6n, fitting GT camshaft

[neb]

just fitted one to my mk4 1.0 8v, but im pretty sure its the same for all the them. i turned the camshaft pulley over until its lined up with the orignal timing mark, it should be firing on n.o 1 piston so both lobes on the camshaft are pointing up. then remove the original camshaft, replace it with the GT cam with the lobes in the same position, put the pulley back on, slackened the tensioner then lined up the bottom pulley with its timing mark (should be correct position already), slide the belt back on and tighten the tensioner making sure the guides line up. To make sure all is a ok turn the engine over on the bottom pulley.

with the bottom pulley on the timing marks (no 1 piston firing) it should be somewhere around here

thanks to me pops and jarno for helping me

what does this do?

Gives more BHP and torque The cam from a mk3 GT with enginecode 3F is the "hottest" hydro-cam VW ever build for a 8v Polo engine, which can be mounted in any 8v Polo engine, so it's the easiest and cheapest slight tune-up of your engine

your welcome m8, already started the engine? Didn't have to time the belt and ignition by hand? (I hope you've checked this both before your started the engine, to make sure your valves won't be hitting your pistons which would have been the issue if I used the original markings when I installed my old 3F camshaft)

yep turned the engine over by hand before starting, i ran it and all seemed fine but i still had the ignition timing on the standard position.
it was abit of luck as the belt timing was spot on first time!

Didn't use the trick with the long screwdriver throught the spark-plug-hole? With that you can really "fine-tune" the timing of the opening of the inletvalves, to make the engine suck in as much air/fuel mixture as possible

how much can you buy this for. and where from??? id ike to do ths to mine :O

cheers, i'll give it a go. ran it properly today and it definately gives you more oomph past 2500rpm.
i got mine for £35 posted off of hardhitter, they come up on ebay sometimes as well

nice. glad to know about this. just gota get my hands on one now lol.

do you need to alter anything else to make it fit? and does it wear anything down or owt faster?? if im making sence...

It's got a longer duration, which means your valves will by opened longer, therefor making it easier to suck in (more) air-fuel mixture and breath out the exhaust gasses, giving you mroe power and torque. No further adjustments needed here, just a proper fitting and checking of the ignition and timing belt

ooo i c. guess i need to get a new timing belt first then haha. mines done lyk 67000 miles :O gota wait till next mounfs payment first though before i can afford to change it. this is a pretty good upgrade to do. ill be fitting this deffo. pretty cheap. thanks for posting this neb!

you know if i went to a scrappers. cus i know a VW one. what car and model would i look for so i could get one of these off?? i own a 1997 1.4 8 valve polo. think its the 6n. but i dont have a clue what 6n or 6n2 stand for lol. so i wudnt no which it is.

This cam comes out of the engine from a Polo 2F (the square model with square headlights), take the GT version, and make sure it has the engine code 3F (is always written on the sticker on the timingbeltcover on the engine).

And if you change your belt, just change your waterpump/coolantpump too, while your at it, saves you lot of work in couple of k miles (don't forget to change the tightener too )

[Hardcore]

ok mate. thanks. do i need to alter the water pump is it highyly important :S

ill do it anyway though. what am i looking for? a bigger one??

[ronny]

does this make alot of diffrence to a 1.4 8v engine is it worth it

[JarnoVWPolo6N]

Nope, same one, but original ones have plastic interior, new ones metal which is stronger and lasts longer. Also the old belt will have worn out the pulley of the old coolantpump, so installing a new belt will f(ck up the pulley of the old coolantpump very quickly, so changing it right along only gives advantages (except for the price, but better do it now then later on )


"Ronny yes, it makes a really noticebly difference, I could notice it good on my 1.3 8v ADX engine, and m8 of mine is running my old 3F GT cam now in his 1.4 8v AEX mk4, he´s excited too
