    Question How do you check the oil pressure on the Y20DTH engine?

    I'm sure that is why i've killed 2 turbos.

    I've had a look in the Haynes book... it looks like to get to the oil pump i need to remove the sump. That is ok for me, i've already changed it so i know what to do there.... although i can see a small problem...... sump off = no oil = very very low oil pressure

    So can anyone help? Where do you check the pressure with the sump still on.

    The shaft has a lot of play in it.

    To test the oil pressure you will need a tester guage. Look on the SEALEY site under VS203 or VSE203. Remove the oil pressure warning light switch (located at the rear of the engine block above the right hand driveshaft) and replace with a pressure guage.

    If you take it out be prepaired for some oil loss, best wait until you can source a pressure guage, they aint cheep!

    Well, it's throwing it down So i'll have to wait untill next week to check it out.

    Quick question, Do you know if the oil feed pipe to the turbo should always have oil in it even if it's been stood for a while?

    I think it should - any other turbocharged engine I've dealt with will keep oil in the turbo, because otherwise an abrupt start could have the turbo bearing knackered before oil got to the tub.

    There's some engines have specific turbo bleeding procedures, might be worth talking to someone who specialises in turbos.

    Thats an ineresting point raised by ZS, I would be interested in anything you can dig up on turbo bleeding procedures. A few pointers on taking care of your turbo are-

    1. Changing the oil and filter at regular intervals, around 5000 miles.
    2. Using the correct oil, as a turbo generates a lot of heat through compression. Wrong or old oil can coke up the bearings causing poor lubrication.
    3. The oil pump pressure is adequate for the feeds to the housing. Less likely is the situation of over pressure causing oil to push past the seals and burn
    the bearings, this will depend on how suped up your engine is.
    4. When you stop alow the engine to idle for about 30 seconds as the oil will cool the bearings, I don't mean a trip to the shops, but if you have been
    gunning it.
