the right side , tunnel port can clog easy. |
bottom plugs removed to clean, injector dillings. then plugged with screws later. I'd tap them with 10-32 screws or metric 4 or 5mm screws |
the first photo ever posted of cleaning the actual injector hole for EGR Thanks to Mr. Zukitrek. |
the EGR transfer post can be seen here. this gets EGR working just off IDLE, it's not available at idle at all. The bottom flange hole is just for drillings when manufactured, its blocked by the gasket, 6pm. flange. |
Welsh plug drilled, to aid cleaning, not sure which mm size it is but could be removed and replaced.15mm? or so.... |
nasty TB and see EGR ported nipple at 6pm |
