​Hi Guys,
Has anyone fitted the replacement aftermarket aluminium oil pan gasket? (See link below)
[SIZE=+1]Obviously it doesn't distort and it supposed to eliminate oil leaks. You install by using gasket goo both sides then torque it down to OEM specifications.
I am about to fit aftermarket headers so I figure it is a good time to refit and hopefully forget any troublesome pan leaks.
 Thank you in advance, TYSAMA.

It comes in blue,black and red ,probably different heat ratings and is a silicon (i think ) gasket making material that comes in squeeze tubes.many people use it instead of a gasket. Many people also use both the RTV and a gasket.hope it helps....steve
 
Yes what steve k said. I would use high temp. Never been to Australia but our auto stores carry it. Just HIGH TEMP RTV Gasket maker. Don't over do it though. Just stick approx 1/8th Inch thick continuous line all the way around going on the INSIDE of the screws down the center between screws. If you use a gasket it is a bit over kill to RTV both sides all around I would however stick a dab on the corners to hold the gasket in place while installing to make it easy. This is if the Oil pan and surface it mounts to are flat and fit together as i just noticed that the NSX pan seems to have little bubble protrusions so if they dont fit flat together i would buy a gasket.

The pan in the pic is obviously not NSX but it is an example. The bead looks a bit thick on it and very uneven and not continuous but it shows an example and I'm sure that would seal it I'm just a bit of a perfectionist at this we use it on our airplanes regularly to seal gaps on antennas.

Thanks Guys,
Your right Grimeas, with the NSX set up you need the gasket thickness. Problem is the OEM rubber gasket distorts even when you torque it to Honda's specifications.
You can do everything right with a new gasket and it will still leak. Then with headers fitted it becomes a major job to rectify.
My thinking is that with a combination of the aluminium (No flex/distortion) gasket and a light smear of RTV (Both sides) it should form a permanent seal.

The NSX pan has dimples at each bolt location that prevent the gasket from moving and also make it so you must use a gasket, the RTV alone will not seal the pan. I use a very small amount of high heat RTV to hold the gasket to the pan, let it dry them install the pan. this keeps the gasket centered on the dimples during the install and torque process. You also need to inspect the pan very close to make sure that the dimples have not been crushed by someone over torqueing the pan bolts. You could also add a light thin film of RTV to the block right before you install the pan.

I looked at the link you posted but I was not able to see the product they are selling, a solid gasket with the dimples in it may work but the pan is not what I would call a precision part as it is only stamped into shape so any veriations between the dimples in the pan and the hard gasket would not likely seal correctly.

Oil pan gaskets can be a big pain to get sealed, some go easy and others are major problem childs. It does suck having to redo your work when one is being a pain. I would stick with the OEM gasket and follow the owners manual, add the RTV as another layer of protection and hope for the best.
