"A nasty garage man put a ball bearing in the engine"

I think the fact the head and block are clearly from different engines is a pretty clear indicator of the bullst level here - let alone the crazy price
What am i missing here? they look as though they would go together likewell things that go together what is it that makes you think they are from different engines?
My friend took his car for a check over at a well known Cosworth "specialist" in the Midlands... Bearing in mind the car was running perfectly before being dropped off, it was returned with a death rattle and the "specialist" saying that he was only just starting the power runs when it started rattling, and that he advised the car not to be driven, and that it was most likely the bottom end bearings. He could of course, do a very good price on a rebuild as the car was already there...
My friend declined, and got the car recovered to a mates garage, who removed the engine, and took the head off, and removed the sump. The engine was perfect..... On removing the inlet manifold, sitting ontop of one of the #1 inlet valves, was the inner race of a bearing assembly, which AMAZINGLY enough, was just too big to drop into the cylinder via the valves, but small enough to rattle around enough to make a horrible noise .. Bearing in mind, that to get into the engine, this item would have had to go through the air filter, then through the core of an intercooler!! Now, you tell me how that got there, the engine & ancillerys were thoroughly stripped, and nothing was wrong with any part of that car, and the bearing race was not part of the engine!
There are sly bds everywhere, sadly proving it is the impossible thing...

just because the block and head have different ports doesn't mean they don't go together as often the gasket has small ports to restrict flow where as the head and block have big holes to allow for easier core when sand casting

yup, they are pics of a rover dismal engine....just because the block and head have different ports doesn't mean they don't go together as often the gasket has small ports to restrict flow where as the head and block have big holes to allow for easier core when sand casting
pretty shoddy trick, seen this a few times in the distant past, can't believe people still do this st.
heres a couple of pictures of a genuine 1960's 'mowog' alloy cross flow eight port head off a customers race mini.
this had just been 'rebuilt' by an engine builder, who left the spring shims out from under the valve springs, so all the spring preloads where wrong. once the motor really filled its lungs up and started to rev (past 8000rpm) it dropped a valve........
you can see the stem of the valve rammed up through the guide.
due to the rarity of this head, it was welded up, ground out, rewelded, ground out until the chamber came back, new seats where fitted and has done another three seasons racing.....
you cant do that with a cast iron head!

No pics sadly, but a friend had a valve drop on a Honda B16 engine a couple of years ago. Not only did it destroy the head and piston of the cylinder that dropped the valve, a chunk of smashed up valve managed to make it all the way back into the plenum and then back down into another cylinder and knackered that as well.

A ball bearing? Really?
They look like typical detonation pits, I would guess that the injector for that cylinder was giving up and running very very very lean.
Diesels are designed to run on detonation... so even running very lean, you wouldn't get pits like that.They look like typical detonation pits, I would guess that the injector for that cylinder was giving up and running very very very lean.

It doesn't look anything like detonation damage, not even close.They look like typical detonation pits, I would guess that the injector for that cylinder was giving up and running very very very lean.

Compression ignition is not the same as detonation. The fuel in a diesel is burnt in a controlled manner as it is injected.Edited by Mr2Mike on Thursday 15th March 12:12
