It would, however, be advisable to have a look at them, and as we are going to have another attempt with the transmission rattles, we will take the opportunity to dismantle the cylinder head. RE. YOUR SLIPPING CLUTCH. Our clutch slipped through oil getting on the front fabric. This did not again occur after we had cured the oil leak past the rear of the engine. We believe your trouble is due to this cause. The front of the clutch casing is open for the toggle levers, and any oil floating about is swished in and on to the fabric. MECHANICS JOINTS. We thank you for your remarks. The trouble should be cleared up, but apparently the design is too near the margin for a 100% job. OIL TEMPERATURE. The car was stopped at breakfast time and the slot cut in the under pan. We hope for the best, but our temperatures have still remained high with the air temperature below zero.
