Gaskets and the matter of a little goo.

Hi Rover Fans,

I'm about to reassemble my induction system - manifold, carburettors, etc - and was wondering if you guys could offer some advice on gasket goo. Specifically, the inlet manifold gasket and the gaskets sealing the carbs to the manifold and elbow fittings. I've got a tube of blue Hylomar - should I go crazy or just apply the gaskets clean? I'm just not sure and figured it'd be best to ask first.

Regards,
Warren
 
I've always thought it best to apply them clean for an even force across the two surfaces - I'd wait and see if anyone more experienced with the v8 has any comment first though...

Hello Warren,

You can apply Hylomar onto the corners of each cylinder head, manifold gasket and manifold, and around the coolant passages. Also smear silicon grease onto both sides of the rubber seals which sit beneath the manifold gasket. With the carburettors, gaskets and phenolic spacers, I just fit those as is. When you torque the manifold bolts, start in the middle alternating from side to side while working your way to each end. Tighten a little at a time until finally torqued to 30lbs/ft. The gasket clamps at each and are torqued to 15lbs/ft.

Hope it all goes well.. :D

Cheers Ron! A very comprehensive answer, and I'll follow it to the letter. This weekend I've got to grit-blast a few bits and pieces ready for painting in black next week, and with luck I'll be reassembling next weekend (3rd & 4th of July). My inlet manifold and rocker covers (along with the carb fittings and elbows) are back from the painter and they look bloody fantastic! I'll post a photo when they're back on the car.

After a year during which the poor old girl has been on hiatus due to family finances it's really exciting to be making progress again, I can tell you.
 
Hello Warren,

I look forward to seeing the photos... :D

It is a great feeling when progress is made with each task bringing the road test ever closer. I'll just add that with the manifold bolts, I also apply an anti seize lubricant over the bolt shaft and threads. The one that I use is made by Loctite and is made to military specifications, reventing corrosion and galling between dissimilar metals in corrosive environments exceeding 1000 degrees C. I have been using it for years, no problems with corrosion or bolt removal, even the troublesome waterpump bolts undo without any issues at all.

Yes, I have an anti-seize compound that I apply to practically everything. I forget the brand (it's not near at hand to check) but it was very expensive and a little goes a long way. It's a lovely silver-coloured sticky goo that has saved me numerous times when I've had to take things apart again. When I replaced the water pump some years back the compound was put to good use - the proof will be in the pudding the next time it comes off.

It's a small pity that the results of all this work will be hidden under a bonnet so that practically nobody ever sees it, but it has been suggested that I take the bonnet off and drive around like that in order to show off.
