Flame Trap Relocation Kits

A. B.
Volvo uses a small, in-line filter to manage positive crankcase ventilation on their 4 cylinder engines. The ventilation system incorporates a small flame trap filter to protect against possible crankcase explosions due to a backfire. This filter is overlooked in most workshop manuals, and, without periodic maintenance, it will plug up with oil deposits and cause excessive crankcase pressure, which, in turn, will cause significant oil leaks all over the engine. An additional contributor to this problem is the fact that on these models, the filter and filter holder are buried below the intake manifold and are pretty tough to access (see photo 1).

Beginning with 1988 models, the filter was relocated above the intake manifold for easy access. Our kit includes everything you need to convert your Volvo to the new configuration, including detailed instructions. This turns a job that can take up to an hour on some models into a 5-minute service. We recommend checking the flame trap condition at every oil change. Please note that it is possible for the crankcase ventilation box mounted on the engine block to be plugged up in rare cases. We have these available as well.

Flame Trap Parts

When servicing the flame trap system we generally recommend that you use one of our handy flame trap kits, as most of the parts will be in pretty rough shape and often crack upon disassembly due to the harsh conditions they are subject to. However, if you do need a single part or two, we also offer the parts below individually. Please note that these parts do not fit any V6 engines. Flame trap insert not used on turbo models.
