wagoon 2,429 Posted February 11, 2016 I knew at that very moment and thought to myself "I really am failing at life" Nah dude you were being more environmentally responsible than the prius owner as you were trying to conserve fuel that's why the prius drove away from you. So you have the moral win over the prius owner, on top of you saving fuel they have many batteries and electrical components that were made in china then shipped to butt-fuck-nowhere to be assembled to make the pussbox that is the pruis. That requires more carbon's be pumped into the atmosphere than your 30 year old gas guzzler which is well beyond carbon neutral by now. A win is a win and it doesn't matter by how much, all that matter's is that YOU WON. 1 slydog reacted to this Share this post Link to post Share on other sites
Ando81 2,949 Posted February 11, 2016 Ha ha ok mate, I'll take that I guess. I did feel like throwing my balls out the window as he started to pull away though. 1 slydog reacted to this Share this post Link to post Share on other sites

Ando81 2,949 Posted February 22, 2016 Well I've got the fresh engine in and let's say it's not going to be left behind by and Prius shit boxes now. I've only roughly tuned it coz I only have a cheap timing light so can't tell how far advanced my timing is but it seems really happy where I've got it. Just have to get some kms on the clock and get a good tune before I give it too much of a workout. 3 Outback Jack, slydog and wagoon reacted to this Share this post Link to post Share on other sites
Ando81 2,949 Posted March 13, 2016 I'm still not too keen on this head with the repaired rocker arm thread bolt so bought a hf-6 head off eBay that has been refurbished for gas. Not really good pics but can anyone give me opinions on the looks of the chamber. Share this post Link to post Share on other sites
Lord_fahrquhar 2,580 Posted March 18, 2016 I've thought about it Dave but I'll leave it as it is now, it has to be an improvement. Worst experience today in my ute as a Prius pulled away from me going up a hill , it's definitely time for more grunt and time to get rid of the crap ring type gas mixer. If this happens again hand in your man card and buy a barina. The chamber looks open, so with a carby bottom end I suspect it's going to be low compression city. Could be wrong... 2 Ando81 and Ants reacted to this Share this post Link to post Share on other sites
Lord_fahrquhar 2,580 Posted March 18, 2016 And if it gets to the point of handing in the man card, it will be returned if a triple weber setup makes its way under the hood. Share this post Link to post Share on other sites
Ando81 2,949 Posted March 18, 2016 It's looking like I won't need to buy a Barina just yet, the new cam and 8cc dished pistons have made it a lot more responsive and it's obviously breathing a lot better coz it has got a louder exhaust note. I don't want to go lower compression so maybe the head isn't going to be much good to me. I liked it because it's been recoed for gas and I thought if it's had flow improved inside the head then it may improve torque. Share this post Link to post Share on other sites
LJDB 103 Posted March 18, 2016 It's not hard to roughly cc a head and work out the comp ratio. Also depends if it's been machined down and what head u already have. Share this post Link to post Share on other sites
winton 399 Posted March 19, 2016 Nothing wrong with helicoils. I have ripped 3 rockers out a xflow head at different times doing burnouts. Used helicoils to repair it. Never ripped out 1 repaired with a helicoil. Just helicoil it. 1 slydog reacted to this Share this post Link to post Share on other sites
Ando81 2,949 Posted March 19, 2016 I've repaired the thread with a helicoil already but as I tapped one of the threads I noticed the new thread on one of the rocker mounts was very ugly asif I hadn't used enough cutting compound on the tap. It looked like every third thread had been chewed up as I put the tap into the hole. It seems to be holding together almost 1000km since the repair but I've been paranoid of going on any long trips in case it lets go. Share this post Link to post Share on other sites
winton 399 Posted March 19, 2016 Ahh you've been thinking. The problem with thinking is it leads to over thinking,just stop thinking. 1 slydog reacted to this Share this post Link to post Share on other sites

Not really good pics but can anyone give me opinions on the looks of the chamber. FYI been prepped for gas means a standard alloy xflow cyl head. Every alloy head is ready for unleaded or gas as they come standard with hardened seats from the factory. 1 matt_lamb_160 reacted to this Share this post Link to post Share on other sites

Ando81 2,949 Posted March 20, 2016 Cheers Sly, I reckon someone had told me that a while ago. I liked it because it's had a lot of work done to improve flow, looks like the valves are standard size but all valves, springs, seats and collets look new. It's only done 2000km before the cam gear and dizzy gear got chewed up. I thought maybe a high volume oil pump and poor run in procedure might have done it.

Ando81 2,949 Posted March 21, 2017 Well fellas I was worried that this day would come. I went for a drive on the weekend and I think the head thread repair has let me down. I drove 25kms and slowed down to turn into a driveway and changed down to second gear and the old girl started to run rough and tick at idle. It's definitely running on 5 cylinders so I suspect that the thread has pulled out of the head and therefore not opening the valves on that cylinder. Will have to use the inspection camera to see if it's the problem but doesn't look like a quick fix. Might have to put that other head on after all. I got 12000km out of the helicoil repair that I did Share this post Link to post Share on other sites
gerg 10,871 Posted March 21, 2017 Could drill/tap to 7/16 and install a threaded plug with the 5/16 hole for the rocker bolt in the middle. Share this post Link to post Share on other sites
deankxf 20,292 Posted March 21, 2017 my money would be on a bent pushrod, or bolt come loose. cant see a helicoil failing Share this post Link to post Share on other sites
Ando81 2,949 Posted March 21, 2017 Thanks for the suggestions fellas, I'd gladly put another pushrod in it if it's that easy. If it's not a bent pushrod then the plug idea shouldn't be too hard to do either Share this post Link to post Share on other sites
gerg 10,871 Posted March 21, 2017 I had a rocker come loose on my brother's old XF, not long after we did a head gasket. Those bolts have a fine line between snapping off or not being tight enough. So I popped the cover, re-positioned all the bits, then snugged it down. Drove like a bought one.... until I wrote it off 2 XPT and Ando81 reacted to this Share this post Link to post Share on other sites
Ando81 2,949 Posted March 22, 2017 Ha ha. I'd be happy to see a broken bolt in there mate, or a loose one. Hoping to get to it after work tomorrow, been busy playing with my ranger that I bought as well so spare time is hard to find lately 1 Outback Jack reacted to this Share this post Link to post Share on other sites
Ando81 2,949 Posted March 30, 2017 so I found this wrong today. The stripped bolt had a straight pushrod and the bent one had a perfectly fine rocker. Anything I should check before I repair the thread for the rocker bolt? Share this post Link to post Share on other sites
