Package Contents

1 complete engine overhaul gasket kit as shown in the product images, including the cylinder head gasket and assorted upper/lower gaskets and seals supplied in the actual kit.
Pistons, piston rings, liners, bearings, pumps, injectors, head bolts and other hard engine parts are not included.
Materials and individual pieces can vary by gasket position and production batch.

Check Before Ordering

Match the original or reference part number when available.
Confirm the complete engine model, suffix and serial number from the data plate.
Compare the head-gasket shape, cylinder bore openings, bolt holes, oil/water passages and every included piece with the product images.
Not for 24-valve ISB common-rail engines. Verify engine data plate, serial range, piston/head configuration and gasket layout.

Installation and Warranty

Professional installation is required. Dry-fit and inspect every gasket before assembly. The 3-month limited warranty covers confirmed manufacturing defects. Normal installation or use does not, by itself, cancel the right to submit a manufacturing-defect claim. Damage caused by incorrect fitment, improper installation, misuse, or engine condition is not covered.

XAVORNIK is an independent replacement-parts brand and is not affiliated with the referenced equipment or engine manufacturers. Manufacturer names and part numbers are used only to identify compatibility.

Installation & return notice

This product is covered by a 3-month limited warranty from the date of delivery for confirmed manufacturing defects.

Installed, contaminated, damaged or incomplete gasket sets are not returnable unless a manufacturing defect is confirmed.

Damage or incompatibility caused by an incorrect engine model, engine version or serial number, incorrect gasket selection, improper surface preparation, incorrect torque or tightening sequence, reuse, overheating, lubrication or cooling-system failure, contamination, chemical sealants or incorrect assembly is not covered.
