When ever was it exciting . Watch moto gp for exciting

I don't know the set up in your landy , but i would think if you plumbed the pipe from the carb tower to the expansion bottle it would flood , the expansion bottle is just a space for the expanded liquid to migrate to and return to the system as it cools . The flow from that carb tower outlet is qui...

Sorry Harvey , didn't know you were here

The pipe out of the top of the carb tower ( blocked off with a short hose and bolt ) needs to be plumbed into the top of the header tank , it allows flow and prevents air lock in the tower , helping keep the carbs cool and avoid vaporisation

Hi Wilson . I don't usually post on here other than to ask questions , i leave the advising to the regulars . Seeing what your putting the motor into and with a BW auto behind it you might be interested in my P6 spec ( i've recently got it where i want it ) From the inside out . 3.9 cam new standard...

Thanks guys . I don't do many miles in Her , She gets used a couple of times a week , Shopping and shows , spot of rumbling around at the weekends . As for the honing marks , they are feint , but still viseable . The pistons looked standard , as in no over size markings . But who knows with a 40 yea...

Thanks for nice comments and advice guys . It was only a top end overhaul though , the engine's only done 68k i could see honing marks on the bores . So piston / rings not touched . I'll certainly give it a thrash though

Hi Guys . As above , i,ve done a bit more work to my P6 . I posted on here a year or so ago when i uprated the oil pump and timing gears . That was as far as i could afford to go at that time . The intention was always to go back and fit SD1 heads , new cam/lifters . Over the last few weeks that is ...

Thanks Guys i'm happy again now

I'm pretty certain 20/50 was the factory spec oil for the UK up until '83 when it changed to 10/40. I know it's the right oil , just wondering about running it that hard from cold being thicker . I know other p6 people have , but they didn't read this first . Wishing i hadn't now ! ignorance being ...

Hi all . Been following this with interest as i'm about to fit a 3.9 cam and lifters , Along with rebuilt heads SD1 It's all documented on the classic rover forum here http://www.classicroverforum.net/viewtopic.php?f=5&t=12365&start=0 ( Hi P6 people on here :D ) Any hoo . I have it all worke...

Hi i posted the same question on here a month or so ago . I still haven't managed to find one . If you do track down a supplier will you post back on here please

Thanks Perry .
I have looked at their ebay site and can't find one , although some time ago it was on there . May have to try a good old fashioned phone call

So no one can help me find a tadpole pressure relief valve for my old v8 then

Edit ,

Thanks guys ,
I fitted the pump upgrade around a year ago , and the pressure/flow is good . What i am looking for is the tadpole type of relief valve as mine sticks shut sometimes .
