Like it says, (I LOVE the search funtion!) 846 hits, 18 pages,.......
Anyway, use something like Hi-Tack on the little (thin) gaskets? (Oil filter housing, seal carriers, and the like.)
Some RTV on the oil pan gasket?
Copper for the head gasket?
Dave, Tyler, Dan(s), any thoughts?
tia lots!

I only ever use sealant at these places:
-front and rear main seal flange lower corners where the oil pan gasket meets
-valve cover gasket to rubber seals
-coolant flanges on heads (just a skim layer)
There's no reason to use it anywhere else especially not on the head gasket.

I hate that stuff with a passion. I have bought 2 garbage engines because of this. Basically the PO gobbed the stuff on a coolant flange and some got into the coolant system. A big chunk broke off and got stuck on one of the headgasket passages. That part of the head overheated and warped. Twice! :evil:
But that is user error. If you use it go easy. I only use it on the oil dipstick when it leaks (at the base where it meets the block)

Tyler, speaking of wich, (Oil dipstick tube), how does one remove it from block and then transplant it to new block? Without ..........umm.............
messing it up?

While you don't specify which engine
type you have, if it's for the 1.6l,
the following is relevant:
Unbolt the bracket, at the top of the
dipstick tube, and pull it out of the
block. It's only pressed in.
You should find a washer and an o-ring
on the tube.
To re-install it, you'll need a new
washer, Part#076115643
and a new o-ring, Part #N90032203
Then, you simply press the tube into
the block, by hand.
Perhaps, as mentioned, a dab of RTV,
might give you some peace of mind.
Hope this helps

I've had ones where someone previously removed the pan and bent it out of shape making it impossible to remove without removing the pan. For example the 1.6NA in my brothers go cart. He can lift the whole engine from the dipstick :roll:

Okay, because I like it when folks do this.........
THANK YOU ALL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
I guess that can of HighTack will not get used.
Have not had a chance to get to the drip stick tube yet, pull it out by hand, eh? Have allready messed up two at P-N-P with water pump pliers, do they make dip stick tube pliers?
Once again, thanks !, and I'll post the "tubestory" as it were.

Actually, now that you mention it, I have one that's bent,
albeit it still came out of the block.
I don't think some clod took the oil pan off and deliberately
bent it, though. The curvature, towards the driver's side, looks too
smooth.
I thought, at the time, that perhaps it was intended to reduce
the posibility of oil flowing UP the tube (or something).

I put a bunch of small o-rings on my dipstick as I was afraid of water ingress should I be crossing something a little deeper than I thought it was. Even with the extreme blowby I had, nothing came out my dipstick.

since the 1.9's have that vent for the oil pan, any pressures down there should be vented back into the intake through the breather. my 1.6 however does not have this, and my dipstick is always sticking an inch out... unless i drive very soft. :roll: i'm worried about debris falling in there, but it is a pretty small creviss.

Mk1 diesels also have that piece stock as it was needed to lubricate the vacuum pump (I think). I know they have that piece I just am not 100% sure that that is why it's there.

I think that it (flange with hose connection) is the output of the diaphram type vacume pump, the vane type does not have the hose connection on that flange.
Otay, maybe HighTack on the paper gaskets and a little Ultra Blue or Grey
on the thicker ones for water and oil control.
Once again, thanks one and all for the replies!
