Coolant leaking from back of motor

Started laeaking bad 2 days ago. No power loss no water in the oil no white smoke from exaust. I am pretty sure it is leaking right around the # 5 Cylander. Is ther a water jacket core plug there or what could it be. I originaly thought blown head gasket but now I am thinking freeze out plug.

Hi there
to answer your question it could very well be a frost plug that came out
but to verify this pressure test the system
but first take brake clean and clean the area well
so you can see it better
there is also a dye you can get to see it better
but i have used food coloring because the collant is one color it would help to have a different color to verify

White smoke delica


The thick white smoke is either burnt oil or steam you can easily identify the smell of burnt oil not really sure why you thought it would be a good idea to put a 2 stroke mixed fuel in but more than likely that alone fouled your spark plugs. But if the problem preceded the fuel blunder then your either have a bad intake/head gasket, leaking valve seats, or bad main engine seal. Replace the spark plugs and check cylinder compression. Change your engine oil and check to see if it contains water/coolant also watch for coolant or oil consumption

Excessive exhaust smoke on the first start of the day


Sounds like the valve guides are leaking oil into the cylinders, or there is a coolant leak somewhere. Usually white smoke is coolant but could be oil.
Are you adding either fluid often ?

Why would oil be in my coolant?


Oil in coolant, white smoke at start up = blown head gasket or cracked cylinder.

White smoke is water vapor from coolant. Only at startup indicates a small (extremely small) leak -- it will get bigger. Only at startup is because as engine cools it sucks water into cylinder. A compression check will tell you which cylinder is the problem (could be multiple)

White smoke out exaust pipe and stalling


Any time there is white smoke coming out of your car's exhaust system, it is an indication of a leak. but a leak that is allowing either oil, coolant, or transmission fluid to get into the cylinders. The smoke is from the leaking substance not getting completely burned off like the air and fuel mixture does under normal operating conditions. pull the oil dipstick and see if you have traces of coolant in oil. if so you have either a bad manifold gasket or a head gasket went bad. good-day !

Overheating still has coolant, white part blew out of the tailpipe, made a banging noise then starting smoking. Overheating with all fluid high. Told there was a front seal oil leak but not bad. Lost 2...


  • White smoke out out the tail pipe means you might have just blown your head gasket. White smoke is water (antifreeze) burning with the oil.

Was the smoke white? if so it is probably your head gasket you can still save it if you want as long as the head isnt cracked as well then it probably just isn't worth fixing and from the sounds of it sorry to say but I cant be sure with out seeing it

White cloud of smoke through tailpipe


well I'd say that coolant is definitely leaking into the combustion chamber, albeit at a slow rate (for now). It could be anything from a blown head gasket to a cracked block or head. I'd get it to a shop as soon as possible and not drive it any more than need be until that point.

Saab 9-5 blowing white smoke from exhaust


One way to check for a blown head gasket, is to simply smell the coolant reservoir. Pop the cap, and see if it smells like raw gas. Every headgasket, I've diagnosed has had this smell, even if the oil is not contaminated. Another way is to hook up a coolant pressure tester, and run the vehicle for 15-20 mins or so. If the head gasket is blown, the pressure will exceed 15 psi. sometimes as high as 25 psi. If there is oil in the coolant overflow tank, the head is cracked, about 90% of the time.
I'm working on a 03 Saab 95 2.3l t. This vehicle smokes on initial start up, then the smoke disapates, and the vehicle is fine. Another mechanic diagnosed it as bad valve seals. I disconnected the pcv system, and the vehicle no longer smokes. If the valve seals have gone bad, the vehicle will smoke on acceleration. Also if the turbo seals are leaking it will smoke more heavily on acceleration.
