Hey, so I am fairly certain I have a blown head gasket. I haven't done a compression test. I loose a little coolant and under the oil cap is really milky and all the way up the dipstick too, I dont have a temp gauge.

I was wondering if anyone has tried "Rislone head gasket fix" its just a bottle that you add to the rad and it says it permanently fixes cracked blocks, heads, blown head gaskets and so on. I am just not sure if it is gonna work or not.

Thanks in advance.

 

not worth the issue...usually it fixes the leak but causes other issues...like blockages and overheating...

Just pull it down... pull the plugs and find the cylinder using the water and find where it is coming from. could be just an Intake leaking...thats an indication if none or all are using/burning water... if the center cylinders are then it could be a gasket or crack

 

what do you mean by the water?

 

He means take out each spark plug and check then to see if they will show which cylinder the coolant is going in. Water is the term most people use for coolant when talking about leaks

 

if the cylinder is burning water it will have white crusties on the porcelain and it will be light greenish in color if its antifreeze...

so if you run straight water or antifreeze you know what to look for....

 

...so all the cylinders have a slight green colour to the plugs, and one is covered in oil aswell. couldnt run a compression test cause my tester is crap and wont stay in the hole.

 

I have a 1986 FORD F 150... its leaking very little antifreeze somewhere underneath truck can t seem to find it temp gauge rises up then gose down back in forth any idea,s thx

 

Is it possible that it could just be condensation build up? The water thats burning in the engine might of got in there from when i went wheeling and the breather tube was down by the wheel. I dont usually warm it up much, i drive it pretty quickly after firing it up usually. If it had a blown head gasket, I would assume it would run worse then it does cause it still runs just as good as when i bought it a year ago and there was no foam when i got it just in the past month or two it showed up.

 

No, condensation will not show on the plugs, its burned up within minutes when the engine is running, condensation you see is from the cats burning it off from the exhaust, as far as the milky stuff, is your pcv valve hooked up and working? Also might be an intake gasket as the good Dr said, that would cause antifreeze and oil to enter the combustion chamber, making it seem like a head gasket is bad, also do a compression test cold, a warm engine will expand and possibly seal up the leak.

 

the pcv valve is still good yes. so if i run a compression test and the numbers are good then its the intake gasket and if low then head gasket?
thanks
and one thing i forgot to add to the last post is...mostly all of my driving is in short trips...usually only 5 minute drives
