Manifold studs on twin cam

[alexblack13]

Can engine go back in with manifold on?

Can't remember when I took to bits.

No...bad enough doing it with the manifolds out of the way.. Try it if you like though. just MHO

put manifolds in engine bay and hold to one side with string or something.<br abp="308">Then with manifolds in bay lower in engine with head on but no exhaust studs fitted

<br abp="309"><br abp="310">I'd hate to try to put the manifold studs in with the engine in place,it's difficult enough trying to get the manifold onto the head whilst in the engine bay..<br abp="311"><br abp="312">John

Ive had the engine out and in with the manifolds attached, depends on how easy it is remove the "Y" piece from the exhaust as opposed to dropping of the manifolds

Have fun however you do it,,, (Just been out in the sprint. Nice day here )

The engine will go in with the old cast iron exhaust manifold in place, minus the down pipe expansion box, I think, but I think not with the later double branched longer exhaust manifolds.

Indeed you cannot (on my car) get the exhaust manifolds into their approximate positions if you put the cylinder head on first. The pipes have to be in roughly the right place before you put the head on or bolt the engine in.

Even with the pipes in rough position it is difficult to get them onto the exhaust ports and on doing this last year I chose to trim my exhaust manifold studs so that there is no spare thread showing with the brass nut fully tightened. The shortened studs made it easier (possible?) to get the double Y branched pipes onto the engine.
