Omega General Help / High Idle- both banks running lean- vacuum leak fuel pressure regulator valve?

« on: 03 November 2019, 11:17:52 »

Good Morning from Chilly Connecticut.
My 01 cadillac catera has a vacuum leak coming from under the plenum, back towards the firewall. Symptoms are: loud vacuum leak sound, 2 error codes (lean on both banks), and and high idle, even when warmed up. If I carefully direct carb spray (not easy cause plenum in the way) at the fuel pressure regulator valve, it raises engine revs. there are no fuel leaks at the valve, and the vacuum line connected to it is not cracked or disconnected.

Does this sound like a faulty fuel pressure regulator valve, or should I be looking/testing something else?

Omega General Help / radiator change- 3.0 cadilcatera

« on: 09 November 2017, 00:51:45 »

Hi Folks,
have a cracked radiator, going to change it out myself- it looks pretty straightforward, only thing a bit confusing are a pair of hard cooler lines that run up and curve over the top of radiator, and fasten with a torx screw on top, regular hose clamps on bottom. I am guessing they are tranny cooler lines?- any specific precaution i need to take before I remove?
and as long as I am here asking, any tips or tricks for the rad change?

Thanks for the help!

Omega General Help / Discontinued Parts for Catera

« on: 06 September 2017, 15:36:16 »

Just put new tires on and now want to have car aligned, but the shop says the driver rear ajustment tube is seized and needs replacing. I am struggling to find it, its a rear lateral link (rear tie rod) for my 01 catera v6- gm has discontinued the part, and i am coming up blank with ebay here in the states. Anyone know where I may be able to source this part?

much appreciated,

Dave

Omega General Help / V6 small coolant leak-chocolate foam under oil cap

« on: 20 January 2016, 04:47:40 »

my 01 v6 catera has lost about a half liter of coolant over a 2 month time span. (So little in fact, I only noticed it because the dummy dash light came on). A tiny puddle forms under the alternator, on top of oil pan. thought it was just a hose or something fairly simple, wanted to stave off the repair until spring=warmer weather.

But today while performing routine oil change, I notice some brownish/chocolate foamy condensation under oil filler cap?

Oil stream during change looked okay- just dark oil from 3K miles of driving

My work commute is an hour each way and the car shows no problems. Runs perfect- normal operating temperature, no oil loss, strong interior heat, no skipping, No CEL's.

The maintenance thread outlining head gasket repair procedure claims Head gaskets rarely fail on these hearty 6 cyl engines....and since the car runs perfect I'm keeping fingers crossed.

Could the coolant be mixing with oil? Could the car run perfect with that happening?

any thoughts or insights are greatly appreciated.
