advice needed......lurch has a headache.....

i wish to spend heaps.......

but simply cant afford to.......





do you know the safe temp. range and the danger range for a Td5.......?

i have found that when ive been pushing lurch hard in top gear up a hill.....for example......
i get a burning smell start to come inside the cabin.......

i just put it down to an oily section of the exhaust getting hotter than normal and burning off the oil.......

i back off the go pedal to allow things a chance to cool off......


the moral of the story is......things are getting hotter than they should......and i would like to know how hot.......

so an egt guage is what i need to avoid any damage......i may have just been lucky so far......

Sorry as this may seem blunt, but, WhyTF do you want to bake the manifold, DO THE BLOODY MOD AND PUT IT BACK TOGETHER:mad:

OK

Baz.

to chuck it out there...


because theres been one case that I know of where the removal of the webbing has been a factor that has lead to the manifold cracking.

it might not have been the only factor and maybe baking it would have helped... it cant hurt it.

I have been folowing this one with great interest, and I tend to agree with blknight.
If you weld cast iron you must heat it up nice and hot before you start welding, otherwise bad things can happen. Bad things may not happen but you are putting more chances on the negative side. Cast iron while strong can be fickle. So by baking it there is more chance that things will go the way you want, and not the other way.

That is just my 2cents worth.

There are a few threads on the fitting pro's and con's of EGT. My take is that generally the upper limit is 750c and things go wrong.

OK went out on the weekend to set up the manifold to drill and elongate. I measured the existing holes and note that they are 8.87mm. Defiantly smaller than 9mm as 9mm drill will not pass through and there’s slop in the 8.5mm bit. Veinier gives 8.87

I’ve got a 10mm end mill so I was planning to use this and upgrade to 300TDI studs which I understand are 10mm

Given the above, will a 10mm elongation be too tight for the 10mm studs. With the 8.97mm current diameter I was thinking of just elongating the existing holes.

I’m probably a little pedantic but would appreciate any comments.

how much to machine the exhaust manifold......


from those that have done this.......

I was quoted $80

thats what i got quoted........i thought it was a bit much.......

but he said they are hard to hold so he can machine them.......


if theres a bit of mucking around to set them up.....then i guess thats a fair enough reason........
