After having a shit RR figure and knowing that my frst was down on compression i decided to get physical with it... with help from manchester mike we stripped the engine down and found this...





I'm guessing that the chunck brocken between the rings caused it...

Now to sort it out... They are mahle +0.5 pistons, only seem to have any damage on one of them... should i change that one or is it better to change them all? also while they are out should I change the rings? they are pretty sharp, i've been told this is a sign of ware?

Also where can i get my hands on a +0.5 piston cheap, and do I have to replace with mahle or can i use something else such as AE?

Cheers in advance

 

Oh dear , ive got the odd 1 layin about yours for a drink

 

p.s look for black det spots on the rings but there not expensive so be a good move IMO
Been lean or detin thats for sure.

 

22psi through a t2 on beige's and std cooler should give u some idea...

 

is the damage on the exhaust side or inlet side of the piston.. ???

 

looks like exh

 

 

 

at least its not too bad to sort out Sean.

Should not take you long.

 

MASSIVE

 

Lol, easy to sort. Bearings are really nice, rings have no set markings, bore's are all good.

BTW Tim, the tie bars are on - cheers mate

 

Cheers Tim Top bloke

There will be a few drinks for you at the ring if your going

Can i just point out that it was runing that b4 i bought it!! It has been set up by MSD since

 

Didn't u phone me a few months ago asking about the brass screwy thing?

 

lmao

 

pm me sean so we can sort it

 

 

was your engine running seemingly ok though concidering what you found ? but with lack of power ?

 

yeah fine... it was still producing just short of 150bhp but i obviously knew something was up and wanted to find out what and sort it.
