Since every manufacturer can use whatever color they want to create their flavor of gasket material. RTV or Room Temperature Vulcanization sealants come in many types, colors, flavors, and work to seal for many different occasions. Also remember that each manufacturer may utilize the same color for different means. Black sealant is very commonly used in the ...

I made a gasket for a small single cylinder engine from a copper sheet. Annealing and making it fit are obvious... But it worked perfectly. Would I use "goop" - no. Making a paper template is handy, I have had success with laying suitable brown paper on to the block or head, sticking with grease or similar, then tapping gently with a tiny hammer to break ...

Not for a head gasket. These are typically covered with a thin foil that resists the high temperatures of combustion or are made from a heat-resistant material. They are alo thicker that basic bulk gasket material and you could be artificially raising the compression ratio with thinner material. Get the right gasket for this. Generic gasket material or ...

Rubber gaskets typically seal well. Cork ones are hit or miss. If the valve cover is stamped steel, its normal to use gasket maker rather than the gasket. If a piece did fall off inside the engine, the oil would likely flush it down to the oil pan and it would be caught in the oil pickup's screen.

They are basically the same thing. Use the gasket and put the gasket maker on either side of it. It will do the same job and work just as well. Don't put it on too thick, just enough to hold the gasket in place on the block or on the pump. Should leave you in good stead.

As an AZ shop owner for 39 years, we use blue silicone for typical gasket connections AND any cooling system or water system connections. We use red for exhaust manifolds and exhaust connections. We've never seen an O2 sensor that died because of silicone contamination. An O2 sensor is a battery, someday it will die just like the ones in your flashlight. We'...

All silicone is anerobic and dries/hardens due to the lack of moisture. ultra anything by locktite is sensor safe,red,grey,blue,black. Proper use is not only dependant on the fluid to be sealed, the pressure has to be included, i.e. turbos.Ggaskets and sealants are equals and combined properly are the state of the art. Combined halfassedly are shit. Learn. ...

It is not going to bother it too badly. It can cause issues if you get too much into a hole. As was already stated, this can cause breakage of the block. It's called hydraulicing. I don't think you could get enough torque on these smaller bolts you are talking about to cause you any issues as the bolt would break off before it would get that tight. I have ...

If you get lots in and put the bolts in, it is possible that you could crack the head/block around the bolts. A very small amount shouldn't do any harm, but could possibly affect the torque setting. Best not get any in, though.

To answer your questions: Ignore colors--check specs online before you shop. Colors change by brand. Specs other than temperature rating: - full cure time - return-to-service time - fluid type resistance* - tighten-wait-torque vs torque-and-done *Don't get too hung up on all the types. RTV for transmissions will be perfectly fine for your water pump. I ...

The right stuff is very dense silicone and doesnt flow well. But probably is the most common go to. a type i didnt see in you list , flowable silicone very thin fluid like silicone comes clear and is marketed to seal any gaps in winshield seals. Ive used it to seal roof repairs on some campers. Depending on the material. But i guess it works when used. No ...
