Where Do I Go To Get An Oil Pump?

[SECURITY]

im not keeping the motor for long, thats the only reason im not doing it that way. the motor is just to get me around for the time being till i can build a 30/26 which is where my money will be well spent.

and even the way ive done it, you will all see it handle the runs and track days well

If you wanted a cheap rebuild you should take the donk out , strip it and carefully check everything then only replace what ever is warn/damaged . You can't just hone it out and hope for the best, the pistons you used ( the second hand ones ) you should have measured them to make ure the piston to bore clearance is not to big .

Just because they came out of an rb25 don't think they are the same, don't forget they are graded so they do vary a bit, then you hone it as well .

You can't realy clean the bore after honing on the car you have to scrub it with soapy water to make sure you don't leave any honing stuff there that will wear the bore very quick . You can't measure the bearing clearances on the car the crank has to come out put on the lathe to check the runout to make sure its within specs .

If as you say the bearings were like new you would have been better of to leave them rather than change them and not check how much clearance you have there .You left the old pistons there and it was pinging so why not the old bearings? You should have at least pulled the oil pump appart to check for scoremarls and wear .

Feel free to pm if you want but this time do it the right way, believe me you can't cut corners and don't forget you will need a new gasket set and a new h/gasket dont use the old one again .

Some people do everything right and they still have problems, imagine when you try to cut corners !

Good luck with it ..

the pistons i used were the same dia as the ones ive got in there, the bore didnt increase in dia. by much at all, not even half a mm.

we did wash the bores out then blowed them out thoroughly. same with the crank.

the 4/6 pistons were replaced.

anyways, im leaving all decisions to my bro in law.

the matter is now closed.

I hope you didnt increase the bore size by half a mm, if you did the pistons would swim in there, actualy even a few hundrenths of a mm is to much ! I honesly dont know how you washed the block in the car.
