Oil Pump Adapter

[peter dowdle]

Thank you both . Mine has been welded once earlier in its life and recently for me. The problem is the thread is tapered and as you tighten the pipe fitting it puts undue pressure on the 50 year old cast iron causing it to crack. One option is to bore the thread out and re tap with a non tapered thread, using an O ring to seal the oil.

I rang the factory and they advised no new stock but may have a second hand one. Still waiting for confirmation.

Elko Performance Parts in Melbourne (chrysler specialists ) know of a kit out of the USA that would have possibly the right adapter, but you have to buy the whole setup just to get the part you need.

The JOYS of bristol ownership.

I have just been advised that Bristol have a second hand one for me

That's good news Peter!
It seems it is a surprisingly rare part.

Hi Thor :-)
It's been a while!

On mine it is the pump body that is cracked, but I think Peter's problem is with the adapter plate (see picture).

If originality was not a concern it is easy top buy a replacement (higher performance) pump, plus a remote filter kit for considerably less than £500.

Kevin yes its my adapter plate that is broken where the oil line fitting screws into the cast housing as seen on the left of your photo.

Yes you can buy replacement pumps either standard , high volume or high pressure but your comment on buying a remote oil filter is also correct but you still need the item I have been chasing.

Some of the high pressure or hi volume pumps are longer in the body . There is very little clearance between the pump with adapter attached and the cross member. Approach with care.

To fit any replacement pump you have to either remove the motor or as I did support the motor with a trolley jack and remove the 2 engine mount bolts and with care jack the motor up high enough to enable the oil pump retaining bolts to be removed

Good point Peter about the clearance!

I have a Melling M63HV pump on my car now and I suspect the oil pump cover has been removed and replaced with something like the item shown in the attached image - it's a Milodon Billet Aluminum Oil Pump Cover - 21225. They can be bought from several sources in the US for about US$220.

This would solve the problem. The intake on the right hand side would be capped and the two ports on the left hand side go to the remote filter.


Regards,
Kevin

Seem exactly what I was chasing . Is it fitted to your car in place of the bristol adapter? Why my chrysler contact didnt know of it ? How did you get onto this setup ?

Do you have the third inlet blocked off?
