Hi all,

‘96 1275 SPi

I’m trying to get inlet manifold out but really struggling to get these union bolt things off for the past few days. They won’t budge at all. I’ve tried some wd40, elbow grease, more wd40 and more elbow grease.

Is there a knack to this as I feel I’m doing something wrong?

If I can’t get them off, could I just disconnect the hoses off further back or is this likely to make a right mess?

Cheers!

Should have said, I’ve been using two spanners. One to hold the small one in place and the other to try and turn the big one anti-clockwise!

Whatever you disconnect, you’ll get fuel coming out. Just have cloths ready. I’ve never disconnected those fixings and instead have always taken the rubber pipes off further back. Never liked the risk of messing the pipes up, they’re no longer available.

I block the rubber pipes up with drill bits and clamp.

I always disconnect at the rubber hoses. I have seen two SPi where the pipe was kinked just after the nut were the pipe twisted with the nut being opened.

I too have seen many cars with twisted pipes, nevertheless, they can be disconnected, just make sure the bracket next to the rubber fuelhoses is off. (that will allow the pipe to move and should stop it from twisting) if you need anything for your injection housing i've got some spares.

Might be an opportunity to replace the hoses too, if they're original? I didn't have any problem disconnecting at the fuel lines, using two spanners as you suggest. iirc there's an o ring seal to keep a look out for if you do detach the fuel lines from the injector body. Good luck.

Thanks all,

A bit more elbow grease tonight got one of them off but the other still won’t move.

Perhaps also helped that I bought a size 15 spanner which fits better so using a 15 and a 17 together.

I’ve sprayed more wd40 on it this evening and ordered some hose clamps which arrive tomorrow so if I can’t get the other off tomorrow then I’ll take that one off at the hose. Maybe when I’ve got the throttle body on the bench I’ll be able to get at it from some different angles!

Will let you know what happens (or if I need some spares!)

My own 2 cents....
Don’t use WD40 it’s crap at releasing rusting or stuck stuff(it’s fish oil base).
Use PlusGas and you’ll find most of these type of tasks easier.

Alright just ordered some of that from amazon so that’ll arrive tomorrow and I’ll give some of that a go!

[MatthewsDad]

Might take a few days / applications to work, but it is good stuff.

Huzzah!

I know its a bit late now, however heat does help. Obviously any flames are out of the question   However pouring boiling water over helps a little.

[slayerofcows]

No doubt this ain’t gonna be the last of my seized up bolts and screws so all advice welcome!

[slayerofcows]

Also a bit late this but I’m sure it too will serve useful in time to come.

I always use a flare nut spanner and an open ended spanne.
