I recently had my 2001 Corolla break down on me. It only has 50k some odd miles and was running relativity good besides the fact that I was putting around 2 qrts of oil into it every 1 1/2 to 2 weeks. Mechanics hadn’t mentioned anything about a leak, and I never saw anything that would suggest leaking. It seemed to me it was just burning through it.
On the day it broke down, I assume it was definitely an oil issue, yet the check engine light had only just popped on 5 minutes before it broke down. I work at a school with an ex-Toyota mechanic who took it apart and gave me the back camshaft. The bolt and pin had snapped off. He also mentioned to me that I would need a valve cover gasket, new spark plugs, a fabricated pin from a machine shop and a new bolt (the latter 2 parts being for the camshaft). On top of this he did mention that although the oil seemed good (nothing metallic in the oil), the 1 & 4 pistons were an issue.
My question is A) is it worth me going through all the trouble to get a fabricated pin or should I buy a new camshaft? B) if I buy a new camshaft (or get one from a scrapyard) and he puts it in, what are the chances that there are more issues (in other words; how much is this going to cost me & is it worth it) ? C) if the car is completely shot, what can I expect to get if I scrap it for parts?
I really appreciate anyone who can help. Please know that this is all coming 2nd or 3rd hand and that I only have limited car knowledge. Layman terminology would be appreciated.
