Outer Limits 4x4 Board

Hi,
Looking at buying [only talked on phone] 91 mav xl, diesel, non turbo with 205 000km, no real 4wd, some towing 17ft caravan on holidays and driving to work. Price $9800

Last two owners owned for about 10 yrs and serviced at the one place, at about 8-10 000kms. No major work done to injectors or pump.

Question is, should I be put off by not being serviced every 5000kms and what problems are caused by not changing oil at 5000kms. Also, any good vehicle [diesel] inspection mechanics in the Wynnum Manly area [Brisbane]

Thanks in advance

Craig

no

Hmm I personally wouldn't be put off, mines got 510,000k's on it and has genrally been serviced every 5,000-10,000k's. I personally have noticed that the oil does degrade a lot once it gets over 10,00k's though and particularly if you're doing a lot of towing and hard work. But really mine has been flogged towin horse floats and boats its whole life and it hasn' had a drama. Sorry I don't have any technical info for you. Good luck with it.

If you realy want to look after your diesel it should be surviced every 5,000. Especialy if ya toweing and realy labouring that motor.

depends on motor a bit.

older ones are 5000km oil change. newer ones are ment to be 10000km oil change. however type of use and type of oil and fuel used can make a big difference.

A 91 Mav should have its oil changed every 5000 kms. If you still are interested but want to limit your chances of having to do a rebuild in the near future, take it to a diesel mechanic and have them give it a good inspection. You will want to be sure that it has a leak down test done. If they are only doing engine oil every 8-10, than it is a good possibility that they did not do all the other lubes on time or at all. A quick thing you can check for is blow-by. Just take a look at the air fliter to see if it is oil foiled (provided it is a paper filter). If you see blow-by oil on the filter than walk away and don't bother paying a mechanic to inspect it.

You can expect to replace the injectors. Hiflo has a good price on new injectors (not reconditioned). The IP may be good for a long time. It may just need seals but you might as well budget in a pump rebuild. I had mine rebuilt here in Canada for $2,000. You can get a rebuilt pump from Hiflo for around $1200.

Good luck.
