Omega General Help / Re: Cleaned AICV and jet, revs still erratic,what next

« on: 04 October 2008, 14:52:51 »

Hi I did all that and eventually removed the intake manifold to find the gasket in a very poor condition.  Replaced the gasket and it was fine  ... until now.  

I think my crank sensor is throwing a wobbly now, seems to be blowing back through the throttle body, getting tired of it now.

Omega General Help / Re: LPG fiddling

« on: 26 March 2008, 21:24:43 »

Hi Just a thought, although I run a 2.0 on a single point / mixer I had to uncover several problems.  Such as ICV, Replaced to make sure, Vacuum leak on the inlet manifold gasket (probably made worse by a backfire) and Cam sensor. All replaced and runs like a dream.

There's an lpg parts store on ebay who have all manor of anti backfire devices. http://search.stores.ebay.co.uk/lpgparts__Anti-Backfire-Devices      Contradiction really as these devices just minimise damage. Backfires do happen but with the ABD fitted it just blows out with no adverse effects in the inlet tract.  I used a porche airbox saver, simple to fit and cheap too.  I've also heard that the sgi systems are less economical as there is no loss of performance.

I hope this helps

Stalling is a common problem. 1st try ICV and small breather from rocker cover to inlet manifold, there's a how to in the maintenance guide, Although I did this, the cam sensor EGR valve and a new inlet manifold gasket before finally sorting  the stalling and rough idling. All available in the maintenance guides.    Lift off the selector gaitor and check for secure fasteners.

Omega General Help / Re: reverse lights

« on: 02 March 2008, 20:47:47 »

I've just repaired a similar problem with my fog lights, the wiring is carried along the same part of the loom to the boot lid. I traced the break in the section between Gromet from boot sill to inside just behind the spare wheel. As this section is in motion with each opening it could be anywhere along the length from sill to boot lid.  I tapped into the loom behind the spare wheel and replaced the broken wire.  You could check the resistance at the switch and work back from there.

Hope this helps.

Omega General Help / Re: Problems Running on Petrol.

« on: 26 February 2008, 19:47:48 »

Stripped inlet manifold, evidence of bodging apparent by previous owner or garage.  Wrong stud inserted at back and too short so no nut there, and manifold came off very easily with most nuts little more than finger tight, the gasket came away in peices with a huge gap in no. 1 intake section. Blanked off EGR and it seems to be ok now on Gas and Petrol. Thanks for your input.

Hi Thanks for all your suggestions, EGR erm... no thats the first thing I'll look at though.  I've traced all the injector wiring through and soldered in the Injection modulator which sits nicely in the relay box. I've repaired the fault codes recently, with a new Cam sensor the EML light has stayed off since.

The car Failed MOT though on the front wishbones which of which I did one today.  Next tomorrow.

Thanks again.

Omega General Help / Problems Running on Petrol.

« on: 12 February 2008, 20:00:50 »

I think the original suject line was mis-leading.

Hi Just wondering if anyone can point me in the right direction to solve a problem I have with my Auto 2.0 16Ver 1994:

I think there may be air entering the combustion system somewhere but I'm blowed (No pun intended) if I can find it.  On gas the car runs ok, very slight rough tickover but it's a mixer system and I can live with that. The problems start with running on petrol though. Its usually the other way round...  However cold running is a nightmare, keeps stalling until warm and then sometimes when warm too.  

When warm and standing it seems to run fine mostly, until it's in drive, while it still runs it starts to hunt noticeably with the car rocking rhythmicly slow, occasionally the revs will drop and the EM kicks in with a rush causing a surge.  I've done the breathers and rocker cover gasket all are now clear. I've even installed a brand new ICV. I'm considering opening the throttle butterfly slightly to try and aleviate some of it.  I'd be very gateful for any suggestions or remedies.

Thanks in anticipation.

Omega General Help / Re: how to replace piston?

« on: 26 January 2008, 23:21:56 »

I Assume you've removed the head, and sump. Remove Big End Cap, Push Piston out, Gudeon Pins are an iterference fit so you'll need to use a suitable drift. To replace pin, bake the piston, freeze the gudgeon pin and drift into place, aquire/borrow piston ring compresor slide piston back in connect big end cap (Right way round) to correct tourque and reverse sump / head removal sequence. Or as in previous messages replace engine and do a complete overhaul of the original engne.

A stout pair of long Nosed Pliers could be the answer for the 3 hole retaining screw. (Works for mine).

Try a local indipendent, they can be a little more aimiable when it comes to Locking Wheel Nuts.

Omega General Help / Re: Help!! Snapped small breather hose jet!

« on: 18 January 2008, 19:28:42 »

Sounds like you may have lost the banjo washers when removing the jet this would possibly cause a leak. I always loop the washers with cotton to retain them when re-assembling. Good luck.
