Well after my engine rebuild: 1.6 bloke
Woesener piston an Conrod (std compression)
Ported Head 3 seats valve
piper cam 285t
stage 2 turbo
group A coil
turbosystem Chip
mongosse
.........

All this on MFI (i know it s not the best)
I putted a 5th injector but i never could set it up and the engine stalls and never start again up and the result was a sinked engine with full of fuel fuel every where in the Sump intercooler pipes......
What i did i take the contaminated oïl off new filter new oïl but i couldn t start the engine anymore

I left it for 2 years few weeks ago i tried the trun the crankshaft and everythings was bloked couldn t turn the camshaft Nothing
so i put a smal amount of oïl into the spark plug holes and the engine turn free again by hand

but now my problem is the compression piston1 : 58 psi only
piston 2 : 58 psi
piston 3 : 58 psi
piston : 130 psi
By cold engine as it do not starts.

so i put again oïl in the spark plugs holes to see if the piston rings wich are NEW mayby bad running in because i used directly full syntethic oïl after rebuild .
piston 1 :116 psi
piston2 : 130 psi
piston 3 : 100 psi
piston 4 :175 psi

i took the rocker cover of Nothing special to see

So what going on ? piston rings fucked?

many thanks guys

(sorry for all thes threats open )
