Gap between manifolds and chassis rails ?

[Mr Plow]

Hi All

As the titles says really.

What should the gap be between manifolds and the chassis rails, I can't remember what the gap looked like when I fitted the engine mounts. They look OK, but the gap isn't very big and the powder coating is bubbling.

When I fit the new manifolds I'll be tidying up the chassis, just wondering if I need to do the engine mounts at the same time?

Cheers

Several owners including myself have wrapped the upper rail. Easy to do with the manifolds off, not sure if it can be done with them in place. If you do wrap it is important to first cover the rails with stickyback foil then wrap with silvered waterproof wrapping.

Have a look at this thread. There is a pic of a typical gap between manifold and chassis rail.

Also some detail of how to wrap the chassis rail to protect it.

As an alternative I've prepped & painted mine with high temp paint as the engine was out recently. Done 500 miles so far & all looks unchanged....




P.S. the gap is very small

I replaced my engine mounts and you should be looking at about 10mm for the gap,,loosen bolts lift engine a tad and re tighten, should give the desired result.

Thanks all

Approx. 10mm is the gap I have, so all looks good.

I"ll definitely wrap the chassis rails before putting the manifolds back on.

As you can see in the pictures which are 3 1/2 years old, no heat resisitant wrap between manifold and chassis, I have checked them last month whilst cleaning the chassis, with no flaking present, so if powdercoat is of good quality then no heat reflector is required, alas the wishbone bushes are susceptible to the heat unfortunately.
