    Hi Arthur,

    I have a new relief valve spring and plunger if you need it, BUT I would suggest dropping the sump and removing the relief valve plunger etc and see if it is sticking/ scored. Take you about an hour from start to finish.

    Oil and Filter....

    For sake of ease...Spin on a new Ryco Filter

    If no joy.... Start looking elsewhere!!!!

    I agree with you Tombie, I know tah Donaldson filters were good, I used them on tractors but it is more than a coincidence that the perure plunger it is going to play up just when I changed the filter.
    The engine has a little use, 100000 km in 14 years, so the possibility of residues on the bottom of the sump is there

    Now if you didnt have an oil pressure guage you would be driving around with no worries at all

    If it had been a navara with the 3 litre diesel,it would have blown the seal on the oil filter & pumped all its oil out,as my son found out the hard way.I presume the Patrol would do the same as engine is similar.Common fault when the oil pressure relief valve does not do its job,for whatever reason,usually at cold startup with these engines

    Arthur. I would try a master guage first. If you have an electric guage / sender. could save a lot of work. Just a thought. Mark

    I know but to me engine temperature and oil presure gauges are a must and an essential instruments to helping you with the preventative maintenance

    Found the problem.....loose terminal in one wire
    Bloody Murphy's law! why the terminal have to come loose just after the oil/filter change just to confuse things on the trouble shooting. I was thinking thet the problem was the filter.
    Oh well was a cheap repeir and no damage on the engine
