Exoracing AN10 Turbo Oil Drain Flange Kit

<div class="pdp-buying-guide"> <h2>Choose The Right Exoracing AN10 Turbo Oil Drain Flange Kit</h2> <p>AN10 turbo oil-drain flange for 40mm or 51mm bolt centres.</p> <ul> <li>Choose 40mm or 51mm turbo oil-drain bolt centres</li> <li>T6061 billet aluminium flange threaded for an AN10 oil-drain fitting</li> <li>Includes gasket and two M8x1.25x20 bolts; AN10 line fittings are sold separately</li> </ul> </div> <h2>Why Use An Exoracing AN10 Turbo Oil Drain Flange?</h2> <p>A turbo oil drain needs to move oil away from the turbocharger reliably. If the flange is the wrong size, the gasket does not seal, or the drain line is poorly matched, the result can be oil leaks, smoking, poor drainage or messy rework once the turbo system is already installed.</p> <p>This Exoracing AN10 drain flange gives you a clean way to build an AN10 turbo oil return setup. The billet aluminium flange is thick enough to resist distortion, the centre is threaded for an AN10 fitting, and the kit includes the gasket and M8 mounting bolts, so you are not hunting for basic hardware during the install.</p> <p>This is a smart part to replace while the turbo, manifold or downpipe area is already apart. If you are refreshing the drain side, it is also worth checking the related <a href="../../../../exoracing-turbo-oil-feed-and-drain-gaskets/">Exoracing turbo oil feed and drain gaskets</a>, <a href="../../../../exoracing-an10-turbo-oil-return-drain-fitting-stainless-steel/">Exoracing AN10 turbo oil return drain fitting</a> and nearby heat protection such as the <a href="../../../../exoracing-turbo-blanket-v3/">Exoracing turbo blanket</a> or <a href="../../../../exoracing-titanium-or-carbon-exhaust-wrap/">Exoracing exhaust wrap</a>.</p> <h2>Which Bolt-Hole Centre Should I Choose?</h2> <p>Measure from the centre of one oil-drain mounting hole to the centre of the other mounting hole on your turbocharger. Do not measure from the outside edge of the holes, as this can give the wrong result.</p> <table> <tbody> <tr> <td><strong>Option</strong></td> <td><strong>Choose This If</strong></td> <td><strong>Check Before Ordering</strong></td> </tr> <tr> <td>40mm bolt-hole centres</td> <td>Your turbo oil drain mounting holes measure 40mm centre to centre.</td> <td>Confirm the bolt spacing and that your drain fitting is AN10.</td> </tr> <tr> <td>51mm bolt-hole centres</td> <td>Your turbo oil drain mounting holes measure 51mm centre to centre.</td> <td>Confirm the bolt spacing and turbo drain face clearance.</td> </tr> </tbody> </table> <h2>Purchase Includes:</h2> <ul> <li>1 x Exoracing AN10 turbo oil drain flange</li> <li>1 x Exoracing turbo oil drain gasket</li> <li>2 x Exoracing cap head M8x1.25x20 bolts</li> <li>1 x Exoracing lifetime warranty</li> </ul> <h2>Features:</h2> <ul> <li>CNC machined from T6061 billet aluminium</li> <li>Centre hole threaded for AN10 oil drain fittings</li> <li>Available in 40mm or 51mm bolt-hole centre options</li> <li>8.5mm base thickness helps reduce the risk of flange distortion</li> <li>Includes oil drain gasket and M8 mounting bolts</li> <li>Useful for many GT25, GT28, GT30 and GT35 style turbocharger setups when the bolt spacing matches</li> <li>Designed to help build a clean, serviceable turbo oil return system</li> <li>Includes Exoracing lifetime warranty</li> </ul> <h2>Exoracing AN10 Turbo Oil Drain Flange Installation Guide:</h2> <p>Oil drain fitment matters because the return side of the turbo needs a clear, reliable path back to the sump or oil return point.

Measure the centre-to-centre distance between the two drain mounting holes on your turbo and choose either the 40mm or 51mm option.</p> <h3>Does the kit include a gasket and bolts?</h3> <p>Yes. The kit includes the AN10 oil drain flange, oil drain gasket and 2 x M8x1.25x20 cap head bolts.</p> <h3>Does this include the AN10 return fitting?</h3> <p>This listing includes the drain flange kit, gasket and bolts. If you need a matching fitting for your oil return line, see the <a href="../../../../exoracing-an10-turbo-oil-return-drain-fitting-stainless-steel/">Exoracing AN10 turbo oil return drain fitting</a>.</p> <h3>Which turbos does it commonly suit?</h3> <p>It is commonly used on many aftermarket GT25, GT28, GT30 and GT35 style turbocharger setups, but you must measure your turbo oil drain bolt spacing before ordering.</p> <h3>Why is the oil drain route important?</h3> <p>The turbo oil drain should flow smoothly back to the sump or return point. Avoid kinks, tight bends or uphill sections because poor drainage can cause oil leaks or smoke.</p> <h2>Notes:</h2> <ul> <li>Measure your turbocharger oil drain bolt-hole centres before ordering.</li> <li>Choose the 40mm or 51mm option to match your turbocharger.</li> <li>Professional installation is recommended.</li> <li>Recheck the drain flange for leaks after the first few heat cycles.</li> </ul> <div class="exo-v2-related-source-grid"> <div class="exo-v2-related-source-card is-current" data-product-id="383"><img src="https://cdn11.bigcommerce.com/s-2qhgaelfmo/products/383/images/84920/exoracing-oil-drain-adapter-an10-small__06536.1778775699.386.513.JPG?c=2" alt="Exoracing AN10 turbo oil drain flange kit contents" width="386" height="513" /> <span class="exo-v2-related-source-eyebrow">Turbo oil system</span> <h3 class="exo-v2-related-source-title">Exoracing AN10 Turbo Oil Drain Flange Kit</h3> <p class="exo-v2-related-source-text">AN10 turbo oil-drain flange for 40mm or 51mm bolt centres</p> <a href="#exo-v2-buy">Choose this product</a></div> <div class="exo-v2-related-source-card" data-product-id="936"><img src="https://cdn11.bigcommerce.com/s-2qhgaelfmo/products/936/images/61220/Exoracing-AN10-Universal-Turbo-Steel-sump-Return-no-weld__08422.1729182556.386.513.JPG?c=2" alt="Exoracing An10 Turbo Oil Return Drain Fitting Stainless Steel" width="386" height="513" /> <span class="exo-v2-related-source-eyebrow">Turbo oil system</span> <h3 class="exo-v2-related-source-title">Exoracing An10 Turbo Oil Return Drain Fitting Stainless Steel</h3> <p class="exo-v2-related-source-text">The AN10 bulkhead fitting creates the matching return port at a compatible steel sump or tank.</p> <a href="../../../../exoracing-an10-turbo-oil-return-drain-fitting-stainless-steel/">View product</a></div> <div class="exo-v2-related-source-card" data-product-id="785"><img src="https://cdn11.bigcommerce.com/s-2qhgaelfmo/products/785/images/60988/210_Series_AN06_AN08_AN10_AN12_AN16_Nylon_Black_Braided_Hose_1_EXO__94262.1729182561.386.513.jpg?c=2" alt="Exoracing Black Nylon Braided Hose 1.0m" width="386" height="513" /> <span class="exo-v2-related-source-eyebrow">Braided AN hose</span> <h3 class="exo-v2-related-source-title">Exoracing AN Black Nylon Braided Hose 1.0m</h3> <p class="exo-v2-related-source-text">Select the AN10 variant of the rubber-centred braided hose; the observed mixed-size basket is a warning not to copy a mismatched variant.</p> <a href="../../../../exoracing-an-black-nylon-braided-hose-1-0m/">View product</a></div> <div class="exo-v2-related-source-card" data-product-id="4954"><img src="https://cdn11.bigcommerce.com/s-2qhgaelfmo/products/4954/images/84955/SWHE-S-10-BLK_1__12998.1712759604.386.513.jpg?c=2" alt="AN Swivel Seal Hose End Fitting AN04-AN20" width="386" height="513" /> <span class="exo-v2-related-source-eyebrow">Matching hose end</span> <h3 class="exo-v2-related-source-title">AN Swivel Seal Hose End Fitting AN04-AN20</h3> <p class="exo-v2-related-source-text">Use AN10 swivel-seal hose ends to terminate the AN10 rubber-centred hose; PTFE and push-lock ends are not interchangeable.</p> <a href="../../../../an-swivel-seal-hose-end-fitting-an04-an20/">View product</a></div> </div>
