L200 EGR pipe problem
Discussion
Excuse my lack of technical terminology here, I will endeavour to explain as basic as I can.
I’m having this recurring issue where I can’t tighten sufficiently the first section of pipe attached to the manifold that connects to the EGR cooler without stripping the thread and so the exhaust gasses are pushing through and demolishing the gasket.
My question is is there a way to permanently affix each part together?
The parts themselves are the coolant outlet and as i said the link pipe between the aforementioned and the EGR cooler.

I suspect you may be either over-tightening or have a defective gasket.
Find out what the ACTUAL torque required is, as a first step, then have a closer look at the metal faces for distortion/damage and then any gaskets/seal in there.
It’s gone beyond the reason why now, it didn’t initially tighten to a point where there was resistance and the opposing thread slug tightened up solid.Find out what the ACTUAL torque required is, as a first step, then have a closer look at the metal faces for distortion/damage and then any gaskets/seal in there.
Now its a case of how can i affix the two parts together permanently without buying yet another replacement?
Piece 1 has two threaded slugs. Piece 2 has two holes for the slugs to slot into with a gasket in between 1 & 2. They are then fixed together with a nut on each slug. Slug A spins continuously when tightening the nut whilst slug B and its nut is fully tight.
Slug A’s orrifice no longer has thread. I haven’t excessively tightened it beyond a clear limit of resistance yet it continues to spin without resistance.
Can the two pieces be fixed together without creating further damage for example welding?

I think by 'slug's orifice' he means the threaded hole into which the stud screws.
If the stud is spinning, the next question is whether it's the thread on the stud or the thread in the hole which has stripped. So that needs to come out... try to unscrew it whilst simultaneously applying some withdrawing force.
Then post pics.
Exactly this. The stud is out of the hole and in tact with no damage to the thread so then I assume it will be the thread in the hole that is compromised?

Happy so far. Conscious I have ignored requests for photos; I’m not able to for a few weeks so just trying to get ahead with solutions and booking in with the appropriate people.
What you say makes the most sense and sounds exactly the same as your issue. I can and have previously removed the damaged part so that shouldn’t be a problem to send off when I’m in a position to do so.
