Engine rebuild, stiff when trying to turn over (new rings and bearings)

[turbominicooper]

As in the title just fitted new rings and big end bearings.

Used plastigauge and got the following:

Piston 1 - 0.048

P2 - 0.048

P3 - 0.035

P4 - 0.038

Torqued bolts up 20 and then 40nm

is ok turning on pistons 2+3, gets stiffer on 4 and then jammed on 1.

What's the next step here?

Cheers

Fyi acl standard 4efte bearings

k so since my first post ive gone over everthing again and re-sat bearings, torqued etc.

this is how ive got the engine turning:

to me seems tight, i read somewhere that an engine should turn with 25nm torque but this is way over 50 -thoughts?

really want to get this right so any input b great ta

means a bearing is to tight amigo

have u measuring toools to measure the bearings and hole itselve ??

check the nr1 again with plasigauge because u should be able to turn the engine by hand if the pully is on it if you cant its to tight and will destroy the bearing and burn the lobe
