Greetings All,

Let me say first that I just picked up an 85 740T and love it, but there are a few small things that need attention, and would love any help/suggestions that any of the Volvo experts here could offer!

I can not seem to figure out how to adjust the driver seat height. I checked for a lever on the inside of the seat neat the barking brake, but had no luck. The bar under the front of the seat works to slide the seat forward and back but that does notihng for the height.

One of the passenger side doors makes a loud pop when it moves from position to position to closed. It looks like the wheels that guide the movement might be rusted, but I am not sure.

Lastly, I have noticed occasionally when I floor it a cloud of exaust comes out the rear of the car from the tailpipe area. Is this just the turbo venting at high rpm?

Thanks so much for all your help!

I have a 1986 740T. The seat is adjusted by moving the lever and moving the seat up or down in front or in back as required. It's a simple mechanical system so there is not much to it.

Look at the 700/900 Maintenance FAQ via the link below. It is culled from previous postings. There is a section on buying an older 700 and what needs to be checked. Pay attention to the relay resoldering info. They will fail and can leave you stranded. Don Foster is the relay resoldering king.

If you have black smoke under boost, it indicates a pressure leak. Check all hose clamps for thightness and breaks in the connecting hoses. Any hose breaks will not show up under vacuum but will leak air under boost. The FI system determins the amount of air needed and injects fuel accordingly. If some air leaks out, you have a rich mixture.

Please pay attention to the trouble spots and fix them asap. My car has the original oil 'cooled' turbo at 254,000 miles. I printed out the FAQ and put it in a binder. I am amazed at the size increase sine the last time I printed it out.

BTW, how's your engine wiring harness? Check the black wires where they connect to the intake manifold. If the insulation is comming off, you have the original harness, which is what we affectionatly call a biodegradable engine wiring harness. Mine had it, I replaced it. It can be rewired by you for about 20 bux.

Fill us in, we like feedback.

On the 85s the height adjustment levers are buried under the seat.I don't remember exactly what they look like but there is one in front up above and behind the for/aft slide bar that controls the front of the seat and one at the rear of the seat that you have to access from the rear floor that controls the rear of the seat.They can't be operated while sitting in the seat.

Thanks for the heads up! I will check that out after work! I guess if it had come with the owners manual I would have been able to discover that!

Thanks Again!
