Putting the new sump back on this week - gotta buy some gasket goop for the sump - what do people recommend for a CA sump?

Service manual states it should be 3.5mm-4.5mm wide, and to use geniune liquid gasket or equivalent - so keen to hear peoples experience as to the best 'equivalent'.

well i used permatex ultra black on my diff, that leaked after a week, and i treated it properly too, cleaned it and everything.
at work we use loctite black maxx, thats good stuff, still going strong on a customers car after 200000ks

Locktight stuff is ####. Smells like vinigar and is real oily. Probably sticks as well as vinigar too.

What we use at work for sealant only jobs is the Toyota genuine stuff. Its not that expencive from memory. Its black and its really sticky. If you get it on your hands you end up coating everything around you in black sticky ####. Or weve used the VW genuine stuff and i think it was the same stuff.

PERMATEX #3 AVIATION I have used nothing else in 35yrs of working on machines. I will never submit to using any silicone products. Seen that crap block oil galleries and blow up bits. Serious Face!!

i treid making a serious face once... ended up making a serious mess in my pants

stay away from silicon branded stuff. i couldnt even get their gasket maker to make a water tight gasket on the thermostat housing, then used some other stuff and never leaked a drop.
cant read the brand as its coverd in gunk from squeezing too much out,

Permatex #3 - got some of that - I've used in on the two rubber seals on the front and back of the sump, I didn't think it looked solid enough to form a gasket between the sump and the block though.

So just to confirm that is Permatex #3 by itself with no gasket between block and sump?

So the options are:

Permatex Ultra Black Maximum Oil Resistance RTV Silicone Gasket Maker
Permatex
Suggested Applications: Valve covers, oil pans, intake manifold end seals, timing covers, transmission pans

Loctite
Loctite

all loctite products are great

i would use a loctiite silicone product

i have used the loctite copper silicone on the exhaust housing flanges of my turbos without any leakage. it is awesome stuff, better than any gasket

lagwagon also gave it a shot on his sr20det turbo manifold flange and he told me it lasted longer than any gasket he has had in there, not sure how long he had it in there in the end but knowing him he has changed the turbo 20 times by now

i also used the typical blue or red loctite silicon on my sump with no trouble

permatex ultra copper, we use a honda genuine sealant at work.

permatex no.3 will not seal a sump it is generally used on thermostat (coolant) gaskets it does not actually set and you will never get it to 3.5mm

Silicon is no good, can block oil passages.

I just use aluminium spray paint on head gaskets.

Use this on everything else.
