Omega General Help / speedometer and rpm gauge

« on: 20 October 2014, 23:01:16 »

 I've got a problem when I connect the battery back up after performing a repair the rpm gauge doesn't work and the speedometer just jiggles up and down on zero. I had originally turned the key ignition to "on" position but not start for 4 minutes to reprogram sunroof,windows,a/c...ect. I then turned the key to the off position and then started it up and that's when I realized the speedo & rpm gauges where not working. So I shut the car off and turn the ignition back to "on" and waited 4 min. again, and this time with out turning key off I turned key to start and the engine started up and rpm gauge started up and speedometer was steady(not jiggling). So today I start it up and no rpm's and speedo just sits on zero jiggling again. I performed a 4 min. key in "on" position and then to start but it didn't fix it I have a 98' Cadillac catera but its actually a Opel Omega, can someone help me figure out the source of this problem It does it just about every time the battery gets disconnected for a good period of time, but it eventually starts back to working again sometimes not until you drive it around for a few days. I thinking maybe its time to figure it out before it completely stops working

Omega General Help / Re: 3.0 l v6 flexplate to crankshaft bolts

 Hello Omega Owners Forum Folks! Heavens to Mergatroid Just wanted to give a little update, I went ahead and got 5 of the 8 bolts off by doing what webby the bear advised and was able to achieve that without twisting off the 1/2"to 3/8" adapter. But I got the other 3 off by drilling down the head of the bolt and using a screw extractor. So now I've replaced the rear main seal and will be torqueing the flywheel back on in a day or so. Thanks 78bex I google that Haynes manual on the PDF site no need to buy it now I'll continue to keep up appearances after more progress is made

Thank you so much 78bex that's very important information because in America you cannot get that repair manual in any auto parts store over here. Even if you look at the back cover of Haynes repair manuals over here for the listing of other vehicles, its not listed.

If it's any consolation, I would imagine these are stretch bolts which should be renewed when disturbed anyway, so yes, weld a nut onto it, or grind it off and get a new set of bolts.

Either way, they'll come easily since the tightness comes from the clamping force generated under the head, so once this is gone, the thread will just be loose in the end of the crank.

TORX fasteners are great for automated assembly in the factory, but not so easy to remove with hand tools.

O yes I try to do some home work before starting projects on this car so I've already ordered my bolts #09126505 from gmpartsgiant at2.90 a pop just waiting for them to arrive. I don't know where to find a good manual on this car I searched but it would probably be a Vaxhall thing. Saw a repair manual on a EU e-bay for I think omega b or somrthing like that but it looked like a children's fairy tail size book so I passed. Is it just me or does everyone else thinks The Red Baron looks like Bruce willis

Hey there The Red Baron, is that from experience ? because if that's true then that's gonna take a load off my mind It kinda makes sense cause basically all the pressure is up on the head as to being down in the threads

???I guess grinding it down would be an option but then that would be at a point of no return and then I would have to figure what I could use to bite hold of the stud to completely remove it. That is coming too close to having to replace the crank and if that where the case I would just junk it.

when you grind them off they will come with fingers

;)yeah Serek I get your point but I would be at a loss at figuring out what tool II would use to bite onto the fingers

 alright I'll give a look. I was using a 3/8 drive ratchet w/E-14 socket its a snug fit but I don't have the strength to break it lose and I have a E-14 impact socket but its 3/8 drive to w/side impact ratchet it will lock up and I still don't have strength to break it lose. I have a 1/2 air impact but don't have that size socket. So I'll try getting a E-14 in a impact 1/2 drive. But in the mean while I got to know how to get the ones I've buggered up does anyone think welding a regular size nut to the end would work or are there any other option. Well thank you for the link I'll check it out in the meantime I'm all ears open to anything. We'll get back as soon as any progress is made.

Hello forum folks ! Need a little advise here. I'm trying to remove 8 torx looking bolts from the flexplate securing it to the crankshaft so that I can replace my leaking rear main seal. The problem I'm having is using a 3/8 drive t-14 socket and ratchet. The first bolt I couldn't budge it at all and it kinda buggered up the edges. Any advise from correct tools to correct procedure would be greatly appreciated Thank you

Hello forum folks, I'm new here. I'm over here in texas I signed up because I have this Cadillac Catera with the opel omega 3.0 l v6 engine and I think it would be good to get the necessary repair advise from the folks that work on them all the time. I'm also on the Cadillac owners forum too but the owner ship of Catera is diminishing due to the problems with this car and age so with that the forum lacks the support to which I seek. I've come to this site numerous times as a guest and have found a lot of help with issues to my problems by reading and searching the general help forum. But now I need to ask some questions for the issue I'm having now concerning the 8 torx like looking bolts securing the flywheel to the crank. I'm in the process of replacing the rear main oil seal due to it leaking. So I have to transmission off and I placed a torx socket(T-16) on one of the bolts to loosen it but its just messing up the bolt and not budging. So before I really mess totally up I thought I'd give a shout out for some advise.
