So if the cam marks are where they should be, The belt hasn't jumped a tooth and if the timing light is showing the right angle then this would rule out the cam? Or would i still need to replace the cam for one with a key and the CAS for one with a key?
I suggested that the timing light was showing the WRONG angle. Check it - it should be 15BTDC at idle.

Forget about the cam / CAS - just get the ignition timing right. (you don't need to replace the cam or the CAS)

Well they have done a compression test and said that the compression was pretty low on each cylinder. But they were all the same. They told me that they have been busy the past few days and that tomorrow they will be able to put in a propper look.

Maybe you've done a head gasket or got a split in the plenum? seems odd that it was fine 1st thing then not a bit later. I can't wait to hear what the problem was, no doubt it will be nothing we have suggested here lol

Well friday morning the solinoid that adjust's the valve timing was working fine. Then later in the day it stoped working. The ECU was not sending the turn on command. Then this morning 1st thing it was working fine again. It was even sending the command this morning when it wasn't connected to the solinoid. Which rules out the solinoid as being faulty. The few things we noticed was there was a colent temp sensor error. and the O2 signal was at 0Volts. So were changing the O2 sensor and the colent sensor. Then were going to throw it back on the dyno and see if it's happy or not.

dude i have told you its the CAS it will cut in and out random thats why i said give it a tap on the dyno thats why it was fine for ya drive then went back to shit, also o2 sensors dont do anything except economy when ya tune a car you disable the o2 sensors so dont bother changing them and your tuning shop should know this are you sure thy know what they are doing?

I would suggest you have a broken wire somewhere in the loom to the solenoid. It is intermittently losing connection because of vibrations, then making the connection again.

Try permanently powering the solenoid - see how the car goes. Try a new connection between the ECU and the solenoid.

there was a thread on here where a guy had a misfire on his GTR.

he changed every single thing that everyone suggested.

then later, he found that the LOOM, where it goes through the panel work, had rubbed against the metal.. eventually, one wire got scratched open and would keep thouching the bodywork, causing a short out each time, which was like a missfire for the owner.

I'm sure it was near the wheel well...

might be something else you can add to your list to check.

I think he has a missfire thread here..

I know your's isn't a missfire and neither was his really...

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
