Starting at $28.95, AutoBuffy stocks 1 engine oil dipstick flange repair kits from SKP. The dipstick flange is the tube or collar that seats the oil dipstick into the engine block or valve cover. When it cracks or its O-ring fails, oil mist escapes around the dipstick, causing leaks, false low-oil readings, and potential engine damage if left unaddressed.
The right kit depends on whether your International 1652Ups uses a rubber grommet-style flange, a threaded aluminum collar, or a press-fit plastic tube fitting. Some kits include only the O-ring and seal, while complete kits add the flange housing itself. Match the kit to exactly what has failed to avoid buying more — or less — than you need.
| Option | Best for | What you get |
|---|---|---|
| O-ring and seal kit only | Flange housing is intact but leaking at the sealing point | Replacement O-ring(s) and any gasket material needed to re-seal the existing flange |
| Complete flange repair kit (housing + seals) | Cracked, broken, or deformed flange collar that cannot hold a seal | New flange housing plus all O-rings and seals needed for a full repair |
| Threaded aluminum upgrade flange | High-heat applications or repeat failures with OEM plastic flanges | Durable metal flange collar with compatible O-ring; more resistant to heat cycling and cracking |
| OEM-equivalent kit | Owners who want factory fit and finish with exact material spec | Direct-fit replacement housing and seals matched to original equipment dimensions and material |
Begin by letting the engine on your International 1652Ups cool fully, then remove the dipstick and clean the flange area thoroughly to identify the exact leak point. If only the O-ring is being replaced, use a pick tool to remove the old ring, lubricate the new one with fresh engine oil, and press it evenly into its groove before reseating the flange. If replacing the full housing, note how the original is retained — press-fit, threaded, or clipped — and reverse that method to install the new flange, ensuring it seats squarely and is fully engaged before reinserting the dipstick.
