on my 04 1.2 clio i have a blown gasket between the exhaust manifold and downpipe. the gasket i took out was the ring type about 3 inch diameter. when looking for spare parts i only found the diamond shaped one relating to my car. upon further investigation the gasket i took out was for the d7f engine but mines a d4f. the exhaust system is the same for each engine it just seems to be the gasket which is different. has anybody else come across this and does it matter which gasket i put back in?
