[Marks DTM Calib]

Deal done on a set of known good lifters.

Oil should be fine....it will only take 3 hours or so to fit them and jobs a good un

Not sure I understand why letting it roast would/could quieten down more than running for a few mins (surely after a few mins, the oil should have pumped up lifters (as I assume that lifters aren't clogged with old oil, given the oil service strategy))?

But, give it a ragging and the oil pressure runs higher until the pressure relief opens

now the saying

Ow, those plug leads are chuffing huge, what yah gonna do, relocate the dis pack under the passenger seat.

Its had a few of them in its time...

Can I quote that next time the passenger seat moans "Slow Down!"

If you've gotta take plenum off, can you slap originals back on (they were in boot iirc), then I can return those leads to 2woody

Sure, no problem

Its back together and running.

No fault codes

No exhaust tick

A light tap noise can be heard, I have heard worse though

Injector cutoff test done......all cylinders firing, tap noise does not change in volume.....this effectively rules out the bottom end as the lack of firing on a cylinder would reduce the load on little and big end bearings hence the noice generaly stops or at least significantly quietens down under this test.
Now, I did notice a slightyly weak follower on No 1 cylinder inlet valve no 2.....

So.....2 choices.....get it stinking hot and see if it quietens down or (and the prefered choice), swap the followers on No1 bank.

I re-read the last pages.. I find this quite interesting..

If you know how to use a diagnostic tool well.....you can do loads of tests even on mechanical bits

I do hope this car hasn't been towed all the way to Nottingham for a new lifter. (Well, I do, of course...)  :-/

When does it not have a good ragging in TB's ownership? 

[Lazydocker]

Fantastic news... Sounds like the silver bullet will be back on the road soon

[TheBoy]

Are we saying that the majority of the noise was from EGR, with a helping hand from a lazy follower?

so do I. In fact I'd say that's wrong. At idle, probably 80% of the load a big end sees is rotational and not firing-load induced. at maximum speed, the inertial load will be 99+% of the total load.
