Is 2mm aluminium man-enough for an EGR blanking plate or swirl plate ?
I was planning to clean out my EGR but, given the awkwardness of getting some of the bolts off, I decided to blank the EGR first, to confirm that this cures the problem.
(Problem: Very low power from idle to about 2000 rpm, then power kicks in and is normal; worst with cold engine; no fault codes generated).
I made two blanking plates from 2mm aluminium, and fitted them in place of the pipe, as shown, using M8 x 16mm bolts instead of M8 x 25mm.
This has cured the problem, so a blocked or damaged EGR is the cause (probably just blocked after 109,000 miles without a clean !).
If I either
a) leave the blanking plates as they are, or
b) clean the EGR; refit the pipe; and refit one of the blanking plates but with extra holes drilled in it to convert it into a swirl plate,
then is 2mm aluminium enough or will it suffer due to heat or corrosion ?
Or should I make a new plate out of stainless steel ?
