hrers the low down, lets see if i can tap the infinate wisdom of the idi basement for this one?
the coolant is dropping at a rate of 1.5-2 gal per hour of highway driving
it will sit and run for an hour at varring throttle speeds (mainly idle)and not loose any coolant
if i drive for a short distance and take off the rad. cap and look, there is lots of white bubbles -a little foamy on the top
no excessive press in the coolant system but some
could the rad be restricted letting the wp "suck" in air and blowing coolant past the gasket?? [img]/ubbthreads/images/graemlins/shrug.gif[/img]
im going on a long trip soon and want to get this fixed first!!
thanx in advance, this is giving me a headache [img]/ubbthreads/images/graemlins/tongue.gif[/img]

Man I hate to say it, but it sure sounds like caviation. Some tests to do.
On each cylinder, position the piston at TDC, and presurize the cylinder with compressed air through a glow plug hole adapter. You'll need to hold the crank still somehow for this. Check the rad. If no bubbles, repeat the test with the piston at BDC. If no bubbles, go to the next cylinder and repeat. If you find bubbles at TDC, then it may be a cracked head or bad head gasket. If bubbles at BDC, start pricing a short block. [img]/ubbthreads/images/graemlins/crazy.gif[/img]
any other ideas, there is no indacation of coolant in the cyls whatsoever
could it be the 4 wp bolts?
i think the front timing cover may have incured a few scratches when cleaning it [img]/ubbthreads/images/graemlins/blush.gif[/img]
not to mention i dont have many diagnostic tools or air compressor [img]/ubbthreads/images/graemlins/shrug.gif[/img]

just did a complete gasket set due to head gasket failure...fun w\no garage!!

Was it really head gasket failure, did you see the failure point and did it jump out at you visually, or was this just a guess by some shade tree mechanics.

Can you go through what your symptoms were before and what all you did to it, you can try pulling the water pump and checking it out, did you put sealant on the threads, but i would recommend finding somebody that can do the test Mel stated, did anybody do anything to your heads while they were off?

In my opinion ya got to get it up to temp let it cool a little then remove the G plugs and turn the engine over with the fuel pump wire disconected and see if there is any coolant comeing out the gp holes.
As Mel stated it sounds like a cavitation problem!The oil cooler is a vague possablity!

the only time there is any white smoke is when it is cold outside
the water in crank case evaporates and steam burns trough the cdr , white smoke
i realy doubt its the big "c" as it will sit for two days and not loose any coolant
the only time there is coolant loss is when driving , it sat at idle for 30-40 min. and did not loose a drop, went for a 10 min drive and it lost a half gallon
this is very weird, i know, but thanx for all the help
what next [img]/ubbthreads/images/graemlins/shrug.gif[/img]

Definitely don't drive it anymore. If your oil turns to chocolate milk, you'll be replacing everything.
Do the test Mel suggested. At idle the cylinders might not have enough heat/stress to open up a pinhole, but it might while driving.

Magnafluxed and SURFACED [img]/ubbthreads/images/graemlins/eek.gif[/img] [img]/ubbthreads/images/graemlins/eek.gif[/img] [img]/ubbthreads/images/graemlins/eek.gif[/img]...how much did they remove. What was their overal thickness of the heads after surfacing.
I do have info from AERA (American Engine Rebuilders Association) which states the IH/Nav minimum head thickness after dressing/milling should be no less than 4.7950".
