Omega General Help / Cam Cover Bolt Seals

« on: 08 April 2018, 12:36:19 »

Last year I replaced both cam cover seals and O rings as existing had started weeping and expect they were originals.

Since then all has been spotlessly dry of oil until I noticed last week the back top bolt head on the passenger side cover had traces of oil appearing around the edges and starting to mist onto the black cover.My assumption is either the O ring has let go or maybe it got displaced when I fitted them last year but would of expected to see oil before now.They were all torqued correctly to 8nm and genuine parts were used.

My plan is to remove the bolt completly...clean away the oil from the cover and refit the bolt with a rubber washer in between the cover top and the bolt/washer as I think it is over kill removing the oil tight cover completly along with the cost of a new cam gasket/8 O rings and the potential for it to possibly happen again.

Breathers are clean and all else seems fine so just wanted to run the above by for comments or if anybody has had this happen before and resolved in a similar way

Omega General Help / Oil Pressure Switch

« on: 19 November 2017, 09:09:37 »

Reading several recent posts re leaks around or by the oil pressure switch think this might be the reason why I also have traces of fresh oil on the top face of the sump directly below the alternator .

As oil doesn't seem to track much beyond the front edge of that area I am suspicious that the oil pressure switch may be my issues.

What is involved in removing and replacing it and is the switch the same across the range .

Thanks

Omega Electrical and Audio Help / NCDC 2013 nav issues

« on: 08 November 2017, 15:22:46 »

Bit of advise required please guys.

Nav unit has always been temperamental since I first acquired it with paired screen some years ago.

As the disc would get ejected with message advising dirty and couldn't be read ,I went down the route of getting a new laser from Gerbers in Germany.Whilst I rarely ever used the nav system

Omega General Help / Ignition Coils

« on: 15 December 2016, 11:22:47 »

Traced the misfire on 2/4/6 bank as the coil pack has badly split.

In my spares stock have found a brand new Bosch coil pack for 2/4/6 bank although whilst visually its identical cross checking bosch parts catalogue it is for a v6 signum/Vectra.

Will this be ok to use or are they different internally ?

Omega General Help / Headlight Aim

« on: 01 July 2016, 20:26:30 »

Decided to investigate the poor headlight aim on my Elite yesterday as despite replacing both busted adjusters with ali retro fits last year I  have never been too impresssd with performance of lights .Bulbs are all good/health so decided to strip them both down again and investigate .

Found that O/S metal headlight adjuster had gone to the extent of its travel and had albut fallen off the thread which got me thinking was I adjusting the right screw for the right position.

It had been my understanding for as long as I can remember that the inner screw.(nearest the center of the car ) was for the up,n,down adjustment and the outer screw ( being nearest the wing) was for the left,n,right adjustment.

Had a read of the Haynes manual and I think I have been doing things wrong 
That states..... Inner screw is for Horizontal ..which I am assuming is up,n,down
                      Outer ................Vertical .....which I am assuming is left,n,right.

Can some knowledgable person kindly put me out of my misery.Which does which ..as despite spending an hour last night with car against a darkish wall I failed to see much difference .albeit I was only making adjustments to the Inner screw.

Help please

Omega Electrical and Audio Help / Brake Pad Wear Warning Message

« on: 29 May 2016, 14:43:54 »

For about the last few weeks almost on every ignition start the brake pad wear warning message has appeared on the display,despite no wear sensor being fitted for the last 18 months and both wires soldered and heat sealed together.The message can be cleared and doesnt every reappear whilst driving so it would seem the sensor wire bridge isnt at fault.

Yesterday as part of my scheduled plan both sets of front brake pads were replaced,and whilst I was in the nearside wheel arch I decided to have another look at the wiring.Just to be belt,n,braces I recut the sensor wire and again resoldered and heat shrunk the connection.

This morning went out to work and on start again the pad wear sensor message appeared and has continued as before only appearing on a ignition start.

Is is possible to totally disable this within the relay/loom or fuses as its now starting to do my head in.

Cant see and damaged wires from the plug up into the point where it dissapears into the loom inside the inner wing.

Help please

Omega Electrical and Audio Help / NCDC 2013

« on: 19 March 2016, 17:55:48 »

Had new laser fitted last year and nav has behave pefectly since then,although in truth very rarely gets used but disc has always been in machine.

Today I pulled of motorway slip road and whilst listeneing to radio suddenly entire head unit shut down.Nav disc ejected .

Pushed on/off button and radio and head unit fired back up and has worked faultless since but nav will refuse to accept disc as everytime inserted it ejects .Have cleaned disc although it was spotless and is a genuine 2008/9 navtec disc.

Any ideas as would of hope new laser would of lasted more than 8 months given that it hasnt been used for more than 5 hours max intotal in that time.

Omega General Help / Cabin Heater Fan

« on: 17 March 2016, 09:56:59 »

Heater fan has been quite noisey for last few weeks and last night it decided to completly stop.

Have checked fuse #33 and intact.Have put a 12 volt across fan terminals and it works albeit quite noisey so thats would seem to need attention/replacing with new.

Assume only other failure part is the "hedgehog resistor" as when reconnected fan doesnt work .

Are all parts the same across the range ,and are these safer buying new or is second hand being a genuine part the best route ? as would prefer to have both parts to hand prior to repairs start.

Omega General Help / Bilstein B4 Rear Shocks

« on: 13 January 2016, 20:31:53 »

Measured the shaft end of B4,s to compare with OEM shocks and as advised by previuos posts the B4,s are around 12mm shorter meaning the  original GM fixing set will not fit and will require either using that supplied with the shocks or sourcing fixing set for an Estate.

Spoke with Dealers this morning and both upper and lower rubbers are only available from Germany and the metal sleeves need to be ordered in a bag of 5  despite all cars only ever needing 2 ...typical GM.

How bad are the fixing supplied by Bilstein as cant see any real solution now ?
