My 1997 1.6L Corolla with about 180K miles developed a severe oil leak. I topped off the oil and was driving it to the shop. The oil light had not come on (not that low) when the engine developed a knocking sound. I immediately stopped & called for a tow. The shop has located & repaired the oil leak, but has only told me that a "rod is bent" and their specialized service technician will check it out today. Any ideas what I might expect? What questions should I ask? How much could various repairs run? I can't buy another car at this point. My finances are EXTREMELY limited. I need to make a cost effective, affordable choice. Any suggestions are welcome. I've been getting about 25 mpg, so compression is apparently good. While they are repairing the "bent rod" should I have them replace the timing belt as preventive maintenance? Would that save on labor costs, since they will already be opening the engine?
I have a 2002 Highlander (V6, 4WD) and last week the check engine light came on. Went and got it tested and it threw the P0330 and p0325 codes for the knock sensors. Which I'm making plans to get replaced. Now this week, when driving on the highway the RPMs will occasionally be at 4thousand. When I stop and restart the car the problem seems to stop for that trip. Is this irregular RPMs potentially connected to the knock sensor codes I got? Or does this sound like another problem.....? Also, would knock sensors be an ok part to pick up from the Pick-a-Part? They seem to be pretty expensive brand new and there are two in this vehicle...just looking for more economic options.
