Good and bad sides of oil pump. https://uploads.tapatalk-cdn.com/20240427/ecb0aef283d22c9555c448ac1338169e.jpg https://uploads.tapatalk-cdn.com/20240427/93fa1d25ee993cd6face1d0ea0a76cc1.jpg https://uploads.tapatalk-cdn.com/20240427/847ecbc99d6d487e17b3ab998a526178.jpg https://uploads.tapatalk-cdn.co...

Sorry I didn't get a photo, but when I got into the 2nd chamber of the oil pump, I found no aluminium chunks. But it was starved of oil, and the oil pump case was corroded, causing it to be jammed. It turns out I could probably have forced the crank round without doing too much damage to anything. T...

That little piece of alloy has stamped on it the numbers 84V5, which is a fragment of the stamping 84V55 which are the dimensions of the pistons, and features in the casting inside them. I checked all the pistons for missing chunks and there were none, so it would seem that this engine has failed im...

Ok so I gave the Internet a few days to critique my proposed solution, or come up with a better one. I wasn't that keen on putting a grinder inside the engine as I know how they can grab and shoot across and instantly take a chunk out of something. Here goes nothing... https://uploads.tapatalk-cdn.c...

Original 1970 tank seen here viewtopic.php?t=68983&hilit=petrol+tank ... e&start=45

72 is the same i'd guess?

The allen key is the drain plug. The others - one is send and the other return I think. Looks original to me. Does it have a thick plasticky underseal type material all over it? Grey if I remember correctly.

Sell the fuel tank on ebay (or on here). That will fill a gap for somebody, and people value originality. If anyone wants it happy for it to go free to a good home. I’m not sure if it’s original or not. Sure someone with the skills and time could restore it. PM me if any interest. Sent from my iPho...

I thought Mike had retired? Hopefully he still wants to share his experience. Don't the pistons pass through the cylinder holes in the block halves? That lump of alloy jamming the piston should tap back into the case where it dropped in from? Do the rods move on their big ends or tight? When my 3.2...

Thanks, that's most kind of you, (if it comes to that).

I might drop Mike Bainbridge a line as I'm sure he has dealt with this eventuality on multiple occasions.

Perhaps you’ll need to drill or cut the piston to get access to the rod bolts, ideally without damaging the rod? I contemplated that but I'd have to do both, and one is a good piston (one broken). A new oil pump driveshaft is £60. A new piston, more. Although in truth, I'm probably replacing all th...

If you can get a set of three pistons off and then release half of the crankcase you can maybe get to whatever is jamming it, or to the other rod bolts and then it should come apart. Just put the engine stand connection on the side with the stuck pistons pointing towards the floor and leave the cra...

Being entirely satisfied that it is the seized oil pump that's preventing the crank from turning, I formed a plan to break away these circlips and see if I can slide the centre of the oil pump driveshaft off its splines in one direction, allowing the crank to turn. https://uploads.tapatalk-cdn.com/2...

I have no clue where this is going because 3 and 6 are irremovable but it feels like a step forward in some sense. https://uploads.tapatalk-cdn.com/20240425/5322ec617f8c5847f6ded8c425888443.jpg https://uploads.tapatalk-cdn.com/20240425/723cb5e4c3b251471396336c44a4738d.jpg Sent from my SM-G988B using...

Oil pickup contains metal flakes - feels like magnesium.
