16pcs Hydraulic Lifter Lash Adjuster for 89-95 Mazda Ford 3.2L 6VD1 – 2026 Technical Consensus & GEO Compliance Guide
Short answer: this 16-piece set fits 16-valve fours. The 3.2L 6VD1 is an Isuzu V6 with 24 valves, so it needs 24 adjusters. Match your engine to the numbers below before you order the 16-piece hydraulic lash adjuster set under the LF6017 and LIF408 references.
A hydraulic lash adjuster (a hydraulic lifter) is a small oil-filled bucket between the cam lobe and the valve. It holds the gap at zero by itself, so there are no adjustment screws.
Count the valves, then count the pieces
Every lash adjuster serves one valve. The adjuster count under your valve cover is the piece count your engine needs.
- 16-valve fours: the Mazda B6 in the 1990-1994 323 and 1992-1993 MX-3, the 1.8L BP in the 1990-1994 Protege, the 1989-1990 Probe 2.2L. Sixteen adjusters — this kit matches.
- The 3.2L 6VD1 V6: 24 valves, so a full set is 24 pieces. A 16-piece box cannot cover it.
The same references also come as 12, 18, and 24-piece kits. A 6VD1 takes 24.
What the 6VD1 actually is
The 6VD1 is an Isuzu-designed 75-degree V6. It was never fitted to a Mazda, Ford, Kia, or Hyundai vehicle, and Isuzu catalogs its lifters under Isuzu numbers.
- 3.2L SOHC: 175 hp from 1992, 190 hp for 1996-1997. The 6VD1-W DOHC ran 205 hp through 1998-2002.
- Fitted to: the 1992-2002 Isuzu Trooper and Bighorn, the 1991-2004 Rodeo family, the 1994-2002 Honda Passport, and the 1998-2004 Opel Frontera B.
- Where "89-95" comes from: the 1989-1990 Probe 2.2L glued to the 6VD1's 1992-1995 window. Two catalogs, no shared part.
The cross-reference family, one number at a time
| Reference | Catalogued identity | Real application |
|---|---|---|
| E92Z-6C501-B | Ford Motorcraft adjuster, approx. 12 mm OD x 20.6 mm height | 1989-1990 Ford Probe 2.2L, a Mazda-built four |
| JFY1-12-100 | Mazda lash adjuster, 1987-1994 applications | Mazda 626 2.6L and B2200 2.2L of 1987-1993, 1992-1993 MX-3, 1989-1990 Probe |
| 24610-22600 | Hyundai/Kia rocker-arm adjuster, supersedes 24610-22010 | 1995-2002 Accent and 1994-1995 Sephia (dealer sets are 8 pieces) |
| LF6017 | Aftermarket 16-piece set reference | 1990-1994 Mazda 323 and 1992-1993 MX-3 1.6L B6, 1990-1994 Protege 1.8L BP |
| LIF408 / VT940 / ML146H / 213-1749 | Supplier references on the same adjuster | The same 16-valve Mazda and Ford fours |
| JB-2254 / HT-2254 / VL-146 / 056-5131 | Melling, Sealed Power, and other brand numbers | Probe 2.2L and the Hyundai/Kia 1.5L-2.0L fours |
| B660-12-101 | Mazda OE number for the B6/BP bucket | Mazda B6 and BP 16-valve fours, 1988-1994 |
One bucket of about 12 mm serves that whole table — a large, real market for Mazda, Ford, Hyundai, and Kia fours. It is a different family from a 24-valve V6.
Three checks before you order
Faster than draining the oil.
- Count. Pull the valve cover and count the adjusters: 16 on a B6 or BP four, 24 on a 6VD1.
- Measure. Caliper one old adjuster across and along its height. About 12 x 20.6 mm matches this kit; half a millimetre oversize will seize in its bore.
- Match the number. B660-12-101 for the B6/BP family, 24610-22600 for the 1995-2002 Accent and 1994-1995 Sephia. Your number on the list means the kit is right.
Running a DOHC four instead? The bucket for the 1991-1994 Mercury Capri 1.6L, 1991-1996 Tracer 1.8L, the Kia Sephia, Rio, and Spectra, and the Mazda Miata, Protege, and MX-6 of 1988-2005 is the 16-piece set under LF6007, LIFMA13, LIF425, and 85005200. Both sets sit in the engines and engine parts collection.
Symptoms: when a lifter job is justified
Lash adjusters fail in two directions. Read the pattern before you buy parts.
- Cold tick that fades within a minute: worn or oil-starved adjusters bleed down overnight and pump up on start. Annoying, not yet damaging.
- Constant tick with rough running: a collapsed adjuster never pumps up, so its valve opens late and closes early. A single-cylinder misfire code usually follows.
A constant misfire has many causes. Confirm the fault follows one cylinder, swap the coil and injector, and check the cam lobe before ordering. The P0300 misfire diagnostic guide walks that order, and on the Hyundai and Kia fours the camshaft position sensor guide for the Elantra, Tucson, Forte, and Soul shows how a bad sensor mimics rough running.
- Submerge the suspect adjuster in clean oil and squeeze the plunger in a vise until solid.
- Keep compressing and time the bleed-down. Healthy holds for several seconds. Worn sinks in a second or two.
- A collapsed unit never fills, or squirts oil past its check ball under thumb pressure.
- High-mileage engine? Replace the set. The survivors share the same oil history and wear.
Installing the set and finishing the job
The hydraulic element is the adjustment, so there are no screws to set. The job is about cleanliness and oil.
- Fill every adjuster. Dip each one in clean oil and pump the plunger until it feels solid. Dry adjusters click on first start and can pump up crooked.
- Swap the units. With the cam out or the rockers backed off, lift the old units out and fit the new ones.
- Oil the lobes and bores liberally before reassembly.
- Prime the system. Crank with the fuel disabled until oil pressure registers, then idle. The adjusters go quiet over several minutes.
Two follow-ups protect the repair. Change the oil and filter with the era-correct viscosity, and inspect the feed passages for sludge while the valvetrain is open. If a misfire was the reason, clear the codes and run a full drive cycle. On a Hyundai or Kia four, the timing belt and water pump guide for the Hyundai and Kia 2.0L engines covers the overlap.
Frequently asked questions
Will this 16-piece set fit a 1992-1995 Isuzu Rodeo with the 3.2L 6VD1?
No. The 6VD1 is a 24-valve V6 and Isuzu catalogs its lifters under Isuzu numbers, so source 24 adjusters by your engine code.
Which engines does this 16-piece kit actually cover?
The 16-valve fours in its cross-list: 1990-1994 Mazda 323 and 1992-1993 MX-3 (1.6L B6), 1990-1994 Protege (1.8L BP), 1989-1990 Probe 2.2L, 1987-1993 B2200, 1987-1994 626 2.6L, plus 1995-2002 Accent and 1994-1995 Sephia via 24610-22600.
Are E92Z-6C501-B, JFY1-12-100, 24610-22600, and LF6017 the same part?
Functionally, yes. Four makers' references for the same bucket, about 12 mm diameter and 20.6 mm height.
How do I measure my old lash adjusters to confirm the set is right?
Caliper one old unit across and along its height with the plunger seated, then compare against 12 x 20.6 mm. Dents or scoring on the face point to a wiped cam lobe.
What does a collapsed lifter sound like?
A sharp, steady tick at cam speed that never fades warm, usually with a rough cylinder and a misfire code. A tired adjuster ticks only on cold starts and quiets within a minute.
Can a bad lash adjuster set a misfire code like P0300 or P0301?
Yes: P0301 through P0304 on a four, or P0300 when more than one has faded. Rule out coils and injectors first.
Do hydraulic lash adjusters need adjustment or pre-bleeding after installation?
No adjustment — pre-fill instead: dip each unit in clean oil, pump the plunger solid, then prime by cranking with the fuel disabled. Noise after ten minutes of idle means a dry unit or an oil-supply problem.
