Main Bearing Housing Bore Caution For 1993- 2002 Ford/Mazda 2.5L VIN B & KL Engines
The AERA Technical Committee says there may be some confusion about how to properly determine the main bearing bore diameter on 1993-2002 Ford 2.5L VIN B and KL engines. This engine is made by Mazda and used in the Probe and 626 car models. It appears some previously published information may have been inaccurate. Many service specifications have listed a housing bore diameter .002˝ smaller than it should be.
If owners of ’02 CR-Vs are complaining of a creaking from the A-pillar when turning left, the problem may be the right front engine mount on the cam chain side. If the rubber in the mount is misadjusted or faulty, it can make a creaking, ticking, or spot-weld-like noise that seems to be coming from the base of the front passenger’s A-pillar.
On various vehicles when servicing the head gasket on certain Ford remanufactured engines, it is critical to determine the type of remanufactured engine that is being serviced, in order to identify the correct replacement gasket.
All 1999 Protege (1.6L) with VINs lower than JM1 BJ222* X0 140057.
All 1999 – 2000 Miata with (1.8L) VINs lower than JM1 NB353* Y0 155947.
DESCRIPTION A rattling noise may be heard from the engine when depressing the clutch or when revving the engine in neutral. In extreme cases, customers may experience noise at all times. This concern can be caused by improperly machined number 4 main cap of cylinder blocks which may result in premature wear of the thrust bearing. Customers having this concern should have their vehicle repaired using the following procedure.
A strange noise may cause concern to owners of some Chrysler vehicles, particularly 2001-2004 vehicles equipped with a 2.0L, 2.4L DOHC or 2.4L Turbo engine. The noise may occur when the vehicle is in park, and the engine is running between idle and 1,400 rpm at normal operating temperature. The sound is heard at the upper end of the engine (cylinder head) toward the right front side (passenger side), and is irregular, not periodic or harmonious. The frequency of the noise will increase with rpm. The sound is more of a high-pitched “snapping” noise than a low metallic knock. If the customer describes the noise and the installer determines that the sound is coming from the described location, the repair procedure involves chamfering the bore radius on cam bearing caps L2 through L5 and R2 through R5. Before beginning the repair, review safety procedures in ALL-DATA Repair.
This tachometer is factory calibrated for 8 cylinder engines. For operation on 4 or 6 cylinder engines, a switch adjustment must be made.
1. Remove cup by placing the tachometer face down on a smooth surface. Remove the phillips screw on the back and gently lift the cup off to expose the circuit board. Take care
not to pull on the wires.
2. Locate the switch on the circuit board. Move each of the two switches to the proper cylinder selection according to the diagram illustration on the right.
4 Cyl.- Both switches down
6 Cyl.- Switch #1 down. Switch #2 up
8 Cyl.- Both switches up
3.Replace the case on the tach with mounting bracket at the bottom (make sure the wires are clear of the screw hole).
4. Replace the screw
