hi all i have a 2001 wizard deisel with the 4jx1 engine , the oil light started to stay on for upto 30 seconds at cold start up had it looked at was told that it appeared to be a wiring fault as when they did oil pressure test from oil filter had heaps of pressure problem then went away for approx 9 months untill yesterday when the light stayed on again for extended lenght of time as it went out my turbo started to whine hence 1 blown turbo has any one out there had the same problem A is it a turbo problem or B low oil pressure at top of motor all help greaty appriecated

the turbos arnt the best is replaced with a chinese one, need to do a oil pressure test at the oil pressure sensor and see what it is when its playing up, the oil pickup o rings have faults, it could also be a wiring fault though

the turbo was replaced with a genuine unit had o rings replaced with turbo then had them replaced 9 months ago when oil light problem arose also had oil pressure test done at same time had instint pressure , light stayed on other day then as i moved off light went out turbo whined and ideas cheers

low oil
oil contaminated with diesel
damaged oil pump/s
Strainer as per robs post
After market oil filter with no anti drain back.
Should always wait for oil light to go out before revving engine
What mileage?

if it was mine i would just run a machanical oil pressure gauge in it to make sure as it has been a problem for a while, sounds more electrical than machanical if you have had it checked out and its still going would have run a bearing in the engine by now with no oil pressure
