Lessons from 200K miles on a 1994 850 NA

Going the distance with a 1994 850!

Evidence Volvo’s Inline Five is (Near) Bulletproof

An MVS member’s findings upon taking his engine apart at 200k miles

To make along story short, a small piece of an exhaust valve on Cyl3 broke off. We took the head apart and found that actually the seals were bad. Probably the valve broke due to a piece of carbon build up that got on the way when the valve closed. For an engine this old, running with a 25% ethanol content gasoline, the amount of carbon was comparable to much lower mileage engines. No oil sludge of any kind, cams are perfect, valve lifters are perfect. Very small amount of carbon like material on oil passage ways. Head gasket looked like new. Coolant passageways clear and clean throughout.

Bonus! More on the Volvo 850

Volvo unveiled an entirely new model series in June 1991, the Volvo 850 GLT. The Volvo 850 GLT was launched under the banner of “A dynamic car with four world-beating breakthroughs”.

The four new features were: transverse 5-cylinder engine driving the front wheels, Delta-link rear axle which combined the dynamics and ride comfort of independent suspension with the security of a live rear axle, the SIPS integrated side-impact protection system, and the self-adjusting front seat belt mechanism.

The exterior design of the 850 bore a strong Volvo identity, and its 740 and 940 heritage was immediately apparent.

Volvo 850 GLT received a tumultuous welcome; seldom has a new car reaped so many awards as the 850.

Over the intervening years, the 850 series has been expanded with additional variants, among them turbocharged petrol versions and a direct-injection turbo-diesel.

The Volvo 850 was also the first car in the world to offer side-impact airbags, which were introduced in autumn 1994.

In model year 1997, the S70 replaced the 850 Sedan car.
