deankxf 20,266 Posted January 4, 2018 i'd assume if they are all bolted down, then you should be able to turn the motor over and those two will rock up(then be springing back) and 2 other ones will act as these 2 are now.. they are probably just in the opening stages. (the confusing stuff) firing order is 153624. that means, both valves will be closed on that firing position.. eg.. cyl 1 when on top dead center, will have both valves closed and there will be no tension on the rocker bolts, then rotated a bit more number 1 will be in exhaust stroke, so the exhaust will begin opening while cyl 5 is next for same then rotated a bit more number one will turn into intake stroke so the other will begin opening, number be on exhaust probably around this time.. you could go through and watch some youtube clips and probably find a scenario on video of this. but its probably the exact thing you are mentioning. just 2 valves fully open. 1 Outback Jack reacted to this Share this post Link to post Share on other sites

PapouGhia 33 Posted January 5, 2018 You explained that perfect and I have thought that as well, just making sure I have gone through YouTube as well and Sussed it all out, just wanted to get some feedback from people who actually worked and know the ins and outs of these motors, I’ll try and get it all back together tonight, how long should I crank the engine by hand? Will they all harden up if I do it? Cheers 1 Outback Jack reacted to this Share this post Link to post Share on other sites

Disconnect the fuel pump relay, and give the key quick flicks to wind the motor over via the starter.

gerg 10,871 Posted January 5, 2018 FYI #4 rocker is exhaust cyl 2#5 rocker is inlet cyl 3 If my brain is correct, #6 should be rocking so #1 should be TDC compression Sent from my CPH1607 using Tapatalk Share this post Link to post Share on other sites
PapouGhia 33 Posted January 5, 2018 Where abouts is the fuel pump relay? They the square fuses on the driver side? Share this post Link to post Share on other sites

They the square fuses on the driver side? near the brake booster, it's a green one, push the sides in to unclip it(it says it on it, people like Me always tried to pry the clips, but pushing them releases it easy) 2 PapouGhia and Outback Jack reacted to this Share this post Link to post Share on other sites
PapouGhia 33 Posted January 6, 2018 Cheers mate I’ll pull that out and give it a few cranks with the key and plug it back in see how is all looks, I’ll keep you updated! 2 deankxf and Outback Jack reacted to this Share this post Link to post Share on other sites

PapouGhia 33 Posted January 6, 2018 Alright have cranked engine couple times a few of them have gotten hard, should I keep cranking till they all go hard? Cheers all Share this post Link to post Share on other sites

Cheers all i think this "hardness" you are thinking of is when the valve is open depending on the position of the engine rotation when you stopped cranking.. i'd just check all the bolts are tight , pushrods are in place and fire it up personally.. that's what i've always done 1 Outback Jack reacted to this Share this post Link to post Share on other sites
PapouGhia 33 Posted January 6, 2018 Aren’t the rocker arms meant to go hard like I can’t push them down and they’ll spring back? That’s what they where like when I took rocker off the first time Share this post Link to post Share on other sites
PapouGhia 33 Posted January 6, 2018 All pushrods are down I saw movement coming from all rocker arms, haven’t seen oil coming through the push rods yet, should I go and put everything back together and start up? It’s just some of rockers are from my believes not primed yet? And are still loose not from the boot but the tension as I can still spring them down and up, hard to understand without a video.

deankxf 20,266 Posted January 6, 2018 they should self bleed if most are primed you can crank it longer on the starter if your battery is good it will prime them up fairly soon, say 30 seconds 1 Outback Jack reacted to this Share this post Link to post Share on other sites
PapouGhia 33 Posted January 6, 2018 Just put the rocker and the manifold back on, they all looked fine so hopefully when I start car it’ll build the pressure up. 2 deankxf and Outback Jack reacted to this Share this post Link to post Share on other sites
PapouGhia 33 Posted January 11, 2018 Give all. Everything is back together!!! It’s seems to be running decent but is not when’s the isc and the airflow sensor is plugged in! Is this just faulty units? Share this post Link to post Share on other sites

Is this just faulty units? that's probably a question for @Panko @Mr Polson who might have encountered this issue before.. i know the air flow meter in particular can be temperamental (temper- mental) the ISC might need cleaning with carby cleaner or similar?

Mr Polson 10,214 Posted January 11, 2018 Was it running fine with them plugged in before?And am I reading that right - it runs fine with the ISC and AFM UNPLUGGED but is running poorly with them plugged in?Sent from my Pixel using Tapatalk Share this post Link to post Share on other sites
PapouGhia 33 Posted January 12, 2018 Alright when I first got the car it would idle fine but then it started stuffing up and I unplugged the isc plug and it would idle fine once warm. Afm isn’t the problem as it’s plugged in now and it’s fine, cheers for the help guys, what oil thickness should I put in? There is still a lil ticking sound but I reckon that’s the cam. I’m looking for a isc and the hose that goes from it to manifold. Cheers all 1 Outback Jack reacted to this Share this post Link to post Share on other sites
bear351c 10,270 Posted January 12, 2018 You wont find an ISC, nobody makes them. Can pull yours to bits, and clean it, and try and put it back together, or get a second hand one. Try and find a wrecked ZL Fairlane with EFI, same engine..... 1 PapouGhia reacted to this Share this post Link to post Share on other sites

PapouGhia 33 Posted January 12, 2018 Yes that’s the one mate. That controls the idle at all temperature? So it’s basically like a choke on cold start aswell? Share this post Link to post Share on other sites
