vk problem please help
hey guys
I'm only new to this forum, and Ive been having some trouble with my 202 carby vk I'm only 17 and an mechanic for work experience
Ive been driving around my 5 speed manual vk lately, and just last night, an est light came on, and pretty much none of the lights work in my car, i woke up this morning and put the key in the ignition and it wont even turn over,
and also its just started to making a tapping noise from my engine in the morning now it does it while i'm driving and stopped at the traffic lights
could this be all gunk on the lifters?
any advice will be great
thanks daniel
could be possible its gunk, but does it sound louder the faster the engine goes? could be a sticky lifter? with the not starting problem, was the battery dead? what volt does the volt meter go to when you try and turn the car over?
yeah it gets louder as it goes faster
ok the ignition now does turn, but the motor wont start, and its a new battery
any ideas? could be the starter motor or burnt out coil?

when was the last time that you changed the oil? What colour is the oil? Not changing the oil is a good way to get sludge in the oil system due to the oil breaking down over time. An engine flush is a good way to help clear it (although many dont like using it, someone may have a better way to clear it all). This will cause the lifters to make noise which sounds like ur case.
Now, check out your battery. If it does have a good voltage in it then rule that out. A trick to see if you have power in your leads is to pull a lead out (any one that is easily reachable) and put a screw driver in the hole like a spark plug. Now place the screwdriver on the car body (like where the suspension is). With this sitting there turn the car over and see if there is a spark that arks over onto the car body. If there is, check the colour of the spark. Yellow = weak spark, you want a nice blue one. Check points and dizzy cap if spark sucks or its not there. Ive had weak spark before and a new coil fixed that right up, about $30 to get an old style oil filled one brand new which worked for my LPG 308. Leads are important too so check all leads for good spark. Ur ur starter motor turns over the motor then it works fine, thats all it does to start the combustion process. Have u changed ur air filter lately?
If u have a good spark check for fuel flow. Im not sure as to do this as i play with LPG most of the time but i'd say take a fuel line out that goes into the carb and turn over the car and see if fuel flys out. Make sure it goes into a bowl or something like a jerry can and check if there is good pressure. If not or if no fuel at all ur pump might be shagged or the lines might be block or even the filter might be blocked. If nothing there make sure ur plugs are ok, check for compression, check for air intake leaks, check to make the sure the carb is on well and that it doesnt suck air from places its not supposed to. Make sure that it is running on all pots too.
Dunno man, just try some of these. Mainly the sparking side of things and fuel. Best of luck mate! She'll get goin again soon

Paiste's post is good but a bit off topic for your problem (no offense Paiste)
The EST controls the spark as you already know. If the light is on, it wil normally start in limp mode. Really retarded timing, runs like ****, like ur running on a few cylinders.
If its not starting I bet my left testicle that the EST is preventing it getting spark.
The EST is a **** incosistant system. It can easily be swapped for a Electronic Dissy of a blue motor or a EFI model VK. I was tottally against this, and spent hundrends in trying to make the EST reliable, not to mention hours, and many tows home.
Replaced the Dissy for 50 bux, car runs so smooth, fuel consumption is down, throttle is more repsonsive, best of all it hasnt broken down since.
Where are you located?

sorry tom, got excited there
thanks heaps tom
i'm located in perth
also when my car was running, it had a ticking noise only started off in the morning but the more i drive around it just got louder, i think it could be **** on the lifters but thats my guess
thanks a whole heap mate
oh just another question
is the est hard to take out?
and where could i get this blue motor dizzy from?
and are blue 202 motor parts interchangeable with black 202's

Haha, No probs mate. You gave good advice, but once u've ownded a VK with EST you will understand lol.sorry tom, got excited there
Not sure on the ticking noise, id say as above, possibly a sticky lifter. Also could be the EST setting timing up **** creek, but that would be more of a knock. Also check the obvious like loose hoses, like something rattling.
EST is a piece of **** to take out, I couldnt believe how easy.
Disconnect battery, remove the computer and disconnect the wiring loom from it. I remove the loom and reinstalled the computer so it looks legit if i get pulled over or anything.
Turn the motor to T.D.C, double check the dissy is on TDC aswell, remove, install the blue dissy at TDC, run the wires to the coil.
Time the engine up, mines currently at 12 degree BTDC, but each car will be different, somewhere between 8 and 12 though most likely.
Then run a vacuum line from a ported vac source off the carby, to the Vacuum advance on the dissy.
Ill get the wiring colours for you another time, I cbf'd right now.
You can use the same coil and no need to rewire anything as the anti-diesel solinoid, auto choke, and coil all get 12 volts with the computer removed making the whole job **** easy.
I was recommended by a VK guru to use the VK EFI dissy for the conversion as they have a slightly better advance curve.
Hope that all makes sense (its late, ive had 20 hours sleep all week), if it doesnt feel free to ask questions. I took some photos of my conversion and hope to get a workguide up when I have some spare time.
im going to get a blue motor dizzy tomorrow then take the est out
ill tell you how it goes
thanks for the big help guys
