Chevrolet P10 Van Engine Camshaft Thrust Plates

Chevrolet P10 Van Engine camshaft thrust plates

Starting at $12.95, AutoBuffy stocks 2 engine camshaft thrust plates from Cloyes. The thrust plate bolts to the engine block and controls fore-aft camshaft movement, keeping it positioned correctly relative to the timing components. When it wears or cracks, camshaft endplay increases, causing timing instability, oil leaks, and accelerated bearing damage.

Signs your Chevrolet P10 Van needs a new engine camshaft thrust plate

  • Excessive camshaft endplay measured beyond manufacturer tolerance during a cam bearing inspection
  • Rhythmic ticking or knocking from the front of the engine that changes with RPM, indicating the cam is walking forward and backward
  • Oil seeping from the front of the block near the timing cover, caused by a cracked or worn thrust plate no longer sealing endplay
  • Erratic or unstable ignition timing that cannot be corrected through normal distributor adjustment, pointing to cam position shift
  • Unusual wear patterns on timing chain, gears, or belt drive components from the camshaft moving axially under load
  • Engine runs rough or misfires at idle when camshaft position shifts enough to disturb valve timing events

Which engine camshaft thrust plate should you buy for your Chevrolet P10 Van?

The main decision is matching material grade and thickness spec to your engine's original design, since thrust plates are precision parts where even small dimensional differences affect camshaft endplay. OE-replacement plates restore factory clearances, while performance options use harder alloys for high-RPM or high-lift camshaft applications. Always verify the plate is application-specific — a universal part will rarely provide the correct endplay.

OE-Replacement Steel
Best for
Daily drivers and stock engine rebuilds
What you get
Factory-matched dimensions and material; restores correct endplay with no modification required
Performance Billet Steel
Best for
Modified engines, aggressive cams, or high-RPM builds
What you get
Harder alloy resists wear under increased valve spring pressure and higher sustained RPM
Double-Groove / Dual-Tab Design
Best for
Engines with known single-plate wear history or extended rebuild intervals
What you get
Added surface area distributes thrust load across more material, extending service life
Complete Kit (Plate + Bolts + Gasket)
Best for
Full engine rebuilds or timing component replacements
What you get
Everything needed for a clean install; eliminates the risk of reusing stretched bolts or a compromised gasket

Replacing the engine camshaft thrust plate on a Chevrolet P10 Van

Advanced⏱ 3–6 hoursSocket set and torque wrenchHarmonic balancer pullerDial indicator with magnetic baseGasket scraper and engine-safe solventThread locker (for thrust plate bolts)

Replacing the camshaft thrust plate requires removing the timing cover and, depending on the engine layout, the harmonic balancer, timing chain or gears, and sometimes the camshaft itself. Once the plate is accessible, remove the retaining bolts, swap in the new plate, and torque the fasteners to specification using thread locker where recommended. Before final assembly, verify camshaft endplay with a dial indicator to confirm it falls within the acceptable range.

Frequently asked questions

How much does it cost to replace engine camshaft thrust plates on a Chevrolet P10 Van?
The part itself starts at $12.95 for a Chevrolet P10 Van. Total replacement cost depends heavily on how much engine disassembly is required to reach the timing cover. On many engines this job is bundled with a timing chain or camshaft replacement, which spreads labor costs. DIY saves the most if you are already opening the front of the engine.
What causes a camshaft thrust plate to wear out on a Chevrolet P10 Van?
Thrust plates wear primarily from metal-to-metal contact as the camshaft exerts forward and rearward force during normal operation. Low oil pressure, infrequent oil changes, and extended idling accelerate wear by reducing the lubricating film between the plate and cam journal. High-performance camshafts with aggressive profiles impose greater axial loads and shorten plate life further.
Can I drive my Chevrolet P10 Van with a worn or broken camshaft thrust plate?
Driving with a failed thrust plate is not recommended. Excess camshaft endplay disrupts valve timing, stresses the timing chain or gears, and can cause the cam to contact surrounding components. Continued operation risks scoring the camshaft journals and block, turning a straightforward parts replacement into a much more expensive engine repair.
How do I measure camshaft endplay to know if the thrust plate is bad on a Chevrolet P10 Van?
Mount a dial indicator against the front of the camshaft snout, then carefully pry the cam fore and aft. The total movement recorded is endplay. Compare the reading to your engine's published specification range. A reading above the maximum allowable limit confirms the thrust plate is worn beyond service tolerance and must be replaced before reassembly.
Should I replace the camshaft thrust plate when replacing the camshaft on a Chevrolet P10 Van?
Yes — replacing the thrust plate during any camshaft replacement is standard practice. The plate is inexpensive relative to labor already performed, and a worn plate on a new camshaft will cause premature cam wear and incorrect endplay from day one. Replacing both together ensures a clean baseline and avoids reopening the engine shortly after.
How many engine camshaft thrust plate options are available for my Chevrolet P10 Van?
AutoBuffy currently stocks 2 camshaft thrust plates for the Chevrolet P10 Van year range 1973, sourced from Cloyes. Use the vehicle selector at the top of the page to filter results to your exact engine code, since some P10 Van applications use different block configurations that require a specific plate thickness or bolt pattern.
