Some great work in there, not sure about the job he did on that ACIS manifold but lol.
Could anyone work out why there was an oil pipe from the right hand front of the block to the sump? All I can think of is he has removed the stock oil pressure switch and used it as a return to the sump, but I dont know why you would do that rather than just blank it off? Maybe its to improve the 5E oil pressure problem, it also mentioned RB26 on the writing beside the oil pressure relief valve photo, a few mysteries in there.
