Hi, the inlet manifold bolt - one of the corner ones securing the manifold to the engine block is not biting and will not tighten. It's been like this a while but all the other bolts are correctly torqued. Would this help account for my really high fuel comsumption and any ideas how I can fix it? The bolt itself is OK.

Cheers
Chris

helicoil to fix, dose the old bolt undo OK?

Great, thanks. Yes the old bot comes out OK.

Is it the inlet manifold to sandwich plate thats duff, if it is I would get a second hand sandwich plate just in case the brass insert has lifted a little which might cause an air leak

No, it's the aluminium manifold that sits on top. The bolt goes through the sandwich plate into the engine block.

Ok, some clarification needed.
Plenum

Inlet manifold

Plastic Inlet wedge

Block.

If the inlet manifold bolt is turning, it's the thread in the brass thread set in the plastic inlet wedge that is spinning round.

...?

Ah, its the Inlet manifold. That's much better than I hoped then, I did not realise it screwed into the plastic inlet wedge - that's much easier to fix then - I'll get another one.

Cheers!

[chrisdb]

Scrap that, sorry. Just looked at the drawings in the EPC to remind myself as it's been a little while. It's the corner screw of the plastic inlet wedge which is spinning. So... back to the Helicoil?

Cheers

you'll not get a helicoil in there - its a brass insert which is moulded into the nylon.

New inlet wedge required. Often called a "divider" on here

Sorry I am unsure after reading which thread has stripped.
Is it one of the bolts the Divider/Sandwich Plate/ Inlet Plate to the heads or one of the six bolts that bolts the Inlet Manifold to the Inlet Plate?

If it one of the bolts that go into the heads, yes you can use a helicoil

yes of course

Sorry, forgot to post the update Got a set from Machine amrt - it was their own make of Helicoil, brand name Clarke - it was cheaper than the Heliocoil but worked brilliantly.

Cheers all
