My Black Brick

My check engine light has been on in my brick ever since I drove through flood waters and stalled out. I’ve changed oil and flushed the transmission but ever since I’ve been getting awful gas mileage. Like 10 mpg city and 15 highway. I haven’t had the funds to get it looked at and am just not going on any long trips. The car runs fine on the highway but lags around town. Stepping on the accelerator just causes the car to pause for a moment, then revs normally. I’m guessing the engine is flooding with an overload of fuel, because if I’m steady on the pedal I don’t have too much of a problem.

I figure the problem is with the O2 sensor, even though I think it’s pretty new, like less than a couple years.

UPDATE: Now that I look at pictures of my catalytic converter install, I realize I have another O2 sensor I can test with. My old cat had cracked but I still have it in my basement, with O2 sensor attached. Looks like I need a new wrench and should start troubleshooting.

Looking at my iPhoto set I see I have tons of pics that I never got around to posting, of things like my overdrive install, flame trap, cat converter, etc. One of these days I should just dump it all onto this site.

Turns out one of the oil seals I installed was busted or misaligned but now we’re back in shape, thanks to some professional help. While it was down in VA we had the windows tinted, a scratch repaired and nice paint detailing. It’s glossy like a new bowling ball and slick as an ice cube. We’ll be driving cool this summer, that’s for sure.

The weather was pleasant this weekend for checking out my oily crank. Unfortunately I wasn’t able to enjoy a leisurely cruise down the boulevard because of the mega oil leak.

I await a call from DB Volvo on my minor catastrophe. I drove the brick cautiously along the inner loop of the beltway from Braddock Rd. to Route 66 and Don Beyer Volvo, belching plumes of smoke whenever I went over 40 MPH or 2000 RPM. After a short wait I was told none of the mechanics who worked Saturday would be able to service and I’d need to wait till Monday. I was fortunate enough to get a ride from my mother back up to NJ w/ the kids.

Here are shots of some of the work I did. I got plenty of “before” shots but was so beat at the end that I didn’t get a good pic of the new seals and timing belt. I did get one of the old and new covers though.

Here’s a view of how the seals looked when I took the pulleys off, then after I’d removed the seals and cleaned the front end. At least I’ve got a new tension roller.

After a day of rope tricks and greasy fingers I finally changed the front seals, timing belt, covers and V belts, only to have what looks to be a worse leak than before. I drove the brick for about 5 minutes then opened the hood. There was a trickle of oil leaking out of the timing belt cover and upon opening it up I saw all the work I did basking in hot oil.

I figured I’d give it another run, so this time I drove on a higher speed boulevard until I started smelling something burning. I looked in the rear view and there was a cloud of smoke trailing me. I was driving in a loop and pulled the car back into the driveway and checked the dipstick. It looks like I went through a 1/2 quart in about 4 miles. Wonderful.

I’ve got an appointment at Don Beyer Volvo, Falls Church, VA for 8AM tomorrow. I just can’t go through this crap again, especially since I can’t tell where the leak is coming from. They’re offering 15% off service for cars over 120k miles. Lucky me.

Below is a sketch documenting how I checked the over-drive relay after I lost the use of over-drive last winter. It follows a technique I’d seen posted on the Brick Board, probably by Dave Barton. It took a while to troubleshoot but I eventually sucked it up and got the $40 Over-drive Solenoid Bypass kit from IPD and it’s worked great since then.

In the continuing saga of my exhaust leak, I’ve discovered a new issue. There’s a big crack in the pipe going into the catalytic converter.

I think I missed it last time I was under there because I was looking from the other side. But with the camera the hole reveals itself. It’s only 2 years old, so I don’t know why it would have a fracture like that. It looks like it happened from over-tightening.

I posted to Brick Board here.

I just posted this on the Brick Board:

My brick rasps awful loud and I went under and found where it’s leaking. It’s at the flanged fittings where the header meets the cat. converter. I got a generic exhaust gasket from a local shop and it fit correctly. The old one was held on by one out of the three holes.

I tightened up the bolts but it still leaks. When I hold my hand around the back of the flange for the cat converter I can feel exhaust leaking out. It’s on pretty tight though, so I’m not sure why it would still be leaking. I tightened each bolt equally. Could they be too tight? Bad gasket? Bad flange?

After waiting an excruciating 18 hours for my FCP Groton order, it finally arrived via UPS. Did I really just order these front wheel bearings yesterday afternoon?

Wait a sec… is the name on the box really the name of the company? FAG? WTF? Do they offer t-shirts with their logo?

Finally pulled the glovebox out and checked the Overdrive Relay switch. It looks fine but, after trying Art Benstein’s test of the current at the relay, it didn’t give a response. I’ve read that the circuit boards often need to be resoldered, so I’m thinking I need to bust it open and check, before springing $43 for the part.

We drove down to Northern VA this weekend to visit my parents and had a chance to check out some museums in DC. Pulling onto the mall at 10:15 on a Sunday allowed us to park right in front of the Capitol, the National Gallery and the museum of the American Indian. It also gave me a great backdrop to photograph the brick with it’s new lowering springs.

The 4.5 hour ride down was quite pleasant. I’d been nervous about the stiffness of the springs but overall everything is fine. On long stretches of highway it felt about the same. The only problem is large dips and rises. The car doesn’t absorb them like it used to; you ride the full height and depth. Luckily there’s no bottoming out or shock crash-through, and no scrapping the exhaust on speed bumps.

I’ve been driving my wife crazy taking turns though. It’s so easy and precise to steer that you can lose a sense of your speed. Of course I was pushing the car a little, sending our case of Trader Joe’s Two Buck Chuck sliding around the trunk, and forcing Desiree to grab onto her seat. Fun!

But, as always, I’ve got a new gremlin in the car. No overdrive. It kicked out last week, so the whole drive was spent at 60mph in the right lane at 3200rpm. I gotta figure out if I want to check the OD solenoid, or just get the ipd bypass kit.
