Car Quirks


#1

Indy Jim was elsewhere talking about Geiger’s car and its quirk for starters (3 of them).

My quirk is the transmission input shaft seal that, after 3 replacements, continues to leak. Can’t wait to replace another contaminated clutch at mid-season.

We all know about Kelly’s multiple clutch strap failures.

I think Jim Levie’s car still has a mystery cut-out at 5500rpm?

What quirk does your car have?

An engine, wiring harness, new sensors, and the like has almost eliminated my main problem. I still get occasional CEL’s for the fuel pump relay, but at least I can reach the redline.

Now I have a strange failure to park in the wipers…

Have you ever figured out the weird fuel problem on your car?

I also have a transmission that insists on leaking from the input shaft (not currently in the car). My solution was a differ gearbox.

Mine is slow. :blush: Although it could be the driver.

Seriously, my car is a little flat at 4700-4900 rpm.

I also saw the oil pressure light in a long left hander for the first time this past weekend. No crank scraper yet.

Jim, no on the fuel problem.Any further ideas?

Thanks for the story about your gearbox leak,too. I continue to use mine 'cause it shifts good and it will eventually crap out its internals. Until then it will be clutch disc changes.

I’ve thought about this on and off ever since the Toy Run. The engine ran way too long with the fuel feed disconnected. That suggests that there was a good quantity of fuel in the intake. The possible causes of that could include excessive fuel pressure, leaking injectors, or something that is interrupting spark. I tend to discount an ignition problem since disconnecting the fuel feed allows the car to fire. That leaves excessive fuel pressure or leaking injectors.

I think you’ve swapped fuel pump and FPR, so one might tend to say that excessive fuel pressure isn’t the cause. But if the return from the FPR to the tank is partially plugged, you could still have excessive fuel pressure. It might be illuminating to tee in a pressure gauge and see what is really going on.

I have a spare set of injectors and I’ll try to remember to bring them to CMP. Along with my pressure gauge.

My wipers, no matter what I’ve tried, will always rest in the middle of the cycle. The only cure so far has been tons of Rain X and pulling the fuse until it rains.

This thread has some good e30 quirks,

Jim, just helped a friend with a similar problem…solution was a new tank. The problem was a collapsed tube inside the tank return line. As a test, connect a pressure gage to one of the fuel lines and put on the hood so you can see it. Monitor pressure through the gears…if it increases as you run, you probably have a tank problem. Friend replaced his with a new and problem solved. Chuck

JP, my car did (the white one). I figured it was that the lever arm that mounts on the wiper motor must have shifted, but I was too lazy to fix it (not an easy job).

I have another quirk to present. We pulled the adjustable fuel pressure regulator off Mike’s car due to new rules in prep for Feb race. Replaced with stock FPR and now the car will not start. We have spark and plenty of fuel (plugs are wet after excessive starting effort). Any ideas?

Ignition cuts out. Chased the problem all year…first it was the fuel system, as it only happened in right hand turns. Fixed fuel tank, purged lines, new filters, new pumps. Good pressure. All’s well, right?

At Road A, it cut out a few times and I dismmissed it as low fuel (but it was near full)

Then, during a lesson at CMP after Road A, after an hour or so of track time, it started to cut out intermittently, right, left, straight, it didn’t matter. And it wasn’t just a sputter and stall, it was literally as though I turned off the ignition. I got towed back in after it completely shut off between 12 and 13.

Found a missing module under the hood (driver’s side).

Replaced said module(s), zip tied down the box so they couldn’t bounce out, and headed off to Rockingham.

During the Saturday sprint race, it ran great but I lost a tire and had to pull out.

Sunday, with a better alignment and new tires, went out for the inverted start race, and mid-race it started cutting out hard…nearly stalling on the back straight. Since I’d blown the start in turn 3 and was working back up from the back of the pack and would never catch the e30’s, I packed it in.

I have asked around, but other than the fuel, no one seems to have an answer. The car is sitting right where I parked it after the Rock. I’m hoping to find time and funds to have it ready by the next round. Any thoughts on the ignition cut-out?

Thanks!

My wipers run continuously. I finally just pulled the fuse.

Search for a thread titled “What have I missed” for ideas about possible causes. If that doesn’t help, PM me and I’ll try to help you sort out the problem.

My wipers come on when I brake hard - only once or twice and then re-park.

I have the fuel starvation problem as well, long right handers when the tank is below 5/8’s - I probably need to replace the tank and/or anything else that could help it…

Joe. Bet it is the crankshaft position sensor.

The “module on the driver’s side” that you spoke of is called a fuel pump relay and ALL e30 drivers should zip-tie the relay in place, cause it WILL bounce out and the car will not run.

Jim Levie: car ran like it should and I was doing a Skeen drive-around in Sundays race. It was refreshing. I hit some bumps and the fuel pressure gremlin kicked in , again.
Gremlins. I’ll keep you advised as you are the man to see for troubleshooting in the pit area. Thanks so much for all of you help. Carl and Bob Shields were tremendous help too.
