140 DSG - Porous Cylinder Head

davidcollins01 · 29-03-2007, 16:11

Well, after 4 trips to the dealer to find out why my car seemed to be drinking coolant, its been discovered that the cylinder head has become porous. They've told me that its been leaking oil and coolant because of this.

I was wondering if anyone else has had the same problem?

porous indeed!!!

more liekely the head gasket wasn't fitted properly at the factory..... tell em you want a brand new engine

Tom_vRS · 29-03-2007, 16:19

Porous? Eh, its made of alluminium!!!

TeflonTom · 29-03-2007, 16:31

it's not pure aluminum mind you.... it's an alloy made from aluminium, magnezium and silicon, they are normally pretty good too, iirc they are made in the vw foundry in poland....

davidcollins01 · 29-03-2007, 16:32

They've ordered me a new one. I reckon by porous they meant gaping hole

New engine will be the next port of call if this doesnt fix it. One of the diagnostics they did was to put UV dye in the coolant and its shown up somewhere or other.

Car currently in bits in the garage. At least they have an account with Europcar and are getting a car to me before 5:50 (at work too)

TeflonTom · 29-03-2007, 16:35

glad they are treating you well.... and a courtesy car too

davidcollins01 · 29-03-2007, 16:48

They are being really good. I've already had 2 phone calls from the technician working on my car asking bits and bobs.

It is a golf, but i always expect VW dealers to be a little less courteous and helpful than Skoda ones.

Done plenty of pourus heads on the 2.0 PD in Golfs and Tourans. They leak usually from the water way in the head into the inlet port on cylinder 1.

Not seen one on a Skoda though but have heard of the EGR cooler leaking into the engine on the Octavia.

The 2.0 gets worse and worse

How do the problems on the 2.0 compare to those on the 1.9 when it was introduced?

Lummox · 29-03-2007, 19:43

its not getting worse, these problems have been resolved and are on older cars. Most of them before Skoda got the 2.0.

I saw a porous head on a Felicia, as the engine was running you could see the coolant coming out of the top of the head.

I heard about a Dodge Viper that wouldn't start or run right at its' import centre. They spent something like 160 hours on it and eventually by swapping parts from one car to another they found that the plenum chamber was at fault, that turned out to be porous.

The C20XE Vauxhall engine was renowned for pourus cylinder heads, as is the K series from Rover (which also just corrodes away and warps).

davidcollins01 · 30-03-2007, 13:15

Lummox - Is this something that they have fixed in the replacement heads?

Yes mate, modified design. Not had a repeat failure.

Looking at VAG wide not Skoda specific here..

Head gasket issues (early Audi engines iirc)
Pourus cylinder heads (sorted now)
Turbo failure
Throttle body seizing (also blows cooling fan fuse)
Oil pump drive failing (no oil pressure)
EGR cooler leaks into engine
Glow plugs burn out dropping the end into the cylinder

Just a few ive done. More on VW though if i'm honest, Skoda seem to have done well as most of these issues have been addressed prior to Skoda getting the engine.

Nice to see that VW and Audi owners getting their money's worth out of the price premium. What a privilege to be a beta-tester!

Lummox · 31-03-2007, 17:05

Yeah but Skoda had the Fabia first..lol. No PAS sensor faults for the likes of VW and SEAT..lol

davidcollins01 · 02-04-2007, 21:40

Glad to hear a redesign has fixed it

. Should have the car back tomorrow w00t!!!

Vauxhall 2 litre 16v heads go porous, they're aluminium...

The old Triumph Acclaim used to suffer a porous engine block issue, they too were Aluminium.....
