I had my 2012 Prius C (166,000 miles) at the Toyota dealership for an oil change yesterday. They noticed a small puddle of oil under the rear end and showed me the photo of it. But I haven't seen oil on under my since I brought it home from the dealership. The total cost of the repair is $3660, including $2710 for the labor. It's a 15-hour repair so the labor is $180.67 per hour. The parts are about $300. Is the cost of this repair reasonable? Should I delay the repair until I see oil under the car?
It's a reasonable price for a dealer to fix that. An independent garage can usually do it for about 2/3rds or less. Thing is, you probably don't need to fix it at all. It is a fairly common leak point on this model, but nobody ever lost much oil through it. It's just not a big deal for most. The oil loss rate is not likely to increase over the remaining useful lifespan of the car. Wait until yours proves itself different with a puddle.
^ That. The fact that the dealer is trying to get you submit your car to nearly $4,000 worth of open heart surgery to fix a minor oil weep is telling. -what it would be telling ME is that the 'change dealer' light just illuminated..........
Sounds like the dealer is pulling the engine to change the timing cover gasket. I would get a second and third opinion until you found a price less than $1200. If not live with it but check the oil every two fill ups like your wallet and engine depended on it.
Before doing anything I'd want to see for myself. The "timing cover gasket" is more succinctly termed "timing chain cover gasket", and the gasket is a bead of specific goop, sometimes called form-in-place gasket. It's on the "front" of the engine, which is the end with the pulleys and belts, the passenger side. You can get a half decent view from above. Better would be to jack up the right/front corner (or the whole front end with a floor jack), remove the right/front wheel, disconnect and flex back any plastic panel, and have a look. FWIW, I recall gen 3 owners getting this done, at dealership, for $1700 USD. Also, apart from cosmetics, it's not that serious, especially if it's a minor leak. Attached is gen 2 timing chain info, from Repair Manual. Prius c should be similar. It does not appear to require engine removal.
