    The amount of time it takes to start doesnt seem too bad but the smoke @ startup is likely bad valve seals.

    Well, if it is really white smoke, that means water is getting in your cylinders, that is bad. Most likely blown headgasket. But if you look again, and it is blue(very common) that means that is it valve seals, Scooter just did this swap, you can PM him and get all the info you need. Hope I helped.

    Takes about 5 seconds, that's only due to really advanced timing. White smoke on start up, big cloud the colder it is, but is gone within 5 seconds.

    Some white smoke on start up is normal, especaily in humid conditions or if the truck hasn't been driven for a while. Free flowing exhaust or a lack of a catalytic makes it more noticable. Its just condensation.

    Not a big deal. So breath out... O.K. relaxed?

    Proabably, your Blazer is caberated, the "mini" is Fuel.Injected.. Sooo, they need different starting routines.

    With F.I., just turn the ign. key, let the computer do the work. (don't touch the excellerator)

    With a carbed engine, Pump it once, hold the pedal at 1/4 throttle and crank. Did it start? No- try again. It'll take alittle while to figure out what you Blazer likes, but don't go nuts with the pedal or you will flood it. To clear a flooded engine, hold the pedal wide-open and crank for 30 sec. and again w/o moveing your foot. Than retry the normal starting procedure.

    "White" smoke is most likly <font color=blue>blue</font color=blue> smoke and is really not a big deal on start up. (probably just valve stem seals)

    My '87 was hard to start. Took the starter &amp; battery out had them checked, both were bad. Replaced both, starts MUCH faster now. Mechanic friend thinks my fuel pump may be bleeding back, as it doesn't start as fast cold as when warm! I have no smoke on start-up though...... sounds like a head gasket or cracked head is seeping. Are you adding any water? If so, get the back end of vehicle higher than the front end, take the radiator cap off, if you see bubbles, you have problems!

    1 ton '87 Chevy SWB in the making!

    valve seals it takes a long time for the oil to seap through the seal 5 min is not long enough for the oil to drip into the cylinder. 5 hours yes

    So white smoke is the oil burnt when its seeped into the cylinder? Is it hard to fix valve seals?

    For the long cranking problem try turning the ignition to start (without actually starting it) to let the fuel pump pressurize the lines. You will hear the fuel pump make noise and when that stops after a few seconds then start it up.

    I should just replace my heads! What kind should I get and how much would they usually run?
