Gasket sealant. I just dont know!
Hello,
So i am not clued up at all about gaskets!
Not sure whats best sealant to use nor how much to put on!
Ive seen this
http://www.ebay.co.uk/itm/Heldite-Ga...ht_2463wt_1114
But not sure if it will do what i want it to do?
Or do i get something like this?
http://www.ebay.co.uk/itm/1-x-QUALIT...#ht_930wt_1114
I have all the inlet and outlet gaskets to do and i might do the one under the rocket cover.
Ive been told when using sealants just put a thin bead round then smooth it away with my finger
?? But the first one i showed you looks as if you kinda paint it on and whack the gasket on!
This does sound cow-boyish i guess but i want to do these things on my own without paying someone
Even if there was a video you can show me i would be grateful!
Thanks for you help

At work we use normal black rtv sealant but for some engine and gearbox work / warranty work we have to use the stuff daf say to use which is always one of the loctite sealers! Ive always been a fan of useing a bit of sealer

The actual flat gasket faces won't need any sealer if the faces are clean enough.
But it is advisable to apply a small amount of sealant on any joining edges where the gasket joins a seal or joins another gasket.

This sounds alot easier than i first thought!
By the sounds of things as long as i use a new good gasket then just bolt it up and your good to go!
Ive gone for cometic as i hear there good and reusable if ever needed, also you can bend them and use again Or so ive been told. Plus i like the feel of the sponginess!!

A bit of silicone sealer won't harm anything and if you use a clear one and only a smear will be unnoticeable. I put a smear on everything apart from heads that is.

I use stag wellseal:
Oil or Coolant, machined surfaces.
for non-machined surfaces I use Super RTV Silicone, Fuel resistant and oil resistant so safe to use on inlets.
Developed by Rolls Royce Ltd and manufactured under license, this compound is the complete answer to sealing problems on machined faces.
Stag Wellseal jointing compound is non-flammable, has easy partability and is non-hardening it is formulated to give the best possible sealing
performance under a wide variety of conditions.
It can be used to seal threaded connections as well as flat- faced joints and can be used with or without a gasket, depending upon the design of the assembly.
Stag Wellseal Jointing Compound is highly resistant to the majority of commonly
used field, lubricants and coolants and is non-corrosive and free from
abrasive fillers.
Wellseal will withstand temperatures up to 195?C (383?F)

My advice would be to clean the mating faces the best you can.If using a scraper/blade be careful not too gouge into them if aluminium.A slight bit of sealant wont do any harm if needed and in some cases will hold the gasket in place.Do not put loads on,when compressed it can go everywhere.The amount of times I have seen what looks like cheese strings in the pick up pipe strainer 
worse still it will block an oil gallery

That's the beauty of well-seal, it never drives like silicone, always stays kinda like teacle, so easy to remove something/clean and re-seal it using the same gasket for instance and no oil strainer issues!
