Hi Everyone :).. I have an Audi A4 2004 and its been diagnosed with a head gasket leak.. Now unfortunately, the car won't start. Any ideas why that would be?
I had just bought this "head gasket sealant" and was planning to try that first before
completely repairing the problem.
If the engine won't crank most likely one or more of the cylinders has coolant in it. This hydrostaticly locks the engine since the coolant can't be compressed. You'll need to remove the spark plugs then crank the engine to get the coolant out of there. The only stuff I've seen work for head gaskets is a product called Blue Devil. BUT you must follow the instructions on the bottle EXACTLY! Other products will clog up the cooling system and create other issues such as no heat, overheating, etc. HTH. - Jim
do your self a favor don't even bother with that head gasket sealant. the audi's engine runs to hot for it to be any real use. What you need to do is have the head torn down and replace it with an either original or after market gasket. tho i recommend getting it from audi. When it comes to the cooling system in an audi it is very important you fix it properly or you risk not having an engine at all. thats the risk with high performance engines. if this were a gmc or ford i would say go ahead do what he said and seal it but its an audi and doing a half arsed fix only causes more issues and more money spent
Yes Mr pro fixer take the car to audi have them fix it thats great wow pal. Forget that you know it all. Blue devil works for all cars I ve used it on my audi and bmw and full size truck and its been just perfectly fine just follow directions and that is your protection!
I am not saying to take the car to audi and let them fix it I am saying use genuine audi parts to repair the problem When your dealing with a blown head gasket it usually means you have a 50/50 chance at a warped head. Slapping on some sealant won't fix the internal issues as your cylinders will not have the right pressure. bad pressure no running and no amount of sealant will fix it. the head has to come off and be inspected then a new gasket used. So Mr i want to find something to harp on why not look into the full explanation before making your self look like an idiot... sound about right ?
