Are HPD catch cans any good?

The HPD catch can was the forth worst performer. Consider this a Catch Can Comparison test, with the major brands tested. To make things worse, it wasn’t even remotely close to the performance of many of its competitors. In terms of a catch can review, the HPD faired very poorly.

How does a HPD catch can work?

HPD has tackled this problem with our catch can. The catch can is an oil/air separator that is mounted between the breather and the intake. Its four fine stainless steel mesh filters capture the fine vapour before it gets to your intake, reducing buildup over the life of the vehicle.

Are cheap oil catch cans worth it?

The answer is yes. While a catch can won’t stop every last particle of contaminant from entering the intake manifold and coating the valves in a direct-injection engine, the less unwanted buildup the better. So, yes, a catch can isn’t a bad idea. At a minimum, it’s not a scam.

How often do you empty oil catch can?

For environments that will have winter months in sub-zero climates, an oil catch can should be drained out. Some owners may prefer to take the actual can off for the winter. How often do I drain my Oil Catch Can? The general recommendation is with each oil change.

Should I install an oil catch can?

Is it necessary? Strictly speaking, any car can continue to run without an oil catch can. However, if you do not install one, you have to take other steps to deal with the effects of blowby in your vehicle. One is the removal of the manifold in the DFI engine so the deposits can be cleaned off.

Is an oil catch can legal?

Although a catch can could help your car’s engine run well for a long time, modifying the PCV system is illegal since it’s part of the engine’s emissions system. If a technician were to see an oil catch can installed on your car while performing an emissions test, they may fail you on the spot.

Do you really need a catch can?

When it comes to the question of whether or not you need an oil catch can, the guiding principle should always be the amount of oil that the vehicle uses, or the amount of oil that is present in the inlet tract. Therefore, unless there is liquid oil anywhere in the inlet tract, you do not need an oil catch can.

What happens if your catch can is full?

If the can gets full, you will suck liquid in. It will be worse than running without a catch can.

How much oil does the HPD catch can catch?

I ran the HPD catch can on my Dmax for 34,000km. It caught 125ml of oil (eye balled; 97 grams of oil), which works out to be 37ml every 10,000km. I then removed it and installed a Provent 200. I’ve collected every drop of oil from the Provent 200 (like the HPD above) and put it into a container over the 5625km I’ve had it on for.

Does your D-Max need an HPD catch-can?

Once bitten, twice shy, so the D-MAX was the recipient of an HPD catch-can soon after taking delivery of it nearly four years ago. Since then the vehicle’s travelled just over 100,000kms trouble-free, and periodically I’ll drop the canister and wash it out.

What is the difference between proprovent and HPD catch cans?

Provent catch cans come with a relief valve that opens if the pressure builds up too much. HPD have nothing like this, but because the filters are much less fine the chances of back pressure is substantially less. There is a chance of the dipstick on the HPD popping out under pressure, as long as the hose outlets aren’t over the top of it.

Should I buy the HPD catch or the Provent 200?

Interestingly, the HPD catch can caught a reasonable amount of water. I can’t be sure, but its possibly condensation from the aluminium heating and cooling, as I get none of that with the Provent 200. What’s even more disappointing is the HPD Catch can actually costs more money than the Provent 200, right out of the box.
