After changing to oil pump last night and firing the car up this morning it looks like the car wont be making it next weekend.
After work last night, the car was pushed onto the ramp, the oil was drained and I took the sump off (Wish I hadn't fitted studs insted of bolts as I had to take the starter off :-( ) I took the oil pump off and found it was a Melling but not a High Volumn like I was about to fit. After bolting it all back up I found I did not have any oil and as it was getting late I would not have started it anyway.
This morning I went and bought some 20/50 and a tin of oil treatment and stuck it in, I primed the pump and the oil pressure came straight up, I put the dizzy back in and started it up, 40 psi on fast tickover but after a very short while, it dropped down below 10 again, so I shut it off and gave it a quick check over to see if I could find a problem, when I started it again, it only went to 20 and then dropped straight back down to less the 10.
I've taken the battery off and put the car back outside for now, I have been asked to take it to a garage open day and a small show in the next few weeks, so after that, the engine will be coming out and crank checked, if OK new bearings will be fitted (I already have a new set of big ends) and hopefully be out fully painted and running next season.
I had a straight 6 jag lump do that to me. It was crap in the oilways in the crank blocking it up. It was caused by wear from the bigend shells.  |

When the crank comes out (Hopefully next weekend) it will be checked and fully cleaned out. (Also the block will be fully cleaned) I am hoping the damage is limited to the bearings as all I would need is some main and cam bearings and a complete gasket set. (Heres hoping  ) |

worse than I thought cabman, but do able  Last night I started to strip the engine down, as normal we pushed the car onto the MOT ramp and took the body off. It was not long before the engine was ready to come out.  The Cunning Coupe  The Cunning Coupe But by now it was getting late so I arranged with Del to be there this morning at 10. We had the engine out in no time and set it up on the stand so I could have a look inside, at that time I could not see a lot, but when I was taking the end cap off No 3 big end there was lots of play, once off I could see the problem it had spun the bearing! I took the crank out and sat it on the ramp to take some photos.  The Cunning Coupe  The Cunning Coupe  The Cunning Coupe I will be phoning up a local company on Monday to see if it can be saved, its already +20 but I don’t think it’s that bad. I am more worried about the rod and will give that to them as well. At the moment I have left the pistons in the block, but as there is lots of sludge in there, there’s will be coming out and the whole lot fully cleaned out.  The Cunning Coupe More news when I have it. (The cam and bores are in great condition) |

Spun the bearing? So what exactly's happened Tony? The bearing's seized & turned with the crankshaft?

Your spot on, it where the bearing sticks to the crank and turns inside ether the con rod or main bearing caps. Hopefully its just the crank that needs a grind, if it needs a new con rod, they are only 20 quid, |

That`ll do it. I was told it`s a common problem with big engines but more especially with jags. You could be lucky and only need to take off the siezed metal from the shell, did that to a Bonnie crank and actually peeled the metal away from the crank journal and all was ok.
Best of luck with it.

That looks like the shell was too tight on the journal. I would expect both sides of the journal to show signs of stress if it was an oil feed issue. Measure the rod eye and compare it with the others and check for true between gudgeon pin bush and big end to eliminate twist. Failing that it could be a rogue shell. Good luck |

Lyons are picking up the crank, rod & piston & block up tomorrow, I have found heavy scoring on No 1 main bearing and marks on most of the others  they are going to check out the crank and the con rod to see they can be saved and the block is going to be hot dipped and cleaned out. More news when I hear from them, A new rod is 20 quid, a recon crank 155 and a new stroker crank just under 300, plus all new bearings and gaskets. It might have to go on hold until after Christmas, lets see what happens  |
