hy this winter I gonna change some spec of my car new gearbox new cylinder head...

my engine was rebuild only 1620 miles ago

I took the cylinder head off
and saw that cylinder 1 and 4 are more dirty thath 2 and 3 ???why this




and I saw some scratch in 2 zylinder one scratch I can fell a little bit with my finger



whats about my new piston rings need to chang them again?...

 

well I decided I gonna remake de again from A to Z

the motor block sand cleaning (before I did it with the brusches)..
repainting the block

and
new H rod for the safty

what about the piston rings new again new ones because the little scratch?

 

I had a engine with a bit of a scratch, it didn't appear to effect it in the time I used it, it wasn't a great engine anyway.

What inlet manifold are you using?

 

standard s2 inlet my 4 injecotor fuel up the same quantiti

 

I'd suggest new piston rings will do nothing to help the scratches in the bores and be wondering how the scratches got there if it's not long rebuilt.
I'd also be worried if two piston tops were so different in appearance than the other two?

 

Is that detonation marks on the top of the pistons? (Hard to see in those pics).

 

no detonation the piston are in good condition they are very flat on the surface only that number 1 and 4 are more dirty also on the cylinder head in the combustion chamber.. (didn't no that the standard piston are MAHLE )

BUT CARFULL WANT I FOUND KNOW LOOK GOOD ON THE FIRST PICTURE YOU CAN SEE LITTLE BIT THAT THE PISTON 4 IS LOWER THEN THE NUMBER 1
HER IS THE ANSWER
whats wrong in this picture?

yes very lucky that I open again the engine only 1600 miles ago
lucky that I didn't broke ( I directly bought some H conrods )


I think it s from to mutch boost 17psi on old standard conrods

also one bearing is in bad condition only 2 from one conrod


all the other looks more normal


my crankshaft it s OK

 

Holy shit Lucky bastard! The crankshaft you only see the middle piece on one of the taps. Isn't that one a bit worn?

bad bearings are also from the bend conrod?

 

well I mesure them before I bought the bearing and they had the standard mesure so I bought the standard CVH bearing and I also had always 1 bar oil pressure on idle
I don't know if the new H conrods comes with bearing ? think not
I gonna mesure them all again and give the result to know wich I need to buy

 

I just got my H conrods one question what kind of circlip are one the standard mahle piston and how to take the best way the cylinder out....

I also took the LSD from the box out gonna fit it in a ib5 escort mk5 1.4

 

If you got standard pistons u need to get a machine shop to make them fully floating to make your rods fit correct

 

yes I gonna give they to somebody they need to warm they up to fit it no?

but what kind of circlip have the standars mahle piston
