Oil sump gasket

[thorbs000]

Hi all

It's a stupid question I know,but what is the best liquid gasket to use when putting the sump back on the engine?
Do you put the sealer on both halves?
I have read loads of threads already but it's just confusing me. The engine is out of the car and upside down so no access problems.
Also can I use the same gasket sealer on the rear crankshaft oil seal carrier?

Just remembered,there aren't any stupid questions on here,are there.

I have always used Loctite No3 aviation gasket sealer on the sump cork and rear carrier seal paper gasket. I apply both sides and allow it to go tacky before assembly to hold the gasket in place, assist the seal and help the cork gasket not get squeezed out.

Loctite 534 is a recently introduced anaerobic high tack stick applied sealant that I have not tried yet but is intended to achieve the same outcome and looks easier to use potentially

I have never been able to find a supplier of Loctite No3 aviation gasket sealer here in the UK is there any similar or alternate product sold in the UK.

Ditto, another vote from me for loctite 3. Also important, I've found, to "flatten" the flange where the bolts go through with a hammer and suitable dolly.... for some reason the hole edges often end up protruding over time. I also stick religiously to the torque setting for sump bolts, a smidgin more and it can split the cork. I'm sure one of us could arrange to send you a bottle of this stuff if it's genuinely not available in UK. Would need to check the company's data sheet however, to make sure it's not volatile, in which case airmail is a no-no.

Most bearing supply places here in Australia carry the full range of Loctitie products or can order it in if they dont have it on the shelf so try there. Loctite may sell it under the Permatex brand in the UK also.

I think the blue Hylomar is similar in properties to the No3 but i have never used it so not sure.

i have used with success Loctite 5920 (old ref was aj66) gold

Hi all

Thanks for all the advice. I went with loctite 5920. Job done. On to the next one.

I would just use a little of the 5920 Copper Max in the corners where the front and rear seals around the crank join the flat seals on the block. It is not a good adhesive and does not really help prevent the cork gasket being squeezed out. You also do not want to use to much as the silicone gets squeezed out and can block oil passages

Rohan,
you are right, it can have a tendance to squeeze the cork gaskets out

I found this product on UK ebay could it be an alternative for Loctite No3
Pematex High tack gasket sealant

Yes it certainly looks a suitable alternative for keeping the cork gaskets in place during assembly.

I took Steve WW's (who used to post) advice. Do it in two stages. First to the block. Then let it go off and then return the following day and remove and do the sump side. I have done it 3 times now, works a treat with none of that oozing and slipping lark. Mike
