Product overview
VW Engine Support
The engine support carrying reference 8D0 399 114S sits in the VW Parts section of the RUIFAN catalogue. RUIFAN has manufactured parts of this type in Ruian, Zhejiang since 1994.
It is available to distributors, rebuilders, workshops and private-label programmes on the same terms as the rest of the catalogue.
An engine support carries the weight of the powertrain and reacts torque into the body structure. Castings of this type fail by fatigue rather than impact, so a crack often appears with no obvious cause and the part has to be replaced rather than repaired. The archived record for this reference holds the catalogue name, the vehicle brand block and the photograph; nothing further was stored, and nothing further is claimed here.
What this reference is used for
- Aftermarket catalogue coverage of mount references
- Replacement of a fatigued or cracked mount casting
- Supply alongside the oil pan for the same application
- Workshop and fleet service stock

Who it is for
Buyers Who Order This Reference
Importers and private label brands
Brand owners who sell under their own label and need the factory behind that label to stay the same from season to season.
OE and tier programme buyers
Engineering buyers who arrive with a drawing or a sample instead of a catalogue number.
Classic and long tail specialists
Single-marque and restoration businesses that keep selling references mainstream catalogues have already dropped.
Problems it solves
What Brings Buyers to This Part
- The support is being replaced at the same time as the pan and the buyer does not want a second supplier and a second freight event.
- Mount castings crack from fatigue rather than impact, so the failure appears without an obvious cause and the part has to be sourced quickly.
- The support reference is hard to find because it sits in a component group most pan suppliers do not stock.
- A workshop order for a pan arrives without the bracket that has to come off with it.

Scheduled against a stated annual oil pan output of 500,000 pieces
Long-tail references consolidated with volume lines instead of being dropped
No invented specifications: anything the archive did not record is shown as not recorded
Supplied against the reference recorded in the catalogue, not against a guessed equivalent
Materials and manufacturing
How This Engine Support Is Produced
The archived record does not state a material for this reference. RUIFAN produces both drawn steel and cast aluminum parts of this type, and the correct construction is confirmed against the part being replaced before production is scheduled.
Confirm construction
Material and method confirmed against the part being replaced or a supplied sample.
Form or cast
Drawn from sheet, or die, gravity or sand cast, according to what the original part is.
Machine and finish
Sealing faces, bores and threads finished to the reference.
Inspect and pack
Checked against the reference sample, then packed with the sealing face protected.
Manufacturing methods listed here are the ones recorded on the original RUIFAN services page: deep and shallow draw stamping; die casting, sand casting and gravity casting; chrome plating and vacuum metallization. The method used for a given reference is confirmed against the part being replaced.
Quality control
Quality Systems Behind This Reference
RUIFAN recorded ISO 9001 and TS 16949 quality systems on its original site. Certificate numbers and validity dates were not stored in the archived material and are supplied on request rather than stated here.
Sealing flange
Flatness across the full perimeter decides whether the part seals at all. It is the first thing to check on arrival.
Drain boss
Thread condition and squareness to the boss face, checked before packing.
Dimensional check
Against the reference sample for the catalogue number being run.
Packing
Flange protection specified per programme, because a bent flange makes a sound part unusable.
Customisation
If This Reference Is Not Exactly What You Need
The original RUIFAN site stated that the factory develops oil pans and other aluminum castings from customer-supplied samples or drawings. That route covers references that never made it into the catalogue, superseded parts whose tooling has been scrapped, and private-label variants of an existing part.
A physical sample is enough to start. Where no sample survives, a dimensioned drawing or a 3D file works. Tooling cost, lead time and ownership are agreed in writing before any work begins.
What to send with an enquiry
- The number stamped or cast into the part being replaced
- The vehicle, the engine code and the production year
- A photograph of the flange face and one of the drain boss side
- Annual quantity, or the quantity for a first order
- Destination market, which affects packing and documentation
Comparison
8D0 399 114S Against the Alternatives
How sourcing this reference from RUIFAN compares with the other routes a buyer has.
| Option | What you get | Where it falls short |
|---|---|---|
| RUIFAN catalogue supply | The reference held in a 136-number catalogue with the archive data published alongside it, produced in one plant with one packing standard. | Fields the original database never recorded are shown as not recorded rather than filled in. |
| Original equipment channel | Guaranteed fitment and full manufacturer documentation. | Highest unit cost, and older references are progressively withdrawn from supply. |
| Local pattern part supply | Short lead time and no import handling. | Coverage is usually limited to fast movers, so the long tail of a number family stays unsourced. |
| Used or reclaimed engine support | Lowest purchase cost, sometimes the only route for a withdrawn reference. | Flange flatness, thread condition and corrosion are unknown until it is on the bench. |
Use guide
Identifying and Fitting 8D0 399 114S
A working sequence for confirming the reference and fitting it without a repeat leak.
- Confirm the reference against the number cast into the support being replaced.
- Check bore positions and section thickness against the old part before the engine is lowered.
- Support the engine independently before removing the old mount.
- Fit new fasteners where the manufacturer specifies single-use bolts.
- Torque to the vehicle manufacturer's figure with the engine at its normal resting position, not while it is jacked.
Torque figures, sealant specification and gasket type are set by the vehicle manufacturer for the engine concerned. Follow that procedure rather than a generic figure.
Questions About 8D0 399 114S
What vehicle does 8D0 399 114S fit?
The archived catalogue record lists this reference in the VW Parts block. No vehicle application table was stored for this reference in the original database, so none is shown. Send the vehicle, the engine code and the number from the old part and we will confirm against the catalogue before quoting.
Do you have cross reference numbers for this part?
No alternate numbers were stored against this reference in the original database, so none are published here. Twenty of the 136 catalogue records do carry recorded alternates. If you hold a number you believe matches this part, send it with a photograph and we will check.
What is 8D0 399 114S made from?
The original catalogue record did not state a material for this reference, so none is published. RUIFAN produces both drawn steel and cast aluminum parts of this type, and the correct construction is confirmed against a sample or the part being replaced before quoting.
Can you supply this reference together with other VW lines?
Yes. The VW Parts block holds 52 references and they are normally quoted and shipped together. Consolidating is what makes low-volume lines viable in the first place.
What if the number I need is not in your catalogue?
The original RUIFAN site stated that the factory develops oil pans and other aluminum castings from customer-supplied samples or drawings. Send a sample, a drawing or a dimensioned photograph and we will review whether it can be tooled.
