Re: My Head is all Scratchy (Pg. 111) - The Speedfoos' Turbo Thread!!
LOL - wtf are you talking about? I'm a growing boy, needs to eat.
Actually about the only time I ever sit down is when I'm eating or what I'm going to eat is cooking so there you go. Most of the time I'm busy doing something. It's one of the benefits of not having broadcast TV - unless I'm playing a game, or watching a movie at night, I don't watch any TV.
Jay, you want to be between 11.5 - 12.0 under WOT and full boost. 11.5 gives you a margin of safety to avoid detonation. That being said, my AFRs are kind of all over the map right now because of my leaky head gasket, ranging from 10.8 - 11.8 (ish) under boost. It's safe, just not optimal. I'll fix it this weekend after the new head goes on.

That looks pretty good for a first time Ching! I will probably try my hand at my current head (the one that is sitting on the car for about 4 more hours) to see how it comes out. Once you smooth out those transitions and polish her a little bit it will be nice.
Going out to the garage in about 20 minutes. It's cold!

Good god that loks like a lot of work haha. Good luck man, look forward to seeing the results from that new head. So were the two middle cylinders where the HG was leaking or the two outer, because they look distinctly different (or was that the flash of the camera)?

^^^ Absolutely Dopes.
Cyls 2 and 3 were the ones with low compression, but those pics were after sopping up oil and coolant and scrubbing the old gasket off. And plus there are at the bottom of the stroke whereas 1 and 4 are up top.
And no, the work never really does end!

your oil pan is on the way clint.
anyways, i really hope youre straight edging that block before you drop the head back on. you can spray as much copper **** on the gasket as you want, but if the deck and the head arent flat, it aint gonna seal. I wouldnt use the copper **** on a metal gasket IMO. it's already got that coating on it from the factory. what are you torqueing the studs to? and are you using moly lube to get the preload right? last time i did my oil change, i spotted some nasty watery oil mix on the cap, but the oil came out looking ok, and the coolant level has been the same since the motor went in, but the stuff in the catch can looked like watered down gravy. i need to re-think my breather setup because i think thats where the moisture might be coming in from.
grammar > me

LOL - send me you damn PayPal addy and the shipping cost already man!
OK, I straight edged the tops of the bores last night and everything was good. I'll do the block today and see what happens. The head I'm putting on there is flat - or so the machine shop told me, I'll have to believe them.
Studs are torqued to 60 ft./lbs as per ARP's recommendation. I did use the moly lube they came with when I installed them. I shouldn't have to re-seat them should I? None of them came out during when I loosened the nuts.
You're probably right about the moisture being breather-related. I'll be completely re-doing my setup with some check-valves and plumbing it into both the IM and the exhaust to get all that **** out of the engine.

dude clint, ur ****in crazy, i hope all goes well, good news about ur cylinders too, im curious to see how this all turns out, its looking pretty crazy, i hope when ur all done u turn the boost way up and go at it(with a video camera on board of course), u are torquing the head studs right... im sure u are, just make sure u r doing it in the correct order, what is the correct torque anyway?

Yeah, the head's still off, let me go outside and snap a pic real quick.
Adam, the correct torque on head bolts is like 48 ft./lbs IIRC and on the the ARP studs it's either 60 or 65, I'll check before I spin them back on. In regards to turning up the boost, I should be able to make more power at less pressure, so - if things go well - 6 psi with the new head will feel like 9 psi on the old head.
Everything is just about ready to go back on the car. I still need to do the valve lash, but I finished prepping everything else. Let me go get those pics Ching.

I should be able to have it running tomorrow. As soon as I find my Hayne's manual for the valve lash specs and torque settings for the rocker arm assembly, I'll do the lash. I think it's in the car.
Yeah, I'm going to have to re-tune. I'll get it close by myself, and for the rest of it, well that's what I paid Chris for. One year's worth of tunes - good until Sep 08.

I've got about 39K (miles) on this block Ching. Those two cylinders are also the ones that showed the major compression loss too.
Valve adjustment is done!

LOL - yeah, but the valve lash specs weren't in there. Even in the section of the book where it outlines the procedures it says, "refer to the beginning of this chapter for the valve specifications". But they weren't there. Search button and Gray's Valve Lash Adjustment DIY FTW!!
So how do like the turbo now Tony?
