diesel Mechanic in Fredericton NB

[PostmanNB]

For the last 5 months my toyota Land Cruiser has been at a local mechanic, he deals with larger trucks and has only been able to look at it when he has time.

I made an an appointment with Clark Toyota in Fredericton and payed $200 to have it towed up there. The diesel mechanic says he does not no if he can work on it and the shop is swamped with dealing with the toyota recall.

Does anyone know of a mechanic in the Fredericton, New Brunswick area that has delt with JDM engine. I am frustrated and want to get this back on the road.

what is the issue now?

what is the issue now?

The engine has been rebuilt but is blowing grey smoke. The recomendation was that the head gasket was to thick, there are 3 sizes available for this engine. We did the measurement and found that we should use the B which was the thinner, this did not solve the problem and made it run rough. I have a D head gasket as well which is a the mid sized and I the plan was to try that.

The problem that I have is that my mechanic is swamped with work and can not get to my truck, he may be able to work on it for a bit and then have some logging trucks come in and my truck sits outside for a week.

I had it towed to a Toyota dealership that does have a diesel mechanic but the mechanic says he can't look at it claiming he can get parts and I should of replaced the 2L head gasket with the 3L.

If this fellow can't work on the engine I am going to have to find someone else, and I need to know if anyone knows of anyone who works on deisel Land Crusiers in New Brunswick

the head gasket will not cause the engine to blow grey smoke.
a thin gasket will give higher compression.
the thick gasket will drop the compression and give a feeling of lack of power.
the 3L or 2L gasket will not change the problem.

have the oil rings seated yet?
were the rings installed properly?

changing a head gasket is NOT cheap and NOT easy on those engines. i suspect both mechanics took one look under the bonnet and said "screw this, he can take it somewhere else" and are hoping that you will.

bring it back home, drive it for 5000 km. keep track of the oil consumption, fuel consumption, EGT readings, boost readings.

you are throwing HUGE money and time at this truck, i hope one day you will be able to post up:
"i am overjoyed with my truck as it has not cost me a dime in 2 years"

The massive grey smoke issue (I saw the video) may be due to a bad injection pump. It really looks like a combination of over-fueling and timing that is not correct - the pump and computer control both of those things.

So, if the valves are set correctly AND the injectors are tested to be spraying correctly AND there are no EGR problems AND the timing belt is not a tooth out AND the fuel is not contaminated with gasoline, then I'd be looking at the injection pump.

The 2LTE head gasket gets used with the 2LTE engine - you should not be putting a 3L head gasket on that unit as the bore is larger. The 3L head gasket will fit, but it will be expensive to do and pointless as the ONLY difference is the slightly larger bore. If the Toyota mechanic says you need the 3L head gasket because you have the "3L" head (in quotes because the head is interchangeable between the 2LTE and the 3L) then he really doesn't not have a clue, and I would be very suspicious of his knowledge base with this particular engine.

I, myself, am getting to the point where I am going to start refusing to work on these engines. They are very difficult (likely impossible) to adjust and tune because of the computer controlled injection pump, and when the don't work correctly there is only so much one can do.

Best of luck with it. And, if you're looking for a factory new pump I have a few here in stock.

John,
have you tried to put the mechanical pump on and get rid of the electronics?
maybe it would be a cure for a lot of issues with these engines... maybe not.

I finnally got a call back from Clark Toyota, he finally gave the truck to one of his younger mechanics to work on. The mechanic was able to figure out the problem with it revving of the engine he was able to get the proper configuration of the hoses for the vacuum. He checked the compression and it was OK.

He will be checking the timing on Tuesday and adjusting the injector pump. If there is a problem with the pump we have a used pump on the extra engine I bought.

The problem that he had with working on the engine was the fact that the HEAD was replaced with a 3L HEAD and I should of used a 2L HEAD. I was able to explain the problem with the 2L HEAD and why they replace it with the 3L

Just to be really super duper clear about this, there is no such thing as a different head for the 2L or 3L, they are the same item when we are talking about this generation of engine (the earlier 2LT engines used roller rockers instead of a bucket and shim design).

I spoke to your mechanic about some of the vacuum lines and sent him a photo of the intake on one engine, and he indicated that they looked like they were set up properly.

The EGR system can cause all kinds of grief if not hooked up properly - it is meant to activate only at idle and only when thee engine is up to operating temperature. The EGR should deactivate once the throttle is opened. Also, the boost hose to the MAP sensor (aka boost sensor) needs to installed properly for the 2LTE to deliver the proper. The MAP sensor changes the amount of delivered fuel by measuring manifold pressure.

Old injection pumps are old injection pumps... these electronic units seem to be a little touchy.

Hope you get things sorted out.

We installed a 3L-T into a Prado (auto trans) and it runs really well. The fuel economy isn't exactly stellar, but it has good power and it hasn't died from a cracked head (over 2 years now).

3L /2LTE never did have "stellar" fuel economy (how can it with 4.90 gears?) but that is good news for the owner...

congrats
