Title: Exhausted
Post by: Colin 009 on May 03, 2005, 22:19:11

Hi All,

Here we go exhaust has started to blow, somewhere between engine/manifold/cats. :shock:

Can't see where exactly, can just hear it. is there anything I can do to track it down.

Went in to kwik-buck to get it up on a ramp to see if I could see anything, nah just a fitter sucking air between his teeth saying "oh that'll need replacing."

Right now, pros and cons of replacing system with one without cats. Can it be done on a 1996 V8i, read somewhere it can't be done on ealier or later ones.

Confused of wembley.

Normal places really... tighten the manifold - engine bolts, and check / tighten the manifold to downpipe bolts...

I doubt it will need replacing, unless it really has rusted through or cracked.

Common place they go is the flexible coupler just after the bend - have a looksee if it's sooted up around it - looks like a big wire basket section about 9" long  :wink:

Tim's right (again) check all the usual suspects, you will often see a sooty witness mark around the leak, mine always goes at the manifold to downpipe joint, I've got 2 better manifolds waiting for the good weather.  As for the Cat I don't think you can bin it on a model as late as '96, even if you do you would want to keep the HEGO sensors.

Whoopee, have found the leak, its on the manifold to downpipe joint.

So will be givint the pipe work a good clean and then tighten the bolts.

Sometimes the clamp on that union is stretched and weak, normally prone to losen off. Its worth looking at it to make sure its in good condition, also have a look at the fitting on the downpipe, the sleeving can seperate, not to bad if it does, its a normal pipe with a two bolt flange fitting on the other end. (on my 200 anyway)

Had to tighten mine a couple of times over the last 6 months, just slacken off the clamp, and place a block of wood at the bottom of the bend, and tap it into the manifold, when you cant feel any gap between the 2 job done
