New oil catch can thread

Most of the threads are at least 10 years old. Thought maybe an update was in order. Any new opinions and/ or results? Just installed the JLT can on the turbo shield. Haven't tested it out yet.

If that is Mike "Spoolfool2" Barnard's then yes, it will work. If not Spoolfool's it may or may not work.

Mike just brought them out about 3 months back and his is a oil drip collector to keep hot oil from dripping from the right passenger rear corner of the motor onto the hot header. (I think). My bad from misinterpreting your thread query.

If that's a can that unscrews from the bottom, and it's aluminum, that ends up being a terrible spot.

The heat from the turbo and the exhaust will release the lower section, it'll unscrew itself, and fall off. Been there, done that, moved it to a bracket hanging over the intercooler.

I would not put a catch can that close to the turbo either. I just think there are better locations.

This thread is only 7 years old ;)-

Thanks! I didn't realize 60 was considered to be so young! I put it on the turbo shield screw for simplicity. I guess I'll have to rethink that location.

I just got done putting a hose clamp around the can so it can't unscrew and fall off. I wedged the hose clamp between the can's bracket and the turbo shield screw. This way when I loosen the hose clamp to unscrew the can, the clamp won't fall off. I even tested my handiwork by unscrewing the two little screws holding the can to the bracket. The can barely dropped. I thought somebody would ask why I put an 1126 (from AutoZone) pcv valve in line instead of a check valve from US Plastics. Well, the pcv valve is metal. Last time I used a check valve from USP it was plastic and fell apart from the heat. Does the 1126 valve stop all pressure completely? No. Will some pressure get past the valve into the can and back out the other side? Probably. So that's why I started this thread...to get long term results from the guys from 7-10 years ago. One more thing...sorry, us 60 year olds used to watch Columbo.... the pcv valve accepts a 3/8" hose on one side and a 5/8" hose on the other side. This is perfect for the JLT catch can as it requires 5/8" hose. Or 1/2" hose, not sure which.

I’m running a nice powder coated black aluminum check valve in between my catch can & Plenum from Boomba racing

My JTL has never unscrewed itself. That location sucks. I have looked at those Bomba valves but every time I look the 3/8" is out of stock.

Oh, only the fact the turbo gets to be red hot every time you go wot. A catch can works by separating moisture and solid oil from the fumes that get sucked back into the intake. Typically the fumes going in are run through a mesh or channels which the fogged oil will get trapped on and then drip down into the can. Moisture is cooled enough for it to also get caught on the mesh and drip down to the can. Mount that can in a super hot spot and you defeat how it works. Even if it works for a little while when the turbo shield area is "cool" any oil and moisture will get boiled out eventually. That crud will then be sent right into the intake which is what you are trying to stop in the first place.

Thanks for the explanation!

I run a used Elite E2 from a Denali 6.2 on my Buick, over on the fender where the washer fluid/stock airbox used to be.

Great mod. Every TB should have one. Run it off the pcv to meter the flow. Mine is a Mishimoto compact can.

Here's my setup with pushlock fittings. I have an RJC check valve in the manifold and another check calve in the line going to the manifold to prevent pressurizing the can under boost.

I was reading where the newer Camaros have a catch can that drains back into the oil pan so you never have to drain it. Apparently GM engineers figured whatever is caught in the can, can be reused.
