I have finally decided to remove my top manifold and Rocker cover of my 16V KR. With Rubjonny's help today I will be checking if the two dots on the cam pulley line up at tdc.
I just wanted to find out whether its simple to remove the head to de-cock it... and anything else that you guys may recommend.... I am hoping there is a step by step procedure to remove the drive chain, head e.t.c.
The car was running sluggish prior to this and finally decided to open into it... I messed around with the timing and still was sluggish, so now I am contemplating whether to just check the dots lining up and replacing the injectors or take the head out and re-work it.....
Thanks guys....

Taking the head off is not that difficult but not something to be considered lightly. You need to do a lot of prep first like getting ALL the tools and parts e.g. gasket sets, new head bolts etc. Plus, all sorts of things can go wrong when taking the head off... A manifold stud could shear off for example. Therefore, unless you've got poor compression (get a test done), I wouldn't take the head off just to de-coke it.
In terms of a procedure, haynes has a very good step-by-step process.
IMO... Unless you've got smoke and/or poor compression, or head gasket issues, the sluggishness will probably be due to something much less serious like a temp sensor, timing, fuel pressure, the WUR, CO2 setting, or an ignition issue... Something like that.
Good luck!

just run her on v-power for a while, some fotre upper valve treatment, full service inc fuel filter, plugs. also look into the 'water trick'. that will clean the engine up a treat

Water trick?????? Wasssat?! :huh:
-
Ok, there car is not smokey at all. Just very sluggish.. I will now just sand blast the rocker cover and top manifold and spray it, and then put it back on, or even just put in kent cams... not sure about the way to do it....
What is the water trick?
Thanks
-
use the search! once the engine is warm, you sip up water through a breather hose, effectively steam cleaning the bores.it sounds scary, but its not.
i did it on my old pb. 160k. once the head was off the bores and valves were as new
-
Hey sounds scary but promising. I searched for the process, but was unsuccessful. Can you please forward the link.
Thanks

no probs when i did it :smiley:

ha that sounds SO wrong!!! i might try it...cheers for the link!! :grin:

that is utter bo11ox
how can you steam clean carbon off with 1 pint of water !!!!!!
i've seen loads of K series moters that have sucked ALL there cooland into the cylinder and there is soooo much carbon still in there
i have used injector cleaner instead of water and it cured a missfire (sticky valve) on a zetec motor
i personally wont be doing that to my golf
-
I might give it a shot. Correct me if I am wrong, I remove one vacume pipe underneath the throttle body, and dip in a pint of water and keep the revs up until its sucked it all.
Do I use cold or hot water? Would you recommend boiling water? would it clean it more?
I am not sure what the problem is on my car, but its really sluggish. I will try this then do a oil/filter change, Fuel filter change and airfilter, sparks...
I have never changed the temperature sensors or any sensors, but have heard that one of the temperature sensors also help the acceleration is this correct?
Is there a diagram of where what sensor is?
Thanks....

Sweet looking valver there raks :cool:

cold water matey. the vacume tube that goes to the airbox is what i used :smiley:

I have never tried this myself, but I can see how the theory works. Water boils at 100 degrees, more if under pressure. So steam, under pressure will be cosiderably hotter (super heated steam) and will carve its way through most things, even baked on carbon.
You can use redex by pouring a little down the bores first and leaving for a few hours to loosen up the carbon on the pistons. This will also get into the rings and may help remove the gummy deposits in the piston ring grooves. Then run the engine up to temp and try the water trick. You will probably remove alot more carbon.

worked a dream on my old 1.6 driver, lots of carbon build up due to faulty auto choke. after a bit of water therapy the car drove smooth as anything and left a foot long black sooty stain on my driveway.
Just becasue you didnt see it on a k-series engine doesnt mean it doesnt work, do you know how much water was getting into the cylinder? Also ask a few other people who have done a cylinder head after a water into cylinder leak, they do often end up with 1 pot totally spotless ;)
-
Thanks George... Its clean but hard keeping it clean....
I will try this as soon as I refit the rocker cover and top manifold.... I am still a little confused, out of the two vacume tubes that connect under the throttle body, do i dip the one going to the airbox into the water right ?
I am looking forward to doing this, would you recommend doing this like a every year thing?
Thanks guys for your help....

yeah thats right, tbh injection cars dont really suffer from carbon build up as badly as carbs do, i did it on my gti and it made sod all difference. worth a try though not like it'll cost you owt!

I was just speaking to TSR about the car being sluggish and they told me that they have a doubt on the fuel delivery and that would restrict the cars performance. They did say bring the car to them with a labour rate of £50/hour and should take about 2 hours tops but its the 4 hour journey putting me off...
I wonder if there are ways to check this myself..? I am sure rubjonny's knows....? Could it be the fuel pump...?

the kjet seems to be tempromental and really needs to be set up by experts
-
only way to check fuel pressure is with a proper k-jet pressure test kit, with a bit of know-how and some bodging you could knock up something but make suyre the fuel connections are good as its gotta stand up to at least 6bar for a good safety margin. I picked up a genuine VAG kit for peanuts off ebay, looks like this:

Yeh you prob right...
Once I do this water trick and a engine flush and oil change if still the same I will then take it down to TSR, atleast that way I know that the car will be running spot on... and they can also check other possible things for me....
Thanks guys....

Today i refitted the rocker cover and top manifold and warmed the car up and did the water trick, I probably used a little less than a pint of water, but cannot notice any difference. I was considering taking the car to TSR but am getting put of the 400miles round trip...
I have come accross AmD Technik - http://www.amdessex.com/about.cfm, their diagnostic charge is £60.00 and then £138.00 for Rolling Road tune, but would just do the rolling road if they figure out the problem first.
I am just wondering whether any1 has heard of them. I am only considering them as they are much closer and easier....

i gave my 8v a service today. oil, filters (inc fuel), plugs, cap rotor, coolant etc. iv
it feels like a new car. acceleration semms to have improved :smiley: , but i have been neglecting her of late due to the weather.
fuel pressure check, timing and service.
should not need a rr tune? unless your just interested to find out she's making. i did, and was a little disappointed :sad:
-
The reason I know my car is no where near the 7.5s mark that it should be. It is very sluggish and more to the fact a friends standard mk2 16V is much quicker off the line and also from any speed.... I am 99% sure I have a fuel delivery problem....
Just need some1 local to help....
