Anyone else had problems with blowing head gaskets on there turbocharge gas vehicle, i don't seem to get anymore than about 10-20 thousand km's out of one before having to replace it. The car has been recently dyno tuned and according to the car its running spot on, but its full throttle mixtures are at 12 to 1, and in my book on gas thats a bit rich and would be making cylinder temperatures rather high.
I seem to get different information on gas from anyone i speak to, some say that it doesn't hurt an engine to run lean on gas, it apparent decreases cylinder temperature, some say you will destroy a motor if its to lean on gas, but the one thing they all say is if its too rich it will burn a piston out. But how rich is to rich? stoch is 15.5 to 1
Fix the problem as inlower compression,more retard timing or richer/ correct mixture.Otherwise it WILL keep blowing gasgets!!! Thicker gasget may solve the compression but keep in mind you are loosing your quench area and will loose power..If it's blowing gasgets something is out of tune and the rest of the engine will follow..It's obvously detonating at some point...?? If std eec[tune] there maybe too much advance in mid range where boost is realy working for you...
Don't be afraid to try something new. Remember, amateurs built the Ark...Professionals built the Titanic!
