Loctite 515 anaerobic compound, specifically formulated for sealing
flat flanges on machined surfaces. This product has high surface adhesion
properties, which will assist in holding a seal in the housing or mating two
surfaces together. High viscosity prevents migration of the product from
the sealing surfaces during assembly and cure.
Preferred in many industrial applications and aerospace. My favorite for
resealing cam
towers on 900 series engines (Lotus recommended & hard to find).
This purple anaerobic gasket maker has an effective near-zero sealing
clearance allowing for valve shimming to the same specs as a dry fitting.
Takes the headache (almost) out of valve adjustment (no need to figure
in gasket thickness). Heafty 50ml size is good for 3-4 changes. Cleans
up with laquer thinner. No curing time needed, install and drive away!
The best, accept no sustitute.
Also excellent for joining the main bearing ladder to block and other
engine/mechanical joints or surfaces requiring no gap.
Warning: don't use the original cam tower gaskets that may come with your
Lotus gasket set! These are junk and will only lead to a oil leak condition
later. Lotus has several service bulletins that recommend that they not be
used and that anerobic sealer be used in it's place.
