Does any one know where to get an uprated oil pump spring from? I've tried Moss but they say they are discontinued (Moss part no. STR560). Also tried Fitchetts.

tried S&S Preparations? They're mainly TR7, but I guess the part is the same.<br>

Hart Racing (Stags). I believe they use a stronger spring.<br>

Thanks guys, I phoned S&S but they didn't have one so rang Tony Hart. I'm glad I did now, as he advised not to do it (well maybe on a worn engine). He says they only run their racing Stags up to around 50psi.

That seems remarkeably low for an under load figure. Mines anywhere between 35 and 70.<br>

I thought that was a bit low too, as I mentioned mine was 70 to 75 psi. Mine had recently dropped to around 60 though but still not bad.

My 1850 never reads above 50 or below 35. Within tollerance?<br>

If my Sprint never read above 50 I would be thinking maybe big ends and/or mains or deffo something worn, maybe pump. I would assume similar for an 1850.

the oil pressure stated in the haynes is 40-60psi at 2000 rpm for both 1850 and Sprint engines.

John I've seen yours hitting the relief valve nice and early. That's all you want to see.<br>
<br>
You dont want it too high or it will blow the oil pump seals.<br>
<br>
60 is quite enough....<br>
I'd be happy with 50 on a stag V8 as its got more bearings to blow it out.<br>
<br>
My p6 V8 is 25 at cruise and no knocks...<br>

Well so says the gauge!

When it's cold, maybe!

On the Stag engine because of the single timing chain a uprated pump/spring will put extra strain on the tensonier and chain causing premature chain failure if not checked regularly.<br>

From the Stag man himself (Not me).

The timing chain tensioners dont have an oil feed nowadays....welll the last few I have done dont and with no ill effects. Even if they did i dont see how some oil squirting through a hole is going to force the tensioner out....it surely only ratchets out when the chain is slack.<br>

<br>
That's because they all steered toward's timing belt's.<br>
<br>
Having served my apprenticeship with Mazda Car's I'm totally disagree with you.<br>

All use a tensoiner with a click type adjuster that is pushed out by a small oil hole drilled into the block that feed's the tensioner.<br>
Sure the Stag use's the same set up.<br>
<br>
It just isn't going to adjust itself when the chain goe's slack.<br>
<br>
On Drug's I very much doubt it<br>
