Lately I have noticed a noise that sounds like a rattle or vibration (tin/metallic sounding) coming from the engine area at 2800/3200rpm.
Any ideas on what could be up?
The truck has done 76,000km and is a 1993 MU 2.8L Manual, but I think I don't think it has had the best life (Jap import, parts delivery truck)
In august I have a big service planned, change glow plugs, timing belt, most fluids, tune up, filters etc.
Any other things I should consider? What about the injectors?

I had a similar noise at 2200 It was a loose bolt on the sheild over the intercooler.
Take the fan belts off and see if the noise is still there but dont run the car too long without the belts. What side of the engine is the noise coming from.
Why change the glow plugs. the cold start system on that engine only works below 3C How often does Auckland see those temps. On mine I dont wait for the glow plugs even when theres frost on the bonnet although it smokes a little more when that cold and frequently takes 2 or 3 goes to stay running

Check the 4 studs holding the turbo in place, especially the two bottom ones which you can check through the front drivers wheel well with a torch. J

Thanks for the ideas
When I start the MU up in the morning, it gives off white/grey ish smoke untill it gets up to temperature.
The mobile mechanic who overhauled my rear brake calipers & replaced the clutch slave (it broke loose and I had to get home with no clutch, luckily only 2km's) told me that one of the first things to do to try and combat this is replace the glow plugs. And I believe it doesn't usually cost over $50.
True or false?

greyish smoke for thr first 2 to 3 minuites when cold (under 12) is quite normal. Only worry if there is a lot or it doesnt clear that quick. The glow plugs only glow 0.5 sec unless its under 3 C then they glow for 30 sec. This is measured in the thermostat housing. You can remove the sensor wire by unpluging the right hand wire on the thermostat housing to see if it makes a difference but it also advances the timing so dont drive too far like this.(it will be obvious) Cant comment on price

OK, have been in the garage for a while. I don't have an intercooler, so a bolt on that can't be loose. The belts do make a annoying noise especially if any water gets on them, but goes away when they are warm & dry. I am not a mechanic, so do not want to take anything off without someone here guiding me (like the fan belts). Had a look at the turbo and found out it's still bloody hot after an hour of being off. The bolts on top feel firmly in place, couldn't see the bottom bolts. Had a look inside the driver's wheel well, could only see a protective wall, no turbo. Went under car, no good view of turbo.  The service I want to do will be an overhaulling one. As it will be one year since I bought it and it was a fresh Jap import. As well as most fluids, filters etc what else should I ask them to do? Any belts? Anything I should or can do with the injectors? The MU manual says that there is a “Fuel Hose in Engine Compartment” and that it should be changed every 4 years. What is that, and should I do it? |

dont worry about the fuel hose This is now checked every 6 months as a Wof. If the belts squeal when wet change them Also timing belt should be done at 6 years or 100000k so do it. All the good books say replace all the water pipes at 6 years as well although they dont break till 10 - 16 yearsThey can kill your engine.
All the fluids and filters good idea. Oil should be changed every 6 months or 5000km.
If your giving all this to a garage to do please be seated when asking for a quote

Ok, so I'll go to a garage and ask for their best Deisel service plus replacement of all belts, including timing belt, water pipes and change all fluids and filters.
I saw somewhere that just changing the timing belt can cost $700Au... is this true?
And if I get an AA service and repair shop to do this, how much do you think would be reasonable? ($NZ)
I think I should start saving now.

Theres about 3 hours work in a timing belt and the belt is about 40 trade at bnt. Its not that bad esspecialy as some of this work is also needed for some of the other jobs. Your water pipes may be ok A mechanic would be able to advise The fan belts might cost 100 all up but you have them off when doing the cam belt so might as well change them. Your already draining the cooling system for the timing belt so new coolant is part of the cost.
I dont know your mech knowledge A lot of this can be done with very basic knowledge and tools although cam belts do req a little knowledge. I would do all this myself.

My experience tells me that if I try myself, I'll break something. I'd get the work done with the AA service too, so i'd get the full report and everything, which I want. Remember i'm only a 15yr old with no mechanical car experience.  |

Adding to all the good things Geeves has already said, re your glow plugs and mobile mechanic I note he says replace the glow plugs. This is a bad habit we should all be aware of.
He's a part swapper rather than a repairer. Thats a subtle differance in appearance but a significant differance in the wallet. Especially in the tricky hard to find faults. This is a skill and a craft that not all have.
The glow plugs should be tested and diagnosed as faulty rather than just guesses to replace. It can be hard to find good fault finders and repaiers in our day and age of a throw away society.
Bear this in mind in you will be in a better postion to make informed decisions of what really is good customer service.
