Hi *
My GTi (4g67) have problems in some range of rpm (3-4 krpm and above 5.2 krpm). In that range engine is very loud. All of that occured after timing belt replacement. That job was done by my local mechanic, and after my complaining he was dealing with it for few times but always unsuccessfully. Is there a problem because of only timebelt replacement (not tensioners) or there is basic setup of timing belt? I have found a lot of instructions for 4g63 timing belt replacement but not for 4g67 (it's 1.8 16v, 136HP). As I could see that those two engines differs only in cylinder dimensions, head of engine is same? Locations of camshaft, tensioners and other stuff regarding timing belt seems to be same- so can I follow procedure for 4g63? There is also two versions of 4g63, which one is alike my engine Also engine have loss of compression on 4-th cylinder and my mechanic says that problem is with some warn valves. Strange for me is that engine was runing not perfect but ok, before timing belt replacement of course.... thx for all suggestions...
p.s-sorry for bad english
