Maintenance

[AC HUM1]

I have a 2002 H1 and decided to do my own maintenance to save some dough, so I ordered a service package of filters and crap from bluehummer.com.

Over the weekend I decided to change my oil and was going to do the fuel filter too but didn't when I ran into a problem. I used 2 gallons of Shell Rotella T 15w40 with a Wix oil filter which came with the service pack. After getting the oil done, I fired it up and it ran fine for just about a minute. Then I climbed out and it went dead. I figured it was the oil filter filling up, so I tried starting it back up and it wouldnt fire up. I checked the oil level and it is right at the "p" in the word operating range on the dipstick. Is that overfilled or is this normal? After a bit I started it back up and it went dead again, though the 3rd time I tried it, it ran fine. No matter what I do the oil level isn't falling between the operating range.

What should the oil pressure gauge be reading? I must have never paid it much attention as it seems to fluctuate alot, it seems to be staying right below half.

Any ideas if I overfilled this sucker and why the heck would it go dead like that?

No idea why it went dead... but I bet you definitely overfilled by at least half a quart.

The TDs use 7.5 quarts, not the full 8. Also, how long did you let it drain?

i think the '02 models still had an oil pressure switch that cut fuel if oil pressure dropped below 5 psi. Go with Justin's oil level and switch out the wix for an AC delco filter and see what happens. rule of thumb for oil pressure = 10 psi per 1000 engine rpm. the oil pressure gage should show about 1/2-3/4 when cold and 1/3-1/2 when warmed up.

Thanks for the info I finally got around to it today. I got the AC delco filter and 2 more gallons of Shell Rotella T. Changed it out and let the oil drain out until it stopped completely this time.

I put roughly 7 quarts in to check it on the dipstick and finally topped the 1/2 quart off and it is staying right above middle in the cross hatched operating range section on the dipstick. I fired it up and it was running fine, so I decided to go ahead and change the fuel filter.

Drained the fuel out and stuck the filter in, it all went fine. It started right up after I got the fuel filter done, but now it is starting to go dead on me again. More so than last time. Doesn't seem to be any pattern to it, the motor is just shutting off? I think my batteries are getting a bit weak, the cranking had already been being a bit dull but still starts fine, could that be a reason it is not running right? Could there be air in the fuel lines? At idle the oil gauge is staying right at 1/4 to 1/2 all the way through until it shuts itself off. Any ideas?

I did pull the air filter out to check it, it was perfectly clean so I stuck it back in with no problems. Maybe I didn't get it in there right?

Did you bleed the fuel system after you replaced the filter?

[AC HUM1]

Nah I didn't. I did try to twist the black plastic valve on top of the fuel filter but it didn't seem to budge. I just started it up straight away after doing the fuel filter and it ran ok for a few minutes. I checked for leaks and it seemed to all be in order. I shut it off and when I went to drive it around the block later it started going dead on me before it got out of the garage. Now it is just shutting off every few minutes for the most part.

Though, it was shutting off like this last weekend after I changed the oil only and I thought I had over filled the oil slightly. Nothing had changed prior to that, it always ran great.
