Small groove (hole) in inlet manifold?
Is there meant to be a small groove type hole near the right hand side of the inlet manifold? If, so what is it for?

Sorry - you are going to have to be more specific!
Do you have a picture you can show us?

Can't be sure without checking but I'm sure there isn't on mine. Looks like a casting imperfection to me

Both of my 1800 Gti's have had this,could it be to alow the manifold to expand when it gets hot?

We were looking at that on your manifold the other week Boogaloo. Mine (1600) has no holes :posh: . Only seen it on 1800's - could be a casting imperfection that occured during 82-83 manifold production? They've lasted 20 yrs plus so obviously no cause for concern.

My 1600cc GTI has the same hole.
Checking the VW parts drawing, there also seems to be a mark where the hole should be.
Strange.

Got one on mine. slightly bigger though. Have alway thought it was there as some form of drain hole in case the manifold webs/tracts got water or some from of other fluid on them for some reason and it needs to drain the fluid to the ground rather than just leaving it there :wink:

That's a good idea, BUT, there is only normally a hole between inlets to cylinders 1 and 2, plus, it would not drain to the ground, it would dump it on the exhaust manifold!
Agree with the majority though - casting imperfection - not an issue.
