He Box that connects from engine side to intake? Anybody know what’s it called
lp with part
if you broke it, it's not sold separately from the intake system. You'll need to find used. Theres nothing inside so I'd just replace with a brass pipe fitting or another plastic fitting. Not sure what it's called but it doesn't serve a function other than to flow air from intake pipes to valve cover
What would you recommend? I tried a hose but not all bend.
I used a chapstick tube and called it a day. It basically acted as the little box thing. You could even plug the intake holes. I've since done away and plugged both intake tube holes I used old o2 sensor bung bolts. Perfect fit seal and head with no chance of coming off. Can even reuse the oem clamps
That part is an "oil vapour separator" and it is part of the crankcase ventilation system. The intake Helmholtz resonator is under the rubber intake boot.
Its purpose is to filter out any oil droplets and vapours before it enters the intake system when the engine is under mid to high load.
If you plug the hole in the intake boot and add a filter to the valve cover, you are venting the crankcase to the atmosphere and that will increase crankcase pressure.
For a stock engine, at low to mid engine load, the crankcase pressure is slightly negative. This helps to remove the oil and water vapour from the crankcase.
If this was my car, I would get the part from the scrap yard, or buy the entire boot from ebay.
I just ended up taking it off and plugging it with a vacuum cap and lots of electrical tape. It’s not a pretty job, but it’s what I did. Am I harming my engine allowing oil droplets enter the manifold?
