Thought some people might like to know about a problem I've encountered.
Just had a fault repaired on my car yesterday, been hearing something I can only describe as an intermittent hissing noise when I started the car cold/warm (not near normal running temperature). A friend of mine thought it might be the manifold gasket.
Took it to my local Vauxhall garage and they identified this as two cracked manifold bolts. Because they had cracked more or less inside the head, they stated it might be a big job to remove them as the head may have to be sent to an engineering firm for drilling £1000ish quoted. A common fault with vauxhalls apparently :?:
Fortunately I get on really well with one of the mechanics who's worked there for ages, he said he'd try and remove the sheered bolts with the head in situ.
Decided to sit and wait @ the dealers for the outcome, after a couple of hours of what looked like hard work, he eventually managed to remove them, no damage was done either, what a relief !. I don't like heads being taken off any engine, as it never seems to run the same afterwards. Also I didn't know this until just before he started, but the work was covered by the warrantie so I'm not out of pocket either .
This may sound a bit obvious but, got in the car after it had been fixed and found she's improved on performance , it must have been steadily getting worse over a long period of time as I never noticed the power drop :shock: .
