I HAVE JUST PURCHASED A MRK 3 1.8 GOLF. VEHICLE PURCHASED WITH COOLANT LEAK WHICH I WAS AWARE OF. ON FURTHER INVESTIGATION HAVE FOUND CORE PLUG ON BLOCK MISSING AND ALSO ONE ON THE MANIFOLD IS MISSING. DOES ANYONE KNOW IF THESE ARE A KNOWN ISSUE WITH EITHER CORRODING THEN BEING BLOW OUT OR IF UNDER CERTAIN PROBLEMS THEY BLOW OUT. JUST DON`T WANT TO WASTE MY TIME REPLACING THEM TO FIND THERE IS A KNOWN ISSUE SOMEWHERE ELSE CAUSING THIS FAULT. MANY THANKS STEPHEN.

 

i dont think its a big issue. not 100% sure tho. I might be wrong.
