ok heres the latest update... Replaced the timing belt correctly and started and ran fine but still smoked. Replaced PCV filter and used motor flush additive in oil and changed the oil. Then heres the confusing part... re-did the compression test an got some different results... Dry Wet Cyl1 - 180 - Cyl2 - 80 120 Cyl3 - 180 - Cyl4 - 45 65 This now would lead me to look at the rings as the problem... but is it weird to have two go in such a short period of time?? am i even on the right track?? Thanks again for all the help guys. Matt

that sounds like a pretty good idea actually an it definately couldnt do any harm i guess!! dunno why i didnt think to do that before pulling it apart! thanks again for all your help its awesome!

sorry jerry its N/A forgot to mention that at the start... thanks though!!!

yeh put the belt back on properly and put it all back together and still smokin!! gonna test compression again tomorrow i think. i really wished it was just that timing issue!! ah well... any other ideas??

hahaha dont i feel stupid... yet again you guys were right!!! i went by the arrow on the crank sprocket and only realised when i had it all back on there was a mark on the back which i was meant to be using!!! at least that is easy fixed!!! anyway assuming that she fires up again after that... what would be my next step? could the incorrect timing be the cause of the smoking or just partially to blame? do i put it all back together and re-compression test? or just cut my losses while ive already got some stuff off and move straight on to splitting the block assuming its valves? thanks guys

good point about the cam sprockets now i think of it there should only be one spot they can fit on like you say. just doesnt make sense to me!! yeh i found heaps of threads on here and used the endwrench article was sorta confusing but did help. Ive only ever done one t-belt before an that was on a EA82 which was a little different!! but this was pretty straightforward. did like you said anyway and lined everything up but it didnt start or even come close by the sound of it. usually starts first kick. so im gonna put the belt back on the way it was i think.

ok so that didnt work... now i assume that the cam sprockets were put on incorrectly and go back to the positions they were in (lucky i marked them!!) except the left cam needs to be advanced one tooth... see how that goes.

so i should go by the cam positions rather than the crank? think i might try line it all up to the marks and see what happens haha

that definately seems like a good idea and a much easier thing to check than valve seals!! so i have just pulled off the t-belt covers and all the other stuff in the way to have a look at the belt and something is troubling me... when i first was rotating the crank by hand using the accessory pulley i obviously couldnt see the timing mark on the front of the crank pulley so i used the right side cam pulley marks to line it up. With the right side lined up (cyl1&3) i then checked the left side (cyl2&4) and sure enough it appeared to be off by a tooth or two. However when i removed the accessory pulley off the crank to check the crank mark it showed the mark was way off (at about 4-5pm instead of 12 where it should be) I then checked the valve position with the crank pulley marks lined up by removing the rocker cover and the valves appeared to be in the right position (all closed yeh?) i also assumed that if the cams were as far off as they appeared to be by the marks earlier then the car wouldnt have run which it has been earlier... So my thoughts are that the cam sprokets have been put back on in the wrong position at the last timing belt change... would this be right?? Should i put everything back on as it was or try line up all the marks and see what happens? non interference so couldnt hurt i guess? thanks guys!

that would make sense actually and i really do hope your right!! i re-did the compression test as i forgot to warm the engine up the first time and heres what i came up with... Dry Wet Cyl 1 - 180 - Cyl 2 - 110 110 Cyl 3 - 187 - Cyl 4 - 70 72 this would seem to show that it is the valves to blame rather than damage to the rings or cylinder walls? or as john said because both the cylinders came up low on the same side could it be a timing thing? any help would be appreciated!! thanks guys

ok so i did the compression test with the following results... Cyl1 - 180psi Cyl2 - 95psi Cyl3 - 185psi Cyl4 - 60psi Uh oh!! Those numbers were dry test. about to go back out now and check 2&4 again wet to determine if its valves or rings to blame... ill post again when ive done that.

yeh thats a good idea thanks jerry. Looks like a pretty simple test to do and should give me a good indication of the condition inside without having to pull it all apart! thanks for your suggestion ill post back the results when i do the test just to check im doing it right!! thanks guys

haha g'day mate, thanks for the reply. Sounds like i found the PCV alright. after i had cleaned it could see the valve move up an down and hear it rattling but as you say may as well try a new one. cleaned up the rubber tube also had a fair bit of build-up in there too. thanks for your help!!

so upon further inspection of the car and looking around the forum i have come up with two possible answers... There is a large buildup of oil in the box between the airfilter and the throttle body (over 100ml) which appears to be coming from the breather pipes on the rocker covers... took pipes off and ran engine and a fair bit of smoke and some oil came out of the breather pipes. Cleaned out the PCV valve (at least what im pretty sure is the PCV valve!) which had a fair bit of junk built up in it and probably couldnt close. Still getting CEL codes 24 & 35. From searching the forum i am guessing its either a damaged piston ring or the valve stem seals? but i am fairly new to all this and so would love some help!! Thanks again for everyones time

hey guys im new with all this but bear with me... I need help!! Ive got a 91 liberty wagon AWD EJ22 5sp Man which is giving me problems!! firstly, the gearbox has 'done a bearing' (what i was told by the mate i bought the car from) and after driving around with a grinding gearbox for a few months fourth gear stopped working alltogether. This wasnt the major problem though. After driving around with no fourth gear for a while something has happened in the engine. Big clouds of smoke are coming out the exhaust when it is first started then periodically when driving and there is also a sort of lag or lack of power lower down in the rpm. Checked the CEL codes and its showing: Code 24 - Air control valve Code 35 - Canister purge solenoid Also when looking around i pulled out the dipstick to check the oil while the engine was running and smoke comes out the dipstick tube. I also noticed (not sure if this is relevant) when i pulled off the hoses between the airfilter and throttle body to have a look around, that there is a lot of oil in the actual hoses. Sorry bout the long post but i need some help as to whats gone wrong and what to do about it!! thanks heaps
