Blydenstein Engine update & Mazzo’s dead engine
I have not done an update on any of the engines in build for a while, and I thought I ought too. Just to recap folks I have a 1256cc engine in build for the new owner of my old HA (Marvin).
Mark’s 1256cc engine I have not done a great deal more other than dig out the brand new set of cam followers and the Piper camshaft and fit those to the block. I have also dug out all the new bearings for the crank, the lightened flywheel, con rods, pistons and a few other items and will in the next week or so have them up to Bill the Balancer for him to cast his miracle eye over. The crank will need a regrind and Jason who works with Bill can play with that. Just to remind you this is the engine:
Whats prompted this update, other than to say what I have already said? Well a good friend of mine Mazzo had some bad luck on the M40 yesterday, the car appears to of self destructed its own engine. In his own words:
Alas my trusty 1159 HC engine died today. It’s done just under 85000 miles and is basically untouched (not rebored or anything). Today I was driving on the motorway and all of a sudden it sounded rough (like the big end was knocking) so I pulled onto the hard shoulder. I was driving quite gently too.
I checked the oil which was fine. The temp was fine. Let it cool a bit and tried to start it. Eventually it did and made a hell of a noise – quite loud clanking and within about 3 seconds if that, went bang. 😯
Basically it punched something through the sump. Anyway, it is dead but at least the block is OK or should be, so it may live again one day.
After a 30 minute natter on the phone whilst awaiting rescue on the motorway he sent me this picture showing a nice new vent hole in the sump. I suspect a Big end cap let go?
Today Mazzo has taken the head off and found out its defiantly number two bore at issue, as the piston has dropped down. It should be on the same rotational cycle as number three (which is shown at the top of the bore).
So its coming back to the Shed of plenty for a once over and see if it can be rebuilt as a spare for Mazzo. Luckily for Mazzo he has a spare engine for which I shall go and assist him with fitting in the next few weeks. The bore doesn’t look to bad, but who knows what horrors lie inside the sump?
