294-1827 C6.4 Oil Filter Seat: Verify the Engine Group and Port Layout
2026/10/11
The site listing identifies 294-1827 as an oil filter seat for C6.4 applications on E320DL/E325D. It does not specify thread standards, port map, gasket details or engine serial break. Confirm these against the removed seat and the exact engine build before purchase.
Inspection checklist
- Record machine model, serial number and engine identification; the model family alone may not resolve production changes.
- Photograph the installed part number and casting marks before removal.
- Compare the old and offered parts: bolt pattern, sealing face, overall height, visible passage layout and attached fittings. Measure with a suitable tool; do not identify threads by eye.
- Ask whether the quote covers the seat only or also seals, bolts, fittings or an attached housing. Request written contents.
Choose the repair scope after inspection
| Scope | Condition | Commercial and downtime factors |
|---|---|---|
| Gasket/seal service | Seat is reusable and the leak is traced to a replaceable seal. | Lowest parts scope; diagnosis and access labor still determine downtime. |
| Seat replacement | Sealing face or body damage is confirmed and replacement dimensions match. | Part cost plus removal/cleaning/installation; confirm whether related seals and hardware are included. |
| Wider oil-system diagnosis | Leak, pressure or contamination symptoms are not isolated to the seat. | Additional checks and parts affect labor and downtime; changing the seat alone may not resolve the cause. |
Send label photos, engine serial details and clear views of the sealing face and ports to request a quote. Ask the supplier to list included seals and confirm fitment limits for 294-1827.
