Valve Adjustment/Decarbon Gasket Kit

 

This kit is for ONAN "B" and "P" "Performer" series engines. Included will be the needed gaskets for de-carboning/cleaning, piston, valves, head, and adjusting the valves in your Onan engine. This kit includes two USA made to our specs valve cover gaskets, two high-quality head gaskets, and two USA made to our specs intake gaskets that are cut correctly.

 

If you prefer the OEM ONAN head gaskets there is an option to switch to OEM for an added amount at checkout.

There is also and option for the USA made to our specs carburetor add on gaskets. Depending on your carb and intake you may use 1 or 2 or all 3 of these gaskets

 

NOTE: You will want to make sure you de-carbon and clean the heads/valves/piston before doing your valve adjustments
