Liquid gasket

What level of imperfection can a liquid gasket tolerate!

I have a transmission oilpan that is pressed steel bolted to cast aluminium.
It is designed for aliquid gasket sealant but seems to have slight irregularity where the bolts go through the pan. A straigtedge shows a sliver of light between bolt holes on the mating surface.

Should be fine. Whats more important is that both mating surfaces are surgically clean, and that the sealant is given enough time to cure properly before adding fluid. Very surprised that a liquid sealer is recommended on an auto, it usually isn't because of the possibility of excess sealant getting into the hydraulics.

put sealer on put bolts om and only tighten to slight squeeze , let dry and then tighten fully . thats how its done with the red goop sealer. otherwise you be pushing chunks in to the sump when you tighten it when its not dry

Thanks guys,
I went to the dealer to buy a gasket before I had removed the oilpan and they informed me that it was a liquid gasket.The service manager had a quick chat to me about it when I expressed my surprise.

Maybe an aftermarket cork one is available. I will check around.

+1, fantastic product.

Not unless you want to wait 24 hours for the stuff to cure properly, especially where ATF is involved. Wurth make an equivalent product thats just as effective with a way quicker cure time.

A worthwhilepoint; I must say however that I've had fantastic results using 3 Bond in race engines over the last decade or so. Waiting 24 hours is a small price to pay for the performance it delivers, I just whish the bloody stuff wasn't so damn expensive!

Lol yeah so do I. It is a good product and a heap stronger than normal hightemp silicone, BUT have seen more than one job stuffed up and had to be done again because the oil weeped past uncured sealer.

Sounds like we're on the same page here mate. It's hard to get the info over in a few lines on a MB but as you've undoubtedly found, with a little experience using a file to carefully remove any raised edges around threaded holes (particularly in aluminium) and sometimes a little panel beating of pressed steel covers you can make some big gains in getting things oil tight.

I did the job this morning, and am waiting until late afternoon before I tighten everything up. The dealer gave me the tail end of an aerosol applicator bottle of Wurth sealant for it, very sticky stuff.
I cleaned all the surfaces with some MAF cleaner spray and a scotchbrite pad, it ended up surgically clean as recommended.

Thanks again.

I used it on a 6pstdh Daihatsu crankcase doors and it worked like magic. The white 1211, put it on and leave it 5 minutes or so.
