The correct installation method is to install the filter pac assembly so the basket "handles" face in- board. In other words, the "handle" end of the basket goes into the compartment first. In case you can't find the FSN for the filter pac, it's 2940-751-7090 (P18868). 3. Leaky intake air duts. Look for loose clamps. misalined parts, holes or anything that looks like it'll let dirtr air sneak into sour engine's induction system. Dirt). unfiltered air can che~ sour engine to bits in a short rime. o LUBRICATION gine oil before and after eern , an overnight stand the lepel maN creep up to 1-3/8 inches above the FULL mark; this as OK. 2. logged lubrication system. If this is the case, change the oil filter elements (FSN 2940-555- 6348), clean out the filter shells, drain the contaminated engine oil, fill the engine with OE 10 and run from three to five hours. Repeat the flushing until all the sludge is washed out of the system. When it's cleared, again replace the oil filter elements and fill the engine with OE 30. 3. Wrong grade or diluted engine oil. LO 9-2300-216-12 and LO 9-2320-238-12 specify OE 30 for expected temperature above + 32E and OE 10 between + 40'F and + 10WF. The use of a too light weight oil, either the wrong grade or the right grade diluted with fuel can cause engine overheating. A situation like this can be spotted by a low oil pressure reading on the instrument panel gage. 65
