Thread: advice needed......lurch has a headache.....

Just for interest unless someone knows where in OZ TD5 gaskets could be made. I did track someone years ago who was prepared to do it but then I sold the 200TDI.

Have a read of this

I’ve been reviewing the work on the TD5 manifolds and would appreciate any comments.

If you relieve the manifold by either fully removing the webbing or simply putting a “cut” through each web. My belief was this will allow the manifold to “flex” enough during expansion to prevent further stud failure?

If this is correct then is it still necessary to use larger studs?

If you use larger studs (300TDI) and you’ve relieved the webbing then is it still necessary to elongate the stud holes in the manifold? Surely relieving the webbing and the increase in stud size would be sufficient?

Elongating the stud holes in the manifold would be bugger all extra work but my question is would the additional movement allowed by the elongation lead to gasket/seal failure in the long term?

If elongating the hole do you just elongate one side and how much.

Sorry for all the questions but it may be of interest to others as well as me.

for my money....

I would only go the oversize bolts if I had the head coming off, this is mainly because of the lack of room to accurately swing a tap handle inside the engine bay. (this is worse in a disco than a deefer)


the stud elongation that I prefer is laterally along the head only and only by about 1mm either side of center for a nominal fit. Even with the moding of the webbing I still think this is worth doing

elongate all but the bolts closest to center.

If you can find them use a cone washer under the nuts that fit to a stud that protrudes through an elongated hole.

are you refering to the spacers for the inlet manifold......?

if you get the material........you can make some using a jig saw and a die grinder or dremmel tool.......

just use an inlet manifold gasket as a template.......

Redback,

Thanks I phoned the bloke and the price seems reasonable. Said he's being getting the TD5 manifolds from all over OZ. So I said because he must be doing a good job.

BLKnight thanks never heard if "cone" washers any suggestions of a good starting place to look?

when you say cone washers.......are you referring to ones like used on cruiser hubs.......?


or like the collets found in the valve retainers but in one piece instead of two.....?

thats them, although not as agressive as collets or cruiser hub ones...

a fastner specialist like coventrys should be able to get them.
