A 1998 Volvo 850 Turbo Engine has been placed in my 1997 Volvo 850 Turbo. The car is sounding a little rough. Mechanic cannot detect what vaccum line is not closed up properly in order to stop the noise. Noise sounds like a muffler. Please help!

1997 VOLVO S/W 850 GLT.
P0243 TURBocharger wastegate solenoid a malfunction , HOW CAN THIS PROBLEM GET FIX .
THANK YOU

Check the fuel pressure regulator, it may have gone bad and running the engine rich. Good luck

This is for a 98 T5, but it should be close enough. http://www.matthewsvolvosite.com/forums/viewtopic.php?p=93956#p93956

check the thermostat, it's where the top radiator hose meets the motor in a housing

yes I do believe you can easily get 200k out of her. I have seen a few volvo's with over 250k on them. As long as maintenance is kept up, she'll keep purring

it should be a 2.4L with or without turbo

This is a common problem with all models of volvo, with the non digital odometer  pre 1998,, there is a tiny nylon gear deep inside the odometer that needs to be replaced. Your dealer will not fix it, but will put in a new one for you as the cost of fixing in labour is more than a new one,, My solution is much cheeper,, I have
many low milage VOLVO odometer/instr clusters, a few hi'r km 1s


ODOMETERS FROM 1987-PRESENT
I have many pre 1998 Volvo instrument clusters, most with Very low milage, almost all in Km, I have most models of Volvo.

at these prices IT'S A GOOD IDEA TO HAVE AN EXTRA ONE , comes with detailed instructions -with pictures-on how to remove your old one and re-install

just for example
I have 4,, 1994-1997 850/s70/v70 /c70turbo with less than 10,000 km
2 1994-1997 850/s70/v70/c70 non turbo with less than 10,000 km
1 1990 740 -940 turbo with less than 4.000 kms

I also have many Volvo instrument clusters from 1987 to PRESENT with varied milage,,let me know what year and model and milage you are looking for,, I will have something close

WILL SHIP ANYWHERE IN N.AMERICA

It's very common for the turbo return line seal to leak. That is what I would check first, when it leaks, it will spray oil all over the turbo lines and the rear of the engine.

There is a good chance it is the rear main seal. If this is a turbo engine, the oil return line seal from the bottom of the turbo to the block leaks also. Shop should be able to clean everything off and spay some dust on the area. Drive the car a few days, and take another look. You really need a lift to get a good look.

Sounds like maybe a freezeplug...definitely have to go to shop if that is the case.
