sierraman Posted May 23, 2015 Share Posted May 23, 2015 Contemplating replacing the exhaust manifold as its blowing. Obviously this is going to involve undoing the studs that go in the head, any tips here to avoid a sheared stud and secondly any tips at the other end for shifting rusted up exhaust bolts?

Parky Posted May 23, 2015 Share Posted May 23, 2015 Plusgas, lots of. Apply liberally several hours before attempting to remove anything and that might save you a load of hassle later. If accessible I try and wire brush as much of the old rust off first so the Plusgas doesn't have so much to try and penetrate. Might help with the rusted exhaust bolts too but in more extreme cases you might be looking at dusting off that old blowtorch in the shed in order to apply maximum heat. Obviously ensuring you aren't using naked flames near petrol tanks and hoses! Good luck! Link to comment Share on other sites More sharing options...
twosmoke300 Posted May 23, 2015 Share Posted May 23, 2015 It's a ford so everything will be seized/ rusted solid . Ford could make plastic rust I'm sure . Guess who is bitter cos he had to work this morning on a fucking transit cos the prop coupling was seized on solid !

sierraman Posted May 23, 2015 Author Share Posted May 23, 2015 Might farm it out to the garage then. I hate doing anything to do with exhausts, I've took a manifold off before but it was years ago and it went fine plus access was easy and I wasn't doing it at the side of the road it was in a garage.

castros_bro Posted May 24, 2015 Share Posted May 24, 2015 Hi, wot is the engine? Zetec SE? I have one I dismantled earlier so could send photos as you cant.see bugger all when its still in situ. Worst was the rusted manifold to flexy coupling at a silly angle in a cramped space. put a picture of 6 spanners here Link to comment Share on other sites More sharing options...
sierraman Posted May 24, 2015 Author Share Posted May 24, 2015 Yes the 1.6 Zetec SE. I can get the actual replacement for the flexi for £30 but the garage said labour would be negligible between replacing the manifold and grafting a new flex on. If a stud shears then its head off time i imagine given the access? At a guess I'd say it looks like an hour or so labour if you had access to a lift so might get the garage to have a look. I hate giving easy jobs away but when it's financially not worth tackling laid on your back on the drive you have to. Link to comment Share on other sites More sharing options...
The Reverend Bluejeans Posted May 24, 2015 Share Posted May 24, 2015 I did one not long ago. One of the easiest manifolds ever, did the swap in 1.5 hours start to finish. If the nuts are seized the whole stud unwinds = so wind it back in again. Aftermarket ones don't last that long so it's a toss up between that and the possible/probable arse rapeage by Ford. You do the manifold the head bolts from up top and are surprisingly easy to get to once you overcome the fear of doing it. steveo3002 and junkyarddog 2 Link to comment Share on other sites More sharing options...
doobietoo Posted May 24, 2015 Share Posted May 24, 2015 Did the Golf exhaust today strangely enough as I had a broken stud. plus gassed it then took it for a short drive then while it was still warm re plus gassed it then loosened the other nuts just half a turn waited for it to cool down a bit then wound them all off.This left me with the broken stud. Luckily it was long enough to put two nuts onto which I tightened against each other and wound the stud out... easy. replaced the broken stud and bolted it all together again. took me an hour ....

castros_bro Posted May 24, 2015 Share Posted May 24, 2015 Has yours got the cat between the ex-manifold and the fexi, where the downpipe should be? if so.then the cat mounting to engine brackets~bolts will be a rusty pain. Link to comment Share on other sites More sharing options...
sierraman Posted May 24, 2015 Author Share Posted May 24, 2015 The ford ones are I believe £95. The aftermarket ones are £45. Since I last posted, I've been out and had a look, whipped the heat shield off, sprayed on loads of Plusgas onto the threads, doesn't look too bad access now I've faced the beast. Most difficult bit looks the Cat/manifold joint as the bolts here looked rusted/seized to fuck, again a blast of Plusgas and hopefully it will start to release. In any case if the bolts shear I can just put a M15 bolt through. Might give it a go now... I'll post when I'm giving it a go! Link to comment Share on other sites More sharing options...
The Reverend Bluejeans Posted May 24, 2015 Share Posted May 24, 2015 £95? Buy the Ford one. Aftermarket ones last about a year. Link to comment Share on other sites More sharing options...

sierraman Posted May 12, 2018 Author Share Posted May 12, 2018 I've got a good one if you want,I took off the black one. Took me all of 20 minutes to swap it. Not that dear new, £45-50 or so. Link to comment Share on other sites More sharing options...
steveo3002 Posted May 12, 2018 Share Posted May 12, 2018 ordered already but cheers..so no snappage on the bolts then? and it wiggles out with everything in situ? did the o2 sensor reuse? Link to comment Share on other sites More sharing options...
sierraman Posted May 12, 2018 Author Share Posted May 12, 2018 Yes, 22mm open end spanner removed it. If it won't budge I've got one you can have. 4 15mm nuts then a central 13mm bolt you might miss. Some 17mm nuts underneath. You might need the grinder on those though. Link to comment Share on other sites More sharing options...

sierraman Posted May 12, 2018 Author Share Posted May 12, 2018 Some nuts from tool station probably do. Mine came out no problems but I'd greased them prior to installing them. Link to comment Share on other sites More sharing options...
