wifes stethescope revealed a knock in the 4th cylinder. I held it on the push rod cover. OK, the oil pan is off.....no metallic pieces, nothing obvious in the oil. Drip, drip, drip.....will wait tonight....after all, tomorro it should cool to 102 here in charlotte. so guys, what should I try and wiggle....what should I look for around the crack that would correlate with a rear cylinder knock...will it be obvious ?????
