Omega General Help / HBV Falied Again

« on: 17 May 2014, 23:01:03 »

Just replaced the Heater Bypass Valve on my 3.2 (a testing little job and cutting the hands to ribbons), the second in a couple of years. Took the top off the old one and there's a rubber seal inside. I presume this is the area that fails? Is there any alternative for the next time that might last a bit longer than the GM part or is this as good as we get? Any other possible reason for early failure?

Further info on the replacement alternator.
Vauxhall lists part number R1530056 for the 3.2 Elite which comes with wrong terminals.
I understand from the posts that to get the correct terminals, an upgraded 140A is the one to get which carries part number R1530055 I am lead to believe?
Could anyone verify this number?

Reading the post by SMD, this is what I found when looking to replace my alternator.
Couldn't add to posts because it is locked.

Omega General Help / Misfire whilst idling

« on: 16 December 2013, 21:26:46 »

A misfire has developed on my 3.2L Elite Saloon whilst moving slowly in traffic, using only idle speed. This also happens when coming to a stand still in drive gear. If I shift into neutral at this point it seems to disappear although as time goes on, I think it is getting gradually worse.
Cam cover gaskets and breather done last year so the plug wells should be free of oil, and it appears free from any rainwater under the bonnet in wet conditions.
It would seem that one of the coil packs is breaking down and I need to try and identify which one?
Any advice from similar experiences would be welcome.

Omega General Help / Alternator

« on: 01 March 2013, 22:19:47 »

I've been reviewing the various posts and maintenance guides regarding alternators, mine having recently packed in on my 3.2 Elite Saloon. Some really good and helpful info here.
What I'm not clear on is the replacement remanufactured alternator. It appears that both the 3.0 and 3.2 have the same part no and the terminals match those of the 3.0, which is not the same as the 3.2 Elite.
Does this mean that the remanufactured replacements only have terminals to suit the 3.0 or is it possible to obtain one that matches the 3.2?
I've got a replacement but have had trouble fitting the cables due to the terminals.
I would be grateful for any info.
