Re: Reground, crank duff?.

Core plugs are all in place,no sign of leakage, bearings were showing quite a lot of copper and the crank was oval, can't remember by how much.

Re: Reground, crank duff?.

No, that's when i knew something was wrong because i've been watching engine rebuilds on utube, you need both hands on the webs to turn this and it marks the front shell, anyone got a block for sale?.

Re: Reground, crank duff?.

Yes i've been looking around that area, i can see casting marks and ridges, as for cracks no but then again they could be tiny, the engineer who deals a with tuned mini engines from a local firm said it was a very rare but not unkown for blocks to do this, just had it rebored and honed too :( .

Re: Reground, crank duff?.

The crank was checked on two blocks and a dial guage on the centre by an engineer, i watched him do it, the shells were checked against the crank size that was okay so he put a streight edge on the block and a feeler guage did go down one side of the centre casting on the block showing it was out, h...

Re: Reground, crank duff?.

Had the crank checked and it's within tolerance, the shells match and the crank, I was told it's the block! centre bearing casting is slightly off and will need line honing too correct the problem.

Would it last once done or is it likely to move again and bind?.

Re: Damper

Yes i've spent quite a lot of money on the engine but I had too because it was shot, so I wasn't relishing the idea of another ninty quid on a damper, I believe lightening the flywheel is beneficial from pickup and would improve the 0-40 mph time not because i want to use the higher end of the rpm m...

Re: Cam wear

That's a thought but it would have to be a 998 cam because i don't want too fiddle around getting the new oil pump to fit, also i'm fitting a 1275 head so i only want the same lift as as a Minor cam.

Re: Torsion bar

Thanks for the tip, but Iv'e thought of maybe another way around it, if I undo the top link and reconect the bottom, then used some thick wire to bind the top link together tightend with pliers!, it's just a rolling shell so should be ok :-?

12g940 head

Hi all, got myself a 12g940 head today from an 1974 Marina i'm told, somebody in the past has had the same idea about useing it on a small block engine because one of the exhaust valve seats has already been recest a little to far it looks to me. The distance between the head face and the valve is 1...

Re: Bumpers

Ok, thanks for the feedback all, there are no bumper irons on the back anyway but I need a towbar so that will do for a bumper, one front iron is falling off, i'll weld it back on then make up a tubular bar from steel pipe to go beteen the two, I agree about the headlamp eyelids, naff.
