1994 BMW 740i Problems

Suspension & Steering -- Verified

A fluid leak may develop from one or more power steering hose. When a leak is being repaired, it is not uncommon for multiple hoses to be replaced.

Engine -- Verified

Engine oil leaks commonly develop from both valve cover gaskets, intake manifold, and PCV plate after about 60,000 miles.

Suspension & Steering -- Verified

The front thrust rod bushings—also referred to as tension strut bushings—are known to fail occasionally. The oil-filled rubber mounts weaken and crack over time, causing a mushy road feel and shuddering in the steering wheel when going over bumps. These worn bushings should be replaced.

Engine -- Verified

Leaks are known to develop in the cooling system. It is common to see more than one part recommended for repair/replacement due to overlapping labor and the use of many plastic parts in the system.

Engine -- APmech.

I put 161K miles on my 94 BMW 740I up and down a mountain, The ultimate driving machine is not a joke. I've driven a 320 Mercedes but nothing matches. The Mercedes floats on the freeway "a few" miles over the speed limit. The BMW with its 2000 Psi hydraulic pump for the suspension and steering lowers the vehicle 1/2 to 1 inch and the steering and suspension gets stiff this keeps you in touch with wheels to steering to the road sensation.

Summary: THE CRUISE CONTROL AND THROTTLE CABLES ARE ATTACHED TO THE SAME THROTTLE VALVE ACTUATING LEVER AT THE THROTTLE HOUSING.

it's a greate car

I put 161K miles on my 94 BMW 740I up and down a mountain, The ultimate driving machine is not a joke. I've driven a 320 Mercedes but nothing matches. The Mercedes floats on the freeway a few miles over the speed limit. The BMW with its 2000 Psi hydraulic pump for the suspension and steering lowers the vehicle 1/2 to 1 inch and the steering and suspension gets stiff this keeps you in touch with wheels to steering to the road sensation.

I am however heart broken when I blew a head gasket, As an aircraft mechanic I figured I could do it and to my surprise the car is well engineered. Just mark everything, use containers and label them, take pictures as you dis-assemble just to be sure. Most important get the $110 manual. The other point is special tools, don't worry you can improvise and you may need to make a couple of timing blocks for the camshafts.

My problem here and now is after it was all back together It was running like the timing was incorrect, so I double checked and again and again, then found my oil level sensor had burnt wires and was no longer registering a 1k ohm resistance. called and found $400 cost for a new part. Went to the junk yard and with an ohm meter and 10 mm wrench, paid $17 for a used one. Now my $150 diagnotics tool does not work and I am at a loss. Thinking it is my EC module, no break out box to check it.

Anyone have any ideas?
