Thread: Aircleaner mod for turbo

I've utilised some reduction tubing and an old baby bottle which is shatterproof, heat resistant and transparent. This allows me an easy visual check when the bonnet is up (which is virtually never, and definately never in public). I believe the ADF have a similar setup which probably cost megabucks. I never did trust the old dust extractor to be secure when I'm up to the doors. The whole system is now completely watertight including the canister lid. I know, it's been up to there, and further!.

For What its worth, i had to remove the dust ejection port on the aircleaner housing in order to move the housing well across to the right to allow a proper hose set up between the turbo and the aircleaner (engine is a 4BD1T). During the last 14 months the vehicle has done 80000+ks in the outboack in very dusty conditions (dust-storms, very heavy bull-dust, etc etc) without any dust build up [roblems at all.

I have thought of re-instating the dust port but have not yet got to it. I do have a 3 inch in-line water separator (of my own manufacture) fitted between the snorkle and the air-cleaner which seems to get rid of some of the heavier dust as well.

I'd be interested to know what your setup is.

I don't have a snorkel yet. The intake on the canister is on the same end of the canister as original, just rotated around. As the canister is flipped the canister intake is now on the passenger side. So the intake hose goes under the 90 degree bend (to the turbo) and along the passenger side guard. I plan to route it back to the driver side and to a snorkel.

Great set up Gerry. What does it reduce to. I don't think we have any baby bottles anymore. Does dust accumulate in the bottle?

Its a bit nerve when the water covers the bonnet.

Reducing from the normal dust outlet diameter (I think about 75mm?) to the baby bottle (48mm??). It has collected some debri, about 40ml (yes it has a level) over the last 6 months of dry weather. I do check the level on a regular basis, and John is correct, even with a ram snorkle head in heavy rain, very little moisture is accumulated in the apenage. The rest of the system, leading into the air filter canister, is a mix of 75mm aluminium tubing and silicon tube. I don't trust flexiduct as the engine vibration wears holes through it easily and very quickly.

NB.....When my Landy was NA, I was worried about water ingestion via the dust valve, so I blocked it up, basically welding a cap over the hole. When we came to remove it during the engine swap some months later, we found moisture had caused rust to develop inside the canister and apenage. The car had been used month on month off as per my work requirements, but I thought it would definately become an issue over time.

Not at all Pete, your asking the question I was thinking!

IMHO, the opening would nave no impact on cabin noise. That said, I'd also prefer not to modify my housing, if I don't have to.

Mine has a big impact on noise. I didn't have a duck bill fitted and when I finally put one on the noise reduction was significant
