Hi

I'm trying to reinstall the bolt on the side of the block that holds the coolant to stat pipe in, apart from the gnashing of teeth, swearing, spitting, I thought i had finally got the pipe dispstick and engine lift plate lined up, confirmed by my illuminated mirror, and running a small screwsdriver into it to roughly aligh it all. I started running the bolt in and felt it catch, but then it started going in at an angle, leaning towards the bulkhead, I carefully kept going with a 10mm spanner, ready to stop if it felt to be suddently getting tight, which it started doing. I removed the bolt and it looked ok, didn't look as if it was cross threading.


Tried again and the same thing happened. Has anyone else found this issue whilst putting the bolt back in?

God what a nightmare that thing is!

At the risk of threading it I slowly ran it in, no other choice had to risk it, it seemed to have that feeling of not being too happy as it was going in, but managed to get it tight and the pipe feels secure now. I think it's now time to call the guys with the straightjackets!

It does go in at a downward angle (head pointing towards the wheel arch)

It was leaning slightly to the right towards bulkhead, know what you mean about it going in at an upward angle as well though.

Suggest you run the bolt in with nothing inplace to ensure the thread isnt damaged that way the bolt should clean things up.

I opened the hole on the lifting eye with a 10mm drill which made the entire process much easier as you then have some tolerance getting the bolt correctly aligned and it all goes back tight and in place.

I doudt if any omega is ever going to have the lifting plates used now given the age of even the youngest of them

The lifting eye almost fell back out of the way, as if the bottom bolt holding it on was loose. I don't knowwhat happened with reinserting the bolt, it wasn't happy, and was tight the whole way in, but it's tight so fingers crossed.

Perhaps not, but if you don't refit it you should add an equivalent spacer.

Agree with not leaving the lifting eye out of the puzzle ,although I found opening the hole in it made alignment alot easier...almost a simple job

I don't see what all the fuss is about.. It is almost as easy to fit as the #6 spark plug

Reducing the end of the bolt to the thread minor diameter is very helpful when struggling to align lots of parts at odd angles.


Like this:





The non-threaded self aligns, so all you need to do is start the thread. Opening up the lifting eye is also very helpful.


My car ran for years without the bolt, as someone had broken off half the boss it screws into.

I noticed the end of the bolt is tapered right down through the threads to the end. It's not got that end section without threads though, just tapered.

No, you have to do that yourself.


An alternative would be to loosely screw a longer length of studding into the hole, and use a nut.

My Cortina years ago had loads of screws/bolts like this

Used to be a standard engineering thing in the good old days. The quality of some modern forged bolts is shocking.

Interesting, as none of the Fords I've had anything to do with did. I'd have been happier if they had fasteners that weren't guaranteed to round off or snap, which was also true of all the other European stuff we worked on. That was the big improvement with Japanese cars; although the bodies rusted just as badly, dismantling the mechanical parts was never an issue.
