Coming home from the store tonight I decided to take the longer way and
enjoy the nice evening. I hadn't stretched my cars legs for a while so
coming up my road I accelerated normally, not full throttle and just let the
engine spin up to 5500 rpm and then I costed up to the next stop sign.
Sounded nice I thought, and then I looked in my rear view mirror and was
horrified to see a white smoke screen that could have been left by James
Bond's car. It was pretty bad. Now, the car doesn't burn oil, the level on
the dipstick has literally not changed from when I put new oil in this
January. I turned it off and started it back up, a puff of white smoke came
out of the exhaust but that was it. Drove it around the block and didn't see
any more white smoke, but I was too afraid to rev it up again. Side note,
the engine seems to run great although it does have a slight coolant leak,
when I come out in the morning there will be a small puddle the size of a
quarter.  I thought I was set for summer. What am I into?

I had a similar problem with my 85/1 944. After about 20 mins of city
driving, white smoke was blowing everywhere. Everyone on the road was
trying to stay away from me, it was so bad. When I attempted to add
coolant and water, it all leaked out on the ground as fast as I was
adding it. It turned out my radiator cracked, and I had to have it
replaced.

I suspect you have a blown radiator or a blown head gasket. Is there
water coming out from the tailpipe too? Also, check the oil-filler cap
and see if it has a milkshake like appearance. If it does, then that's
a sign of a blown head gasket.

Well thanks for the help guys, and it turns out to be the head gasket.  I
just pulled the oil cap off and it was milkshake city.  Today the car
started with no smoke, and at 4500 gave no smoke out the back, so I had my
hopes up for a bit.  Oh well that's life.  How many hours labor will it take
a shop to replace it?

it takes me about 4 hours, at home to change a head gasket, and that
includes washing up afterwards.

My '87 944 Turbo just experienced the same thing. I was going down the
highway and I stepped on the gas to pass a semi and I heard a muffled "pop"
and a huge plume of white smoke started pouring out from behind my car. I
looked at my gauges right when it happened and everything looked normal. I
made it home (about 5 miles) and parked the car. I popped the hood and
noticed the engine bay was soaked with coolant. Thinking it was just a
hose, I started removing them one by one inspecting them as I went. I
didn't find a single crack or split so I don't know where all of the
coolant came from. I decided to drain the oil and check for coolant mixed
with the oil and sure enough all that came out was a light-brown milkshake.
I just spent over $8000 to have a new engine put in and it would really
suck if the head gasket blew already! I heard you should replace the rod
bearings if this happens as well. If I were to replace the head gasket
myself, what are the steps for replacing it? Aside from a new gasket what
other parts will I need? Do I need new head bolts as well?

It's been so long since I've been behind the wheel of a Porsche that I'm at
the point where I'd change the gasket in exchange for some Porsche time. Is
it possible to get withdrawal? Years ago I owned a 924 and then a 944 and
then when I got married they were both sold, last summer I was able to take
out by Uncles 1990 911 SC, and this didn't seem to help with the withdrawal.
Any chance your 944 is in Southern Ontario?
