Planning to upgrade to a CDA mate to be honest - when finances allow.....
Which will be the 10th of never at this rate....

Yep, a possibility.... The annoying thing being it's very hard to say!the valve could have been damaged from the initial failing of the conrod, then when they done the rebuild put the valve in a different position in the head so not on the same cylinder.
Agreed, but I can't see any other cause for it to be honest. If it was a hydraulic issue I would of thought it would of affected more than just that one valve. It's deffo not timing. It must just of been a weak valve, what other explanation is there?
I've got spares mate, but thanks anyway
well when i went down the "performance filter" route on my golf i got a pipercross, reason being that its job primarily is to filter. i know a few motorcross types and the only use foam filters because they keep the crud out the best.
People fitting 20v valves need to take heed of this:

when you say that the agu has large port, do you mean it uses bigger valves?
how come you did'nt just use the AGU engine with the forged rods?? id definantly have used the larger port head if i were in need of replacing the engine also why use the APY pistons over the AGU's when your using the AGU block??? be quite a good setup with jbs mani hybrid turbo and a nice little map from bill
just thought what inlet mani will you use then as AGU will use the opersite side intake?? and the APY will be small port so will be no good surely?
....I wonder if the phantom misfire will return once you get the new engine up and running!...
...if it does it may be followed by a phantom 'fire'... ;P
I hope AM provide a quality metal head gasket for you
btw - badgerwagens running again

No, the ports are larger
hahahaha. Sorry, that sounded rude!
The AGU had larger ports in the head. Later engines had smaller ports, which increases speed of flow, apparently helping low down torque, although ultimately, an AGU can flow better at the top end.
Yeah, the inlet ports are about half an inch width wise bigger. The difference is massive. I will take a photo of the two next to each other before tomorrow's refit so you can see.... The difference is huge!
just thought of a question for bill
would the large port head be a better option for a k04 hybrid setup due to the torque being raised up the rev band thus giving less torque spikes or are these differences in large and small port not going to make that much a difference in the real world,
looks like your setup could be an awsome hybrid turbo set up if my theroy is correct especially with the forged rods
if its gone badly hell be stood out the front of his gaff pounding the life out of that engine block with a sledge hammer
largeport head will eat the volume any k04 can produce, hybrid or not.. so I would expect less torque spike but probable lower rpm where its falls off boost as sustained flow will not be possible.. the choke point of the k04 hotside however and exhaust manifold remains tho, so although the head can flow more the overall system is still held back.. will be interesting to see logs once its back together and see how boost abd airflow hold up

I would of thought that the N75 duty cycle will take a big change from before from where the management is trying to produce the requested boost against that head....? Turbo will be balls out all the time!
I was sat in the corner crying and rocking whilst..... I didn't even have the strength....
Last night was NOT a good night at all.
First, the head gasket got put on upside down by someone who I asked to put the HG on.... Whoops. Bolted the head down and timed up. Filled with coolant. Leaks like a bitch. Realise what's happened. Unbolt head. Replace (now absolutely shafted - bin bound) gasket - correct way up.
Bolt all back down again & time back up. Fortunately we didn't pull the pin on the tensioner (more on this later).... Bolt the coolant pipe to the side of the head. Fill with coolant. Leaks like mad from the pipe on the side of the head. Take pipe off, inside all cracked. Find the on off the other engine - not exactly the same, but close enough. No O ring for it though. Fill O ring hole with instant and bolt on (hope for the best!!) and reconnect pipes....
At this point decide it is time to pull pin out of the tensioner to finish the timing belt. Pin snaps leaving tensioner locked down in position. No room to do ANYTHING about it obviously as the engine mount is in the way.
So at this point, I decided to pack it in. Fitted 2 heads last night basically and was cream crackered!!
I've got some good photos of the AGU/APY port comparison though which I will post tonight (forgot my camera this morning).
So, all of that combined with tools seemingly growing little tool legs and running off, made me unhappy.... I must of spent an hour looking for things last night (and that REALLY bugs me!)
Head Gasket upside down??? c'mon......... which muppet did that?
A mate of mine you haven't met. And you won't now since he is now dead.
tell me about it, when I changed my steering rack, whilst the subframe was off, i came over to the car to find my mate aimlessly spinning the steering wheel over and over again, asking ''how many times will this spin before it stops?''
Clock spring obviously broke. *******.
ready for the 3071R Bill is going to order for you
Welly, I really hope you get this sorted soon! After all you've been through with it you deserve for it all to come together nicely and never to have another problem with it!
