TVR - Refitting Manifolds

Refitting Manifolds

Having gone through the pains of removing the manifolds to remove the precats, I was not looking forwards to the task of fitting them back on.  It was an absolute nightmare of a task to get them off the engine, putting them back on would surely be harder?

Nope, all done in a single afternoon, compared with the 2 weekends I spent taking them off, this was amazing.  And all due to 2 little pieces of advice I received.
1.  Use ARP fasteners.  These are a direct replacement for the original bolts, but have a smaller head size making it much easier to get a wrench on them in the tight confines of the engine bay.


2.  Slot the bottom bolt holes in the manifolds.  Absolute genius!  This allows to have the gaskets held in place and manifold will locate straight onto them for easy fixing of the remainder of the bolts.  Only item to remember here was on the drivers side manifold the confines are really tight.  So you need to tighten the bolts well into the engine before putting the manifold in place or it will get stuck on the bolts.  One it is in place you can back the bolts out and place the manifold right onto the easily.


A few hours in all, but no longer am I afraid of doing this job again should the need every arise.  Coming back together nicely now.
