1999 4.0l OHV catchcan?

[RussAdams]

Has anyone put a catchcan on their 4.0l OHV?

I seem to have two places a catchcan could be useful:

1. Drivers valve cover PCV valve to intake manifold.

2. Passenger valve cover has a return hose from the oil filler neck to the air intake throttle hose.

Could I route both to a single catchcan? If so, where should I end it? PVC or throttle air hose? Or use a couple Y connectors and reconnect to both, but run both through the same catchcan?

Or just get two catchcans?

I have one on each location.

The clean air side on the passenger side of the motor going from valve cover to intake tube used to suck a fair amount of oil into the tube. It no longer does that and the can actually stays clean. So my assumption is that the extra length of hose and the fact my can is slightly higher elevation than the valve cover side of the hose lets whatever oil that might gravity drip into the can. Drip back into the valve cover which is great!

The driver side where the PVC valve is routed to the intake gets very nasty fast! I can probably collect half a shot glass of oil in 800-1000 miles. Which is nice to know it’s not going into the engine.

Both cans I have are super cheap ones on Amazon. I have tested many very expensive cans vs these and for a low power motor like the 4.0 OHV these work great for low cost.

Great! Thanks for the through reply!

Did the kits come with enough hose to install? Or did you have to buy more?

The hose they came with was straight garbage, I through it away and bought some stuff at a local auto store. A nice thing about those cans is they come with enough fittings to use many different sized hoses. IIRC the clean air side is much larger than the PVC side.

Cool. I'll plan on buying more hose.

When you get them installed let me know the collection results! I’m hoping yours catches as much was mine meaning my motor isn’t as bad as I suspect lol.

Will do!

Do you have photos of where you mounted yours?

I’ll get you some soon if I can remember. I made a mount in the driver side for the PVC can but passenger side it’s currently just a dangly dude jammed in a hole kinda by the hood hinge. Plans to make it a mount are all ready in the works.

I promised pictures but I didn’t promise good ones lol.

Not a great picture, but I used some 3/4" (maybe 5/8?) transmission hose, a heater hose Y, and a plastic strainer housing for a farm sprayer. I stuffed some coarse stainless steel wool in the strainer to slow it down some more. I have it vented back into the snorkel. but could probably just go to atmosphere. The whole thing just kind of sits in the space between the AC filter/drier and the blower motor housing.

Don’t see pics of those blower setups often, nice engine bay sir!

Wow! That is one full engine bay!

Great stuff!

Thanks for sharing

Did you connect to just the oil filler tube on the passenger valve cover?

Or did you connect to the driver's side PVC valve? Did you block off the driver's side intake manifold?

Or both?

Not quite sure where you put everything.

Would you please give me some more details?

Its connected to the filler neck of the passenger valve cover and the factory PCV location on the Driver side, then the hoses Y together on the way to the catch can. I dont have the factory intake tube or manifold to worry about.
