it's hard to maintain the old engine, of coz u need small $$$ but always...
why not invest more $$$ but 1 times only... believe me! i already experienced it... ;)
i accidently broken a bolt during tighten my oil line from turbo to oil sump. the broken nut sunk inside and the bolt size is 10mm. Do anyone experience this and how to remove the stud/nut.:
