doh   of cours there isnt, thats all internal to the cooler plate.

Will still be some time next week as need to get some pips and jubilees oh and some more oil. Already used 10lts of gen vx oil. Need some more now.
Wish my tradecard would hurry up its costing a fortune  

At least it will have had a good flushing

[gstylebaby]

Sounds bad mate hope you get it sorted sorry i'm no help.

[kingplym]

i know you can self pressure test the water system by stick a tyre valve in a cap, etc. im wondering if you can do the same with an oil cap and with the plenum and injector rail off etc, get a foot pump one with a pressure reading on it, pump away and see were oil leaks from.

just an idea and im not sure what pressure you can pump it to if you can do it at all :-?

goodluck

If it's leaking this fast, you could probably strip out the intake plenum, manifold and spacer, remove the main and fuel pump relays to disable the ignition, fuel pump, etc. and crank the engine over on the starter while watching in the valley (remove the spark plugs to help it spin faster).

This will build up oil pressure after a few seconds cranking and I suspect the leak will become obvious.

I tried that Kevin but with no success. The only thing I didnt do was remove the spark plugs.

I found it wasnt turning over fast enough to build up enough pressure.

It will spin over a lot faster and for longer without the plugs

[star_whites]

Ok well it sounds like its time to strip her down again then.

Looks like tomorrow nights job sorted!....Lets pray for no rain lol

I really admire your persistence.  I would have given up by now. (Although I probably would never have started it in the first place due to my lack of mechanical knowledge).

I cant see it being the heads as the main pressurised oil feeds are on the exhaust side of the heads.

If it was the large nuts that secure the cooler to the cooler plate you would get a water leak, not an oil leak.

As said, spin it over with no plugs in and the relays out for 60 seconds or so to see where its coming from

The HG was 1 of the 2 things I could think of, seeing as oil pipes now rulled out. Other was cam cover/gaskets that side...

[Matchless]

I think the oil feed to the heads comes up on the valley side of each head, mid way along. I wonder if there are cross drillings from this feed to the main gallery and T vents, and is there a missing blanking bolt?

[Omegatoy]

how long had the engine stood before you got round to repairing it?

[star_whites]

It wasnt stood at all. I was running it and it had a bad water leak and as we had stripped half the bits off searching for it, when we found it was the rear corner of the rh cylinder head we decided we may as well carry on and finnish it. So we stripped it down and started the repair.

In total I would say we have been four weekends carrying out the repair from start to finnish.

The leak has got to be in the V as it runs both down the back and the front and fills all the gaps in the V with oil. No oil has made it back to the water tank and there is no sign of oil in the water when stripping down. There is also no sign of water in the oil either.

This led me to think the oil cooler pipes as there is no oil residue on the side of the heads or the injector rail/spacer as you remove it. It is only in the V where the oil cooler is. That whats led me to think oil cooler.

[Omegatoy]

aha ok thats my theory out of the window then!!! i wondered if the oil pressure relief valve had stuck and was blowing the weakest part of the system!!
had it on two engines first one blew the oil filter up ike a balloon before it split, 2nd one it blew the oil seal to smithereens and pumped about 3 litres oil out in about 15seconds of running!!!

On this point Mark, what if the threaded section underneath the nut had cracked. The washers pull the union down onto the top of that threaded section but I do know there is a mm or two stuck up so if the crack was in the threaded section oil could escape couldnt it??
