Diesel pump leak, fixed now turbo not kicking in?

Home  \  Repairs & Maintenance  \  Diesel pump leak, fixed now turbo not kicking in?


I had 3 quotes for my pump leak

£700, £1000, £90

I chose the £90 option, as you would, anyway the guy told me that he needed to change 2 seals on the pump, one of which is the choke seal, and the other I presume is the pump seal.
He changed them and now the Turbo isn't kicking in, lack of power, I went back to him, and he wants nothing to do with it, he told me he only changed the seals and he didn't touch the turbo. I took it to a different place to have a look, he had a quick look, he lifted the seat and pulled the choke to full revs, he also took the pipe off that comes off the pump, when he took the pipe off and rev'd the green turbo light come on at 4 000 revs, I took it for a spin, but the turbo light never came on, I rev'd hard, I got back home rev'd it the same as the guy in the garage did, and again the green light kicked in at 4 000 revs, somethings not right, can anyone help?
Is it possible the seals are the wrong type?

Please let me know, cos I don't fancy forking out a lot of dosh!

Car is a toyota estima, Japenese import.
Automatic transmission

Mechanical skill rating, useless
Jobs done in the last year 11000km done

cambelt change
full service
2 oil changes

Sorry, didn't mean to offend!

Disclaimer: While the following guidelines cannot cover every situation, by using them and applying some good old fashioned common sense you will find your experience in this forum, and all the rest of the forums for that matter, a much more pleasurable and productive experience.

1. When asking questions about your car please provide year, make, model, engine size, and transmission type as a minimum. Of course any other pertinent information will be needed as well for example, if you have trouble with an inoperative window we need to know if they’re power or manual and knowing if it’s a two or four door may be helpful as well.

2. If there have been any repairs or maintenance performed on the car recently, this may be important so let us know. Also, if there is any past history of this or a related problem let us know that along with what was done to resolve it in the past.

3. Do not assume we know what you know or what you mean to say. We are more than willing to help but can only use the information you provide. Because we are online in a forum, we cannot see your face, hear the inflection in your voice or see, touch or hear your car. You are our eyes and ears and solving any problem begins with you and the effort you are willing to put forth helping us to help you. This brings us to…

4. The description. Please do not interpret what is going on with your car, just give us an explicit, step by step description. We need to know anything that might be a factor such as engine hot or cold, vehicle speed, weather conditions, etc. There are too many possibilities to name them all but you get the idea. Also, if you have already had the foresight to retrieve computer codes (in instances were that is helpful) let us know what they are. If you tell us you think it needs sparkplugs then your answer will be put in sparkplugs. Keep in mind if you knew what was wrong you probably wouldn’t be here asking for advice.

5. Another assumption you should never make. We don’t know who you are or what your mechanical ability is, your knowledge level or what type of tools, equipment or work area you have. Some repairs require very little knowledge but are labor, equipment and space intensive. Other repairs require very little actual work but you’ll need a large amount of experience or technical knowledge. Most repairs are somewhere in between. Help us out by honestly assessing what you can and cannot do and let us know. Claiming to have a higher knowledge level than you do is not only frustrating and counter productive for everyone involved, it’s also extremely transparent to those who have that knowledge and only serves to make you look like a fool.

6. Finally introduce yourself. There is a section here at Car-Forums.com called “Introduce Yourself”. We don’t need your name, age, address, social security number and date of birth although if you want to share those details feel free to do so. It is nice however to know a little bit about the person who we’re trying to help. And honestly if you don’t have the time to type a few sentences about yourself, then we don’t have the time to help you. Remember you came to us looking for our years of knowledge, training and experience.

I think that about covers it. Welcome to the Car-Forums.com Repairs and Maintenance section. We hope you enjoy your stay.

I forgot to mention in my original post, its a 2.2 turbo diesel toyota 8 seater mpv.


When I start the engine, both the orange light and green come on the dash, my estima will not hit 4000 revs, it gets to 3000 and changes gear, I just slammed it down the motorway, the turbo light still will not come on.

Also going up hill is a battle, no power, had to manage with 30mph to t5he top of the hill?

So what could it be?
Someone must have some idea!

Hi, I have an idea as to what the problem might be, are you sure that when you had your seals replaced the Mechanic didn't mess up a little bit causing it to leak diesel? because if you have a slight diesel leak and air is getting into the fuel system it'll seem extreamly gutles..as it would without a Turbo. Does it always start? and does it seem at all lumpy..so to speak? lol :thumbs:

Thanks for replying

The car at the moment starts first time.

It feels flat as a pancake going up hills.

When it changes gear it seems to take too much time, if it was a manual I would have changed gear before the automatic would have.

Let's pretend there is air in the system, what would cure it?

It might not be the answer, but it's better than no answer, It surely cannot be anything serious as the turbo was functioning properly the day he had it, it is only when he replaced the seals, problems arose

If there is air in the system..which may have happened during the seal replacment, it can usually be cured by bleeding out the system, this is sometimes done automatically by the car itself. However, if you need to do this manually there is usually a small bleed nipple on either the very top of the engine..(near the glow plugs) or near the fuel filter, this will not be easy to spot though, and if I were you I'd take the car back to the halfwit Mechanic who supposedly repaired the car in the first place and demand he check it for you..Good luck

Cliffy, that wasn't the problem.
People are baffled, which worries me abit, the gear change is only 1st-3rd (auto), I have an autogear guy looking for me, he told me to look at the potentimeter, I did but couldn't find any problem, he did say the gears where all over the place and that the car wasn't doing stepdown. He can't look at it till at least next friday, what I don't want is a big bill.
The guy who done it doesn't think I need my pump calibrated, he did take the potentiometer off when he was doing the leak, apparentley it must be set at a certain angle?

If anyone has any ideas, just drop a post
