Engine Mechanical problem
1996 Mazda 626 4 cyl Front Wheel Drive Manual 170000 miles
I have an engine knock on a 96 Mazda 626 4 cyl 170k mi. Can't afford another car or engine right now. Any ideas? Thanks
- If I pull the lead from the no. 1 cylinder, knock goes away.
- Changed oil, spark plugs, leads to spark plugs
- Tried Lucas oil additive
- Precision Auto diagnostics: said noise from lower engine bearings
Could try replacing rod bearings on #1 piston. Need to drop oil pan
. Remove rod cap ueswood or plastic like chop stick probe top bearing out replace coat new bearings with Lithium grease. This is only a try no way to know if it will work depends on how scored crank journal.
Hope this helps
