log frog, in the U.K. HEUI motors are known to be dogs, causing plenty of agro for the owners, the oil change times are often way off mark with motors getting a fresh drink of oil after going well past a 1'000 hrs of hard flog, the oil sample thing is usualy only done on new Iron with an amount of factory Warranty, so these engines have a crap name for being a money pit, I stay well clear of them due to the stomach churning bills that soon collect around them, plus the fear of getting dragged into a bad situation having to live with 1 of the knackers that struggle to run for only a few 100 hours before the next calve down happens, best bet is to box up that 324 into a sale ready bit of steel, with a view to swapping it in for anything that will do a days work, a Doosan will run circles around it without the fancy bills, all that talk about oil changing and oil samples is bull crap, the engines are rubbish with stupid costly parts, this is just my thoughts, but its is a fair discription on a Lemon set-up.
p.s. just noticed you called the engine a Lemon, I wish I had met you before you bought the Dog, I would have told you what you now know, their crap!
