I have a 1993 honda prelude si h23

on a hott day if i use my car all day smoke will come out the tailpipe. it looks like white steam. i think its the water. and yea the water in the radiator gets low.

but there is no water in the oil i check and this problem only happened 3 times in the last 2 months. There was a ton of smoke though. and every time it happened when i used reverse on my 5speed. when i shifted to first the smoke stoped

any ideas

is it the water pump or like the head gasket?

 

Hi dear, well maybe (im not sure) but i had 2 times this problem ... 1 with my 3th gen lude and 2 with my ex-gf integra you may have 2 things,

1: Oil getting in your spark plugs (white, clean smoke)
2: Water Pump (white hot very hot smoke)
But in the way that you're telling (your wather going low) you may check your hoses or even make sure if it's really your water pump, when i had the smoke coming from under my car, it was a little hose that my mechanic charged me $30.00 to replace ,, (i was so paranoid thinking that i was going to spend 200 250 for the whater pump replacement , LOL

water LOL

 

It's a bad head gasket. The engine is not hot enough at start-up to burn coolant off the block (as in an external leak.)

 

overheated lately? shrink the head gasket and pow -- white smoke from water
