OEM 168805000018A – The genuine SANY parts Cylinder Head Cover Gasket (also known as valve cover gasket) is engineered to seal the cylinder head cover on SANY heavy‑duty diesel engines. With reference 168805000018A, this elastomeric gasket prevents oil leaks from the top end, maintaining proper lubrication pressure and preventing contamination. Manufactured from high‑temperature ACM rubber (acrylic) with a steel carrier, the 168805000018A gasket resists 150°C continuous oil exposure and seals against blow‑by gases. It is a direct fit for Actlon tippers, SY mining trucks, and concrete mixers powered by SANY D09, D12, and D13 engines. Trust the authentic 168805000018A component to eliminate messy oil seepage and avoid engine bay fires.

168805000018A Cylinder Head Cover Gasket – Precision Sealing for SANY Diesel Power
The cylinder head cover gasket with OEM number 168805000018A is a direct replacement for SANY D09, D12, and D13 engines found in Actlon trucks, SY mining dumpers, and concrete pump trucks. This gasket features a molded rubber‑to‑metal construction where the elastomer is bonded to a rigid steel core. This design prevents extrusion under high crankcase pressures (up to 0.5 bar) and maintains a consistent seal through thermal expansion cycles. The 168805000018A gasket also incorporates oil drain back holes and bolt hole locators for error‑free installation.
Every genuine 168805000018A gasket is 100% inspected for flash, porosity, and hardness (60–70 Shore A). The material is specially formulated to resist diesel, engine oil, coolant, and ozone. Unlike cork or paper gaskets that shrink and crack, the ACM rubber compound maintains its flexibility for over 10,000 hours of operation. Using 168805000018A eliminates oil mist accumulation on the engine exterior, reducing the risk of fire and making leak detection easier.
The gasket’s design matches the exact sealing bead geometry of the SANY cylinder head cover, ensuring even compression around all bolts. This prevents warping of the cover and avoids over‑compression that can split inferior gaskets.
Oil‑Tight Seal
ACM rubber compound resists engine oil, diesel, and additives; zero weepage guaranteed.
High Heat Resistance
Continuous operation at 150°C, peak spikes up to 180°C without hardening.
Permanent Flexibility
Low compression set (<20%) ensures the gasket springs back after thermal cycles.
Precision Fit
Steel carrier maintains shape during shipping and installation; molded bolt hole locators.

Why Genuine 168805000018A Outperforms Aftermarket Valve Cover Gaskets
Aftermarket cylinder head cover gaskets often use inferior nitrile rubber (NBR) or silicone that cannot withstand the high heat of turbocharged diesel engines. NBR hardens after 500 hours, causing leaks and requiring re‑torquing. The genuine 168805000018A uses ACM (polyacrylate) rubber, which retains flexibility at 150°C and resists sulfur‑rich diesel oils. This translates to a service life of over 10,000 hours – more than double that of typical aftermarket parts.
Steel carrier integration is another critical advantage. The steel core in 168805000018A prevents the gasket from being over‑compressed during assembly, a common cause of gasket splitting in one‑piece rubber gaskets. The carrier also provides dimensional stability, ensuring the rubber bead aligns perfectly with the cover’s sealing groove. SANY’s original gasket also features molded rubber grommets at bolt holes that act as torque limiters – they bottom out when correct compression is reached, preventing damage.
Using a genuine 168805000018A gasket also maintains engine breathing integrity. A leaking valve cover allows unfiltered air into the engine via the PCV system, leading to dust ingestion and accelerated wear. The tight seal also prevents oil mist from soaking electrical sensors and wiring harnesses, avoiding false diagnostic codes.

Installation Guide for Cylinder Head Cover Gasket 168805000018A
Before installing the 168805000018A gasket, thoroughly clean the cylinder head cover mating surface and the cylinder head mounting surface. Remove all old gasket residue, oil, and dirt. Inspect the cover for cracks or warpage using a straightedge; warpage greater than 0.3 mm per 300 mm requires cover replacement. Do not use any additional sealant – the integrated rubber beads provide a perfect seal when the cover is properly torqued.
Position the 168805000018A gasket onto the clean cylinder head surface using the locating dowels. Then install the cylinder head cover, ensuring all bolt holes align. Tighten the cover bolts in two stages using a star pattern. Stage 1: 5 Nm (finger tight). Stage 2: torque to 12 Nm ± 1 Nm. Do not exceed 15 Nm, as this may damage the rubber grommet limiters. After the engine has run for 30 minutes and reached operating temperature, re‑torque the bolts to 12 Nm. Always replace the gasket whenever the cylinder head cover is removed – never reuse an old 168805000018A gasket, as the rubber takes a permanent set after compression.
