Power issue with 56 plate L200

[Matthew Arnold]

We have noticed since monday that our truck is underpowered. We lent it to a colleague on Monday so he could go to meetings and such. When he dropped it off with us he was crashing about a bit as he came down through the heath. On speaking to our family mechanic he thinks it may be the turbo on its way out. It is very intermitent. We took it for a good run on the way home this evening just to clear out the pipes of any built up crud and we noticed that it was kicking in at around 4k rpm when it would normally kick in around 1,500 rpm. When it wasnt producing any power you could hear it sucking air but there was no PSI. Has anyone else had this problem with their L200?

If the turbo is on its way out there is a good chance of alot of smoke. If you arent getting that then its more likely to be something like blocked filters, or given that it is intermittent, a piece of dirt over the pick up in the tank. That will affect the rev point at which the turbo kicks in too. I would do all the cheap bits first. Change all the filters, and take the pick up pipe off the lift pump and having removed/ loosened the filler cap blow back down the fuel line with a compressor. If you have a filter in between the lift pump and the tank, blow it back from the tank side of that filter.

Turbo on a rice rocket may be cripplingly expensive.....hope its dirty fuel related mate.

check for loose or collapsed/delaminated boost hoses

clean the egr valve, common problems with mitsi engines is that they coke up and you loose power.

It has just been booked into the council garage for friday afternoon so they can do the checks n sort it out over the weekend. I recon dirty fuel dilters may be the first thing to check and turbo the last. I think the last thing the boss wants to do is fork out £500 for a new turbo. We had the egr valve cleaned 6 months ago as it was fouled up. Probably be worth just removing the egr valve all together as it tars/gums up the valves n inlet manifold.

Poss air cleaner ? !

[Matthew Arnold]

Checked air cleaner/filter today and was ok. Obvious signs of dust but wasnt black with road dust.

[Pat Ferrett]

Any chance the bloke who borrowed it stuck a gallon of petrol in it by mistake ?

[Matthew Arnold]

Changed fuel filters on the truck and bled the system. Much much better. We have put half a tank of supreme deisel in and half normal stuff. Wait and see how it improves.

intermittant turbo problem points to all the above & a sticking wastegate/dump valve on the turbo !!!!!!!!!!!!!!!!!
