1375146300 Toyota LIFTER, VALVE, Price: 9.98$, Weight: 0.03kg

Engine Valve Lifter (Bucket Tappet) ⚙️

This precision cam follower sits between the cam lobe and the valve stem, controlling valve clearance and guiding smooth opening and closing. Built from hardened steel with a mirror-finished face, it keeps a stable oil film, reduces friction, and protects the camshaft at high RPM. Ideal for engines using bucket-over-valve layouts.

Why this part is needed

Correct lash is vital for power, quiet running, emissions, and long valve train life. Replacing a worn lifter restores timing accuracy, removes ticking, and helps maintain compression. Essential during head rebuilds, cam replacement, or when lash is out of spec.

How it works

The solid bucket rides in its bore while the cam lobe presses the crown. Its exact height sets lash (shimless design or used with a separate shim). Engine oil lubricates the contact and promotes gentle rotation to spread wear. Precision grinding keeps lift and duration true to the cam profile.

What happens if it’s damaged ❗

Symptoms include cold-start ticking, rough idle, misfire, loss of power, and poor fuel economy. Excessive clearance hammers the lobe; too-tight clearance overheats and burns valves. Severe wear can wipe a cam, cause metal debris, catalytic converter damage, or even a dropped valve.

Build & fitment details

CNC-ground, heat-treated, and often nitrided/DLC-coated for anti-scuff protection. Designed for DOHC heads using bucket tappets. Select the correct graded height to achieve factory lash specs.

Installation tips

Measure with feeler gauges on a cold engine, record each position, and match buckets per cylinder. Use assembly lube, keep buckets clean and in order, and torque cam caps in sequence. Replace heavily scored cams and ensure clean oil supply for long life.
