Z22SE manifold heat shield removal issue

identiti66

One of the nuts/studs that keeps the manifold heat shield on it stuck fast..it's the top one, drivers side.. has 2 nuts on it, 1 to hold a bracket on, 1 to hold the manifold on.

Can get the first nut off but the second one is now partially rounded and stuck fast.

I could really do with removing the nut and stud as I have new ones ready to go on (I need to remove the heat shield to check whether the manifold is cracked - the car doesn't behave like it is (performance and mpg are 'normal') but there's a noise in the manifold area that sounds like a blow to me.

Any ideas how to get the offending article out? I have no access to specialist tools.

You're not having much luck with the car, that's part of the fun of doing it yourself

How about vise grips to remove the rounded nut
(Just in case you don't know what they look like)

Either that or try to hammer a smaller socket onto the rounded nut

Rounded? Did u use the correct size socket or did u use a cheap spanner? As above and also try some WD40. When i took off my heat shield to change the water pump the middle bolt snapped and half of it is still in the manifold - i just left it.

It's niggly stuff tbh (well, yesterdays spark plug debacle was a bit more serious but turned out ok) and tools for this job were a Snap-On 13mm ratchet/socket combo and Halfords Professional spanner.

The thing is stuck..... I loaded it up with WD40 penetrating gear for our first battle and yesterday I hit it with GT85.

I got a pair of stilsons on it yesterday, an old boy mechanic I knew some 25 years ago swore by them for stuck stuff like this.. but they started to slip so I stopped..

We have mole grips but the stilsons teeth are 'sharper' so I dunno if they'd be any better - worth a whirl though I guess..It's not completely rounded (yet) but it's getting there.

I could possibly Dremel it off but then I still have stud that I want out...
