To keep the turbo motor running well you MUST have clean air, fuel and oil, so fit an air snorkle with a quality air filter, K&N, Franz, Unifilter, fir a secondary fuel filter before the factory spin on one, like a CAV, Franz etc, now for the oil, fit a oil bypass filter or one of the new centrifigual replacement oil filters (Opposite Lock), Have someone like Berrima Diesel tune the motor www.hinet.net.au/~diesel/welcome.html The life of a turbo V non turbo depends on how well you look after it, they should give you the same klm's with very little trouble, my HJ60 did 275000klm, and the only mechanical prob was a water pump, I had a rear main seal go and I replaced the clutch during this time, I dod the injectors at 160000klm, (60000klm over due) they were fine just needed a clean (cause I ran the extra air,fuel,oil filters) the Cruiser was over 15 years old whrn I sold it and still going strong -- Ron Humphries www.geocities.com/aussietj My 4WD Club www.geocities.com/nd4wdclub FROM: "Mike Locke" SUBJECT: Re: Oil filter question/Isuzu diesel DATE: Mon, 14 Feb 2000 08:48:50 -0800 ORGANIZATION: http://extra.newsguy.com NEWSGROUPS: rec.autos.4x4 Kong wrote in message news:38a76b29.8148860@news.jaring.my... > I was at the dealer and came across 2 different genuine Isuzu OEM oil > filter listed for my 3.1 turbo diesel intercooler. > 1st filter is shorter but slightly bigger diameter and cost less. 2nd > filter has smaller diameter but much longer by ~3 or 4cm and has the > word "Combined:full flow/By-pass" printed on it and cost almost double > in price.

One is a low pressure drop but only moderately effective "full flow" filter that filters the main flow of oil that goes into your engine. The second is a high pressure drop "bypass" filter that filters only a small amount of oil very effectively, but presumably just returns this small amount of oil to the crankcase. The later filter is intended to remove the superfine grit from your oil that causes most of the wear in your engine, and theoretically will increase your engine life expectancy. -- S'later, Mike Locke karenml@rahul.net or lockem@scrserv.com FROM: ralphpwood.com SUBJECT: Re: Oil analysis DATE: Mon, 31 Jul 2000 23:36:05 GMT ORGANIZATION: Deja.com - Before you buy.

But he does do an analysis every 4 K miles without fail! The US Air Force, Shell Oil and Detroit are studying a 1990 Peterbilt with a 425 HP Series 60 engine. It uses the standard full flow filters plus a Gulf Coast 0-2 oil filter and a F-1 fuel filter water seperator. Every 10,000 miles the big Gulf Coast filter is changed and 3 gallons of new Shell Rotella T 15-40 is poured in. Every 50,000 miles the full flow filters are also changed and more Rotella is added. The oil is analyzed every 10,000 miles. It was torn down and inspected for wear at over 1,000,000 miles. There was no wear found except the rings which were replaced. The hone marks were still in the liners. Detroit people said the ring problem was caused by a split in the hose to the intercooler. The truck has had 2 oil drains. One when the breakin oil was drained and at 250,000 when a leaky pan gasket was replaced under warranty. The big filter uses Bounty big roll towels. EnviroSense Department of Defense Pollution Prevention Technical Library Bypass Filter for Vehicle Motor Oil Introduction: Gasoline and diesel fueled internal combustion engines require libricating oil to reduce friction and dissipate heat. The lubricating oil must be changed once the oil's effectiveness diminishes. Lubricating effectiveness generally does not deteriorate in high-quality oils, but what does occur is contamination of the oil with particles and a breakdown of the lubricating oil's additive package. The additive package, which can be 50 percent of the oil's volume is responsible for maintaining pH and preventing detrioration of the oil. Bypass filters are designed to remove smaller particulate than would normally be removed by the engine's normal filter so that oil changes are not necessary. Oil added during filter changing, and to replace burned oil, is normally sufficient to replenish the oil's additive package. Ralph FROM: ralphpwood.com SUBJECT: Military bypass oil filters DATE: Wed, 13 Dec 2000 16:26:37 GMT ORGANIZATION: Deja.com NEWSGROUPS: rec.autos.4x4 It may have changed but a few months ago I found that four submicronic bypass filters had been approved by the Pentagon for eliminating routine oil drains and most engine wear on military equipment. Two used toilet paper. One used cotton and one used a mixture of cotton and cellulose similar to toilet paper. There are several submicronic filters around the world that use either toilet paper or elements that are similar. I was in a auto parts store the other day looking at filters. One element for a fuel filter was almost $30.00 and was too thin for fuel. Another element for a heavy duty diesel engine lube oil that was huge and 100 times better sold for less than $10.00. It confuses me sometimes. Both filters were made by the same company. You have to be street wise and do your research.

Thomas Bentzen" Reply-To: dtlc@helios.net Subject: Re: [DTLC] Oil Change To: dtlc@helios.net Here is more advice. Use either Mobile Delvac 1, or Amsoil Heavy Duty Diesel oil. These are the two highest rated diesel specific oils out there. Second, if you really CARE about this engine install an after market BYPASS oil filter in line. Standard oil filters filter to around 20-40 microns. Bypass oil filters filter to less than 1 micron typically. I have a 2001 TDI Jetta, a 1987 HJ60, and a toyota diesel powered long wheelbase samurai. I run both the Amsoil and Mobile Delvac1 in my rigs. Ive sent oil to the lab to have analysis done to see where I was at with respect to necessary oil changes. With proper filtration (either a bypass filter or changing your main engine oil filter every 3000 miles) you can safely go 20,000 miles between oil changes! Now this isnt just me taking here, this is information from oil analysis labratories. There are a number of bypass oild filter too: http://www.amsoil.com/products/bf.html http://www.bestsyntheticoil.com/amsoil/by-pass.shtml http://www.gulfcoastfilters.com/ http://www.oilguard.com/ TB http://buschtaxi.org/cgi-bin/ikonboard/topic.cgi?forum=9&topic=5
