VX Sump and oil question

[alan c]

I am going to change the oil in my wet sumped VX over the weekend and replace the foam at the same time.

Two questions:-

1 I see people talking about using a sealant in places - what type of sealant should I get? I understand where I need to apply it, I assume its a smear only of the correct stuff.

2 An old question I know - Oil I have seen several different types of oil recomended but I have 10l of Mobil One 0/40. I see some people use this, will it be 'OK' for road use only or should I really go and get something else?

Hi,

 

I don´t know Mobil One 1/40 is this Mobil 1 0W-40?

The correct sealant to use is either Loctite 598 or the GM sealant from a Vx main dealer. If you do a search on here you might find the GM part number. I think you can get the Loctite from Halfords.

 

You'll also find endless posts from the past regarding Vx engines and oil. I use Millers 10/60.

 

Edited to say that the 0 grade is likely to be too thin for a Vx on hydraulic cam followers and you'll have a clattery engine when its hot. The recommended Mobil 1 was 15/50.

Paul,

 

Thanks I will go and buy some different oil, the other stuff can go in the tin tops.

And just to be difficult, I use 0/40 and yes, it's tappety when hot so will probably go thicker on the next change. I haven't needed to use any sealant on mine.

Sorry one final question but am I correct in thinking that it will take approc 5l?

Alan,

 

Another thing to check whilst the sump is off is that the oil pick up pipe isn't touching the bottom of the sump pan as mine was and starving the engine of oil hence my top end rattle

 

cheers Neil

Hi Alan

 

You should find it's nearer to 4l that is needed.

Thanks guys.

I will check the pick up but not having any problems right now so plan is to put it back as it is.

Thanks to everyone for all of the advice, job now done. I have to say it is not a job I intend to repeat quickly on my own with the car on stands. Definately need more space to work and an extra pair of hands would have been useful.

The foam baffle was very brittle but all in one piece. There was no need for any mods to the oil pick up, some one has been there before me and done that.

Its been tested as well went back to normal pressure more or less immediately and there are no signs of any leaks.
