Vehicle is a 92 Toyota Tercel, 4-banger, w/4-spd manual trans and over 100K
We did a basic tune-up on the car back in July (plugs, oil, filters, PCV valve) and the car has run fine until recently (maybe a 1000 miles or so). Daughter drove car back to school last weekend and ran into rattling noise while going uphill.
I'm thinking valves/lifters but not certain. Daughter checked oil level, which was fine. She didn't complain of overheating, large parts falling off the vehicle or any other symptoms, so I'm at a loss to guide her.
Advice to what to troubleshoot for would be appreciated.
