Another case or headgasket

Hi,

this morning my truck starting smoking a lot (like to the point I would not see the car behind me) - white smoke, sweet smell.

there is no doubt I have a coolant leak into the engine - and I have been reading part of the afternoon on cavitation.

I would believe it's a blown head gasket as it appeared all at once, but it would make me feel better to hear others saying it.

To be noted, the truck has been apparently running for a while without coolant at all (or almost), I bought it recently.
Sunday morning, it almost overheated in 30 degree weather.
Monday morning I top off the coolant
Wednesday morning "white explosion"

I managed to drive the truck back home, but the engine is shaking a lot.
Also, if you open the radiator cap with the engine cool you can see bubbles.

So, head gasket it is?

I would do a compression test on all the cylinders. I believe you could figure out if its cavitation or a head gasket that way.......

my vote is that it is head gasket. It is rarer than you think to see an engine with cavitation. I know they are scrapped when cavitated but my old one was a dead ringer for cavitation from the desctiption but it was the head gasket. By the way, the risoline will patch almost any hole/piece missing from a head gasket. Dont bother with the ceramic coat and other one in the white bottle. Dont remember the name but they are in a white round bottle. I tried them on that old engine and nothing. I used the risoline and if the head had not been worn through in a slot like formation so wide the tech said it would have been fine. It patched two large holes and some other water jacket stress issues. It worked so well the ford guy went out to get a bottle for his wifes ford ranger. The next day he drove it into work to show it off. The other tech couldnt believe it. If you have a big ol diesel it is hit and miss, reg gasser, i would almost guarantee a fix. No i am not affiliated, just amazed!!!

Welcome to the club, I bought a truck with a 7.3 and 50 miles later the right HG blew.

I am having to wait for the ground to dry to pull the motor and rebuild it.

Are you planning on doing the HGs your self if thats the problem?

92 7.3 non turbo.


@ bill11012: well, after reading about how heavy the heads are, I am wondering. I don't really need the truck and I got it cheap enough so that I could re-sell it to someone with the time to fix it w/o loosing too much

there are people on here that are unable to change the transfer case without a jack too, if you are remotely strong, you should be okay. I removed and mounted my xfer case by hand, just depends on you.

It is actually easier to pull the engine to do the heads.

If you don't have the equipment, it's not! I have an engine hoist but still opted for a forklift to pull the engine. Many don't even have the hoist to handle an engine of this weight class, but may be able to handle the 130lb heads.

True but it is quicker and easier to pull the engine. most towns have a rental store that rents a cherrypicker not this town but most lol. renting is an option he might look at as many new headgaskets have been messed up trying to handle the head in the confines of the engine compartment. Also if it is a pinhole in a cylinder the best way to tell is pull the pan and pressureize the cooling system so you can see where the water is coming from. It is a pain to get the pan off in the pickup.
