I've got myself a gti-6 3 months ago, i bought it with a ticking/tapping sound. seller told me it was a lifter that was not working correctly and it needed to be replaced. i got 1500,- of the original price because of it.
I brought it to a local engine rebuilder and he replaced all the lifters for me, he found out the crankshaft pulley was not correct when trying to time it up again, it had slid on the rubber so he replaced that as well. when he was done he started the engine and he heard the ticking again. Now he took of the head , rebuild it, replaced the bend valves and bearings of the (i think) crankshaft.
Now when i start it, it runs fine when cold, but after about 3 minutes when i hit the clutch it starts to tick slightly but after a while as the engine gets warmer the ticking gets louder and sounds like a diesel. weird thing is that it's there when it gets warm and when it's cold i can hear it slightly when i put my foot on the clutch (pushing it down) and when i give just a little bit of gas. when it gets warm, the ticking is there all the time.
I went to another mechanic and he told me it could be another faulty lifter. but i just don't know what to do, i spend quit a bit already and it's still not gone. therefore i've searched through this forum and can't really get an clear answer, but i do notice there are some specialists on here, while i can't find any in Holland. i hope my english is well enough for you to understand what is going on. i love the car, i think it's the best looking hot hatch ever made. but it makes me look like a fool when it sounds like an old diesel.
Thanks in advance.
