    Hi there. I have been a member for a while now and not posted anything but have used the mech threads etc for information to help me restore my 1974 Bay window camper.
    I am 5 years into a bare metal restoration. I am now on final assembly.
    Has anybody had experience fitting the CSP banjo bolt which eliminates the rear oil pressure control piston to achieve a full flow oil system please.
    Many thanks JJ1

    I’ve moved your post to Mech Tech to give you a better chance of getting a reply :hattip:
     
  4. Hello!

    Looking at their spec, implies that if you use that method, you have to get rid of the stock oil cooler. Is that really what you want?

    I changed to a CB Maxi 3 oil pump and modified the rear engine support bar with an angle grinder and a welder to clear the hoses for my full flow setup.
    As a way of getting full flow with engine still in the bus and no drilling or tapping the block.

    Snafus with metalwork outside the engine are easier amd quicker to fix.

    As a result, I full flowed my brand new engine in a field at Techenders, simply swapping the stock oil pump for the Maxi 3, the full flow setup remained in the bus from the previous engine.

    And I kept the stock cooler functioning as a result.

    Sorry about the delay in replying the issue is frying my head a little bit. Yes I went onto CSP website and phoned them up in Germany
    and they recommend blocking off the factory oil cooler. This doesn't sound good to me either as I will only have to fit an external one and
    a temperature sensor etc( I am still not sure why you have to remove the factory oil cooler).
    Which all sounds a bit expensive and overkill. I only wanted to fit an external filter.
    EMPI do a similar product (more expensive) and the blurp on there site says nothing about blocking off the factory fitted cooler.
    VW Heritage sell the EMPI one, however if you dig a little deeper the questions and answers section attached to the part indicates the recommendation to remove the stock oil cooler. So I am non the wiser......
    I have looked at CB Performance pumps and phoned the USA yesterday and they just reiterated yes I can use a Maxi pump with an IN/OUT cover plate
    but I will have to modify the moustache bar engine mount.
    This all comes about because the engine builder 'forgot' to drill and tap the case whilst the engine was being rebuilt. Such is life.
    Thanks for all the info. and taking the trouble to reply. Regards
    John

    Thanks for the reply.
    I think this maybe the safest option as there is no ambiguity. How tortuous was the hose run and what fittings did you use exiting the IN/OUT cover plate?
    You wouldn't happen to have a photo of the arrangement would you.
    Many thanks for the info. much appreciated.

  9. Something like this might be best if you're using a cover plate. Getting rid of the stock oil cooler is just crazy. Tapping two galleries in the case is the neatest solution, but sounds like it's not possible for you.

    I mounted my oil filter head on the chassis rail under the rear corner panel, which is pretty straightforward. Use blue Aeroquip hose for the flow and return pipes. It's rated to 150ºC. I just cabled-tied the hoses to the rear backbar.

    Thanks for running out and jacking your van up to take a photo that is beyond helpful. A true gent.
    Nice installation though. I will send back my CSP banjo bolt kit and get the CB Performance pump with IN/OUT cover plate.
    Modifying the moustache bar is right up my street. It's painted but it can be repainted.
    I will post some photos when it is done. although don't hold your breath, this restoration has been a long and arduous one.
    Not to mention expensive, but I don't need to tell anyone on here about things like that!!
    Thanks again.

  11. I had the pic already ;)

    Other cover plates are available - Berg do one. You might want to avoid EMPI. If you're handy with a welder, modding the backbar shouldn't be a prob.

    Thanks for the advice. I will have a look. I will firstly have to pull the oil pump to see if the 'builder' has blocked it off with a plug ( I cannot speak to him as he has
    disappeared.... I was one of the lucky ones to get my bits back!) . Thanks again.
    Cheers

  14. tasty exhaust - what size is it?
    Have you got big bore heat exchangers as well
    Rocker covers also look fancy
     
  15. No, normal exchangers and JK stainless exhaust. I treated myself to CSP rocker covers (with stock cork gaskets). They haven’t dripped so far...

    The heater hoses are the rock-hard stainless CSP ones, as I got tired of the cardboard ones scorching through.

  18. we can ask Eddie to stick a paddling pool in the bar, it may be too cold to have it outside

    I cut away one side of the support bar and used straight fittings.

    The bar was carefully cut and then reinforcing welds were made where the folded support piece still touched the support bar in the left of this picture.

    Anothe view of the cover and the fittings I used, showing the need to make sure the bolts all extend far enough. The left hand ones need to be 10mm longer to be even.

    Hi Mike. Thanks for the photos. Glad I have seen them. I wouldn't have thought so much needs to be cut away. But now I have seen these I will not be shy
    in cutting and carving the bar out to clear the pipework.
    I take it you have had no trouble with the performance of the IN/OUT cover plate?
    Thanks again.
