Thanks for the mention, Rick.

Due to some minimum quantity requirements, I have just a few of the 948/1098=
 and 1275 kits still available.=20

Provided there=E2=80=99s not so much wear on the main cap/half moon that the=
 tolerance is beyond the scroll function working correctly, setting up a Smi=
ths PCV will indeed help minimize, if not cure the leak while the engine is r=
unning. Otherwise, an align bore to restore air gap tolerance is the only re=
medy until it wears again.=20

The issue with the other kits commonly available is that the air gap, which s=
hould only be a couple thousandths, is increased to over 1/4=E2=80=9D (over t=
he diameter). In other words, the scroll function is completely discarded/no=
t functional. At some point, the lip seal becomes overwhelmed with oil and i=
nternal pressure pushes the oil out anyway. My design not only retains the s=
croll function but also restores the correct tolerance without machining. Th=
ere are several other superior design features that improves fit and functio=
n.

An extensive review, explanation of installation, and endorsement is availab=
le at the link below.

Anyone interested can send me an email for more information or interest in a=
cquiring one.
