Oh cock! Melted a plug!
« on: December 29, 2008, 03:22:43 pm »
Went Eurocarparts to get a new ABS sensor for the Golf Anni and decided to take the G as it was nice and cold so the old charger would love it.

Blasted down the dual carrageway (me and yoof's test road) full pelt and the engine spluttered at 6000rpm suddenly.

Pulled over and the car was running REALLY REALLY rough. Waited for the AA man as i had no tools and removed Cylinder 1 plug and here it is!!!



Its a proper Bosch W5DP0 as well, only done like 200miles!

Replaced the plug and it still running uber rough so the head is coming off as i reckon the valve will be bent if the end of the plug has gone through it!

The head was coming off anyway for the 1341 high lift cam but i wasn't expecting to replace the valve or the head if its proper fucked!

COCK!!!!!

hmm well I've got the head off my g40 but the waterways are a bit corroded.  It never leaked but it's less than ideal.  To be honest mate you'd be as well just getting a cheapo 1.3 CL head and swapping the cam and exhaust valves into that and refreshing it a bit.  I'd get your head off first before you start worrying too much about finding a new one.

Right the head is off! busy couple of hours thats for sure!

Exhaust Valve on Cylinder one is mullered, the seat is shagged as well.

It looks like the plug tip got mashed in between the valve and the seat.

I am guessing seats aren't replaceable and if they were i think it might be best to get a replacement head as the valve guide might have been damaged as well.

Ah well at least the pistons look good and there is no signs of det which is even better!

On the plus side i was going to have to take the head off anyway to fit a new cam and also new cambelt etc and to inspect the pistons. Just need a new head now!

Oh piccies

bloody hell!  yeah that's going to be a new head required.  Just get any old 1.3 CL head, if you need a proper g40 exhaust valve I have a set of four I'm not using.

That head may not be scrap if you get bigger exhaust valves, which will have new valve seats fitted. Best to take that head and get it looked over by a cylinder head specialist. They can do all sorts of repairs!

Get yourself the set of exhaust valves from Mr Hayes and a 1.3 CL head from the scrappers and your onto a cheap enough fix, as long as you want to do all the labour 8)

It's a shame there isn't any kind of warranty etc involved with this kind of thing, although you were going to do it anyway you shouldn't have been forced to do it because of faulty brand new parts.

If this had happened to me i'd be shagged, i've got enough knowledge to do bits n bats with the car, i wouldn't be able to strip down a head though...this would cost a lot of scrilla £££!

good luck with it!

The engine is in bits now, i have just removed the water pump and realised that the previous owner had put the wrong pump on so the teeth don't match the teeth on the belt!!!!!!!!!

I'll be changing the cambelt and water pump now seeing as the engine is in so many bits!

Got a head sorted out for it as well which is good news, thanks Mr Hayes!

Whilst i am at it i'll put a new clutch in as well but its going to be a mission as the subframe was a right git to put on so i am hoping i can make enough room in the engine bay not to have to drop the box out the bottom of the car. What do you guys reckon? Do-able?
