Wanted: Mkiv Engine

Hi Guys.

 

It looks my engine in gone and maybe it is cheaper to buy another engine. I need a 2JZ-GTE Engine with low milage. There is nothing engine accessories necessary. I have everything but I need a complete engine and a engine that runs well.

 

JAP or UK Spec isn't necessary because everything like injectors and Turbos will be used from my car.

 

Cheers

 

Peter

Hey Mike,

 

I don't know whats wrong but i think it is more expensive to find someone in Germany that opens the engine and take a look and repair it, that a exchange engine.

 

I check the compression in the next days. My single Turbo loses some oil after the Exhaust impeller and I removed it and found following:

I thought something is wrong with the turbo and the seals, but I have a DBB Turbo GT60 and PHR give me following info:

Hi Peter, the trouble is not the turbo or the seals, the DBB turbos dont even have seals like you think of them. There is only too much oil pressure entering the turbo, and its bypassing into the exhaust housing and smoking.

When you bought the DBB turbo, there was a .040" restrictor in the oil feed inlet to the turbo, was this installed? Also if this is a new motor, the oil pressure can be very high and cause the smoking also. There is nothing faulty with the turbo, just too much oil coming in. If you dont have the restrictor, you need to get one made up there or I can send one.

 

Thanks,

 

Jarrett Humphreys

 

I have checked something and I can't believe the Paul Whiffin have had anything wrong. He installed the setup. I don't know if I have this restrictor !! I found only that one into my oil feed inlet.

I have remove the exhaust turbo housing and found that horrible picture.

That crazy thing is, that the turbo don't scratches into the housing and have no bearing clearance.

 

The reason therefor is, that something come from the engine in the turbo and damaged the impeller.

 

What it is, I don't know but I can't find another reason for the damage.

 

:( :( bad days... this weekend

Hi Peter,

 

Have you tried Terry? He could get a brand new short block from Toyota for a cheapish cost...and that may at least mean that you can have faith in the parts (as they are brand new).

 

Thank you Alex,

 

do you have the correct Forum Name ?? I thought there are a much Terry's ? I don't know !

 

But the problem is, I don't know what is damaged into the enigine and therefor I think a exchange engine with head etc. (the whole engine) is better in my case

Ahh yes you need to do more investigation...a dropped valve or spark plug could have done the damage you've seen.

 

I meant Terry S...but if I was you I'd take the head off before buying anything.

 

I'm sure that you've got an oil restrictor on in that pic so thats not a problem.

Thank you Alex,

 

The crazy thing is, that there is no (absolutly NO) oil into the exhaust manifold. The oil is only after the turbo and the downpipe.

 

I think, that something is wrong in the engine and there are to much pressure in the crankshaft housing and the oil that comes into the turbo, doesn't go back into the oil pan.

 

You are right, that it would be better to open the engine and take the head off, but I can't do that and I know nobody in Germany that can do that and I don't like to give the car to Toyota. (That's is defenitly to expensive) If I live in UK i have more ways to repair the engine and maybe it is cheaper to got a engine from a chrashed car or something.

 

Maybe someone have an idea what could be the problem?

 

Cheers

 

Peter

 

BTW: I can start the engine and it runs very well without noises at the moment: Can't believe that. The Spark plugs are clean and OK. That's the reason, if I don't know what is wrong or if anything is wrong with the engine but anything must have damaged the turbo impeller

If it runs ok most of the time the oiling is likely to be cause when under load/boost.

 

Is the breather system closed? ie do the breathers off of the cam covers get piped back into the intak system?

 

As for the damage to the turbo can we be sure it's not been like that for a while?

Yes Alex,

 

the breathers go from the head to the air intake ( Paul did it ) but there was also oil into the pipe.

 

Here you can see the pipe from the camcover to the intake.

The reason i have take a look was unbelievable much blue/white smoke of the exhaust and that without boost and driving 10mph with absolutly cold engine.

Is the turbo oil and water cooled?

 

Before you buy a new engine make completely sure the oil housing did not crack anywhere and that a piece of the hosung did not make its way to the impeller..

 

That would also expplain the oil in the exhaust.

 

I was unlucky enough to have a faulty oil and watercooled turbo that ran perfect under idle but the minute the water system got under pressure it would leak in to the oil housing..

 

All together a very expensive exercise and a big waste of my time !

Thank you mate,

 

but must be the engine, because the first cylinder have only 102PSI compression and thats not enough.

 

Also we have found that the shaft from the turbo was damaged.

 

Worst case... Engine dead and the part that comes from the engine get into the turbo blades.

 

But i have sent the turbo to a specialist to check it.

EDIT: Thanks Alex for help...
