I was quite concerned about that also it seem doubling the pick up seal is a good idea which is what I did with myne I also put the original oil pump back in and didnt bother with a new one after all the problems as they seem to be cheeply made

im not 100% sure but i know its a problem with oil pressure when using the power. im pretty sure Alan (barnsley bll) had a simalar problem on his engine build.

best off speaking to Tim as he knows the problem and how to resolve it

get both checked dave. if you can afford to take this opertunity to get the crank smf clutch lightened and balanced. if its oil pump failure who supplied the pump. if the engine builder they havnt got a leg to stand on just like me

he knows more than most about these engines and associated problems, i have used his services and seen some of the cars he has built, very talented bloke

the oil pump came as part of the engine - it was supposedly new & it looked new at the time.

Perhaps a lighter crank would be suitable.

If it was a new pump, I would be very concerned, there is definitely an issue with the new Volvo pumps. Have a chat with Tim.

I never had these problems with the v70 2.5t .i would use your spare crank and get the engine sorted with the oil pump in the other engine if its a good one .

so if its oil pump failure wouldnt that make them liable. saying that if oil pump failed youd think the top end would go first

If the pump failed then yes the top end would rattle its tits off.but I have never heard of a Volvo pump failing to be honest .but if peeps are saying the new pumps are rubbish then I would put the pump out of the engine .but check it for play first of course .once this engine has been built the last thing dave needs is a inferior pump in there.

Perhaps I wasn't clear - the donor engine came off ebay - sold as it was with new cam belt & new oil pump.

Motorcast in Wem used that engine as the starting point - it was completely reworked from top to bottom.

The oil pump was part of the original package I gave to Motorcast.

im wary of hearsay on forum. best taking some things with a pinch of salt. a lot of coments get made on forums by people who have no knolodge or experience with cars then then they read a few threads and then try to offer advise on what theyve read. ill only offer advise on something i have first hand experience of.

Thats why i said to Dave too speak to the man that knows about these things, as far as i can see its 1 of 2 things oil starvation causing excess heat in the shell or simply a bad cast shell.
