Expert: Ted Ritter Date: 7/15/2008 Subject: oil pump on an '89 SR5 P.U. w/ 3.0
Question My truck has 235,000 on it. I've been trying to stop my oil leak. I've replaced both valve cover gaskets, cam seals, oil pan gasket and I still have oil leaking from just under the oil filter in a small stream. Could it be the oil pump (seal) and 'O' ring? The leak appears to be on the pressure side of the engine. I'm going through about a quart of oil every 200 miles. Would you recommend just replacing the oil pump while I'm in there?
Answer In order to fix this leak the front engine covers need to be removed and all gaskets and seals replaced at the front of the engine, the oil pump is located inside the oil pan, this is not where the leak is coming from, the leak is coming from a seal between the timing cover and the engine block.
