Switched to Silca HU100 wafer kits after two batches of oversized 3s from a discount vendor bound up Opel ignitions. I mic every pack now and test with a 0.6 mm feeler; anything that drags gets binned, @MarcoV. If you’re stuck after-hours, cannibalize wafers from OE scrap cores — they’re way more consistent.

@lindsey_b87 > stuck after-hours, cannibalize wafers from OE scrap cores — they’re way more consistent… Same here — before loading HU100 stacks I lightly bevel the blank’s lead-in with a 600–1000 grit stone and insert while holding the plug about 10° CCW; it stops the first-insert hang on Opel/Mini, but if it still nips, swap the springs, not just the 3s.
