Permatex Hylomar or Permatex Ultra Copper for coolant seals + other areas
Hi .. im just about ready to reassemble my engine and i ran out of RTV black ( i use around the dowel pins , around the legs of the housings and the rear stat gear flange ) ... i went to the store and got this :
http://www.permatex.com/products/Aut...sket_Maker.htm
OEM specified. Highest operating temperatures for 4-cylinder, turbocharged or high-performance engines. The most advanced, high temp RTV silicone gasket available. Sensor-safe, low odor, noncorrosive. Superior adhesion. Three times more oil resistant than conventional silicones; eight times more flexible than cut gaskets. Temperature range -75°F to 700°F (-59°C to 371°C) intermittent; resists auto and shop fluids and vibration.
i was simply wondering ... is this somehow better that what i have always used for the coolant seals grooves? ??? which is of course :
http://www.permatex.com/products/Aut...ge_Sealant.htm
This non-chlorinated gasketing and sealing compound has been specially formulated to be non-setting and non-hardening at elevated temperatures. It withstands rapid changes in temperature and remains flexible and tacky even at high temperatures, allowing repeated disassembly and reassembly in high performance applications. This no-run formula seals surface imperfections on machined flanges and is vibration resistant. Temperature range of -60°F to +500°F (-50°C to +260°C); resists engine fluids, including water, coolant, gasoline, lubricating oils, kerosene and some refrigerants. Also possesses dust and moisture proofing properties.
the ULTRA COPPER seems to share all the bells and whistles with the RACING BLUE .. but seems to withstand higher temp : COPPER : 700 F vs. BLUE 500F
will this seal small imperfections in used plates/housings as well as hylomar blue ?
i have both handy ( couple of tubes ) .... which would be better for resealing an engine :
coolant groves
rotor housing legs
dowel pin areas
rear stat gear flange .. etc
front cover
etc
also i dont want to use it on the oil pan area
thx for reading
