Mann & Hummel Provent 200 Installed (almost).
Finally, I have installed the Man & Hummel Provent 200 I purchased 6 months ago. I made up a bracket to locate it at the front right corner of the engine. This allowed me to run the vent hoses ( 25mm / 1 inch) from the factory PCV to the Catch Can. Used silicone rubber hoses and stainless steel Norma Cobra Clamps which I hope will never need further attention.
The Original PCV line to the Turbo Inlet is a trap for young players. One end is 1" the other end is 3/4", something I discovered after I ordered all the parts I thought I needed. Bugger!!
The Parts used were:
1. Mann & Hummel Provent 200 ( See attached PDF )
2. 1.5 metres of 1" (25mm) Silicone AeroFlow Hose
3. 0.5 metres of 3/4" (19mm) Silicone AeroFlow Hose
4. 3x 1" Silicone 90 degree elbows
5. 4 x male - male aluminium hose coupler ( Aluminium tube )
6. 1 x 1" to 3/4" reducer ( Plastic)
7. 12 x Norma Cobra Clips C34/9 Stainless Hose Clamps.
8. 2 x Norma Cobra Clips C30/8 Stainless Hose Clamps
9. 4 x 1/2' hose clamps
10. Mann & Hummel oil drain check valve to allow opil to be returned to the sump at a point above the oil level.
11. 1 metre of 1/2" heater hose ( for drain line )
12. M18x1.0 Hex Headed Plug - Replaces VW Allen Plug (same size) covering crank shaft locking hole in sump ( see notes below)
13. Hose barb 1/2" (12mm) to attache to Item 12 to allow oil return ( see notes below )
14. Mann & Hummel 1/2" x 1/2" non-return valve
Additional Items Required.
1. Various Cable Ties
2. DIY Mounting bracket for affixing Catch Can. ( see my photos )
Mounting Bracket:
I fabricated from mild steel a bracket running as about 45 degrees from the right hand bonnet/hood gas strut mount point to the front radiator support panel. I used nutserts ( pop rivet style nuts ) and a little welding to make mine. By using two fixing points on the strut mount and one on the radiator support, I was able to eliminate nearly all flex, resulting in a robust mount. Have a look at the photos as they show it in some detail.
Oil Return Path , still to be completed
Prompted by a suggestion from Dragline1570 ( Thank you Mark ) is to utilise the access plug used for locking the crankshaft during timing chain servicing. This plug is an Allen type round headed plu located in the upper half cast section of the sump. By replacing this with a Hex Headed Plug/Bung, I will be able to drill and tap a suitable hole in the centre of the new plug and then attach a hose barb to accommodate the 1/2 oil drain line. Returning the oil condensate to the sump is a recommended solution by Mann & Hummel, however you must install a non-return valve in the drain hose if the return point is above the oil level. Without the non-return valve you will pressurize the Catch Can with air from the crank case. Not a good thing to do. This solution also allows removal without leaving a footprint.
Hex Plug For Oil Return
Hex Bung to allow drilling and taping.
