I just got my 87 420sel on the road after fixing a bunch of little things. Some of you may remember that I bought this as a parts car from a guy that said that the tranny was frozen. Fixed a leaking line near the radiator and it's been good to go ever since. Now for the first problem. The car runs good, no misses, good idle and seems to get pretty good mpg. I've only driven it about 400 miles since I got it. I replaced the plugs, cap, and rotor. Today I took it out for a little exercise and pushed it up to about 80 and had to stop fpr a red light. I noticed what looked to be blue smoke from the exhaust. Crap!! The car ran rough for a few seconds as I pulled away from the light and left a big cloud of smoke. I continued to drive normally and didn't see any more smoke. So I decided to push it again. The same cloud of smoke appeared again when I came to a stop and then pulled away. It seems to only do this after hard acceleration. I didn't notice any smoke while accelerating, only after slowing down to stop. I'm not getting any smoke on startup. Also, I had the wife drive while I followed in the other car and didn't see any smoke during normal driving. Any ideas?? The only issue I've found with the engine is there is a clicking that seems to be on the drivers side that comes and goes at will. Cam oilers maybe?? Could these two be related?? Thanks guys.
