kyteler Posted May 29, 2007 Share Posted May 29, 2007 I could have it going again before then. It just depends if I can be fucked after workCould have it going by the time tonights over but can't be fucked Heads off, gasket looks fine. Valves look to be the same as the 1600 head and chambers seem to be about the same size. Will have a decent look tomorrow in the light. Fuck knows where 40psi of compression is escaping. rings boe?

CaMpylobacter Posted May 29, 2007 Share Posted May 29, 2007 sometimes they don't smoke just down on one pot? Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted May 29, 2007 Share Posted May 29, 2007 ^^ realise that, but just trying to figure out signs to what it could be. 1 @ 140 1 @ 150 2 @ 90-110 Quote Link to comment Share on other sites More sharing options...
CaMpylobacter Posted May 29, 2007 Share Posted May 29, 2007 My guess is the head gasket leaking between those two pots. or something. Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted May 29, 2007 Share Posted May 29, 2007 Will just have to put other head on with new gasket and find out, will find a straight edge and check out the current head. No water in oil or anything like that. Hopefully you're right Quote Link to comment Share on other sites More sharing options...

zep Posted May 29, 2007 Share Posted May 29, 2007 note on heads, it was the really early g161z ones which were better. well in aussie at least as they were preEPA for them. its possible that all our isuzu gems have big valve heads and the holdens have small. depends on what they had in japan.

cute wee gem Posted May 29, 2007 Share Posted May 29, 2007 Ah sweet, thanks zep. I read that cast numbers 7, 14 and 21 were the good ones and the spare is 21 Quote Link to comment Share on other sites More sharing options...
CUL8R Posted May 29, 2007 Share Posted May 29, 2007 Yea , theres a big difference in the Early model power outputs vs the later model, the later models were choked down with emmisions crap, greatly dropping outputs. Cheers,Chris CODE = G161Z COMPRESSION RATIO - TX/TC/TD = 8.7:1 COMPRESSION RATIO - TE/TF/TG = 8.3:1 POWER = TX Pre ADR27A = 63kw / TX Post ADR27A = 61kw / TC&TD = 61kw / TE-TG = 50kw Quote Link to comment Share on other sites More sharing options...

thminiman Posted June 3, 2007 Author Share Posted June 3, 2007 mean, shoulda weighed it before/after taking meat off. was keen to see how much gman had taken off mine, would be getting up there i reckon eh, half a kg or some shit you've got vizard book aye boe, fucking just take to the head like he says, that sorta shit looks prettty standard for most heads, so much shit you dont need etc should see mini's head, fucking nuthing is the same, except for the casting shit on the outside Quote Link to comment Share on other sites More sharing options...
avenger79 Posted June 8, 2007 Share Posted June 8, 2007 Whoa, i fully havn't posted in here yet I can't decide on a colour to be honest. I love the colour on Zane's Avenger Thanks boe, I <3 that colour too. About a weeks worth of farting around with colours. Quality brand of paint helps too However I'd love to see this thing gloss black, with a slight pearl. I might have a play with shades at work monday if it's quiet. A slight dash of silver would look nice too, it highlights angles and contours. Also, Have you considered a full Chevette conversion?? Motor,body,chassis,trim,interior......Everything. Even the tourists are doing it Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted June 9, 2007 Share Posted June 9, 2007 Not really Probably going to keep the trim fairly original now I've decided. Its grown on me For those who've played with the G series engine.. anyone had problems with the timing cover not coming off. (engine still in car) I think I may have to rip it out and drop the sump etc Really want to be able to drive her to the nats.. Quote Link to comment Share on other sites More sharing options...
mikuni Posted June 9, 2007 Share Posted June 9, 2007 PM zep about g series shit. He's been playing with them the most, otherwise ask questions on http://www.ozgemini.com , they are pretty helpfull there and know their gems, even if they can't do them up right Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted June 10, 2007 Share Posted June 10, 2007 Engine is out and head is back on for good, had to drop the sump to get timing cover off. The reason I couldn't get the head back on the first time was because the tensioner release mechanism was bung and didn't work so I wouldn't have been able to fix it without the engine out anyway All fixed though, I'm just hoping for the best with the new head. All I need is to make it to taupo and back for nats Quote Link to comment Share on other sites More sharing options...
