Don't know if it applies to your diesel but most later gas engined vehicles have a 'cold start' valve that supplies additional fuel to the fuel/air mix along with boosting the idle speed until some warming of the engine is sensed.

If the smoke is white, or steam it is water. you might have cracked the head or warped it. Did you get it looked at before you put the new gasket on? If the smoke is black then it is oil. Do a compression check and see if you don't have a bad cylinder. They should all be about the same give or take 5 lbs.

well,when you turn off the rotary it leaves oil and gas.so when you start it up, it burns off the oil you left causeing blueish smoke. same problem with flooding,when you drive short distance , warmup incorrectly or if use synthetic oil.to fix the cause of flooding(i have the same vehicle and problems)let it warm up for at least 15 min.there is also a fuel pump wire next to the fuse box located above the brake pedal.then you tap a switch from the fuel pump to your interior.the reoson being is so whenever you come to a stop to park flip the swith.that allows the rotar to burn the fuel left in the pump witch will make your rx7 to stutter out and die.when you start it back up ,flip the swicth back on and it will take an extra second for it to crank over.1 more thing,check your oil every 2-3 fills on gas and change oil every 2000 miles.also redline it at least one a week. i hope i just solved your problem because i love my 87 non turbo and know how you feel.if you want to look at cheap aftermarket parts for rx7 then go to srmotorsports.com/rx7guru.com is a guy that test parts to tell people wats good and cheap for rx7s.i would recomend roll cage and 5 point harness-seats.good luck with your rx7 bro

you definitley seem to be getting oil in your combustiion chamber, pull your spark plugs and see if they are coverd in oil. if so your valve seals are bad, if not your piston rings are bad. As far as the kncking noise its hard to tell though a description, id have to hear it, but ill go out on a limb and say its in relation to the leak it could be a piston or valve knock. The garage heard the noise, ididnt so i hope i could help.
