Okay Guys so I have been away from this forum for a while because my N42 engine's headgasket blew I decided to DIY it.
Not only did it blow but the block actually had a piece missing and the cylinder head had to go for re-surfacing Cost R780 done a bayview engineering ,Chatsworth ,umhlatuzana the did a great job on it , as for the piece of block missing I had to get it aluminium welded cost R600 and I had to deck it ,Clean off all old gasket , Okay so then I go to “Martin’s Car parts” Durban north great guy gave me all the gaskets etc I needed for this job at a great price R2700, all Victor Reinz so I finally get the head on down to last headbolt and “snap” it broke :argh: , after crying for a while I pulled the head off again , attempted a screw extractor trick with no luck , had to get a thread specialist , John from John’s threads he did a great job broken bolt out , thread repaired with helicoil , I put the head one built her up and she run beautifully now better than ever. Guys remember my initial problem was a rattle when getting to 1000rpm this was caused by the misfire due to the headgasket broken between cylinder 1 & 2 and on the way to break a no4. Also discovered a broken bottem guide had to get a new one around R650 after 15% disc from BMW.
