Question about Cars & Trucks
When I try to fill the radiator with antifreeze, the antifreeze level always stays low and somehow it leaks into my oil pan and mixs with the oil. The way I discovered this problem is, I was driving and had a large white cloud of smoke coming from the exhaust pipe and found antifreeze leaking from exhaust pipe and boiling into a white smoke. I pulled the intake thinking that it was the intake gaskets, but the LT-1 does not have antifreeze ports like a typical 350 sbc, so obvious it is not leaking from the intake gaskets. Where could this leak be occuring? Any help would greatly be appreciated tremendously! Thanks in advance!
Most likely a head gasket. The coolant is forced into the oil chambers and mixes. This too leaks into the exhaust gases and burns off as you describe. You usually get oil in the coolant reservoir. This can be checked with a test strip available at automotive supply store. It measures the acidity in the coolant.

A quick check you can do to help your troubleshooting is to remove the radiator cap then start the vehicle. (Ensure radiator filled so you can see fluid level). Watch the fluid inside the radiator. Initially after you start the vehicle you will get some small air bubbles but they should go away in less then a minute. If after a couple minutes you have bubbles continually coming up or it starts bubbling out of radiator then you can bet on the Head gasket. If you do not get the bubbles it dosen't rule out either one but if they are there as described then you can look at the head gasket.

Sorry to be the one to tell you but you have a major expense on your hands. It is either a blown head gasket (the cheapest solution) or a cracked head (the next most expensive solution) or a cracked block (don't ask! ). Take it to a shop and have them do a compression test to find out which cylinder is leaking. Then get at least three quotes on repairing the damage. Good luck!!

Testimonial: "thanks for advice. head gasket went a few months ago.they charged me £650 to repair it"
Yes there is another way, someone can be messing with your head and pouring water in your oil cap. Do have water in your oil or oil in your water or both? A product called sea foam does a miraculous job at getting water out of oil. As far as keeping it from happening further, the cheap way of course is "bar's stop leak" but man can this stuff do a number on clogging your heater core, even if they say it doesn't, it can happen.

SOURCE: WHAT ANTIFREEZE GOES IN 1999
Ethylene glycol green type mixed as 50/50 ratio.Many brands would be safe to use in your vehicle such Prestone,Texaco but as the article below states Ford perfers you purchase their brand of antifreeze and that you should not use propylene glycol. Please click the link for more information.
Here is a Ford technical service bulletin on this at this link.It is PDF file.
