Hey guys, I’m hoping someone can help me here as things have got a bit out of control.
My MKV Gti had a faint engine rattle, nothing too bad but the engine has done 167,000kms so... I bought an intake cam revB and had this fitted along with my new hpfp from hpfpupgrade, oem cam follower and new timing belt.
Drove it for half a day and then this massive rattle started from the timing belt side (left side) of the engine. Took it back to my VW mechanic and they stripped it down far enough that they could still run the engine and diagnose the rattle. The VW mechanic showed me how it’s actually coming from the timing chain that goes between the camshaft adjuster and the intake cam on the right side of the engine. He thinks it’s wear is now aggravated by the new intake cam sprocket. When he dis-connected the oil pressure switch from the Camshaft Adjuster it went quieter, meaning that when the Camshaft Adjuster tightens at revs to turn the intake cam the chain gets tighter and the noise goes away.
The annoying thing is, the old cam which came out was already a revB (which I didn’t know) but the mechanic reckons that the chain could be worn in with the cog on the old intake cam.
Long story short they are now suggesting that I replace the timing chain, the camshaft adjuster and the timing chain tensioner. Bad news these things cost $1,500 from VW, good news is they only cost$500 from ECS tuning, but this means I’ll be carless for a couple of weeks.
Has anyone had this issue before?
Do you think maybe just the tensioner would suffice?
Cheers
