Which way round do gaskets go & do I use adhesiv

[Jolyon39]

Hi,

I have been cleaning up the intake on a standard 2.0L TR7 with twin SU's.

In the following photo I show that funny plat on top of the manifold. One side of the gasket is silver as you see and the other is a normal fibrous type material.

1. Should I use some sort of gasket cement with this gasket? if yes then what type of cement should I buy?
2. Does the silver side face the manifold or the blanking plate?


Also, I have removed and then placed the carbs back onto the rubber isolators on the manifold. SHould I use some sort of cenment with the gaskets that go between the carbs and that Link Plate (TKC1718)

Hi. No TR7 expert here but I'll give my opinion. That looks like an EGR block off plate. I would put the metal side toward the intake as it will be hotter. I wouldn't use sealer on any of these gaskets. Just make sure the surfaces are clean.

Thanks Underdog,

I your advice sounds very right to me, metal to the hot side!

EGR valve huh... I could not understand why they had this blanked off connection here. We have no emmissions control stuff in NZ so I have not encountered that before.

To further expand:
Metal side of gaskets against the hot side to reflect heat.

Both surfaces sould be clean (of grung, old gasket, old glue etc.). Gasket remover can help here.

Gaskets in contact with gas (as in carbs, etc.) shouldn't have sealer.

Spray on tacky gasket goo can be sprayed on one side to hold the gasket in place when fitting. Example; valve cover gasket, sprayed on valve cover side. It's usually sprayed on weaker part.

If surface is not smooth or it's warped (example, over tightened oil pan (sump), thicker goo may be needed to make a leak proof seal. If too bad even that won't work.

When tightening parts together tighten screw (bolt) until just touching then go around in criss cross pattern gradually tightening screws until torque value is reached. Parts with high torque values (example, head) will have actual tightening patterns that must be followed.

These rules are not something I have neccessarily read but have used to success and make sense to me.
