Evening everybody, I'm Dave. If anybody's from the BMW or Ford worlds you might recognize me. I'm here for my mom's car. Her mech. recently retired down to the Gulf (must be nice, right?) and I've inherited maintenance duties.
146k miles on it, she bought it as a former demo car with 1300 miles on it. Mom isn't much on preventative maintenance (read none) other than religious oil changes. I'd estimate 4-5,000 of that a year is on road trips. The rest is not much city/stop and go. We live out in the suburbs so a lot of cruising, but all ~55 or below. Unfortunately she works about 3mi from home and has probably never sped. So carbon is probably having a party down in there.
The car has been losing coolant and there's an odd rumble at idle every 20-30 seconds. No surge in idle or lurch forward, just a shaking of the whole car.
Here's what's been replaced in the past; plug wires, filters, both front CV axles, accessory belts a few times, brakes.
I realized going through it that the timing belt is from the factory :gasp:. After a panic and a good laugh I started tearing in to it. Her driving must not be as hard as I'd thought on it, she's had pretty good luck as far as reliability goes. Here's where my question comes in:
On the guides and pictures/videos I've seen there's factory paint marks on top of the notched timing marks. However mine are just to the passenger's side. When those are straight up the metal notch on the back of the crank gear is at about 1 minute (per a clock). However, all three metal notches line up. Crank straight up, both cam notches are straight up and align with the rear timing cover.
So trust the metal marks? Just want to double check myself before I turn my few hundred savings in to a few thousand mistake haha. Also, I think I found where the coolant is going. Is that the infamous head gasket failure I see? Including a picture of the data card incase that helps...
Thanks in Advance everyone.
