I see,and this caused a lack of oil pressure?The pump was pumping,but not being forced into the block? One of my Atoms has the relocation kit and maybe it is worth looking at this seal... :H:

It was the oil seal in the oil-filter relocation kit.
(Basically the spring holds down an oil seal where the filter used to be.)

Which oil seal failed to cause all the problems?

Update.

It turns out that an oil seal was faulty.  The bottom of the engine has now failed.

Shinoo and Sector 111 have kindly stepped forward and are going to rebuild the engine.
It looks like this latest adventure will soon have a happy ending.

What Terry says is true, several of us have changed pistons with the engine in the car.  Brass in the oil does not sound good though and the crank journals are what I was thinking also.  Which will get to that oil pressure question.

Any idea what the "other" is? I've had my engine oil tested at each change since the Atom was new, and there has never been any brass in the samples, not even from wearing in.

Can you drop the oil pan to inspect the crankshaft journals? You don't need to take the engine out of the car for this - with careful wiggling you can get by w/ just removing the passenger-side motor mount bolts and jacking the engine up about 1/4".

With that and a borescope looking down the cylinders with the spark plugs removed, you should be able to get a quick overview of the major engine components.
I'm not very happy right now.

No wca for me.
Can you come up just for the social events?

OuchAAAAARG!!  Man, sorry Nick.         

I can't help it though;  I'm thinking "Maybe Nick will build some insanely fast bullet proof beast from the damaged motor".  But sometimes my positive thinking happens at unappropriate times.

That's a real bummer, Nick... I hope that your engine problems are swiftly fixed! Any chance of you coming up just for the party? :)

Hopefully it was just the tensioner/chain flailing about. But metal circulating about is not good..

Not really certain were there is brass in an aluminum engine, usually once you get to the brass there are large aluminum pieces on the track behind you.

Sorry to hear that Nick, I was hoping it was just your tensioner ...

Any update on this? I'm beginning to pack and need to know if I need to bring my own beer..  ;D

Does it do it more/worse at start up until oil pressure comes up?

Have them check to make sure that the cams are still in time as they can jump without tensioner.

What happens is the chain goes slack between the cams then slaps and the tensioner goes full stroke and slaps.

your header is coming loose

tighten it up


almost guarantee that's the problem as I had the same and we have the same exhaust

sounded like it was internal but it's not


I posted a video of it here lemme search for it
