seat/vw-audi engine damage anyone seen this before?
 

just changed the exhaust valves on a seat cupra 20v turbo as the belt had broken. striped the head off and fitted 8 new genuine seat ex valves, depressurised the lifters and reassembled it back together with new belt,tensioner and idler pulley etc.

started the car and it ran fine for 10 mins and then it made awful noises and stopped. checked the belt timing, no problem there. eventually i took the cams out and found that the top of one of the new exhaust valves had broken off allowing the valve to drop into the engine :( . i have never seen anything like this before, anyone ever had this happen?

seat have a big warranty claim on their hands!

Holy fook, ive seen that happen on a merc engine when i was an apprentice :top:

go for the throat Martin!

as discussed on the phone martin , any probs give me a ring during the day , i will make a few enquiries anyway to test the water ! ;)

we had a simular problem on a passat belt broke took head off change valves car ran fine then the same thing happened to the passat dropped a valve
had to take head off again and do job twice bummer
to be honest thought it was down to us
after refitting the head second time the car went out and no come back
thanks jc

never seen this the only thing ive every seen is the tappets loose pressure through wrong oil and u get no compression but never a snapped valve

cheers jay

cheers mark :top:

he nearly did, mine, :eek: :eek: untill he found it had clearly broken

Fookin 'ell :eek:

That's more than a touch concerning

ROFL - that must have been a bit of a "moment" :eek: ;)

Not the same I know but had a CRX V-Tec come in once that had dropped a valve, bounced around the cylinder and parts had gone back up the inlet track and into the cylinder next to it........ made a right fookin mess

i've seen that before .. it happens because the spring isnt seated propperly in the head.... quite a common fault when rebuilding theese.

:eek: :eek: :eek:
I read of a similar story on the VW forum last year.

I can just see martin chasing you round the seat "come her you useless git"...... " but but it wasn't my fault"...... :cry:
lol
