Hi Everyone, for those of you who are running a LCB manifold, can you tell me if you can fit the manifold to the motor before putting the motor back in the car or do you have to fit it with motor already back in. I`m just concerned that if I try and fit it with motor out, I might have to take it off again if it is in the way. I realise I will probably have to leave off the small 2 into 1 section at the end of the manifold.

regards

Jethro

Depends on the brand, but I usually leave them off and then fit after putting the engine in.

Hi GT, from memory I think it is a Maniflow

Jethro

Yeah, leave them off for engine fitting, but put them on before putting the engine mount bolts in. I find sliding the engine forward about 10 to 15 mm lets you fit them fairly easy.

I always fit mine after the engine goes in, and remove it before the engine comes out.

I find it is easier to remove the exhaust pipe Y piece after I have pulled the manifold off the head because the separate branches are easier to wiggle out of the Y piece than trying to wiggle the Y piece off the two branches, if you follow my meaning.

Mine is the Maniflow one.

cheers
michael

It was a pleasure ausmini. I'll miss all you misfits and reprobates

when I fit it after engine is in, will it be awkward for me to reconnect gearbox up again and insertion of roll pin or do I do gearbox linkage first then manifold???

Jethro

Maybe slip the bolt in first, I usually do it later though, so I can rock the engine a bit. Just don't tighten the manifold to the head until you have the steady bolt in. You won't have any problems with the roll pin.

As I am putting on a new HS6 carby, I take it I would leave that off too and do everything after engine is in ??

Jethro

Yep

maniflow, very easy to install after the motor is installed

i use a maniflow LCB and an RC40, and i can have them off in 30 mins and back on in about 45mins.

Install double set first, install centre branch, get under install the join, then the pipe, then the muffler and your done. Very very easy.

It might be worth quickly putting the manifold on the engine first to make sure everything fits. I'd bolt it on (just lightly), and adjust the mount where it attaches to the gearbox (since these are usually simple pieces of metal that you bend to the right shape - much easier to do if you're not under the car). Then just take it off, put the engine back in the car, put it back on.

I say this because the LCB manifolds sometimes don't fit perfectly - I had to grind one of the bolt holes out a little on mine, and I've heard some people have had clearance issues with the inlet before.

GT, Mickmini, Drexxle, as usual, many thanks.

Jethro

it would be a good idea to install the branch first and check for fit

you can use something like cereal box for a gasket just to check clearances. or throw away the gasket and put a new one on. Id go the cereal box, you can check your clearances easier that way.

I had a slight difference in the inlet from the branch, as the bolts cover both sides they need to be even so that you dont get a leak in either the exhaust or worse a leak in the inlet.

sometimes they are slightly bent, but i had no issues with that, perfect fit and almost perfect fit on the heated inlet i bought to match the LCB

I did something simlar but I used Grease. As I had new Inlet manifold and LCB I want to know how they matched up. Smeared the grease on (in this pic) of the Inlet manifold and clamped it on.
Yes the manifold can have a little bit taken off it so the ports match

But myself to put a engine in I do not have Exhaust or Inlet manifolds and no Radiator or Alternator...I like as much room as I can swing the engine around

Looks like I'm the odd one out here....I have always had problems separating LCB's once they've been in use for a while - those Y pieces are a $%^# to move. When the engine is in the car you can't get the LCB with Y piece down behind the engine (maybe OK from below with a hoist?) so I sit the LCB (with Y attached) in the engine bay, but tucked over by the master cylinders, drop the engine in, then move it into place. Much easier and less swearing than separating the LCB.
