In 1997, I split the exhaust manifold on my olde MD17C. It was my fault.
The cost, then, was £1300, then about $2200, FOR AN EXHAUST MANIFOLD FOR A 20 YEAR OLD MOTOR.
A piston and liner kit, you need three of them, each £300, then $510, total $1530.
Final drive oil seal, one of, £49....sourced elsewhere fo £3.50 (ABC in Aberdeen, Scotland).
Volvo would not seel me oversizes to rebore the motor.
Check out the price for their starter motor too.
Don't learn this lesson the way I did.
Don't buy one. I will never buy another.
Are you listening Volvo? Do want the details?
Expletive to the lot of you!
