Tube found in intake port of cylinder head - lpr1981 - 07-04-2015
OK, this was a bit of a 'what is that doing there' moment with certain words replaced with others!!
A piece of aluminium tube sat in the intake port of piston 1, I assume this could of come from somewhere in the induction system.
Any ideas? I am yet to investigate properly but the tube is very rough in touch so I guess it's been jumping around in their for a while.

Looks like cast alloy, weird...

What the hell
RE: Tube found in intake port of cylinder head - Niall - 07-04-2015
Well thats a new one! It doesn't look like anything i recognise from belonging in the inlet tract of a peugeot engine!

Lolwut?

Urm okay then..
RE: Tube found in intake port of cylinder head - lpr1981 - 08-04-2015
It is very random, I had a dig around last night and could not find any sleeves missing from any thing. I just don't get how it got to that location, even if it got past the air filter it would have to negotiate a lot of butterfly valves and bends.
From what I can see it has not damaged anything apart from itself.

"mate I've heard if you put a tube in your inlet it speeds up the air flow for more powaaa!"
RE: Tube found in intake port of cylinder head - Toms306 - 08-04-2015
Isn't that a spacer for either the PAS pump or AC pump? Sure I've got some of them in my 'random bolts and shit' box...
As for how it got in there though, dropped while the inlet mani was off previously I reckon, can't see it getting past the TB. Though you'd think it'd be noticed while refitting lol.

Subsequently all of the aluminum flakes/particles have gone straight through the rest of your engine, possibly now ended up in the oil system too. Like pouring some sand in your inlet

Very true

Did you see the air filter on my other post?

I think a little aluminium is the least of my worries, I am waiting to find a random animal wedged somewhere :-)
RE: Tube found in intake port of cylinder head - lpr1981 - 09-04-2015
I finished removing the cylinder head yesterday evening, instead of removing the exhaust manifold I disconnected the downpipe (saves standing on my head in an engine bay). When I lifted the head off load of water poured out of the manifold!
The head bolts were not really that tight, I would say the same as a wheel nut! But the head gasket is really degraded so I guess I could put it down to this.
Guess which cylinder had the leak to the water jacket?

Jees that looks rotten. When my Rallye HG went from overheating it looked pretty normal on removal.

I think that would be a complement to them
RE: Tube found in intake port of cylinder head - Ruan - 15-04-2015
Looks like someone has changed the gasket in the past and put on a motorfactor fibre gasket... They're total trash!
No wonder it failed.
RE: Tube found in intake port of cylinder head - welshpug - 15-04-2015
nope, stock s16 was a fibre gasket, doing well to last 23 years! the only XU engine that used MLS as standard was the RFS, even the 405 T16 had a Fibre gasket.

Explains why I can only find a fibre gasket.
RE: Tube found in intake port of cylinder head - welshpug - 15-04-2015
you can use the MLS gasket if you want, no clearance issues on this engine like the RFS with its tiiiny valve cutouts.
RE: Tube found in intake port of cylinder head - Ruan - 19-04-2015
Ah sorry, forgot it was an XU10J4 - not an RS.
RE: Tube found in intake port of cylinder head - puglove - 19-04-2015
Strangly i found somthing VERY simular in port 2 in my 1st gti6 !!
RE: Tube found in intake port of cylinder head - ginge191 - 19-04-2015
Interesting.

Looking inside, the plenum chamber itself has nothing which resembles that, i'd be surprised if something that large could navigate the throttle body... no idea where that could've come from
RE: Tube found in intake port of cylinder head - welshpug - 19-04-2015
wrong inlet manifold...
