| SUBJECT: | Oil Seepage Diagnosis and Repair Procedures |
INTRODUCTION
The purpose of this Bulletin is to provide procedures for the diagnosis and repair of oil seepage which may be coming from the areas listed below:
There are six areas that should be closely inspected if an oil leak is reported by the customer:
1. The 6mm tapped hole casting boss area in the left-hand camshaft cap
2. The sealing surfaces between the camshaft carrier and cylinder head
3. The sealing surface between the cylinder block and the upper oil pan
4. The sealing surfaces of the front timing chain cover
5. The sealing surfaces between either the left or right-hand camshaft cap and/or camshaft carrier
6. The sealing surfaces between the cylinder head block-off plate (on M/T models) or the vacuum pump assembly (on A/T models)
Note: Refer to the April 2011 issue of TIPS for more information on Fluid Leak Detection.
If oil seepage is verified coming from the 6mm threaded hole in the left-hand camshaft cap, install the specified bolt and flat washer.
Bolt: Part# 800206180
Washer: Part# 031106000
Tightening Torque: 6.4 +/- 0.5 Nm (57 +/- 4 inch-pounds)
If oil seepage is verified coming from between the cam carrier and the cylinder head as shown in the photos below, remove the cam carrier. Clean the machined sealing surfaces thoroughly and then re-seal using Liquid Gasket ThreeBond 1217H (SOA868V9610
) or equivalent*. As shown in the photos below, the o-rings between the cam carrier and the cylinder head will need to be replaced as they are not re-usable. This would also be a good time to clean the Active Valve Control System (AVCS) filter screens which are contained in the cam carriers and shown in the photos below. NOTE: The filter screens are one-time use and must be replaced if they need to be removed. The replacement filter part # is 14451AA050.
One-time use cam carrier o-rings which must be replaced. AVCS filter screens must be replaced if removed.
If you find oil seepage between the cylinder block and upper oil pan, remove the upper oil pan, clean the machined sealing surfaces thoroughly and then re-seal using Liquid Gasket ThreeBond 1217H (SOA868V9610) or equivalent*. In addition, the o-rings between the upper oil pan and the cylinder block along with those between the upper and lower oil pan will need to be replaced as they are also one-time use items.
IMPORTANT: The oil level switch o-ring is a one time use part and should be replaced when the switch is removed, replaced, or when the upper oil pan is resealed.
NOTE: Only reseal the front chain cover AFTER confirming there is no oil seepage coming from the either cam retainer cap (area 1) and / or the cam carrier (area 2) as previously described.
1. If there are no oil droplets found on the engine under-cover or the lower radiator hose, thoroughly clean the chain cover sealing area along with the surrounding cylinder head and crankcase areas. Re-check for oil seepage again at the next service interval.
2. If the front chain cover is leaking and needs to be resealed, follow the repair procedure in the applicable Service Manual. Thoroughly clean and inspect the sealing surfaces then re-seal using Liquid Gasket ThreeBond 1217H (SOA868V9610) or equivalent*.
If oil seepage is verified coming from the front camshaft cap and/or camshaft carrier as shown in the photos below, remove the cam cap and clean both surfaces thoroughly before applying sealer. Note: The 2 o-rings between the camshaft cap and the cam carrier will need to be replaced as they are not re-usable.
Apply Liquid Gasket, ThreeBond 1217H (SOA868V9610) or equivalent* as shown below:
If oil seepage is verified at the bottom of the cylinder head block-off plate (on M/T models) or bottom of the vacuum pump assembly (on A/T models), the source may be the area between the cam carrier and the intake cam cap. The seeped oil then collects at the bottom of the block-off plate or vacuum pump as shown in the photo and illustration below.
IMPORTANT: ALWAYS replace the small vacuum pump o-ring as it is a one-time use item.
Remove the cylinder head block-off plate (or vacuum pump) following the procedure outlined in the applicable Service Manual and thoroughly clean all the machined sealing surfaces. Be sure to trim away any sealant which may have squeezed out during installation of the intake cam cap onto the cam carrier. Apply ThreeBond 1217H (SOA868V9610) sealant as shown in the reference illustrations below.
