Front left side engine mount

[red vtec]

Just getting ready to pull the engine. What size is the bolt on the engine mount down by the manifold? I don’t want to round it off. It’s ages since I did the others and I don’t have the parts book with me. The WS manual does not give the size. It’s an early 88 Steven’s. Thanks

According to my parts list it is an M12 x 100 bolt so the spanner size should be 19 mm.

@fjmuurling thanks for reply.  It’s the tightest nut known to mankind.

From memory, you can't get a 1/2" socket on the top, either. Spanners only.

Definitely 19mm.  The nut will probably move before the bolt.  Use physics - increase the spanner length by whatever means.  If necessary I have metal tubing that will do this.  You can wedge a 19mm ring on the bolt if it turns.

And, if you have a n Alunox manifold, you lift the engine in and out with the bolt still in place, taking note of Rubik’s heat shield assembly.

Ive managed to get spanner’s on both sides, I did have a ratchet on the top with a long extension and wobble joint. I used to have a metal tube for slipping over spanner’s, not sure where it is. Think I’ll have to work it back and forth with plenty of lube ( not the first time  )

Is the 13mm bolt into a captive nut? Thanks 

[Sparky]

If you mean the M8s holding the mounting to the chassis, they are nut and bolt - not captive.

@Sparky thanks, if I remove these I can then lift the engine out? The big 19mm won’t move for live or money. 

[Sparky]

Correct.

On my '85 TE, that motor mount bolt was captive even with the OEM manifold. I had hoped my Alunox would allow extraction, but no.
