I bought a cosworth baffle plate for my closed deck block, and when i tried to fit it yesterday i found out it doesn't fit at all. The two vertical plates on the back of the baffleplate hit the block and the baffleplate doesnt fall in place.

There is a huge gap between the block and the plate:




Looking through this hole you can see the vertical plate touching the block:


And the baffleplate removed:

 

I had to trim mine to get a fit. Also on a cdb.

 

How did you trim yours? Just cut a piece of with a saw or something? And how much am i supposed to trim? How much space should be between the plate and the block?

 

On some blocks the vertical pieces need trimming with a whizzy wheel or file (make sure you cleana thoroughly afterwards). Just trim til the plate sits flush.

 

Does there need to be any space between the vertical pieces and the block? Or do i need to trim te pieces until the plate just fits the block?

And what is a Whizzy Wheel? I'm dutch, and my english isn't thát good

 

Oh sorry - a Dremel or similar

 

All that money, An you have to trim it madness

 

+1

 

Same on a STI V4 engine, had to trim it.

 

Could you tell me how you trimmed it?

 

It seems that center thrust engines will all need trimmed to let the plate down. The channel/cut out is not long enough to allow it to sit down.

 

I presume it is better to take more than is needed out of the vertical leg, so that you are guaranteed the sump can seal correct against the block

 

Thats really poor IMO, i wouldnt be happy with that at all.

 

They were designed for the EJ207 but need a little 'fettle' to fit the center thrust blocks.
Needs approx 2.50mm removing to clear the webs and its prudent to remove the rubber flaps to clean the swarf out properly.

The genius is here

 

Hows the running in going ??

 

ah fair enough then i guess if its trying to be fitted to something different from that it was originally designed for...

 

Fitted one to my EJ257 without any issue whatsoever.

As above the problem seems to only be with closed deck centre thrust blocks.

 

Very well thanks Mick,had afew teething problems but nothing major by any means so im well chuffed,200 miles more and then full fat map time on the 30th

 

This might help the OP




Fitted to CDB

 

As they said, it's just on the centre thrust blocks.
Sometimes, when modifying, it's no pain, no gain!

 

Superb
And give yourself a pat on the back for taking it on and doing it yourself !!

Is this also the case for the rcm baffle plates?

 

Sorry I know this is an old thread but couldn't find anything else on it.
