the turbo is fine and all..some guy who had a newer volvo way newer told me that his did that too..

 

tech, what do you mean by seized?

 

Remove the hose to the turbo and try to spin the turbo.
If it spins good then it is fine. If it won't move then it is seized.

 

hey do you know the engine reset code for a 2001 volvo S40?thanks

 

The service light or Check Engine light????

 

Alright here's a tough one. I have a 1988 740 turbo, but recently I had to replace the engine. My mechanic replaced it with a non-turbo model. The engine runs pretty good except that he couldn't hook up the "check engine" light. It seems that there is a problem hooking up the on board computer. My local Volvo guy doesn't want to deal with it. He says that to fix it is going to cost a bundle. Any suggestions?

 

That sounds like a nightmare.
BUT
1.Why did you need a new motor?
2.If you install a Non-turbo motor without the computer then it will almost never run right.
3. Why didn't he install the Turbo head on the Non-turbo bock and install the motor as a turbo?
4. Or even the worse you could have installed the Turbo cam in the Non-turbo head and stil run it as a turbo.

 

The old motor had two dead cylinders. The mechanic said he thought the turbo was part of the problem. I'm thinkin' he just didn't want to deal with installing the new one.

 

I doubt it.
He had more trouble converting it to Non-turbo than he would have had just putting in a turbo motor.

 

I have a 86 Volvo 240 SL. I was wondering what is the purpose of the hose running fron the bottom of the intake box the the exhaust manifold?

 

It is called a Heat Rise tube.
It is used in the Winter in Cold Climates to Transfer heat into the air box for the engnie to warm up faster.

If you live in a warm climate then there is no need for it.

 

what procedure for head removale on 2000 s80

 

Hi

I have a D24 TIC motor, and wondering on what things I can do to get more power from it. I have changed the diesel pump from 2,4l to 5,9l, and having 3-4 bar on the turbo. What more can I do?
