hi, every one i have an windstar 98 and three weeks ago i put a new heads all the gaskets are new and now on every trip even if it is small i have to put coolant and somtime she also she is smokes by the exhaust but is no all the times.the oil motor is clean,in the cover cap i see milky subtances and also and in the pcv too. she is running nice ans rpm is 800 and besides all this all else is all good.if anyone have any idea please let me know thank[sm=dontgetit.gif]

 

What was the original reason for pulling the heads? Head gasket failure I'd assume..

So,,,,

'Both' heads were replaced, new head gaskets, AND new headbolts? Were the heads reman. replacements, used, or the originals as rebuilds? Are you certain the head gasket/s weren't damaged during the build/install.. Had it ever seriously overheated?

 

hayapower but the oil is perfec overheated no way

 

i move the upper intake and no see nothing bad no milky oil

 

Are the heads new?
Just the gaskets?
Sounds like a crack in the cylinder head.

 

I fix the last problem just with a radiartor flush https://www.fordforum.com/micons/m16.gif

It sounds like a crack in the head, or the head gasket got damaged during the install process.

 

Could also be coolant leaking through the the lower timing cover bolt. The 3.8 has atiming cover bolt that extends into the water jacket that the thread seal can deteriorate and cause coolant to leak on to the crank thrust bearing. To check start the engine cold run 10-15 seconds (yes second) to pressureize coolant system, shut down and check the edge of the catalatic converter for coolant. You will also tend to smell the sweet smell of cooked coolant but never find a wet spot and the water pump will not be the source. I had a 95 W-star bought used, found leak, took to dealer for leak, leak was in timing cover and had to replace timing chain. 5 weeks later started getting bottom end noise, end up having to have new motor.
