| Question: | 1994 Mitsu eclipse 1.8 liter
auto. timing belt I am working on two 1.8 liter engins. How important is
it to align the timimg mark on the oil pump when changing the timing belt?
Before I remove the original belts --on both engins the oil pump timing
mark is about 30 degrees past the marks on the engin. Also on one the balance
belts is out half a tooth. Thanks, larry |
| Answer: | Larry, The if the timing marks are not met correctly on the oil pump sprocket, that will through off your balance belt, and your car will not run smooth. Your camshaft/crankshaft sensor may retard your timing, and your acceleration can be limited. If the engines were running well before the old belts were removed, and
you will be reinstalling those old belts back on the car, then you can
probably get away with putting the old belts back on with the same orientation.
But if you're installing new belts, you will definitely want to make sure
ALL timing marks are aligned; on the camshaft sprockets, the crankshaft
sprocket, and oil pump sprocket. It is important. It's CRITICAL on a 2.0L
engine, but even the 1.8L engine will benefit from the correct timing
and alignments. |
