Hi Guys, I’m a newb from Tamworth, NSW & my daughter has just got an old d21 Ute. It’s a 2.0L petrol & it has 8 spark plugs, but only a 4 plug distributor. It had a pretty bad oil leak from the rocker box, most of the screws holding the cover were really loose, so I hope I fixed that. The 4 plugs on the inlet side are connected, the others are not. As the rocker cover screws were loose & it’s missing a bolt in the exhaust manifold, I’m assuming that someone’s done a head swap in the backyard. Does that sound right?
