I would say you need to replace the head gasket. I4? V6? Year?

 

1994 v6. First year for the 1mzfe. But what's funny is the bubbles disappeared after the blue devil. Then the radiator blew, and when I put a new one on and filled it with water there was no bubbles. Now that there is antifreeze in him he bubbles. It's odd, and I don't know why water is having a different end result than antifreeze. If it helps, on cold mornings when its cold white smoke comes from the tailpipe. But only when he's cold and when the air is cold. There are SO many problems with him lol

 

+1 on the headgasket. have a pressure and run down test on the cylinders done to confirm.

Haha if I replace the head gasket I might as well put new heads on him. Probably warped as many times as he overheated. He never did shut off though. Oh weell, I want to do a vvti conversion. But hats another topic.

 

And what would explain the lack of bubbles with water? There's no more oil in his coolant since the blue devil, and he's never had water in his oil. Not saying it isn't the head gasket, I think it is, as well as my dad, but why no bubbles with water?

 

Just test for a bad head gasket. If its not the problem, let us know.

 

Quick question. What's the easiest way to check for a head gasket leak with only basic hand tools? My dad told me to put my favorite and nicest shirt over the tailpipe and see if it smells like antifreeze. (But I can't see how it would considering how he hasn't lost any coolant) (but he could just be consuming it too slow for me to notice?) None of the common signs are there except for bubbles in the radiator. And he smokes white smoke, but not much and only when he hasn't been ran in a while and its cold outside. I could
compression test him, but I don't have a tester.to be honest if I remember correctly I don't even have a socket set long enough to reach through the valve cover and extract a spark plug. :\ no mayonnaise oil, no oil deposits in my water. With money being sort of tight, i need a sort of.. (What my dad calls) "shade tree mechanic" method that isn't just checking your fluids. :\ any help would be appreciated haha.

 

You guys I really think its a head gasket/cracked/warped head. I really do. (Probably not cracked). However, the coolant being able to pull off not mixing with the oil is a mystery, and how he's stayed running, this well, and for this long is far beyond my comprehension.

 

Just cause it isn't mixing with oil doesn't mean the head gasket isn't blown. It completely depends where the head gasket failed. I've seen them fail between a water jacket and oil galley so coolant and oil mix but nothing ever gets into the combustion chamber. In your case it's failed between a water jacket and the combustion chamber.

 

Update: strangely... No more bubbles. Nor has the coolant level changed in over a week. Maybe the bubbles was him burping. I'm not sure. But not a single bubble, all the way until he spits at the rev limiter. its weird, but I'll take it.
