URGENT oil pressure stop engine

[Pesky jones]

All done. Lets see what happens...

[rich83]

Is the cable cover still not right?

[Pesky jones]

Sorry rich, cable cover?

[rich83]

Cam cover

[Pesky jones]

I replaced the vac pump, and thr valve covers gasket so hopefully it should be ok now, fingers crossed no more oil leaks

[Pesky jones]

Been 24 hours and done some motor way miles, no sign of any oil, must have been the vac pump

[rich83]

It did look very oily when I took a look. Hopefully thats got it.

Good job!

Well done on your progress and I could 't make any noises out in your video which worried me.

Why didn't you remove the two PCV bolts which are damaged when you had it stripped down or are you saying your only using two of the four bolts and these damaged bolts aren't in the head?

Thanks, the noise is only really audible from 15 seconds onwards, but it may just be in my head

Out of the four pcv bolts, there are only two holding it on. The other two have had the heads sheer off, with the shafts still remaining in the cam cover. I did look at removing them, but the shaft diameter is so small im not sure an easy out (cente punch and lhs thread bit) would work. Rich suggested using a dremel with a small cutting disk which would slightlt cut the plastic of the valve cover but not too badly and then use a flathead to remove them, but I dont have a cutting disc attachment. Ive left it for now, because it seems to have a good seal even with only two bolts. I did a pcv test with the dipstick and it passed so ive assumed its still functional.

I think now ive done everything I can in a mechanical sense to ensure the engine is working correctly, im going to do some logs to check performance.

I think ill use advanced measuring blocks to measure actual and requested boost, and fuel rail pressure, as well as mass air flow rate and rpm. Any others to measure to help confirm the performance? It is rtech stage one if that bares any relevance. @dazza you're clued up on this arent you?

Thanks guys

I followed this i think they have most things covered.

I think I can maybe just about hear something...... No idea what it could be though
Standard airbox? Any leak from the PCV should be highlighted through slightly higher than normal fuel trims (Block 032 - no logging just a static check - do not clear fault codes as it also clear the trims and they will take several miles of mixed driving  to re-adapt)

As for logging, it depends what you want to check? mechanical side of what you've done or just general health data logging? APRs guide isn't bad although the misfire diagnosis stuff isn't needed unless you have a misfire problem

Some of the things I normally log across various runs include:

normal blocks 115, 020 114

Advanced:
Engine RPM in each log as a reference.....
Ignition-timing angle (Group 3)
Lambda - both specified and current, (Group31)
Throttle drive - angle sensor 1 (group54)
Injection timing (Group 101)
Low pressure fuel pump (103)
N75 (114)
Boost - specified and actual (115)
High pressure - rail (230)
Intake G/s (003),
Ignition timing (003)
Timing pull/correction (020 - all 4)
Lambda regulator (001 I think)

Could be more that are worth doing, but I use these when doing a general health check on mine

Just got myself a VCDS cable and will have a play with those below, exactly what I was going to post about 

Any other things worth looking at when doing a health check? 

Cheers

[Pesky jones]

Thanks @Dan_FR will look at those. Im just going to do a third gear from 1500 upwards as it will be too fast in fourth I think. Will also check the fuel trim. Know what it should be on an axx?

Is the noise you can hear like a surging noise that comes and goes?

[Pesky jones]

The surging can be really apparent from inside the car but impossible to record. I oculd hear it quite loudly yesterday in the car after giving it some beans. Ive listened to the video again and you really need to turn up the volume to hear it. @doylebros maybe give it another go? Remember its the last five seconds that you can properley hear it @Dan_FR do you know what normal fuel trim shouls be? Or is a case of requested and actual and ill be able to see myself.

Its the last issue on this whole topic, and ideally I really want to sort it haha. It might turn out thats its normal but I doubt it. Thanks.
