Burst broken (with photos)

I greet you, I am full of pride now for the second time bought a 626 coupe last week ( the 2.2) car runs or ran a week great after I made some small things. 250tkm he has now down and this morning a plunger has said goodbye. I took off the valve cover and looked at it. the engine has already clacked (as with almost all coupes it the running power) but after I had tilted the product against valve flaps it was getting better and better. I was not able to hear any more. nevertheless, the thing decided not to like me anymore and gave up the spirit. my questions to you: does someone lie around like this? if not where do I get it FROM MAZDA. surrounding scrap sites I have abteleniert – has no one a motor of that flying around. at nissan kost the thing new just under 100€. at BMW only 10€ with what should I expect CA? and if already openly then vielleicht immediately all the exchanges? write to me times your mineununununun many thanks in advance and on all sides good travel http://img477.imageshack.us/my.php?image=mg2680grenderncw0.jpghttp://img339.imageshack.us/img339/1551/mg2681grendernzp6.jpg
