Since I made one fer my 1993 T-100, I've decided I want to put on on my 1998 T-100 as well.

I've already plumbed in some hoses to run both valve covers to their own separate catches.

Looks like I'll need to replace the PCV valve grommet that goes to the passenger (right) side of the engine since it's pretty hard to pull the PCV valve out and a quick check of the grommet confirmed it was hard as rock instead of that nice rubbery softness we've come to expect. The previous owner (PO) had mentioned the engine was eating about a quart of oil before I bought it. I didn't see any leaks from the valve covers so I immediately suspected the PCV valve was clogged. Seems I was right as the PCV valve was never changed...ever! I was able to scrape out the gunk and free the valve up. Cleaned it up with some carb cleaner and it will be good fer now.

I'm gonna go with some glass jars again (canning or spaghetti sauce) fer this truck as I have them and it's easy to see how much oil is gitting caught in there.

Some people will use those air compressor filters fer this sort of setup but I want to keep it basic.

What's yer thoughts?

I like the idea of the mason jar. I've never seen a catch that you could see the oil level on!

When you go shopping look for a real mason jar with graduations on the side. Maybe you can even find metric graduations?

I wonder about using an old Nalgene bottle as well. There should be tons of them cheap with BCP or whatever it's called. Then it would be indestructible and graduated.

Wow. I just looked at some catch cans online and figured out that the tube is for seeing the oil level. Doh.

Still, I stand by the Nalgene suggestion

 

[BamZipPow]

Well...the Classico spaghetti jars have lines fer every 4oz...

I know the 8oz glass baby bottles have graduations as well. I have a bunch of those...

Bam,
For whatever reason, I've never heard of an oil catch can system. Did some checking and seems interesting. Figure you woudn't be doing it unless it had merit. Found one article that uses an air compressor bowl as the can. see it here: http://www.pbase.com/rsrock/oil_catch_can Some interesting followup comments there as well (one guy suggests a T fitting for delivery of TB cleaner w/o disconnecting, etc)

Would like to see you follow up with pics, if you don't mind documenting. So does the PCN valve remain in place? Would also like to see where/how it's mounted.

 

[BamZipPow]

Yes...I will be keeping the PCV valve in place as I don't need more oil going through the system. I'll try my best at gitting piccies but I make no guarantees...

I'll be mounting my setup on the right side fender well. Some say glass isn't a good choice but it's what I have.

Here's what my original one that I installed on the 1993 T-100 looks like...

$3.00 oil catch can....

I found this on the internet.....I think I'll have to give this a try!!!

Finally transferred my spaghetti jar oil catch to my new T-100. It's only on the vent side (driver no PCV) of the engine. Gonna see what kind of crud will come off of that thing. I used some 1/2" ID and 5/16" ID hose to make my connections on that side of the engine. Fer the PCV valve side (passenger) I had to use some 1/4" ID hose (leftover from the fuel filter catch can) to adapt to the PCV valve as well as the TB inlet. Everything is snug as a bug in a rug...

I only have the hoses stuffed into each other fer now...it seemed to work just fine in my other T-100 so it should work fine here. I have the smaller hose stuffed in about a good ¾" into the bigger hose.





Gonna have to build another jar fer the PVC valve side and hook it up...

 

[BamZipPow]

I checked the jar yesterday...it was empty when I put it in place. After about 50 miles...there was about 2-4oz of water in the bottom...very interesting. I emptied it out and will see after the next run what kind of fluid I end up with.

Engine oil is not milkshake...currently in the 2nd cleaning phase with Auto-RX.

Close to building my 2nd catch can fer the PCV valve side of the engine...

 

[BamZipPow]

It's done...and even better than my spaghetti jar one!

I used a 16 oz wide mouth jelly jar. I modded the lid by drilling out some 1/2" holes, putting some 5/16" barbed adapters, 1/2" washers, and pipe couplers as securing nuts on the bottom of the lid. I had to drill out the washers a little so the threaded part of the barbs would go through. After tightening the barbs down, I glued the coroplast divider to the lid in order to keep the fumes separated from each chamber. This forces the fumes to go through the scrubber and the heavier particles will filter out of the fumes. The filtered fumes then git sucked up through the other chamber. As the filtered particles git cooler...they will eventually drop to the bottom of the jar. The assembled lid is very stiff and won't flex.

To assemble the oil catch jar, I put the stretched out scrubber on evenly top of the jar. Next...I shove the assembled lid down forcing the scrubber to fold in half. Making sure that there isn't any scrubber strands over the edge, I screw the retainer down snug. All I have to do now is hook up my hoses. It won't matter which end is which as my design allows either side to function in the same manner. To empty/clean the jar, you just have to unscrew the lid and pull off the glass part. Clean and replace.

Piccies...









Now I still have to figure out the best way to mount it but fer now it will git wrapped up in a towel and shoved in a corner of the engine bay. Time to build another one to replace the spaghetti jar version...

 

[BamZipPow]

Guess I should've measured a few things...

Gonna setup the driver's side (vent) with a 3/8" hose and barbs. The 5/16" hose/barbs will be off of the PCV valve (passenger) side...

 

[BamZipPow]

Finally got the 2nd one built and in place. Had to pick up some more stainless steel scrubbers and stick them in the 2nd jar. Now I'll git a chance to run on the highway and see how well it does...

Now I have to go and build one fer the 96 T-100...the temporary oil catch system ($3 Fram G2 fuel filter) is showing a lot of oil buildup coming off the PCV valve. Hopefully it will git most of the oil out of the recirculating airstream so it doesn't gum up the throttle body the way I found it when I got this truck.

When the Auto-RX is done doing it's job...maybe there won't be as much blow-by coming off the pistons...

 

[BamZipPow]

Cleaned up the hoses and rerouted the driver's side to bring it over to the passenger side. They are tucked in nice and neat and easy to see/access...

 

[BamZipPow]

I noticed that after driving 250 miles of city driving only (speeds around 40mph or less) that there was no oil in the PCV jar (on the right). But after some highway driving (speeds at 70mph) that I got about a good teaspoon worth of oil.

Tempted to put in a Fram G2 fuel filter down stream of oil catch jar and see how much stuff is gitting past the current configuration of the jar.

 

[BamZipPow]

Installed the Fram G2 fuel filter on the return hose to see what the jar is failing to capture going back to the throttle body. I might have to add some more stainless steel scrubbers to the jar to help with filter but not to the point where it chokes off the airflow through the jar.

 

[BamZipPow]

Okay...just over 1000 miles on the catch system...about 1oz of oil in the jar. The fuel filter definitely shows some discoloration from some oil vapor gitting by the main scrubber...as one would expect. But it's much cleaner going back into the throttle body. I've had it at full throttle at few times...just couldn't help it.

No residue in the other jar though...I'll still keep it in place just in case.

 

[Zuke76]

SO how are you going to fix the oil in the intake issue that you have discovered?

SO how are you going to fix the oil in the intake issue that you have discovered?

Yer not gonna be able to remove all the oil in the return airflow...my current setup will remove probably close to 99% with the added fuel filter in place.

I will still have to inspect/clean my throttle body but probably not anywhere as often as someone who doesn't have this type of setup in place. Of course...I'll have to empty out my jar just as often rather than tearing apart the throttle body to clean out the gunk instead...but I think it's a good trade off...

 

[BamZipPow]

Just changed out the oil in preparation fer my road trip...there was about 1oz of oil/condensation/gunk in the jar. Quite smelly, too!

I think I'll just empty/clean the jar when I do oil changes. It seems to be working just fine.

 

[BamZipPow]

Just pulled the throttle body off to take a peek...just a slight oil film in the air plenum (probably before I got the fuel filter inline) and no significant amount of crud/dirt/carbon buildup. I took this time to put in the "O" type throttle body gasket instead of the "D" shaped factory throttle body gasket. Time will tell if this makes any difference.

In all...I'm still happy with the oil catch system...especially the disposable fuel filter I have inline after the jar. I can probably replace that every 6 to 12 months.
