Thanks, good plan but whats ABS? http://www.autobahnstormers.org/ 
?
I have found some oil around the front of the nearside cover ...... Tried the John Cleese aproach by hitting the car with a tree branch but it doesnt seem to have helped, humph!
Will investigate a bit further when I can jam it in to the schedule.

My engine is due an oil change about now as it goes. I had all the breathers off a few weeks ago when I changed the off side exhaust manifold gasket. Due to being nearly new I found them all to be as clean as a whistle. I have smelt the odd wiff of oil every now and then though but not found any anywhere?
The oil filter housing on my last omega used to weap a bit, is it recomended to stick with the little internal filter and housing or convert to the canister type filter?
Also what oil is recomended. Sorry I know its most likely on here somewhere but the puters dead at the mo and navigating around on my phone is hard going. The motor is on 130k.
I don't do many short journeys. 25 miles to work down the lanes. I try n save fuel when commuting but at least once a week I'm late and it gets a good flogging! Most of the rest of the journeys are to far away race tracks, some with a caravan, some not. Worst case scenario is to the other side of Cumbria with the car fully loaded, huge roof box fully loaded and a ton or so of caravan groaning along behind.

« on: 19 August 2012, 00:41:25 »They only leak if basic maintenance is neglected, done right they last 100k & 10 years
So I should be good for 5-6 years at over 20k per anum and by then the car will have rusted away anyhow.
If they go prematurely with good maintenance I might have to cry or something!
I wonder if stooging around all the time like a grandad helps these things to clog up?

I will admit to having done this conversion on my last omega. At the time I was not aware of the breather problem being quite as severe as it would seem to be and just thought it was another little niggle that didn't help the situation. Once I found this out I became pretty regimental about keeping them clear.
The sole reason for fitting them was because the originals were dead, one side of the channel that retains the seal was broken away in a few places and when the covers were placed on a flat surface they were clearly bowed. The seals had been changed two months before I bought the car and they were leaking already. I had them done again and they leaked almost straight away. I changed the seals again myself with the help of a competent mechanic and obtained all parts from Vauxhall and correctly torqued but didnt hold much hope due to the state they were in. Needless to say I needed another solution.
So after getting over the shock of being quoted for new ones from Vauxhall (I think they were well over a ton per side but may be wrong) I spent an age looking for second hand ones in good condition but drew a blank. In the end I went for the metal covers out of desperation and I can see why others might do the same especially if they have not come across this and similar sites as was the case for me.
My current car had brand new covers and breathers 4 months before I bought it so hopefully I'll not be cornered like that again.
So if the breather system is different on the vectra and that is fine with the metal covers doesn't that point at the omega breather system being rather susceptible?
Sorry I've written another long and boring story!

« on: 17 August 2012, 22:52:10 »
If helicoils are fitted correctly they should be good. Most of the problematic ones I've dealt with were not seated properly in the first place. IMHO if you get a helicoil put in by your average mechanic that rarely uses these things you have a 50/50 chance of it being duff.
The little helicoils can be a right PITA sometimes and some batches are worse than others. Spark plug size ones should be fine though.
Having said that, given the choice I'd still choose a timesert/keensert or similar due to ease of use. Depends what available I guess.
The thread will need tapping out to a larger size anyway so the thread quality should be good.

My 2.5 used to do this, it got slowly worse and then the clanking rattling noise started. It would sound like bag of nuts n bolts when the clutch was disengaged so I always assumed it was a flywheel/clutch issue and something was coming loose or breaking. Never got round to looking into it as the car had other reasons why I wasn't going to be spending too long trying to fix it.

I've now got the changer working but have no major desire to mess about driving around with CD's. The top slot is still on strike so no sat nav for me.
