Exhaust Manifold Woes
« on: 21 November 2008, 08:20:41 »
I was traveling up a hill with speed humps the other week and had to dodge some idiot coming the opposite way who was speeding forcing me to bounce awkwardly on a speed hump, before asked I was doing around 15mph if that and had to go to the centre of the road as cars were parked to the left of me.

My car now drives like a crap and I discovered yesterday the manifold is ticking when cold >:(

What are the chances of more damage having occurred.

I am going to be removing the manifold tomorrow to get a better look.

More work  :(

I think it did cos there was an almighty thud >:( at the time I stopped and had a brief look under the car but had to continue as was late for work.

The car though once warmed up drives nice.

Well I had a look at the exhaust today and the manifold, the exhaust still looks solid and I checked all the joins and they look to be leak free. Damn it was cold  :(

The Manifold however I found a loose bolt in the top row and missing  2 bolts in the lower row which annoyed me fortunately no snapped studs.

I had to fit a new bolt in the one which was loose, used my tap & die tool to clean and check the thread in the head, bolt tightened in spot on.

There were 2 lower bolts which i managed to put new bolts in as they were loose but I dont hold much hope for them at the moment as I had a garage do some work on the car a while back when they did the HG and I think they may have mucked the threads up good and proper.

Still moment of truth will be in the morning with a cold start.

My plans for the future are to totally remove the manifold and retap all the threads and fit a new set of bolts.

Cheers  :y its annoying as I have done the manifold a few times now what with failing gaskets and bolts, I had it spot on before taking to a garage and knocking the underside of the car.

Last time I removed the manaifold it was refitted and was spot on all torqued correctly, now regretting letting a garage get there mits on my omega and going near the speed humps always the way a short can cause problems ::).

Just need to find a good dry, warm day and crack on with it.
