Removing sump

[Cerrone]

I’m replacing my sump gasket this week and just trying to find out the best way to do it as I’ve read it’s a bit of a pain. Just looking for any tips or guides, stuff to watch out for and any bolts that are hidden! Any help is appreciated thank you!

dog bone off, lift engine right up and stick a block under the mount bracket on drivers side.

dog bone completely off? And how high are we talking with the engine?

 

[bloke]

Yup, off. As high as it will go.

Fit arp bolts whilst it's off iirc

and mod the oil pressure relief valve.

Whats the mod for the prv ? Shim it ? I used to do it to the gtts for more oil pressure when hot.

Amy more details on this and what are the benefits?

Are there any guides on here or information about why you would do it? @bloke

Pin sits in a groove on the bung, need another groove at 90 deg to the original one and not as deep.

That will make sense when you see it, if it doesn't make sense then you shouldn't be doing it!!!!

Puts more preload on the spring so should hopefully up the pressure that it takes to open the oprv and also help it in not actually sticking open.

Ill have a look at that soon @bloke as need to take sump off. Any hot oil pressure readings before and after ? One thing i found after shimming the prv on the old r5gtt c1j was that the cold oil pressure goes through the roof but only seen a slight increase when hot 5lbs or so however its an old design compared to the f4r.

Don't think I've done one that's actually had a gauge in the car sorry.
