URGENT oil pressure stop engine

[doylebros]

Oh  I had it in my head that 2 bar was roughly right. Perhaps it will be better with the starter motor? Is there any hope in the fact that they were all roughly the same?

To tell you the truth Pesky I've never checked the value when hand cranking - if it does two full turns and it realigns with all my marks I go straight to the starter but don't I don't let it start!
Then I check if the oil light goes out and listen for mechanical noises I don't expect.
Then I go for cylinder values - personally I expect you to have to remove the head as I expect you'll get it running but rough in its running. However, that lets plenty evaluation to be undertaken and a realistic repair cost to be achieved.

Once again well done as a previous poster stated plenty would have given up by now

Well.... atmospheric is about 14.7 PSI. Mulitple that by the compression ratio of your engine... 9.8?


14.7*9.8~= 144psi

You've lost me, is that a good or a bad thing for me

Thanks mate appreciate it. I don't want to let it beat me  I guess we'll see...

Next step put everything back together and compression test with starter motor, but with fuel pump fuse removed?

[doylebros]

Just YouTube compression testing it will give you a how to.

Over 100psi and 10% of each other will mean it will run until tomorrow 

[rich83]

  I dont know.

But I think thats roughly how you calculate what PSI you should be seeing on a compression test

Oh, so like @Dan_FR says I should be seeing 150ish plus.

I'm just hoping that with the starter motor it makes that.

We'll see tomorrow if the girlfriend lets me have another evening 

Once again thanks for everyone's help, another bit of progress 

[rich83]

How many times did you rotate the crank to test compression?

[r5gtt]

Never heard of a compression test being carried out by hand 
As doylebros said two full turns and if all lines up then crank it and yes with fuel fuse out if that makes you feel any better. if the plugs are out which they all should be when carrying out a compression test it won't start anyways

[Pesky jones]

Er more then twice probably, but didnt actually count to be honest @rich83

As @r5gtt says it doesnt sound like its very common, so hopefully proper compression test will yield better results

[rich83]

Looks like you are just gonna have to clench your teeth and try and crank it 

[r5gtt]

@rich83 he'll be fine and so will the car   

I'll be reading this on the plane tomorrow night so make it good pesky 

[doylebros]

The easiest way possible for you but make sure there's nothing loose that can get sucked into the intake if you do it with the cover off and have nothing lying about in the engine bay tool wise etc.

[BenJ]

Cable tie a thin sock or some tights over the intake in case you're afraid or likely to get something go in. Belt and braces and that :)

Ok cheers guys will do.

Cam chain cover back on, rocker cover back on (took a little persuading with the rear hoses) and pcv back on.

But then this happened, I hardly touched it, honest!



Anyone know the part number, and how I go about attaching a new one at the lower connection below the manifold?

[Dan_FR]

Just tape it up for now - very common - becomes incredibly brittle with age - around £20 from the dealer

Has the same type of squeeze to release type clip on the engine block although it is fiddly to get to. New pipe is a lot more flexible and can be routed around the HPFP pipes and fitted into place fairly easily

[Pesky jones]

Thanks dan will do.

Any tips on fitting new one?
