tank.
Man, I crawled over, under everywhere on that truck and could not find anything near the engine compartment where the catch can would fit. The closest place was under the plastic bottle by the passenger front fender, but was afraid I would rub the torsion bar in that position.
How much movement do I get in the torsion bar where it curves left and goes across the front of the truck? Mounting it there gives me about a 1/4" clearance from the vent filter touching the torsion bar. That would be the best alternate mounting place I can see. Thanks.. Gary

In cold areas a real concern is the condensation freezing in the breather tube, plugging it and then you blow engine seals. I would not extend it in such a cold area.

I will go out and look again. The only other place I see it working is under the coolant reservoir on the right side. I would like to run the hose over the radiator to go across, but that would put the hose above the vent and I'm guessing that is a bad idea. Gary

Talking to my son recently about how my pleated vent still allows oil to accumulate and get the occasional drip. We discussed removing the pleated vent and mounting it up higher like near the brake master cylinder. Maybe doing that will keep the oil mist from getting to the filter.

Thoughts?
