i freaked out when i saw the title, then i saw it was you
look underneath, if there is no mark visible from the hitting you had, dont mention it to the dealer.
its their first thing that they will say to you. its an excuse not to replace it under warranty.
the second thing they ll try, is to change the gasket. Pray to God that you just need a gasket. The replacement procedure is specific, its doesnt need a university degree, but the mechanic must know what to do (mine didnt
). He must clear all the surfaces VERY well, put a new gasket and tighten the bolts WITH A SPECIFIC ORDER, starting from the middle ones and each time tight the "opposite", in other words a symmetric tightening. For details ask the master (Hoygaard).
the third thing they ll try, is to change the gasket once more. Dont laugh, in my case they wanted to replace it again, to test a new procedure, which included tons of glue...
the fourth thing they ll to is answer the phone. it will be Malta's AR general director, asking what the **** is going on with Pat's 147 (like in my case)
the fifth thing they ll do is to let you know that you will have a new manifold on warranty. (that was the last news i gave you about my case)
the sixth thing (that just happened this afternoon) is to inform you that you dont really need a new manifold, because your old one just needs to be put back with a proper way
i hope you solve your problem soon Patrick, all i know is that tomorrow i ll be talking to AR directors once more..
one more thing: dont let the time pass, i read somewhere that a cracked manifold can give you burned valves frown
