RIGHT HERES THE RESULTS FROM THE COMPRESION TEST FROM MY 87 S2 RS TURBO ESCORT
CYLINDER 1 110 PSI
CYLINDER 2 50 PSI
CYLINDER 3 150 PSI
CYLINDER 4 150 PSI

SO I RECKON IT IS THE RINGS IN 1 AND 2
ANY 1 ELSE GOT ANY IDEAS

AND NOT JUST TO TORCH THE CAR USEFULL IDEAS CHEERS

 

may also be valves,or holed pistons on the 2 low cylinders or cracked head or blown gasket but EITHER way the head will have to come off to find out 100%!

what was the engine doing before you had the problem?

 

WAS SMOKIN ITS NUTS OF AND SLUGGISH LIKE RUNING ON 3 SO THOUGHT WAS THE TURBO GOT A BOTTOM END WITH OVER SIZED PISTONS OF A FRST THO SO GUNNER WACK THAT ON AT THE WEEKEND SEE HOW IT GOES

 

Can you not get access to a cylinder leakage tester? Would pinpoint where the pressure is going.

 

No m8 but cylinder 2 exaust port is covered in oil and every time i hit boost its beloves out loads of smoke

 

my guess would be head gaskets gone between cylinder and oilway

the rings going on just one cylinder seems very unlikely

 

CHEERS 4 REPLY DOSENT LOOK LIKE JUST 1 FROM RESULTS THO AS 2S WELL DOWN AND 1NS GETTING THERE

 

WOULD THERE BE LOADS OF MOVEMENT IN THE TOP OF THE PISTONS WHEN I TOOK THE HEAD OF THAT I COULD NOTICE ANYWAY

 

Took the head of there looks nothing un normal apart from all thye crap on the block top, barrels are all smooth no rocking in the pistons, all the holes were blocked up with crude any ideas any1 im thinking gasket now so might just bolt it all back together see what happens
