As Gary said, I went over today with the intention of sorting the whys as to the low oil pressure and to have a look the on board video/data logs.

After having a quick discussion it was out with the grill, off with the bonnet and a hair cut for the engine. With the blower off we can get the the oil pressure sender far easier.

Part of the plan too was to check the valve clearances and this is where it all went horribly wrong. Nothing discernible in this image however the video tells the tale.

This is the eye watering part. All we have done here is remove the rocker covers :shock:

Now that it's become apparent the cam has lost a lot of lobe, it's off with the inlet, revealing another issue.

And there it was that we downed tools for the day. Stay tuned for the next exciting instalment at a time and date to be determined.

Ah, the old cheesium camshaft.
I had some fears that we may have lost some lobe on the bellytank, but when I checked, they were all there
Which was surprising when you consider the amount of lift and the technology involved in our solid roller lifters
(standard lifters with the hydraulic bit removed and a 5/16th ball inserted)
We also had some water in the rocker area of the cylinder heads, but it went away after the next run.
When I get the motor and box back of Goggs, I'll pull it down and see how much we keep

They make it
I make it work

Grumm,

The cam is (was) a Crow Cams steel billet. Other than the bent link on one pair and scarfing of that lifter roller on one edge, at first inspection the rest of the rollers and their bearings in the lifters appear fine.

Time will tell.

What caused all the excessive clearance issues ?

Do you think the damage to the lobe was a cause or symptom of the bent lifter plate

Diluted oil causing lobe failure.

We don't know yet Greg,

We stopped after we had pulled the lifters and the cam is still in the engine and will pull the engine/trans in the next session.

Per the video there were clearance issues on any number of valves, not just the one with the bent link which is on the opposite bank to those videoed. At first inspection the rollers on the lifters (other than the one with the bent link which has picked up on one edge) and the rockers appear to be sound.

Hopefully we will know more when we tear the engine down. For the moment it's all research and supposition.

Cheers,
Rob

Chris,

Would that not also show on the faces of the rollers?

Cheers,
