Bumble is poorly.
To give you some background on this.... I've done around 35000 miles since rebuild back in Feb 2010.
All has been good, we've seen a host of different setups together on the 1.8t platform, and it's all been good.
However - I have never been able to get rid of this annoying lifter tap despite having the head rebuild several times over the last 2 years, it's always been there.
Only used to moan when cold, then would go away once warm, but always been annoying. I've ignored it for about 12 months now as it wasn't that annoying and all has been well.....
...Until about a week ago.
She was due a service anyway, and my tapping was getting more annoying, and lasting longer. So I gave it a service as you do, slapped a flush through it for good measure expecting everything to be lovely.
Tapping still there, worse than it has been ever. Arse.
So, I decide it must be time to change the lifters. Used my stethoscope to try and locate which lifter was rattling and it sounded more prominent from the inlet side.
Swapped out the inlet lifters last night expecting all to be well. (A surprisingly easy job as it turns out - exhaust much harder).
Engine fires up and new lifters are chattering away from where they are dry-ish. Lets put it this way, the sound of those lifters was nothing like the noise I can hear... which made me a tad concerned.
Led down on the floor and put the stethoscope tip on the sump.... oh dear... the noise is very evident and clearly not coming from the top end...
