Yep...

White smoke typically means coolant is getting into the combustion chamber(s)...

Did you have the head checked for cracks by an expert? Some cracks in the alloy casting can be almost invisible and open up as the engine reaches operating temperature.

Good luck,

Could be a crack in the head or in the engineblock itself.
Dismantle and get someone to check the head for cracks with some pentrating fluid and some developer-spray..

Then it's the block itself or the gasket that need to be checked..
You could maybe try to get someone to check the exhaust ? Toi see if if really is vapour that comes out..

I have not seen a...

M110 block for a very long time, but if it is similar to the late M130 block, there were "slots" cut into the block between the cylinders; these slots were between the holes that allowed for coolant to pass from the water jacket in the block up into the head.

These slots [if present] were a problem, as due to the thin cylinder walls, there was very little "meat" for the head gasket to seal against.

The shop that I was affiliated with would fill the slot with an epoxy resin, trim the resin flush, and clean the water passage holes; this would allow the head gasket a little more contact area for a better seal.

Good luck with your problem,

JR

i was wondering. could it be water and coolant in the exhaust. i have only turned on the car once since changing the head, and it ran for about 15 minutes. should i let it run longer before taking the motor apart. someone told me it should run at least an hour. any help would be appreciated. thanks

Could be...

If you are going to run the car enough to make sure exhaust is free from old coolant and condensation, I would recommend that you monitor the engine during the entire time you are doing this, i.e., do not start her up and just walk away...

After a partial rebuild, the engine should run for 2hours+ preferably while driving.. So it's not the same rpm all the time..
