My lifter valves are extra stuck in the underside of the bucket, the banging method definitely doesn't work, so I've tried pulling out with lockjaw plyers, but that seems to damage the black collar which holds the valve assembly in the lifter. Do I pull on the black colar, or pull on the stainless valve assembly? (which contacts/opens the inlet/exhaust valve) is there a method or a tool that doesn't smash up the lifters too much?

Cheers

Generally speaking if you're marring up a machined surface you're probably doing it wrong. Is it possible to use a small punch, rubber hammer, and a socket to tap it out?

Yes my thoughts exactly, I did see a tech on YouTube doing what you are saying, but I can't seem to find a punch small enough to fit in the top hole.. Don't want to in large it any bigger.

PS: if anyone got a couple spare lifters in NZ please let me know. 

Cheers

I have a punch set with some absolutely tiny punches, any chance you could order smaller ones? I'm not at all handy with machining though so my first reaction to most problems like this is to throw money at it.

I tried to modify my punch this morning but can't get it small enough without it degrading the structural integrity of the tool, so I'll have another look around the big smoke on Friday (couldn't find one fine enough last visit) when I'm in town, got to love rual living haha

Perhaps, if you have to have another shot at this, try using a file. Punch lays flat on a steel workbench/piece of flat bar & held there. File kept as parallel to the surface as possible and pushed across the punch. Rotate the punch a little after every stroke. Will be slow, but will eventually get there and is not quite as violent as trying to lay a really thin punch remnant up against the grinder.

Or, do what you can with the grinder, then when you get down to the limit of comfort, change over to the file.

If ever you don't get around to getting these to work, part# VL4951-P24 for a jobber set of these lifters that can still be purchased. I bought a set for 200-300$ from Tog in Australia roughly a year ago. My engine machinist is the one who recommended them. 

Cheers.

    • One other question, is there a chance that changing the idle speed can lead you down a rabbit hole and is the reason the tuner didn't touch it? Reason I ask is because if that's the reason the tuner avoided it then I probably shouldn't be touching it lol.
    • Pfft. As if I'd ever point a high pressure washer at my car.
    • The nature of my commute has changed. Way back then it was traffic lights all the way, for ~28km. It sucked. When they finally stitched the expressway together I could do a good 15+km of it at a steady 80-100 with no stopping. That alone has gotten me down to flat 10s. Prior to that it was mid-high 10s. I can't remember the delta that I saw when I got the idle down. It was only ~150 rpm, because the idle speed was never terrible, but for the delta in consumption to be noticeable it would have had to have been at least 0.2-0.3 L/100km - which is not to be sneezed at when it comes for absolute free. It's only about 50L per year, but that's ~$100. A few extra pizzas is always welcome. Note that I have a record of every tank of fuel that has ever gone through my car except for a handful put in by someone else, like my mechanic. I can show you the difference between stock RB20 and tuned RB20, stock RB5Neo and tuned, winter and summer fuel blends, winter and summer fuel blends when the ambient temperature is not appropriate for the blend, working O2 sensor, blown O2 sensor, boosting f**k out of it and frightened to boost it because it is pinging, and so on. OK, I probably can't do all that now with 100% clarity - but at the time when any of those things were in event, you could see it in the records. There's 25+ years of simple tank after tank records, so you have to look for landmarks to work out approximately how old any single record is. What's really important is the meta data and that lives in my head.
    • If you're claiming the issues are not skyline specific, then either the USA is living in the 90s / early 2000s, OR you have the issue of "survivor bias". Which is you're mainly hearing and listening to those with terrible experiences, and haven't found the guys who have cars with good decent builds and no problems. It happens in AU too, that plenty of people keep having issues, and they keep going to the workshops that are known to be shit "because I read on the internet". Even worse, are those who keep posting on the internet as though they know for a fact what something is, when they've never touched/looked at said item in their life, and again are making assumptions, based on something they read, or because it's a certain way in other cars. It's even funnier when those same people debate the facts with the people who've lived and breathed this stuff for over 15 years. Example, I've had someone tell me you can't do something with a Skyline, because they read it on the internet, except I can tell they're wrong, as I did that exact thing back in 2008 with my Skyline.
    • The funniest part I saw, was someone would bitch and moan on FB about something, Andy would be the one to respond, asking for more info, if he could contact them, what the engine setup is, what their config file was, and 95% of the responses were people just going "der! It doesn't work" and Andy going "What doesn't work?" And then going "The firmware!" And they'd go around in circles as no one could ever give information, and Haltech couldn't fault things on the bench, (especially when people wouldn't give any specifics).   Many moons ago, when Andy was back at e420c stage, he reached out to me, and asked me to test different plug and play looms for him (already had an e420c in the car on his V1 PNP loom). And he kept asking me, as I was competent enough to be able to give him some specific feedback on what was/wasn't working, how to replicate the faults etc, and work through things with him. Most people are terrible at answering the questions they're asked, or being able to provide quality feedback other than "it doesn't work".
