1993 940 Head Gasket bolts, reusable or no?

Post by **98T5** » 01 Mar 2014, 21:50

I found out today that I have a breached head gasket slowly peeing oil into the water pump, and thus into the expansion tank. I took the engine down to the head gasket today and yes the gasket is toast, and the breach is right there at the water pump too. My question is this, Can I reuse the head bolts or no? I have the head gasket kit on order so by the time it gets here I can know for sure.

Thanks for the advice.

This is what I found from a Google search:

For the B230 and B230FT engines the head bolts can be reused provided the length does not exceed 55.5mm (2.187 inches).

The head bolts can be re-used up to 5 times if they are not stretched.

One very important point with Volvo heads is to check them for height and warpage whenever they are removed. This is best done by a machine shop with the correct tools.

The head height must be at least 5.752" (146.1mm). If it is less than this it cannot be re-surfaced.

Using a metal straight edge check crosswise and lengthwise. Maximum warpage allowed is:
Crosswise .02" (.50mm)
Lengthwise .04"(1.00mm)
Outside of these tolerances you must have the head re-surfaced.
