All - per the above, I began looking for e30 expertise in Indianapolis: I've now tried Merkle (dissatisfied/no-help), Mikar (great guys; too busy) - and it looks like I'm relegated to Reggies...who is well respected by the racers, but I suspect will be VERY costly as a "boutique shop"... Does anyone have any favorite BMW service experts in the greater Indianapolis area? It&by moapys - Technical Forum
Well - the latest...: I cleared the 1222 code - it was a holdover from past vacuum noodling - last several starts/trips resulted in no (eg 1444) code. Alas, so much for that red herring... I did re-adjust the valves, stone cold, they were a bit tight, so put them back to a solid .010 - and checked both ends of the rockers for .01 / .007 consistency...all good. I even checed the 02 sensor for goby moapys - Technical Forum
Quick update: I struck-out on the smoke test (having made a jury-rigged bidge for past E46 troubleshooting), as it indicated no evident errant wisps. I finally did a stomp test - was late in considering that, having no CEL illuminated - to see if it reinforced the vacuum thesis; TADA it yielded 1-2-2-2 (Lambda 1) code: This still can be sensors, vacuum, O2, etc; so I guess I am still back to cby moapys - Technical Forum
Thanks for the inputs, gents; and I had planned to let things settle in (let the lapped valves seat a bit more, etc) and then do a re-adjust. I'm getting a bit of feedback from other boards about insidious leaks around the "bitch tube" - which seemed to re-seat fine after the zips were cut - e.g. a poor seal around it. I'll do additional sleuthing, re-spray test lines/couplby moapys - Technical Forum
Folks, I'm at the end of my wrenching-skills, following a post-belt-break valve-job. The vehicle is an E30'vert with the M20B25 (non-eta) engine. I had a few valves break, and couple bent - I replaced bad ones from a donor head, all were 'roll-tested' for straightness, dip cleaned and polished - and finally lapped in-port upon re-installing. Yet; I have a "lumpy&quoby moapys - Technical Forum
